I got an error using HttpPost for sending an MMS in Android.
In the Logcat it says:
ERROR/Here(447): ---------Error-----Target host must not be null, or set in parameters.
My sample code:
String url = "myurl";
HttpClient httpClient = new DefaultHttpClient();
try {
httpClient.getParams().setParameter(url, new Integer(90000)); // 90 second
HttpPost post = new HttpPost(url);
File SDCard = Environment.getExternalStorageDirectory();
File file = new File(SDCard, "1.png");
FileEntity entity;
entity = new FileEntity(file,"binary/octet-stream");
entity.setChunked(true);
post.setEntity(entity);
post.addHeader("Header", "UniqueName");
Log.i("MMSHTTP","----post---------------"+post);
HttpResponse response = httpClient.execute(post);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e("Here",
"--------Error--------Response Status line code:" + response.getStatusLine());
}
else
{
// Here every thing is fine.
}
HttpEntity resEntity = response.getEntity();
if (resEntity == null) {
Log.e("Here","---------Error No Response!!-----");
}
} catch (Exception ex) {
Log.e("Here","---------Error-----"+ex.getMessage());
ex.printStackTrace();
} finally {
httpClient.getConnectionManager().shutdown();
}
How do I fix the error?
The url you're specifying is in your sample code is:
String url = "myurl";
In order for HttpClient to be able to determine the host name, you're going to need to supply a valid url. Something along the lines of:
String url = "http://myurl.com/index";
Note: The 'http://' is important so that the appropriate protocol can be determined.
This guy had the same problem.

I am trying to do a GET request using the foursquare checkin endpoint. I'm getting back a 404 error which is endpoint not found. Any help with why that could be happening would be great!
try {
URI url = new URI("https://api.foursquare.com/v2/user/self/checkins?oauth_token="+TokenStore.get().getToken()+"&v=20140219");
HttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response = httpclient.execute(request);
HttpEntity entity = response.getEntity();
is = entity.getContent();
int responceCode = response.getStatusLine().getStatusCode();
Log.i(TAG, "Responce = "+ responceCode);
} catch(Exception e) {
e.printStackTrace();
}
The endpoint is users/self, not user/self, which you have. Just a typo :)
I have a method to connect to send post data to a webservice and get the response back as follow:
public HttpResponse sendXMLToURL(String url, String xml, String httpClientInstanceName) throws IOException {
HttpResponse response = null;
AndroidHttpClient httpClient = AndroidHttpClient.newInstance(httpClientInstanceName);
HttpPost post = new HttpPost(url);
StringEntity str = new StringEntity(xml);
str.setContentType("text/xml");
post.setEntity(str);
response = httpClient.execute(post);
if (post != null){
post.abort();
}
if (httpClient !=null){
httpClient.close();
}
return response;
}
Then, in my AsyncTask of my fragment, I try to read the response using getEntity():
HttpResponse response = xmlUtil.sendXMLToURL("url", dataXML, "getList");
//Check if the request was sent successfully
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
// Parse result to check success
responseText = EntityUtils.toString(response.getEntity());
if (!xmlParser.checkForSuccess(responseText, getActivity())){
//If webservice response is error
///TODO: Error management
return false;
}
}
And when I reach that line:
responseText = EntityUtils.toString(response.getEntity());
I get an exception: java.net.SocketException: Socket closed.
This behavior doesn't happen all the time, maybe every other time.
Just write
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(your url);
HttpResponse response = client.execute(post);
it should work.No need to write codes which makes confusion.
I also experienced the 'socket closed' exception when using a client instance built using HttpClientBuilder. In my case, I was calling HttpRequestBase.releaseConnection() on my request object within a finally block before processing the response object (in a parent method). Flipping things around solved the issue... (working code below)
try {
HttpResponse response = httpClient.execute(request);
String responseBody = EntityUtils.toString(response.getEntity());
// Do something interesting with responseBody
} catch (IOException e) {
// Ah nuts...
} finally {
// release any connection resources used by the method
request.releaseConnection();
}
First, thanks for you reading.
Here is my code
public void uploadPicture(String token, String message, File imageFile) 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");
MultipartEntity mpEntity = new MultipartEntity();
mpEntity.addPart(Facebook.TOKEN, new StringBody(token));
mpEntity.addPart("source", new FileBody(imageFile, "image/png"));
mpEntity.addPart("message", new StringBody(message));
httppost.setEntity(mpEntity);
// DEBUG
Log.v(CLASS_NAME, "executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
// DEBUG
Log.v(CLASS_NAME, "getStatusLine " + response.getStatusLine());
if (resEntity != null) {
Log.v(CLASS_NAME, EntityUtils.toString(resEntity));
} // end if
if (resEntity != null) {
resEntity.consumeContent();
} // end if
httpclient.getConnectionManager().shutdown();
}
DDMS show the response:
executing request POST https://graph.facebook.com/me/photos HTTP/1.1
getStatusLine HTTP/1.1 200 OK
{"id":"113353398770816″}
so, it should complete finished. but nothing change in my facebook.
can anyone tell me what i did wrong?
thank you again.
Probably you have to wait a little. I've seen that uploaded picture appeared after some time.
I have some code to post an image to my php script that uploads to a database, when it adds to the database the file type is application/oct???? (what is this)
is there anyway of changing this to a jpg file at the android stage?
Below is my code
HttpClient client = new DefaultHttpClient();
String postURL = "http://10.0.2.2:90/mobileupload3.php";
HttpPost post = new HttpPost(postURL);
FileBody bin = new FileBody(file);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("image", bin);
reqEntity.addPart("name", new StringBody(enteredName));
reqEntity.addPart("gender", new StringBody(radio));
reqEntity.addPart("cat", new StringBody(radio2));
reqEntity.addPart("lat", new StringBody(lat));
reqEntity.addPart("lon", new StringBody(lon));
post.setEntity(reqEntity);
HttpResponse response = client.execute(post);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
Log.i("RESPONSE",EntityUtils.toString(resEntity));
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
application/oct (I assume you mean application/octet-stream) is a MIME type for a general binary file.
Without more information on your method of upload, I believe that the other part of your question has already been answered on SO here.
I've been looking into this for the last day or two and can not seem to find a solution to my issue. I am trying to post an image to a server using httppost.
I have tried two ways of doing this and both complete the post but with no content i.e. the content length is 0.
The first is as follows:
String url = "MYURL";
HttpClient httpClient = new DefaultHttpClient();
try {
httpClient.getParams().setParameter("http.socket.timeout", new Integer(90000)); // 90 second
HttpPost post = new HttpPost(url);
File SDCardRoot = Environment.getExternalStorageDirectory();
File file = new File(SDCardRoot,"/DCIM/100MSDCF/DSC00004.jpg");
FileEntity entity;
entity = new FileEntity(file,"binary/octet-stream");
entity.setChunked(true);
post.setEntity(entity);
post.addHeader("Header", "UniqueName");
HttpResponse response = httpClient.execute(post);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e("Here","--------Error--------Response Status line code:"+response.getStatusLine());
}else {
// Here every thing is fine.
}
HttpEntity resEntity = response.getEntity();
if (resEntity == null) {
Log.e("Here","---------Error No Response!!-----");
}
} catch (Exception ex) {
Log.e("Here","---------Error-----"+ex.getMessage());
ex.printStackTrace();
} finally {
httpClient.getConnectionManager().shutdown();
}
and the second is:
String url = "MYURL";
//File SDCardRoot = Environment.getExternalStorageDirectory();
File file = new File(Environment.getExternalStorageDirectory(),"/DCIM/100MSDCF/DSC00004.jpg");
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true);
// Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
Log.d("finishing", "The try catch function");
} catch (Exception e) {
// show error
}*/
As you can see I have hardcoded a path to a specific image, this is to be dynamic when I get it up and running.
Can anyone see what i'm doing wrong? Am I leaving out something? I know I use setChunked and setContenttype - is there a setContent option?
Any help would be grately appreciated.
Thanks,
jr83.
You can use upload your image by sending multipart messages; you might find this discussion useful.
