I want to make an Htttp Connection Here is my code
try
{
HttpClient client = new DefaultHttpClient();
HttpPost httpMethod = new HttpPost("http://www.google.co.in/");
String requestBody = "some text";
HttpMethod.setEntity(new StringEntity(requestBody));
HttpResponse response = client.execute(httpMethod);
textView.setText(response.getStatusLine().toString());
}
But i m unable to and get the "HTTP/1.0 405 Method not Allowed" error
I will be thankfull your help
It means that the requested URL does not accept the POST method. Try again with GET.
Perhaps you should try with a server that accepts POST requests. There's probably nothing wrong with your code, Google's front page just doesn't do POST.
One quick example of a server you could use I can think of is JSFiddle's echo feature. I'm sure they won't mind.

I am trying to fire an API in which I need to add two headers i.e token and deviceid. Below is my code to add header:
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(nameValuePairs[0].get(0).getValue().toString());
nameValuePairs[0].remove(0);
ResponseHandler<String> res = new BasicResponseHandler();
// set header
httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
httpPost.setHeader("deviceid", "358978060711939");
httpPost.setHeader("token", "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJHVUlEIjoiYjdlNjZiOWQtMjBjNy00MGI2LTliMzgtOTc3OGQ2OWIwM2E1IiwiRU5USVRZIjoiRUFCTSIsIlVOSVQiOiJVQk0yIiwiUk9MRU5BTUUiOiJTRUxGIiwiSUQiOiIwMDAyMzciLCJBTFRJRCI6IjMzMyIsIlVTRVJfTkFNRSI6IkFuaWwiLCJMT0dJTl9HVUlEX0tFWSI6ImU2NWM2YWEzLTZlNDItNDUyYS1hOGEwLWRlYzRhMGRiNTIxNyIsImlhdCI6MTQ1OTI0ODkyM30.m742d9xd6XlBBjZ3_ODWuoCEdWvSkhPAuNrDee1vi74");
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs[0]));
response = httpClient.execute(httpPost, res);
In Response I am getting: org.apache.http.client.HttpResponseException: Not Found
When I replace token with any alpha numeric value then I am getting response with error message. But when I passed actual token value which is mentioned above I am getting exception. Even I tried with addHeader function also but getting same issue. I am unable to understand how to resolve this error.
it's the handler which is causing the error. Don't use.
You should either write your own handler or call execute without a handler.
httpClient.execute(httpPost);//remove the handler
I hope this is helpful. ThankYou
Your token seems to be incorrect. Header set in HTTP protocols has their own restrictions. To check it, just try to send your trim token (ex 30 chars).
If it don't helped, you have incorrect another parameters. Anyway, i would give you advice, to use Retrofit.
I'm trying to PUT some XML to a server, but the gist of it is that no matter what I do, HttpPut simply won't put anything in the Http body. The server always comes back saying that the body is missing, and looking at it through Wireshark, nothing is there! Here's the code I'm using to set up and run the request:
HttpPut putRequest = new HttpPut(urlString]);
StringEntity stringEntity = new StringEntity(xmlString, HTTP.ISO_8859_1);
stringEntity.setContentType("text/xml");
putRequest.setEntity(stringEntity);
putRequest.addHeader("Host", formatUrlForHostHeader(broadsoftUrl));
putRequest.addHeader("Authorization", authorizationString);
putRequest.addHeader("Content-Type", "text/xml");
putRequest.addHeader("Accept", "text/xml");
response = httpClient.execute(putRequest);
I'm not sure what else to include here. I tried it on 4.2 and 4.0.3. This code is running in the doInBackground of an AsyncTask. The response code I get is a 409 Conflict, and the body is the server's application-specific message, telling me the body is missing. I confirmed that it's missing with Wireshark.
EDIT:
An interesting note is that I ran the same code standalone on my desktop, and it worked. So, is there something up with the Android versions of HttpClient, or the system? I tried a few different API levels, too, just to check.
Any thoughts?
Thanks!
Alright, so the solution was to just give up on HttpPut and all that, and use HttpURLConnection. Here's how we ended up doing it:
URL url = new URL(theUrl);
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty("Host", formatUrlForHostHeader(broadsoftUrl));
httpCon.setRequestProperty("Authorization", authorizationString);
httpCon.setRequestProperty("Content-Type", "text/xml; charset=ISO_8859_1");
httpCon.setRequestProperty("Accept", "text/xml");
httpCon.setDoInput(true);
httpCon.setDoOutput(true);
httpCon.setRequestMethod("PUT");
OutputStreamWriter out = new OutputStreamWriter(httpCon.getOutputStream(), "ISO_8859_1");
out.write(xmlData);
out.close();
if(httpCon.getErrorStream() == null) {
return "";
} else {
return "ERROR";
}
We didn't need to get the response from our PUT request, but you check if it failed by seeing if the error stream exists. If you wanted to get the response, you would do something like this:
StringWriter writer = new StringWriter();
IOUtils.copy(httpCon.getInputStream(), writer, encoding);
String responseString = writer.toString();
Of course, you would have to include Apache's IOTools in your app.
409 Conflict is usually an Edit Conflict error, usually associated with wikis, but it could be any type of conflict with the request.

What type of data are you trying to post and is it possible that the host has existing data that cannot be changed?
I am using the HttpPut to communicate with server in Android, the response code I am getting is 500.After talking with the server guy he said prepare the string like below and send.
{"key":"value","key":"value"}
now I am completely confused that where should i add this string in my request.
Please help me out .
I recently had to figure out a way to get my android app to communicate with a WCF service and update a particular record. At first this was really giving me a hard time figuring it out, mainly due to me not knowing enough about HTTP protocols, but I was able to create a PUT by using the following:
URL url = new URL("http://(...your service...).svc/(...your table name...)(...ID of record trying to update...)");
//--This code works for updating a record from the feed--
HttpPut httpPut = new HttpPut(url.toString());
JSONStringer json = new JSONStringer()
.object()
.key("your tables column name...").value("...updated value...")
.endObject();
StringEntity entity = new StringEntity(json.toString());
entity.setContentType("application/json;charset=UTF-8");//text/plain;charset=UTF-8
entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
httpPut.setEntity(entity);
// Send request to WCF service
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(httpPut);
HttpEntity entity1 = response.getEntity();
if(entity1 != null&&(response.getStatusLine().getStatusCode()==201||response.getStatusLine().getStatusCode()==200))
{
//--just so that you can view the response, this is optional--
int sc = response.getStatusLine().getStatusCode();
String sl = response.getStatusLine().getReasonPhrase();
}
else
{
int sc = response.getStatusLine().getStatusCode();
String sl = response.getStatusLine().getReasonPhrase();
}
With this being said there is an easier option by using a library that will generate the update methods for you to allow for you to update a record without having to manually write the code like I did above. The 2 libraries that seem to be common are odata4j and restlet. Although I haven't been able to find a clear easy tutorial for odata4j there is one for restlet that is really nice: http://weblogs.asp.net/uruit/archive/2011/09/13/accessing-odata-from-android-using-restlet.aspx?CommentPosted=true#commentmessage
Error 500 is Internal Server error. Not sure if this answers your question but I personally encountered it when trying to send a data URI for an animated gif in a PUT request formatted in JSON but the data URI was too long. You may be sending too much information at once.
I need to send a byte arrray file using WCF rest services. I have to send the data using HttpPost method in android. The code which i am using give the status as HTTP/1.1 400 Bad Request error.
private final static String URI = "http://192.168.1.15/QueryService/Import/Test";
final HttpPost request = new HttpPost(URI);
final HttpClient httpClient = new DefaultHttpClient();
final ByteArrayEntity entity = new ByteArrayEntity(fileToBytes(pathToOurFile));
entity.setContentType("application/octet-stream");
entity.setChunked(true);
request.setEntity(entity);
final HttpResponse hr = httpClient.execute(request);
final StatusLine status = hr.getStatusLine();
httpClient.getConnectionManager().shutdown();
It is difficult to tell what is wrong with your request. The standard way of resolving this kind of errors is:
Create a WCF client for your service. Verify that it works as expected.
Use Fiddler or another suitable tool to intercept the HTTP request your client is generating. Both the headers and the body are important.
Modify your Android request to generate the exact same request as the WCF client.
I was also facing same problem with WCF service. 400 Bad request means request parameter value which you are passing to method doesn't match with method's parameter. I have used Base64 string encoding to pass file as method parameter. May it'll help you.
I want to access a Restful web service. I want the request should be in the following format.
GET /API/Contacts/username HTTP/1.1
HOST: $baseuri:port
Accept: text/xml
Authorization: Basic ZmF0aWdhYmxlIGdlbmVyYXR=
And also I am calling the web service though HTTPS protocol.
The folowing is the code I am using :
HttpGet get = new HttpGet("https://secure.myapp.com/MyApp/API/Contacts/myname");
get.addHeader("Accept","text/xml");
get.addHeader("Authorization","Basic ZmF0aWdhYmxlIGdlbmVyYXR=");
get.addHeader("Host","https://secure.myapp.com");
get.addHeader("Connection Use","HTTP 1.1");
DefaultHttpClient client = new DefaultHttpClient();
ResponseHandler objHandler = new BasicResponseHandler();
String getResponse = client.execute(get,objHandler);
But I am getting an Error : 400 Bad request.
I am not sure whether my code is correct. Is it necessary to specify the method (GET, POST or PUT) explicitly in the header?
Please help me...
Thnking You....
Shouldn't you put 'Basic ZmF0aWdhYmxlIGdlbmVyYXR=' in double quotes?
Also check web service example request and response and make sure that everything is specified.
Ohh...
That was my mistake.
I did not keep the order of adding headers.
When I changed its order according to the Request it is working fine.
In the request the HOST should be the first parameter.
The following is the corrected code.
get.addHeader("Host","secure.myapp.com");
get.addHeader("Accept","text/xml");
get.addHeader("Authorization","Basic ZmF0aWdhYmxlIGdlbmVyYXR=");
get.addHeader("Connection Use","HTTP 1.1");
Sorry to disturb you all...
