问题
I am creating a new user through android app programatically using amazon web-service. here is my code(asynctask):
private class S3RegisterNewUser extends AsyncTask<String, Void, String> {
ProgressDialog dialog;
String email;
public S3RegisterNewUser(String email) {
// TODO Auto-generated constructor stub
this.email=email;
}
protected void onPreExecute() {
dialog = new ProgressDialog(S3UploaderActivity.this);
dialog.setMessage(S3UploaderActivity.this
.getString(R.string.plswait));
dialog.setCancelable(false);
dialog.show();
}
protected String doInBackground(String ...strings) {
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(Constants.REGISTER); //url[0]
String result = "";
boolean result_recvd = false;
boolean ifallset = false;
// sparser = new ParsingClass();
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("UserName",email));
nameValuePairs.add(new BasicNameValuePair("Path","/"));
nameValuePairs.add(new BasicNameValuePair("Version","2010-05-08"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
/*HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
bindDataToListing(is);*/
HttpResponse resp = httpclient.execute(httppost);
HttpEntity ent = resp.getEntity();
ist = ent.getContent();
result = getStringFromInputStream(ist);
if(!result.contains("result")) {
Toast.makeText(S3UploaderActivity.this, "No connection or data not received from server", Toast.LENGTH_SHORT).show();
//result = "<?xml version=\"1.0\" encoding=\"utf-8\"?><xml><result>0</result><message>"+Constants.noConnection+"</message></xml>";
result_recvd = false;
}else{
/** Result has been received from server which contains atleast the 'result' TAG
* This helps us to know if data is being fetched from server or not.*/
result_recvd = true;
}
// ifallset = bindDataToListing(result, result_recvd);
if(!result.contains("result")){
Toast.makeText(S3UploaderActivity.this, "No connection or data not received from server", Toast.LENGTH_SHORT).show();
}
//result = convertStreamtoString(is);
Log.e("-- parseResultXML: ", ""+result);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} catch (AmazonClientException ace) {
System.out.println("Caught an AmazonClientException, " +
"which means the client encountered " +
"an internal error while trying to communicate" +
" with S3, " +
"such as not being able to access the network.");
System.out.println("Error Message: " + ace.getMessage());
}
return null;
}
protected void onPostExecute(String file_url) {
dialog.dismiss();
}
}
/** Convert input stream to a String
* @param is -Supply the input stream variable here */
private String getStringFromInputStream(InputStream is) {
StringBuilder sb = new StringBuilder();
String line;
try {
br = new BufferedReader(new InputStreamReader(is));
while ((line = br.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (br != null ) {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return sb.toString();
}
Constants.REGISTER="https://iam.amazonaws.com/"
I am following the Iam documentation.But instead of recieving xml result according to the documentation I am recieving HTML responses like below:

If I am doing something wrong or sending some wrong parameters then the code must throw an exception or stop.But why it is returning this HTML file??What wrong I am doing here??

Update
The AWS SDK for Android seems to be a bit lacking on the getting started front indeed - it seems to be designed fairly similar to the AWS SDK for Java though (naturally):
There, every AWS service has its own service specific client, which would be AmazonIdentityManagementClient for your use case. Given it is absent, it seems the AWS SDK for Android doesn't support IAM directly, so you'd need to resort to the IAM Query API indeed (as mentioned on that page), i.e. you'll need to implement the Signing [of] AWS API Requests yourself, unfortunately.
Initial Answer
AWS services in general and Amazon IAM in particular require the Signing [of] AWS API Requests, i.e. you cannot simply call an API endpoint, rather you need your AWS Security Credentials to generate a Digital Signature for each request before submitting it to the API.
The request signing process is a bit complex though and also varies between AWS services, so I'd highly recommend to simply use the AWS SDK for Android instead, which does all the heavy lifting for you - this also applies for any other complexities in dealing with AWS btw., so even if you can conceptually, I'd actually never use AWS without a SDK if there isn't any specific reason to do so (e.g. being on a platform not supported by one of the many offical AWS SDKs yet).
