url [String]

HTTP 请求 URL。

access_token [String]

GitHub个人访问令牌,请参阅:创建个人访问令牌 - Github文档

method [String]

HTTP 请求方法。目前支持 GETPOST

params [Map]

http 参数

body [String]

HTTP 请求体

poll_interval_millis [int]

流模式下请求 API 的间隔时间(毫秒)。

retry [int]

请求失败(IOException)时最大重试次数。

retry_backoff_multiplier_ms [int]

请求失败时的退避时间(毫秒)乘数。

retry_backoff_max_ms [int]

请求失败时的最大退避时间(毫秒)。

format [String]

上游数据的格式,现在仅支持json text,默认是json

若你的数据格式为 json,需同时配置 schema 选项,例如:

上游数据如下:

{
  "code": 200,
  "data": "get success",
  "success": true
}

您应该配置 schema 为以下内容:


schema { fields { code = int data = string success = boolean } }

连接器将生成如下数据:

codedatasuccess
200get successtrue

若你设置格式为 text,连接器不会对上游数据做出任何改变,示例:

上游数据如下:

{
  "code": 200,
  "data": "get success",
  "success": true
}

连接器将生成如下数据:

content
{“code”: 200, “data”: “get success”, “success”: true}

schema [Config]

fields [Config]

上游数据的字段定义。

content_json [String]

该参数可用于提取一些 json 数据。如果你只需要 “book” 部分的数据,可以配置 content_field = "$.store.book.*".

如果你的返回数据如下所示:

{
  "store": {
    "book": [
      {
        "category": "reference",
        "author": "Nigel Rees",
        "title": "Sayings of the Century",
        "price": 8.95
      },
      {
        "category": "fiction",
        "author": "Evelyn Waugh",
        "title": "Sword of Honour",
        "price": 12.99
      }
    ],
    "bicycle": {
      "color": "red",
      "price": 19.95
    }
  },
  "expensive": 10
}

你可以配置 content_field = "$.store.book.*" 并且结果返回如下:

[
  {
    "category": "reference",
    "author": "Nigel Rees",
    "title": "Sayings of the Century",
    "price": 8.95
  },
  {
    "category": "fiction",
    "author": "Evelyn Waugh",
    "title": "Sword of Honour",
    "price": 12.99
  }
]

然后你可以通过更简单的 schema 配置获取所需的结果,例如:

Http {
  url = "http://mockserver:1080/contentjson/mock"
  method = "GET"
  format = "json"
  content_field = "$.store.book.*"
  schema = {
    fields {
      category = string
      author = string
      title = string
      price = string
    }
  }
}

这是一个例子:

json_field [Config]

该参数用于帮助你配置 schema,因此必须与 schema 一起使用。

如果你的数据如下所示:

{
  "store": {
    "book": [
      {
        "category": "reference",
        "author": "Nigel Rees",
        "title": "Sayings of the Century",
        "price": 8.95
      },
      {
        "category": "fiction",
        "author": "Evelyn Waugh",
        "title": "Sword of Honour",
        "price": 12.99
      }
    ],
    "bicycle": {
      "color": "red",
      "price": 19.95
    }
  },
  "expensive": 10
}

你可以通过如下任务配置获取 “book” 部分的内容:

source {
  Http {
    url = "http://mockserver:1080/jsonpath/mock"
    method = "GET"
    format = "json"
    json_field = {
      category = "$.store.book[*].category"
      author = "$.store.book[*].author"
      title = "$.store.book[*].title"
      price = "$.store.book[*].price"
    }
    schema = {
      fields {
        category = string
        author = string
        title = string
        price = string
      }
    }
  }
}

common options

源插件通用参数,请参考 常用选项获取详细说明。

示例

Github {
  url = "https://api.github.com/orgs/apache/repos"
  access_token = "xxxx"
  method = "GET"
  format = "json"
  schema = {
    fields {
      id = int
      name = string
      description = string
      html_url = string
      stargazers_count = int
      forks = int
    }
  }
}
