什么外部JAR做我需要做一个Android多部分POST? [英] What external JARS do I need to do an Android Multipart POST?
问题描述
我试图做一个Android的多部分POST,使用下面的code
I am trying to do a Android Multipart POST, using the following code
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(urlString);
File file = new File(pic);
Log.d(TAG, "UPLOAD: setting up multipart entity");
MultipartEntity mpEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
Log.d(TAG, "UPLOAD: file length = " + file.length());
Log.d(TAG, "UPLOAD: file exist = " + file.exists());
try {
mpEntity.addPart("datafile", new FileBody(file, "application/octet"));
mpEntity.addPart("id", new StringBody("1"));
} catch (UnsupportedEncodingException e1) {
Log.d(TAG, "UPLOAD: UnsupportedEncodingException");
e1.printStackTrace();
}
httppost.setEntity(mpEntity);
Log.d(TAG, "UPLOAD: executing request: " + httppost.getRequestLine());
Log.d(TAG, "UPLOAD: request: " + httppost.getEntity().getContentType().toString());
HttpResponse response;
try {
Log.d(TAG, "UPLOAD: about to execute");
response = httpclient.execute(httppost);
Log.d(TAG, "UPLOAD: executed");
HttpEntity resEntity = response.getEntity();
Log.d(TAG, "UPLOAD: respose code: " + response.getStatusLine().toString());
if (resEntity != null) {
Log.d(TAG, "UPLOAD: " + EntityUtils.toString(resEntity));
}
if (resEntity != null) {
resEntity.consumeContent();
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
这在
MultipartEntity mpEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
我想这是跟我使用的是外部JAR。我在我的项目中的libs文件夹中,我已经提到我的项目构建路径下的文件。
My guess this is to do with the external Jars I am using. I have a Libs folder in my project and I have referenced the following files in my project build path.
HttpClient的-4.2.jar,的HttpCore-4.2.jar和httpmime-4.2.jar
httpclient-4.2.jar, httpcore-4.2.jar and httpmime-4.2.jar
这些是正确的版本?或者我需要更多的JARS?
Are these the correct versions? Or do I need more JARS ?
推荐答案
在你的Android项目,创建一个名为库在项目的根目录下(旁的src /,RES /等。)
In your Android project, create a directory named libs at the root of your project (next to src/, res/, etc.)
找到的JAR文件要使用,并将其复制到库/目录下的库。
Locate the JAR file for the library you want to use and copy it into the libs/ directory.
