安卓：发送通过张贴图片 [英] Android: Sending an image through POST

问题描述

我一直在寻找周围的解决方案，以及所遇到的多部分和不同的设置，但我似乎无法得到它的正常工作。

下面是我到目前为止所。

编辑：服务器端错误我得到一个500。我认为，这是因为我送的数据是太大了，一个请求或者是格式不正确

。

  ByteArrayOutputStream宝=新ByteArrayOutputStream（）;

                    bm.com preSS（Bitmap.Com pressFormat.JPEG，90，宝）;

                    byte []的BA = bao.toByteArray（）;

                    字符串BA1 = Base64.en codeToString（BA，Base64.URL_SAFE）;

                    mParams.add（新BasicNameValuePair（故事[图]BA1））;

    HttpClient的HttpClient的=新DefaultHttpClient（）;
    HttpPost httppost =新HttpPost（的mpath）;
    //添加数据
    尝试
    {
        httppost.setHeader（授权，Base64.en codeToString（新的StringBuilder（SSSSS）.append（：）追加（SSSSSS）的ToString（）的GetBytes（UTF-8），Base64.URL_SAFE | Base64.NO_WRAP））;
        httppost.setEntity（新UrlEn codedFormEntity（mParams））;
        HTT presponse RH = httpclient.execute（httppost）;
        Log.v（TAG的回应：+ rH.toString（））;
        INT F = 0;
    }
    赶上（Htt的presponseException E）
    {
        Log.e（TAG，e.getLocalizedMessage（））;
        Log.e（TAG，e.getMessage（））;
        e.printStackTrace（）;
    }
 

解决方案

这是我昨天做了，也许这将有助于

 位图bitmapOrg = images.get（0）;

        ByteArrayOutputStream宝=新ByteArrayOutputStream（）;

        字符串UPLOAD_URL = prepare_upload_url（）;
        bitmapOrg.com preSS（Bitmap.Com pressFormat.JPEG，90，宝）;

        byte []的数据= bao.toByteArray（）;

        HttpClient的HttpClient的=新DefaultHttpClient（）;
        HttpPost postRequest =新HttpPost（UPLOAD_URL）;
        MultipartEntity实体=新MultipartEntity（
                HttpMultipartMode.BROWSER_COMPATIBLE）;

        //设置数据和图像内容类型头
        entity.addPart（文件，
                新ByteArrayBody（数据，图像/ JPEG，文件））;
        postRequest.setEntity（实体）;
        尝试 {

            HTT presponse响应= httpClient.execute（postRequest）;
        //读取响应
            串jsonString = EntityUtils.toString（response.getEntity（））;
            Log.v（ProgramConstants.TAG，上传文件后，
                    + jsonString）;

        }赶上（ClientProtocolException E）{
            // TODO自动生成的catch块
            e.printStackTrace（）;
        }赶上（IOException异常E）{
            // TODO自动生成的catch块
            e.printStackTrace（）;
        }
 

I've been searching around for the solution, and have come across the multipart and different setups, but I can't seem to get it working correctly.

Here's what I have so far.

Edit: The server side error I'm getting is a 500. I assume that's because the data I'm sending is either too big for one request or is in an incorrect format.

                    ByteArrayOutputStream bao = new ByteArrayOutputStream();

                    bm.compress(Bitmap.CompressFormat.JPEG, 90, bao);

                    byte [] ba = bao.toByteArray();

                    String ba1=Base64.encodeToString(ba,Base64.URL_SAFE);

                    mParams.add(new BasicNameValuePair("story[image]",ba1));

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(mPath);
    // Add your data
    try
    {
        httppost.setHeader("Authorization", Base64.encodeToString(new StringBuilder(sssss).append(":").append(ssssss).toString().getBytes("UTF-8"), Base64.URL_SAFE|Base64.NO_WRAP));
        httppost.setEntity(new UrlEncodedFormEntity(mParams));
        HttpResponse rH = httpclient.execute(httppost);
        Log.v(TAG, "response: " + rH.toString());
        int f = 0;
    }
    catch(HttpResponseException e)
    {
        Log.e(TAG, e.getLocalizedMessage());
        Log.e(TAG, e.getMessage());
        e.printStackTrace();
    }

解决方案

This is what I did yesterday, maybe it will help

        Bitmap bitmapOrg = images.get(0);

        ByteArrayOutputStream bao = new ByteArrayOutputStream();

        String upload_url = prepare_upload_url();
        bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);

        byte[] data = bao.toByteArray();

        HttpClient httpClient = new DefaultHttpClient();
        HttpPost postRequest = new HttpPost(upload_url);
        MultipartEntity entity = new MultipartEntity(
                HttpMultipartMode.BROWSER_COMPATIBLE);

        //Set Data and Content-type header for the image
        entity.addPart("file",
                new ByteArrayBody(data, "image/jpeg", "file"));
        postRequest.setEntity(entity);
        try {

            HttpResponse response = httpClient.execute(postRequest);
        //Read the response
            String jsonString = EntityUtils.toString(response.getEntity());
            Log.v(ProgramConstants.TAG, "after uploading file "
                    + jsonString);

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
