如何使用的multipart / form-data的上传图片/ Android上的图像 [英] How use multipart/form-data upload picture/image on Android
问题描述
这是我的code。
我得到HTTP 400错误,有人可以帮我吗?
HttpClient的HttpClient的;
HttpPost httpPost;
HTT presponse响应;
HttpContext的localContext;
FileEntity TMP = NULL;
字符串RET = NULL;
HttpClient的=新DefaultHttpClient();
httpClient.getParams()的setParameter(ClientPNames.COOKIE_POLICY,CookiePolicy.RFC_2109)。
httpPost =新HttpPost(URL);
TMP =新FileEntity(数据,UTF-8);
httpPost.setEntity(TMP);
httpPost.setHeader(内容类型,多部分/表单数据);
httpPost.setHeader(access_token,facebook.getAccessToken());
httpPost.setHeader(源,data.getAbsolutePath());
httpPost.setHeader(信息,标题的照片);
localContext =新BasicHttpContext();
响应= httpClient.execute(httpPost,localContext);
bobince,由于这是我的新的ID,我会尽量把OAuth的,以我的连接头。
这是我的老code,我会尽快更新它。
私人无效uploadPicture()抛出ParseException的,IOException异常{
HttpClient的HttpClient的=新DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,HttpVersion.HTTP_1_1);
HttpPost httppost =新HttpPost(https://graph.facebook.com/me/photos);
档案文件=新的文件(sdpicturePath);
// DEBUG
Log.d(TSET,FILE ::+ file.exists()); // IT IS NOT NULL
Log.d(TEST,AT+ fbAccessToken); //我得到了一些访问令牌
MultipartEntity mpEntity =新MultipartEntity();
ContentBody cbFile =新FileBody(文件,图像/ PNG);
ContentBody cbMessage =新StringBody(TEST TSET);
ContentBody cbAccessToken =新StringBody(fbAccessToken);
mpEntity.addPart(access_token,cbAccessToken);
mpEntity.addPart(源,cbFile);
mpEntity.addPart(信息,cbMessage);
httppost.setEntity(mpEntity);
// DEBUG
的System.out.println(执行请求+ httppost.getRequestLine());
HTT presponse响应= httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
// DEBUG
的System.out.println(response.getStatusLine());
如果(resEntity!= NULL){
的System.out.println(EntityUtils.toString(resEntity));
如果} //结束
如果(resEntity!= NULL){
resEntity.consumeContent();
如果} //结束
httpclient.getConnectionManager().shutdown();
uploadPicture的} //结束()
setEntity
设置整个请求体的来源,所以这只会工作,如果数据
文件是一个已经连接codeD 的multipart / form-data的
块。
要创建的multipart / form-data的
克斯codeD的形式提交用作POST请求的身体,你需要一个MIME多恩codeR,一般 org.apache.http.entity.mime.MultipartEntity
。不幸的是,这是不是由Android的捆绑,所以如果你想要你就必须在一个新的 HttpClient的来自Apache拉。

This is my code.
I got Http 400 error, can someone help me?
HttpClient httpClient;
HttpPost httpPost;
HttpResponse response;
HttpContext localContext;
FileEntity tmp = null;
String ret = null;
httpClient = new DefaultHttpClient( );
httpClient.getParams().setParameter( ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109) ;
httpPost = new HttpPost(url);
tmp = new FileEntity( data,"UTF-8" );
httpPost.setEntity( tmp );
httpPost.setHeader( "Content-Type", "multipart/form-data" );
httpPost.setHeader( "access_token", facebook.getAccessToken( ) );
httpPost.setHeader( "source", data.getAbsolutePath( ) );
httpPost.setHeader( "message", "Caption for the photo" );
localContext = new BasicHttpContext( );
response = httpClient.execute( httpPost,localContext );
bobince, thanks this is my new id, I will try put OAuth to my connection header.
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( )
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.
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.
See this question for example code and this thread for background.
