413请求实体太大

413 Request entity too large

我上传的js代码是:

 $scope.upload = function(files) {
    if (!files || !files.length) {
    } else {
      for (var i = 0; i < files.length; i++) {
        var file = files[i];
        Upload.upload({
            url: '/uploadFile',
            file: file
        }).
        }).success(function (data, status, headers, config) {
        }).error(function (data, status, headers, config) {
            $scope.showServerError(status, data);
        })
      }
    }
  };

服务器中的

是:

in the server is :

def uploadFile = Action(parse.multipartFormData) { implicit request =>

    request.body.file("file").fold {
      BadRequest("Missing file")
    } { uploadedFile => {

      val localFile = new File("/tmp/" + uploadedFile.ref.file.getName)

      Files.copy(uploadedFile.ref.file.toPath, localFile.toPath, StandardCopyOption.REPLACE_EXISTING)
      localFile.deleteOnExit()
      val j = Json.parse( ${Crypto.encryptAES(localFile.getAbsolutePath)}})
      Ok(j)
    }}
  }

为了支持更大的文件，需要进行哪些更改?

推荐答案

您可以使用

You can use the maxLength body parser to specify the maximum size of the body in bytes:

// Allow up to 15MB files...
private val uploadParser = parse.maxLength(15*1024*1024, parse.multipartFormData)

def uploadFile = Action(uploadParser) { implicit request =>
  ...
}

多部分表单数据的默认值为10MB，您也可以通过更改play.http.parser.maxDiskBuffer设置来覆盖它.请参见文档.

The default is 10MB for multipart form data, which you can also override by changing the play.http.parser.maxDiskBuffer setting. See the docs.
