上传base64编码图像从Android WCF服务 [英] Upload base64 encoding Image to WCF service from android

问题描述

我有一个Android程序，可以上传图片到WCF服务。 WCF服务与接受映像名称，文件夹名称和图像的base64编码的JSON对象。

I have an Android program that can upload an image to a WCF service. The WCF service accepts a JSON object with image name, folder name and a base64 encoding of the image.

我用小提琴手从在线服务测试该服务，我带codeD图像并把它放在对象。然后由POST请求;然后WCF服务上传成功的形象。

I use fiddler for testing that service, I encoded the image from an online service and put it in object. Then composed a POST request ; and then WCF service successfully uploaded image.

但是，当我使用Android的HTTP客户端，做WCF接受请求同样的事情，但我不认识的形象。

But when I use Android HTTP client and doing same thing WCF accepts the request, but I don't recognize the image.

这是我的Andr​​oid code：

Here is my Android code:

try {
    HttpPost httpPost=new HttpPost(this.remoteBasePath);
    JSONObject obj = new JSONObject();
    obj.put(FILE_NAME, fileName);
    obj.put(FILE_STREAM,fileStream);
    obj.put(FOLDER_NAME, remoteFolder);
    httpPost.setHeader("Content-type", "application/json; charset=utf-8");
    httpPost.setEntity(new StringEntity(obj.toString()));
    httpPost.setHeader(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
    httpResponse=httpClient.execute(httpPost);
    if(httpResponse!=null){
        TLLog.d(TAG,"StatusCode : "+ httpResponse.getStatusLine().getStatusCode());
        if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {                               
            InputStream instream = httpResponse.getEntity().getContent();
            BufferedReader r = new BufferedReader(
            new InputStreamReader(instream));
            StringBuilder total = new StringBuilder();
            String line;
            while ((line = r.readLine()) != null) {
                total.append(line);
            }
            instream.close();
            String result = total.toString();
            TLLog.d(TAG,"Image posting result : "+ result);
            return true;
        }
    }
} catch (ClientProtocolException e) {
    TLLog.e(TAG, e.getStackTrace().toString());
} catch (IOException e) {
    TLLog.e(TAG, e.getStackTrace().toString());
} catch (JSONException e) {
    e.printStackTrace();
}

我不明白的问题。

I can't understand problem.

推荐答案

大家好我终于想通了问题。
问题是编码，所以我使用类 Base64.java ，我从互联网上下载。我用下面的方法encording

Hi guys finally i figured out problem. Problem is encoding so I use class Base64.java that I downloaded from internet. I use following method for encording

public static String encodeTobase64(Bitmap image) throws IOException
{
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();  
    image.compress(Bitmap.CompressFormat.JPEG, 50, outputStream);
    byte[] bs = outputStream.toByteArray();
    String imageEncoded=Base64.encodeBytes(bs);
    return imageEncoded;
}

和使用返回值作为文件流。所以我的问题就解决了​​。

and use returned value as file stream. So my problem is solved.
