-文件上传，当前支持在vertx rest通道和servlet rest中使用。
+File upload, currently supported in vertx rest channel and servlet rest.
-文件上传使用标准的http form格式，可与浏览器的上传直接对接。
+File uploads use the standard http form format, which can directly upload the file from the browser.
-## Producer：
-支持jaxrs和springmvc开发模式
+## Producer:
+Support jaxrs and springmvc development mode
-jaxrs开发模式：
-* 支持servlet定义的javax.servlet.http.Part类型
+Jaxrs development model:
+* javax.servlet.http.Part type that supports servlet definitions
-* 可以直接使用@FormParam传递文件类型及普通参数
+* You can directly use @FormParam to pass file types and common parameters
-springmvc开发模式：
+Springmvc development mode:
-* 支持servlet定义的javax.servlet.http.Part类型，也支持org.springframework.web.multipart.MultipartFile类型
+* Supports servlet-defined javax.servlet.http.Part type, also supports org.springframework.web.multipart.MultipartFile type
-* 两种数据类型功能是一致的，MultipartFile的底层也是Part
+* The two datatype functions are consistent, and the underlying part of MultipartFile is also Part
-* 两种数据类型可以混合使用，比如第一个参数是Part，第二个参数是MultipartFile
+* Two data types can be mixed, for example, the first parameter is Part and the second parameter is MultipartFile
-* 可以直接使用@RequestPart传递文件类型及普通参数
+* You can directly use @RequestPart to pass file types and common parameters
-注意：
+note:
-* 先配置文件上传临时目录，默认为null不支持文件上传，文件上传请求Content-Type必须为multipart/form-data
+* First file upload temporary directory, the default is null does not support file upload, file upload request Content-Type must be multipart/form-data
-* 同名参数只支持一个文件
+* The same name parameter only supports one file
-* 支持一次传输多个不同参数名的文件
+* Supports transferring files with multiple different parameter names at one time
-* 通过MultipartFile或Part打开流后，记得关闭，否则上传的临时文件会无法删除，最终导致上传临时目录被撑爆
+* After opening the stream through MultipartFile or Part, remember to close it. Otherwise the uploaded temporary file will not be deleted, and eventually, the upload temporary directory will be exploded.
-Springmvc模式下的代码样例：
+Sample code in Springmvc mode:
```java
@PostMapping(path = "/upload", consumes = MediaType.MULTIPART_FORM_DATA)
public String fileUpload(@RequestPart(name = "file1") MultipartFile file1, @RequestPart(name = "file2") Part file2, @RequestPart String param1) {
- ……
+ ......
}

+| servicecomb.uploads.maxSize | -1 | | The maximum allowable size of http body, the default value of -1 means unlimited |

-使用InputStream时，因为是流的方式，此时没有客户端文件名的概念，所以producer获取客户端文件名会得到null
+When using InputStream, because it is a stream, there is no concept of client file name at this time, so the producer will get the client file name will get null.
-如果既要使用内存数据，又想让producer可以获取客户端文件名，可以使用resource类型，继承org.springframework.core.io.ByteArrayResource，且override getFilename即可。
+If you want to use both memory data and the producer to get the client file name, you can use the resource type, inherit org.springframework.core.io.ByteArrayResource, and override getFilename.
