以下代码给出错误请求错误，代码中的任何解决方案或错误。

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);

网络服务：

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

先感谢您

正如 Satya Komatineni、Dave MacLean、Sayed Y. Hashimi 在 Book Pro Android 3 中提到的那样。添加了外部库：

共享 IO：http//commons.apache.org/io/

Mime4j：http//james.apache.org/mime4j/

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

它适用于之前创建的相同 Web 服务。

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();

但是有警告说 MultipartEntity 已被弃用。我对此不太确定。
