Question

我正在尝试使用此代码在服务器上上传图像和文本，但是使用此代码我遇到了一些错误“内容长度标题已经存在”或者如果我没有设置内容lenget那么它返回“> 411长度“

请给我一些解决方案

这是我的代码

    String url = webserviceURLs.createQuestion+"?token"+OkayUserProfileProps.tocken; 
    try { 
        HttpClient httpclient = new DefaultHttpClient(); 
        HttpPost httppost = new HttpPost(url); 
        httppost.setHeader("Content-Type", "multipart/form-data");
        httppost.addHeader("Accept", "application/json");
        byte[] abc = convertImageToByte(Uri.parse(imageName.get(0)));

        InputStream in = new ByteArrayInputStream(abc);
        ContentBody mimePart = new InputStreamBody(in, "file1"); 
        MultipartEntity reqEntity = new MultipartEntity();

        reqEntity.addPart("userquestion[question_id]", new StringBody("2")); 
        reqEntity.addPart("userquestion[looks][0][photo]", mimePart);
        httppost.setEntity(reqEntity);   

        int a=abc.length;
        httppost.setHeader(HTTP.CONTENT_LEN,""+abc.length);

        HttpResponse response = httpclient.execute(httppost); 
        HttpEntity resEntity = response.getEntity(); 


        if (resEntity != null) {       
            String retSrc = EntityUtils.toString(resEntity);
            System.out.println("Responce "+retSrc);

        }



        return null;
    } catch (Exception e) { 
        // TODO Auto-generated catch block
        Log.e("Exception", e.getMessage() + ""); 
        return null;
    }

试试这个，

MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("image", new FileBody(new File("your image path"));

如何为多部分httppost设置标题？
