Android的多部分HTTP POST不发送文件的MIME类型 [英] Android Multipart HTTP Post does not send the File's MIME type
问题描述
试图弄清楚什么是错我的编码。我跟着从这里 博客文章。
Trying to figure what's wrong with my codings. I followed a blog post from here.
我设法得到codeS实际的文件上传到PHP的Web服务。然而,由于某种原因,虽然我已经明确设置的MIME类型的文件,PHP表明MIME是只是一个空字符串,因此拒绝。
I managed to get the codes to actually upload the file to a PHP web service. However, for some reason although I've set explicitly the MIME type for the file, PHP shows that the MIME is just a blank string and therefore rejected.
下面是我的编码:
public String SendPost(String fn, String bid, String caption, String uid, String APIKey, String postHash)
throws ParseException, ClientProtocolException, IOException {
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost(UrbURL);
Log.i("POSTFN", fn);
Log.i("POSTFN", bid);
Log.i("POSTFN", caption);
Log.i("POSTFN", uid);
Log.i("POSTFN", APIKey);
Log.i("POSTFN", postHash);
String postAuth = uid + postHash;
postAuth = md5(postAuth);
postAuth = postAuth.substring(0, 16);
//Log.i("POSTAUTH", postAuth);
MultipartEntity mp = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
/*File tempImg = new File(fn);
FileBody bin = new FileBody(tempImg, "image/jpg");*/
mp.addPart("business_photo", new FileBody(new File(fn), "image/jpg"));
//StringBody s = new StringBody(bid, "text/plain", Charset.forName( "UTF-8" ));
mp.addPart("business_id", new StringBody(bid, "text/plain", Charset.forName( "UTF-8" )));
//s = new StringBody(caption, "text/plain", Charset.forName( "UTF-8" ));
mp.addPart("photo_caption", new StringBody(caption, "text/plain", Charset.forName( "UTF-8" )));
//s = new StringBody(uid, "text/plain", Charset.forName( "UTF-8" ));
mp.addPart("user_id", new StringBody(uid, "text/plain", Charset.forName( "UTF-8" )));
//s = new StringBody(APIKey, "text/plain", Charset.forName( "UTF-8" ));
mp.addPart("apikey", new StringBody(APIKey, "text/plain", Charset.forName( "UTF-8" )));
//s = new StringBody(postAuth, "text/plain", Charset.forName( "UTF-8" ));
mp.addPart("auth", new StringBody(postAuth, "text/plain", Charset.forName( "UTF-8" )));
httppost.setEntity(mp);
String response = EntityUtils.toString( httpclient.execute( httppost ).getEntity(), "UTF-8" );
httpclient.getConnectionManager().shutdown();
return response;
}
非常感谢前:)
Many thanks before :)
推荐答案
我有同样的问题,只是固定它。
I had the same problem and just fixed it.
我发现,使用 HttpMultipartMode.BROWSER_COMPATIBLE
$ P $从我的要求下被设置pvented正确MIMETYPE,当使用 ByteArrayBody
的图像。我想这可能是你有同样的问题。
I found that using the HttpMultipartMode.BROWSER_COMPATIBLE
prevented the correct mimeType from being set in my request, when using a ByteArrayBody
for an image. I assume this is probably the same problem you are having.
当我改变了这一行:
MultipartEntity mp = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
到
MultipartEntity mp = new MultipartEntity();
那么MIME类型设置正确和服务的上传工作。
then the mime type was set correctly and the service upload worked.
我看到人们使用了 BROWSER_COMPATIBLE
解决另一个问题,但希望你不需要它。
I see that people used the BROWSER_COMPATIBLE
for solving another problem, but hopefully you don't need it.
