Question

我已经尝试了一段时间来生成HTTP请求，就像下面报告的那样没有运气，所以我试图从StackOverFlow中获取其他人的想法。

请求应包含一个多部分正文，即HTTP Content-type标头的值为“multipart / mixed”，附件类型为octet-stream和json主体，如下所示：

·内容类型为“application / json”的JSON对象;

·Content-type为“application / octet-stream”的二进制对象。

请参阅下面我当前的代码和我在服务器端获得的输出，我还附上了我应该生成的请求。对于附件，我尝试了FileBody和InputStreamBody，结果相同。

在服务器端，我构建了一个HttpEntity，它没有附件，只有下面报告的内容。

希望有人能够给我一个提示，因为这会变得势不可挡。

提前致谢，埃托。

 FileBody attacement = new FileBody(new File(url.getPath()));
 String requestBody = "{the json string}";

 HttpEntity entity = MultipartEntityBuilder 
                .create() 
                .addTextBody("jsonBody", requestBody, 
                                ContentType.create("application/json")) 
                .addPart("att", attacement).build(); 

HttpPost post = new HttpPost( 
                "http://localhost:10191/dummy/endpoint"); 
post.addHeader("Content-Type", "multipart/mixed"); 
post.setEntity(entity); 

HttpClient httpclient = HttpClientBuilder.create().build(); 

HttpResponse response = httpclient.execute(post);
