这是我的旧代码,我会尽快更新。
And this is my old code, I will update it soon.
private void uploadPicture( ) throws ParseException, IOException {
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams( ).setParameter( CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1 );
HttpPost httppost = new HttpPost( "https://graph.facebook.com/me/photos" );
File file = new File( sdpicturePath );
// DEBUG
Log.d( "TSET", "FILE::" + file.exists( ) ); // IT IS NOT NULL
Log.d( "TEST", "AT:" + fbAccessToken ); // I GOT SOME ACCESS TOKEN
MultipartEntity mpEntity = new MultipartEntity( );
ContentBody cbFile = new FileBody( file, "image/png" );
ContentBody cbMessage = new StringBody( "TEST TSET" );
ContentBody cbAccessToken = new StringBody( fbAccessToken );
mpEntity.addPart( "access_token", cbAccessToken );
mpEntity.addPart( "source", cbFile );
mpEntity.addPart( "message", cbMessage );
httppost.setEntity( mpEntity );
// DEBUG
System.out.println( "executing request " + httppost.getRequestLine( ) );
HttpResponse response = httpclient.execute( httppost );
HttpEntity resEntity = response.getEntity( );
// DEBUG
System.out.println( response.getStatusLine( ) );
if (resEntity != null) {
System.out.println( EntityUtils.toString( resEntity ) );
} // end if
if (resEntity != null) {
resEntity.consumeContent( );
} // end if
httpclient.getConnectionManager( ).shutdown( );
} // end of uploadPicture( )
推荐答案
setEntity
设置整个请求正文的来源,因此只有在数据
编码 multipart / form-data
块。
setEntity
sets the source of the whole request body, so this would only work if the data
file was an already-encoded multipart/form-data
block.
创建一个 multipart / form-data
-ncoded表单提交用作POST请求正文,您将需要一个MIME多部分编码器,通常为 org.apache.http.entity.mime.MultipartEntity
。不幸的是,这不是由Android捆绑的,所以如果你想要它,你必须拉一个新的从Apache。
To create a multipart/form-data
-encoded form submission for use as a POST request body, you'll need a MIME multipart encoder, typically org.apache.http.entity.mime.MultipartEntity
. Unfortunately, this is not bundled by Android so if you want it you'll have to pull in a newer HttpClient from Apache.
