Question

我正在尝试使用HttpClient multipart / form-data创建附件，但不断获取400：Bad请求状态代码作为输出。我在做什么错了。

引荐Apache HttpClient making multipart form post的要求如下：

         HttpPost httppost = new HttpPost(URL);
         httppost.addHeader("Content-Type", "multipart/form-data");
         HttpEntity entity = MultipartEntityBuilder.create()
        .addTextBody(name,"{ \"fileName\": \"abc.txt\", 
        \"description\": {  \"raw\": \"Test\"  }}" , 
        ContentType.create("application/json"))
        .addTextBody("file",fileBody_in_bytes,
        ContentType.create("text/plain"))
        .build();
        System.out.print(entity);
        httppost.setEntity(entity);
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity result = response.getEntity();
        httppost.setEntity(result);




But got this error:

{"_type":"Error","errorIdentifier":"urn:openproject-org:api:v3:errors:InvalidRequestBody","message":"The request body did not contain the expected multipart parts."}

API中提供的格式如下：

**Header**

Content-Type: multipart/form-data


**Body**

--boundary-delimiter
Content-Disposition: form-data; name="metadata"
Content-Type: application/json; charset=UTF-8

{
  "fileName": "cute-cat.png",
  "description": {
    "raw": "A cute kitty, cuddling with its friends!"
  }
}

--boundary-delimiter
Content-Disposition: form-data; name="file"; filename="attachment"
Content-Type: image/png

PNG file data
--boundary-delimiter--

Documentation of API

谁能看到我的错误？
