For multipart bodies, you may be interested in the following\nmodules:\n\n * [busboy](https://www.npmjs.org/package/busboy#readme) and\n [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)\n * [multiparty](https://www.npmjs.org/package/multiparty#readme) and\n [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)\n * [formidable](https://www.npmjs.org/package/formidable#readme)\n * [multer](https://www.npmjs.org/package/multer#readme)\n\nThis module provides the following parsers:\n\n * [JSON body parser](#bodyparserjsonoptions)\n * [Raw body parser](#bodyparserrawoptions)\n * [Text body parser](#bodyparsertextoptions)\n * [URL-encoded form body parser](#bodyparserurlencodedoptions)\n\nOther body parsers you might be interested in:\n\n- [body](https://www.npmjs.org/package/body#readme)\n- [co-body](https://www.npmjs.org/package/co-body#readme)\n\n## Installation\n\n```sh\n$ npm install body-parser\n```\n\n## API\n\n<!-- eslint-disable no-unused-vars -->\n\n```js\nvar bodyParser = require('body-parser')\n```\n\nThe `bodyParser` object exposes various factories to create middlewares. All\nmiddlewares will populate the `req.body` property with the parsed body when\nthe `Content-Type` request header matches the `type` option, or an empty\nobject (`{}`) if there was no body to parse, the `Content-Type` was not matched,\nor an error occurred.\n\nThe various errors returned by this module are described in the\n[errors section](#errors).\n\n### bodyParser.json([options])\n\nReturns middleware that only parses `json` and only looks at requests where\nthe `Content-Type` header matches the `type` option. This parser accepts any\nUnicode encoding of the body and supports automatic inflation of `gzip` and\n`deflate` encodings.\n\nA new `body` object containing the parsed data is populated on the `request`\nobject after the middleware (i.e. `req.body`).\n\n#### Options\n\nThe `json` function takes an optional `options` object that may contain any of\nthe following keys:\n\n##### inflate\n\nWhen set to `true`, then deflated (compressed) bodies will be inflated; when\n`false`, deflated bodies are rejected. Defaults to `true`.\n\n##### limit\n\nControls the maximum request body size. If this is a number, then the value\nspecifies the number of bytes; if it is a string, the value is passed to the\n[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults\nto `'100kb'`.\n\n##### reviver\n\nThe `reviver` option is passed directly to `JSON.parse` as the second\nargument. You can find more information on this argument\n[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).\n\n##### strict\n\nWhen set to `true`, will only accept arrays and objects; when `false` will\naccept anything `JSON.parse` accepts. Defaults to `true`.\n\n##### type\n\nThe `type` option is used to determine what media type the middleware will\nparse. This option can be a function or a string. If a string, `type` option\nis passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)\nlibrary and this can be an extension name (like `json`), a mime type (like\n`application/json`), or a mime type with a wildcard (like `*/*` or `*/json`).\nIf a function, the `type` option is called as `fn(req)` and the request is\nparsed if it returns a truthy value. Defaults to `application/json`.\n\n##### verify\n\nThe `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,\nwhere `buf` is a `Buffer` of the raw request body and `encoding` is the\nencoding of the request. The parsing can be aborted by throwing an error.\n\n### bodyParser.raw([options])\n\nReturns middleware that parses all bodies as a `Buffer` and only looks at\nrequests where the `Content-Type` header matches the `type` option. This\nparser supports automatic inflation of `gzip` and `deflate` encodings.\n\nA new `body` object containing the parsed data is populated on the `request`\nobject after the middleware (i.e. `req.body`). This will be a `Buffer` object\nof the body.\n\n#### Options\n\nThe `raw` function takes an optional `options` object that may contain any of\nthe following keys:\n\n##### inflate\n\nWhen set to `true`, then deflated (compressed) bodies will be inflated; when\n`false`, deflated bodies are rejected. Defaults to `true`.\n\n##### limit\n\nControls the maximum request body size. If this is a number, then the value\nspecifies the number of bytes; if it is a string, the value is passed to the\n[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults\nto `'100kb'`.\n\n##### type\n\nThe `type` option is used to determine what media type the middleware will\nparse. This option can be a function or a string. If a string, `type` option\nis passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)\nlibrary and this can be an extension name (like `bin`), a mime type (like\n`application/octet-stream`), or a mime type with a wildcard (like `*/*` or\n`application/*`). If a function, the `type` option is called as `fn(req)`\nand the request is parsed if it returns a truthy value. Defaults to\n`application/octet-stream`.\n\n##### verify\n\nThe `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,\nwhere `buf` is a `Buffer` of the raw request body and `encoding` is the\nencoding of the request. The parsing can be aborted by throwing an error.\n\n### bodyParser.text([options])\n\nReturns middleware that parses all bodies as a string and only looks at\nrequests where the `Content-Type` header matches the `type` option. This\nparser supports automatic inflation of `gzip` and `deflate` encodings.\n\nA new `body` string containing the parsed data is populated on the `request`\nobject after the middleware (i.e. `req.body`). This will be a string of the\nbody.\n\n#### Options\n\nThe `text` function takes an optional `options` object that may contain any of\nthe following keys:\n\n##### defaultCharset\n\nSpecify the default character set for the text content if the charset is not\nspecified in the `Content-Type` header of the request. Defaults to `utf-8`.\n\n##### inflate\n\nWhen set to `true`, then deflated (compressed) bodies will be inflated; when\n`false`, deflated bodies are rejected. Defaults to `true`.\n\n##### limit\n\nControls the maximum request body size. If this is a number, then the value\nspecifies the number of bytes; if it is a string, the value is passed to the\n[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults\nto `'100kb'`.\n\n##### type\n\nThe `type` option is used to determine what media type the middleware will\nparse. This option can be a function or a string. If a string, `type` option\nis passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)\nlibrary and this can be an extension name (like `txt`), a mime type (like\n`text/plain`), or a mime type with a wildcard (like `*/*` or `text/*`).\nIf a function, the `type` option is called as `fn(req)` and the request is\nparsed if it returns a truthy value. Defaults to `text/plain`.\n\n##### verify\n\nThe `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,\nwhere `buf` is a `Buffer` of the raw request body and `encoding` is the\nencoding of the request. The parsing can be aborted by throwing an error.\n\n### bodyParser.urlencoded([options])\n\nReturns middleware that only parses `urlencoded` bodies and only looks at\nrequests where the `Content-Type` header matches the `type` option. This\nparser accepts only UTF-8 encoding of the body and supports automatic\ninflation of `gzip` and `deflate` encodings.\n\nA new `body` object containing the parsed data is populated on the `request`\nobject after the middleware (i.e. `req.body`). This object will contain\nkey-value pairs, where the value can be a string or array (when `extended` is\n`false`), or any type (when `extended` is `true`).\n\n#### Options\n\nThe `urlencoded` function takes an optional `options` object that may contain\nany of the following keys:\n\n##### extended\n\nThe `extended` option allows to choose between parsing the URL-encoded data\nwith the `querystring` library (when `false`) or the `qs` library (when\n`true`). The \"extended\" syntax allows for rich objects and arrays to be\nencoded into the URL-encoded format, allowing for a JSON-like experience\nwith URL-encoded. For more information, please\n[see the qs library](https://www.npmjs.org/package/qs#readme).\n\nDefaults to `true`, but using the default has been deprecated. Please\nresearch into the difference between `qs` and `querystring` and choose the\nappropriate setting.\n\n##### inflate\n\nWhen set to `true`, then deflated (compressed) bodies will be inflated; when\n`false`, deflated bodies are rejected. Defaults to `true`.\n\n##### limit\n\nControls the maximum request body size. If this is a number, then the value\nspecifies the number of bytes; if it is a string, the value is passed to the\n[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults\nto `'100kb'`.\n\n##### parameterLimit\n\nThe `parameterLimit` option controls the maximum number of parameters that\nare allowed in the URL-encoded data. If a request contains more parameters\nthan this value, a 413 will be returned to the client. Defaults to `1000`.\n\n##### type\n\nThe `type` option is used to determine what media type the middleware will\nparse. This option can be a function or a string. If a string, `type` option\nis passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)\nlibrary and this can be an extension name (like `urlencoded`), a mime type (like\n`application/x-www-form-urlencoded`), or a mime type with a wildcard (like\n`*/x-www-form-urlencoded`). If a function, the `type` option is called as\n`fn(req)` and the request is parsed if it returns a truthy value. Defaults\nto `application/x-www-form-urlencoded`.\n\n##### verify\n\nThe `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,\nwhere `buf` is a `Buffer` of the raw request body and `encoding` is the\nencoding of the request. The parsing can be aborted by throwing an error.\n\n## Errors\n\nThe middlewares provided by this module create errors depending on the error\ncondition during parsing. The errors will typically have a `status`/`statusCode`\nproperty that contains the suggested HTTP response code, an `expose` property\nto determine if the `message` property should be displayed to the client, a\n`type` property to determine the type of error without matching against the\n`message`, and a `body` property containing the read body, if available.\n\nThe following are the common errors emitted, though any error can come through\nfor various reasons.\n\n### content encoding unsupported\n\nThis error will occur when the request had a `Content-Encoding` header that\ncontained an encoding but the \"inflation\" option was set to `false`. The\n`status` property is set to `415`, the `type` property is set to\n`'encoding.unsupported'`, and the `charset` property will be set to the\nencoding that is unsupported.\n\n### request aborted\n\nThis error will occur when the request is aborted by the client before reading\nthe body has finished. The `received` property will be set to the number of\nbytes received before the request was aborted and the `expected` property is\nset to the number of expected bytes. The `status` property is set to `400`\nand `type` property is set to `'request.aborted'`.\n\n### request entity too large\n\nThis error will occur when the request body's size is larger than the \"limit\"\noption. The `limit` property will be set to the byte limit and the `length`\nproperty will be set to the request body's length. The `status` property is\nset to `413` and the `type` property is set to `'entity.too.large'`.\n\n### request size did not match content length\n\nThis error will occur when the request's length did not match the length from\nthe `Content-Length` header. This typically occurs when the request is malformed,\ntypically when the `Content-Length` header was calculated based on characters\ninstead of bytes. The `status` property is set to `400` and the `type` property\nis set to `'request.size.invalid'`.\n\n### stream encoding should not be set\n\nThis error will occur when something called the `req.setEncoding` method prior\nto this middleware. This module operates directly on bytes only and you cannot\ncall `req.setEncoding` when using this module. The `status` property is set to\n`500` and the `type` property is set to `'stream.encoding.set'`.\n\n### too many parameters\n\nThis error will occur when the content of the request exceeds the configured\n`parameterLimit` for the `urlencoded` parser. The `status` property is set to\n`413` and the `type` property is set to `'parameters.too.many'`.\n\n### unsupported charset \"BOGUS\"\n\nThis error will occur when the request had a charset parameter in the\n`Content-Type` header, but the `iconv-lite` module does not support it OR the\nparser does not support it. The charset is contained in the message as well\nas in the `charset` property. The `status` property is set to `415`, the\n`type` property is set to `'charset.unsupported'`, and the `charset` property\nis set to the charset that is unsupported.\n\n### unsupported content encoding \"bogus\"\n\nThis error will occur when the request had a `Content-Encoding` header that\ncontained an unsupported encoding. The encoding is contained in the message\nas well as in the `encoding` property. The `status` property is set to `415`,\nthe `type` property is set to `'encoding.unsupported'`, and the `encoding`\nproperty is set to the encoding that is unsupported.\n\n## Examples\n\n### Express/Connect top-level generic\n\nThis example demonstrates adding a generic JSON and URL-encoded parser as a\ntop-level middleware, which will parse the bodies of all incoming requests.\nThis is the simplest setup.\n\n```js\nvar express = require('express')\nvar bodyParser = require('body-parser')\n\nvar app = express()\n\n// parse application/x-www-form-urlencoded\napp.use(bodyParser.urlencoded({ extended: false }))\n\n// parse application/json\napp.use(bodyParser.json())\n\napp.use(function (req, res) {\n res.setHeader('Content-Type', 'text/plain')\n res.write('you posted:\\n')\n res.end(JSON.stringify(req.body, null, 2))\n})\n```\n\n### Express route-specific\n\nThis example demonstrates adding body parsers specifically to the routes that\nneed them. In general, this is the most recommended way to use body-parser with\nExpress.\n\n```js\nvar express = require('express')\nvar bodyParser = require('body-parser')\n\nvar app = express()\n\n// create application/json parser\nvar jsonParser = bodyParser.json()\n\n// create application/x-www-form-urlencoded parser\nvar urlencodedParser = bodyParser.urlencoded({ extended: false })\n\n// POST /login gets urlencoded bodies\napp.post('/login', urlencodedParser, function (req, res) {\n if (!req.body) return res.sendStatus(400)\n res.send('welcome, ' + req.body.username)\n})\n\n// POST /api/users gets JSON bodies\napp.post('/api/users', jsonParser, function (req, res) {\n if (!req.body) return res.sendStatus(400)\n // create user in req.body\n})\n```\n\n### Change accepted type for parsers\n\nAll the parsers accept a `type` option which allows you to change the\n`Content-Type` that the middleware will parse.\n\n```js\nvar express = require('express')\nvar bodyParser = require('body-parser')\n\nvar app = express()\n\n// parse various different custom JSON types as JSON\napp.use(bodyParser.json({ type: 'application/*+json' }))\n\n// parse some custom thing into a Buffer\napp.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))\n\n// parse an HTML body into a string\napp.use(bodyParser.text({ type: 'text/html' }))\n```\n\n## License\n\n[MIT](LICENSE)\n\n[npm-image]: https://img.shields.io/npm/v/body-parser.svg\n[npm-url]: https://npmjs.org/package/body-parser\n[travis-image]: https://img.shields.io/travis/expressjs/body-parser/master.svg\n[travis-url]: https://travis-ci.org/expressjs/body-parser\n[coveralls-image]: https://img.shields.io/coveralls/expressjs/body-parser/master.svg\n[coveralls-url]: https://coveralls.io/r/expressjs/body-parser?branch=master\n[downloads-image]: https://img.shields.io/npm/dm/body-parser.svg\n[downloads-url]: https://npmjs.org/package/body-parser\n[gratipay-image]: https://img.shields.io/gratipay/dougwilson.svg\n[gratipay-url]: https://www.gratipay.com/dougwilson/\n", |
