android HttpPost missing parameter error

Question

I'm trying to post some data to my server(Strings). I'm getting a missing parameter error but i'm not sure why. I log out the contents of the NameValuePair and the data seems to be there.

I'm running this through the emulator. Are there any ideas why the server would reurn such an error if the params are there?

public String updateCall( String userID, String callID, String startTime, String duration, String carerID) {

        Log.e(TAG,"inside WS updateCall");

        DateTime now = new DateTime();
        DateTimeFormatter df = DateTimeFormat.forPattern("yyyy-MM-dd H:mm:ss.SSS");
        String formattedNowTime = df.print(now);


        List<NameValuePair> nameValuePairs = null;
        String serviceStatus = null;
        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://rr3test.carefree-app.co.uk/roadrunner.asmx/UpdateCall");


        userID = userID.trim();
        formattedNowTime = formattedNowTime.trim();
        callID = callID.trim();
        startTime = startTime.trim();
        duration = duration.trim();
        carerID = carerID.trim();



        try {
            // Add your data
            nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("UserID", userID));
            nameValuePairs.add(new BasicNameValuePair("DateTime", formattedNowTime));
            nameValuePairs.add(new BasicNameValuePair("CallID", callID));
            nameValuePairs.add(new BasicNameValuePair("Start", startTime));
            nameValuePairs.add(new BasicNameValuePair("Duration", duration));
            nameValuePairs.add(new BasicNameValuePair("NewCarerID", carerID));

            Log.e(TAG, "userID = " + userID + " DateTime = " + formattedNowTime + " callID = " + callID + " startTime = " + startTime 
                                                                        + " duration = " + duration + " carerID = " + carerID);

            Log.e(TAG, "nameValuePair length = " + nameValuePairs.size());

            for(int i = 0; i < nameValuePairs.size(); i++){

                Log.e(TAG, "nameValuePairs" + nameValuePairs.get(i));

            }

            Log.e(TAG, "about to execute http post updateCall");
            HttpResponse response = httpclient.execute(httppost);


            Log.e(TAG, "just executed http post updateCall");
            String responseBody = EntityUtils.toString(response.getEntity());
            Log.e(TAG, "responseBody = " + responseBody);

            serviceStatus = dp.getPostTransactionResponseCode(responseBody);

            Log.e(TAG, "serviceStatus = " + serviceStatus);

@PiyushGupta hi i've posted the Async. I know it only has 5 params instead of 6 but the 6th one i create in the web method — turtleboy, Feb 18 '14 at 09:29
change this one... from nameValuePairs = new ArrayList(2); to nameValuePairs = new ArrayList(); — Piyush, Feb 18 '14 at 09:33
This is because if you have given the length of 2 it means that you can post 2 item with nameValuePairs. So change it. — Piyush, Feb 18 '14 at 09:36
@PiyushGupta no it makes no difference that. I've sent data before using new ArrayList(2) and there has been 9 Strings sent. I'm not sure if the 2 refers to how many things can be sent? — turtleboy, Feb 18 '14 at 09:41

You get

E/WebService(500): responseBody = Missing parameter: UserID.

while you try

        Log.e(TAG, "responseBody = " + responseBody);

        DocObjModParser dp = new DocObjModParser(context);
        serviceStatus = dp.getPostTransactionResponseCode(responseBody); // <== this fails!

No surprise, DocObjModParser cannot parse the response string "Missing parameter: UserID."

The response suggests adding the user id to the http query.

I'd suggest printing the httppost and trying to perform it via, at first, a browser (it may give you a hint immediately), and, at second, via curl, a command-line utility available in Linux or Cygwin (not sure about plain Windows).

Another suggestion is to compare the printed httppost with a request that works. Who knows, maybe the script is sensitive to the order of parameters or some string contains characters that should be URL-encoded.

UPD: the problem may be with the headers

Doesn't NameValuePair add the UserID to the query via setEntity? – turtleboy Feb 18 '14 at 09:45
looks like. try to print the request URL – 18446744073709551615 Feb 18 '14 at 09:52
ok thanks, how can i print the httpPost? The android api has a few methods like httppost.getEntity, httppost.getHeaders etc but i'm not sure which method will give me the url with params that i send to the server. – turtleboy Feb 18 '14 at 10:27
Try http://developer.android.com/reference/org/apache/http/client/methods/HttpUriRequest.html#getURI() _getURI()_ or http://developer.android.com/reference/org/apache/http/HttpRequest.html#getRequestLine() _getRequestLine()_ – 18446744073709551615 Feb 18 '14 at 10:36
ok i have used the following after setting the Entity on the httppost obj. RequestLine req = httppost.getRequestLine(); it returns the following 02-18 10:50:59.988: E/WebService(956): req = POST http://rr3test.carefree-app.co.uk/roadrunner.asmx/UpdateCallTest HTTP/1.1 – turtleboy Feb 18 '14 at 10:54
I have just tried your URL in a browser: it shows _Missing parameter: UserID._ while https://rr3test.carefree-app.co.uk/roadrunner.asmx/UpdateCallTest&UserID=asd shows _Bad Request_. Are you sure you should use POST rather than GET? – 18446744073709551615 Feb 18 '14 at 11:00
well i think this is the problem. The response from httppost.getRequestLine isn't showing any params, when i am thinking i am adding them in the setEntity. Shouldn't getRequestLine show the params aswell? – turtleboy Feb 18 '14 at 11:08

ah i remember now, they are sent in the body. Is there a way to examine them, i can't see any method in hte API that gets the body or is it a case of using something like fiddler? – turtleboy Feb 18 '14 at 11:32
i just want to see if the params are there or not, how best do that? – turtleboy Feb 18 '14 at 11:32

Thanks for the update. I've changed how i make the request from a POST to a GET and it works now. I need to explain this to the other developer that does the server-side code. If i want to make a POST what does he need to do on the server to accept this way of doing it? – turtleboy Feb 18 '14 at 12:09
I think that developer may ask a question with the _asp.net_ tag here on stackoverflow, if necessary. You may try to search for "ASP.NET http server tutorial post get", the information will most likely pop up immediately. – 18446744073709551615 Feb 18 '14 at 12:29

In seems that the client successfully sent the request to server, but the server response that parameter UserID not found. Please check the server code, one reason may be the server handle parameter with the GET method instead of POST (what you are using to send data now)

Hi It works when i do a GET instead of a POST. I don't write the server-side code. What has the other developer done or what does he have to do to make this work with a POST? Thanks – turtleboy Feb 18 '14 at 12:22

It quite easy to change the way to handle the request from POST to GET, depend on the language the server used. For example, with php, instead of using the $_GET["Parameter_Name"], the developer can use $_POST["Parameter_Name"] – VinhNT Feb 19 '14 at 04:27
