AngularJS +弹簧：415不支持的媒体类型 [英] AngularJS + Spring: 415 unsupported media type

问题描述

HTTP POST越来越错误上载多部分数据

http post is getting error while uploading multipart data

var formData = new FormData();

formData.append("startDate",$("#startDate").val());
formData.append("File1",$("input[name='file']")[0].files[0]);
formData.append("File2",$("input[name='file2']")[0].files[0]);

$http.post("sampleurl",formData,
{ headers : 'Content-Type' : undefined},
transformRequest : angular.identity
}).then(function(data){
  alert(data);
    });
}

我的服务器端code是

my server side code is

@RequestMapping(value = "sampleurl", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON)
    public @ResponseBody
    Response createSomething(
            @RequestBody Request request,
            HttpServletRequest httpServletRequest,
            HttpServletResponse httpServletResponse) {
            // code here
    }

推荐答案

HTTP错误415意味着，请求内容是不是在适当的格式。

An http error 415 means that content of request is not in the appropriate format.

Spring MVC的'@RequestBody期待一个JSON体（有内容类型等于'应用程序/ JSON'）和你的内容类型明确设置为undefined。

Spring MVC '@RequestBody' expect a json body (with a Content-Type equal to 'application/json') and you explicitly set your Content-Type to undefined.

解决的办法是设置内容类型为应用程序/ JSON在您的文章的请求或删除@RequestBody注释。

The solution is to set your content-type to 'application/json' in your post request or to remove @RequestBody annotation.

看来你尝试上传文件时，更容易将删除@RequestBody注释。

It seems that you try to upload files, the easier would be to remove @RequestBody annotation.
