上传文件Android org.apache.http.entity.mime.MultipartEntity：错误的请求错误

以下代码给出错误的请求错误，代码中的任何解决方案或错误。上传文件Android org.apache.http.entity.mime.MultipartEntity：错误的请求错误

MultipartEntity entityPost = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 

entityPost.addPart("data_1", new StringBody(String.valueOf(feedbackId), Charset.forName("UTF-8")));   
entityPost.addPart("file_1", new FileBody(__file)); 

HttpPost httppost = new HttpPost("http://www.example.com/webservice.asmx/method"); 
httppost.setEntity(entityPost); 
httppost.setHeader("Content-Type", "multipart/form-data"); 

HttpResponse __response = HttpManager.httpClient().execute(httppost);

的WebService：

public String method() {  
    try { 
     System.Web.HttpContext postContext = System.Web.HttpContext.Current; 

     string data = postContext.Request.Form["data_1"].ToString(); 

     System.Web.HttpFileCollection files = postContext.Request.Files;   
     System.Web.HttpPostedFile = files[0]; 

     //etc etc 

    } catch (Exception ex) { 
     // 
    } 
}

错误：

org.apache.http.client.HttpResponseException: Bad Request

和哪里是Web服务代码？ –

错误的请求：400是客户端请求错误在它进入webservice之前发生异常。该web服务代码已经使用正常的html multipart/form-data进行了测试如果在webservice上有任何错误，它会给出500+错误 – sawbeanraz

正如萨蒂亚Komatineni，戴夫·麦克莱恩，赛义德Y.在书临的Android 3.0提到哈希米。外部库中加入：

共享IO：HTTP // commons.apache.org/IO/

Mime4j：HTTP // james.apache.org/mime4j/

HttpMime：http // hc.apache.org/downloads.cgi（HttpClient内部）

它可以正常工作，与之前创建的web服务相同。

File file = new File(filePath);  
InputStream is = new FileInputStream(file); 

HttpClient httpClient = new DefaultHttpClient(); 
HttpPost postRequest = new HttpPost("http://mysomewebserver.com/services/doSomething.do"); 


byte[] data = IOUtils.toByteArray(is); 

InputStreamBody isb = new InputStreamBody(new 
ByteArrayInputStream(data), "filename"); 
StringBody sb1 = new StringBody("some text goes here"); 
StringBody sb2 = new StringBody("some text goes here too"); 
MultipartEntity multipartContent = new MultipartEntity(); 
multipartContent.addPart("uploadedFile", isb); 
multipartContent.addPart("one", sb1); 
multipartContent.addPart("two", sb2); 

postRequest.setEntity(multipartContent); 
HttpResponse response =httpClient.execute(postRequest); 
response.getEntity().getContent().close();

但有警告说MultipartEntity被取消了。我对此不太确定。
