问题描述

我想上传拍摄的照片到服务器。这是我做的：

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();

我得到这个错误：

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.<init>(FileBody.java:89)
11-29 13:12:14.924: E/AndroidRuntime(15781):    at com.petcial.petopen.custom.JSONParser.makePostFileRequest(JSONParser.java:221)

我是什么做错了吗？

What am I doing wrong?

更新

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();

下面是错误：

11-29 14:00:33.364: E/AndroidRuntime(19478): Caused by: java.lang.NoClassDefFoundError: org.apache.http.util.Args
11-29 14:00:33.364: E/AndroidRuntime(19478):    at org.apache.http.entity.mime.content.AbstractContentBody.<init>(AbstractContentBody.java:48)
11-29 14:00:33.364: E/AndroidRuntime(19478):    at org.apache.http.entity.mime.content.InputStreamBody.<init>(InputStreamBody.java:69)
