Android 使用 HttpPost MultiPartEntityBuilder 上传照片

Upload Photo using HttpPost MultiPartEntityBuilder

提问by Filip Luchianenco

I am trying to upload the taken photo to server. this is what i do:

我正在尝试将拍摄的照片上传到服务器。这就是我所做的：

public JSONObject makePostFileRequest(String url, String photoFile) {
    try {
        // photoFile = /path/tofile/pic.jpg
        DefaultHttpClient httpClient = GlobalData.httpClient;
        HttpPost httpPost = new HttpPost(url);

        File file = new File(photoFile);
        FileBody fileBody = new FileBody(file); // here is line 221

        MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();

        multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        multipartEntity.addPart("PhotoMessage", fileBody);

        httpPost.setEntity(multipartEntity.build());

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();

I get this error:

我收到此错误：

What am I doing wrong?

我究竟做错了什么？

InputStream inputStream;

Check that jar in Order and Export tab and run.

在 Order 和 Export 选项卡中检查该 jar 并运行。

There is my working solution for sending image with post, using apache http libraries (very important here is boundary add It won't work without it in my connection):

有我使用 apache http 库发送图像的工作解决方案（这里非常重要的是边界添加它在我的连接中没有它就无法工作）：

ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] imageBytes = baos.toByteArray();

HttpClient httpclient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(StaticData.AMBAJE_SERVER_URL + StaticData.AMBAJE_ADD_AMBAJ_TO_GROUP);

String boundary = "-------------" + System.currentTimeMillis();

httpPost.setHeader("Content-type", "multipart/form-data; boundary="+boundary);

ByteArrayBody bab = new ByteArrayBody(imageBytes, "pic.png");
StringBody sbOwner = new StringBody(StaticData.loggedUserId, ContentType.TEXT_PLAIN);
StringBody sbGroup = new StringBody("group", ContentType.TEXT_PLAIN);

HttpEntity entity = MultipartEntityBuilder.create()
                    .setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
                    .setBoundary(boundary)
                    .addPart("group", sbGroup)
                    .addPart("owner", sbOwner)
                    .addPart("image", bab)
                    .build();

httpPost.setEntity(entity);

try {
       HttpResponse response = httpclient.execute(httpPost);
       ...then reading response

Better you pass the path of image file. Below is my code which I used to upload image to server.

最好传递图像文件的路径。下面是我用来将图像上传到服务器的代码。

public class UploadProductDetails {


    public void uploadProductDetails(String filePath, String fileName)
    {

        InputStream inputStream;
        try
        {
            inputStream = new FileInputStream(new File(filePath));
            byte[] data;
            try
            {
                data = IOUtils.toByteArray(inputStream);

                HttpClient httpClient = new DefaultHttpClient();

                httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT,
                        System.getProperty("http.agent"));



                HttpPost httpPost = new HttpPost("http://ipaddress");


                InputStreamBody inputStreamBody = new InputStreamBody(new ByteArrayInputStream(data), "abc.png");
                MultipartEntity multipartEntity = new MultipartEntity();
                multipartEntity.addPart("file", inputStreamBody);


                httpPost.setEntity(multipartEntity);
                HttpResponse httpResponse = httpClient.execute(httpPost);

                // Handle response back from script.
                if(httpResponse != null) {
                    //Toast.makeText(getBaseContext(),  "Upload Completed. ", 2000).show();

                } else { // Error, no response.
                    //Toast.makeText(getBaseContext(),  "Server Error. ", 2000).show();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        }
    }

}

Note that using this code: new InputStreamBody(new ByteArrayInputStream(yourByteArray))might result in some problems, because it returns -1when calling getContentLength().

请注意，使用此代码：new InputStreamBody(new ByteArrayInputStream(yourByteArray))可能会导致一些问题，因为它-1在调用getContentLength().

Instead, use this: new ByteArrayBody(yourByteArray)

相反，使用这个： new ByteArrayBody(yourByteArray)
