Upload Photo using HttpPost MultiPartEntityBuilder

问题:

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

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:

11-29 13:12:14.924: E/AndroidRuntime(15781): Caused by: java.lang.NoClassDefFoundError: org.apache.http.entity.ContentType 11-29 13:12:14.924: E/AndroidRuntime(15781): at org.apache.http.entity.mime.content.FileBody.(FileBody.java:89) 11-29 13:12:14.924: E/AndroidRuntime(15781): at com.petcial.petopen.custom.JSONParser.makePostFileRequest(JSONParser.java:221)

What am I doing wrong?

Update

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

httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT,
                        System.getProperty("http.agent"));
InputStreamBody inputStreamBody = new InputStreamBody(new ByteArrayInputStream(data), "Pic.jpg");

MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();

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

httpPost.setEntity(multipartEntity.build());

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

here is the error:

these libraries solved my issue:

Check that jar in Order and Export tab and run.

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):

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.

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 -1 when calling getContentLength().

Instead, use this: new ByteArrayBody(yourByteArray)
