Not able to understand Bing JSON response

Question

My code:

NSString *urlString = [NSString stringWithFormat:@"%@%@%@%@", @"http://api.search.live.net/json.aspx?Appid=am hiding the appid &query=",text,@"&sources=web&web.offset=",offvalue];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];

The JSON response:

SearchResponse =     {
        Errors =         (
                        {
                Code = 1002;
                HelpUrl = "http://msdn.microsoft.com/en-us/library/dd251042.aspx";
                Message = "Parameter has invalid value.";
                Parameter = "SearchRequest.AppId";
                Value = " am hiding the value";
            }
        );
        Query =         {
            SearchTerms = iphone;
        };
        Version = "2.2";
    };
}

What wrong am I doing here.Can anyone please rectify my query??How to use version 2.2 of the bing API

The query is wrong, NSLog it and figure out how it is different that what you would type into Bing. — zaph, Oct 14 '13 at 23:51
Maybe you need to add a slash ('/') at the end of the urlstring. — AdamG, Oct 14 '13 at 23:52
replace your query string with `NSString *urlString = [NSString stringWithFormat:@"http://api.search.live.net/json.aspx?Appid=YOUR_APP_ID&query=%@&sources=web&web.offset=%@",text,offvalue];` — Dipen Panchasara, Oct 15 '13 at 04:32

It looks like you entered the wrong AppID judging from.

Parameter = "SearchRequest.AppId";

Make sure that the AppID matches the appID that they assigned your app with the service.

Also (and this sometimes randomly causes issues for me) make sure you put a / at the end of the URL String.

I am using the same appID. – TryingToLearn Oct 15 '13 at 00:23
In my account I have primary key and Customer ID.I tried using both but parameter has invalid value. – TryingToLearn Oct 15 '13 at 00:28
You normally have to register your app for an app id so it wouldn't be a primary key or customer id. See if there is a register app or add new app button somewhere. – AdamG Oct 15 '13 at 00:47
Rak, try making the object called AppId not Appid. – AdamG Oct 15 '13 at 02:26
The line in the urlString AppId not Appid. The variable name might be mislabeled. – AdamG Oct 15 '13 at 02:41

What is the value of 'text', is this one word or multiple words? You'll need to perform URL_Encode on the parameter 'text' in order to have a valid URL.

See Objective-C and Swift URL encoding Be sure only to have the URL_Encoding on the text-object and not on the whole URL, otherwise "http://" will be encoded as well, resulting in an invalid URL as well

Eg a space should be %20 , you can verify this by adding a NSLog of the URL

Text value of depends on the user who types it in the textfield.I am not really getting the concepts of URL_Encoding.please hep me on that. – TryingToLearn Oct 15 '13 at 00:44
Let say, the user types "small sentence" , in your case, this will make a URL like http://server.com/api/?para1=small sentence&para2=abc" (eg). A space is not valid in a URL, the valid URL is "http://server.com/api/?para1=small%20sentence&para2=abc" . You can test this by pasting a URL with a space inside the Safari addressbar, Safari will replace the space by %20 etc. You will need to process the input of the user by replacing spaces and other 'strange chars' to the correct %xx values. See http://stackoverflow.com/questions/8086584/objective-c-url-encoding for the solution how to encode – Jelle De Laender Oct 15 '13 at 00:47
NSString* encoded_text = [self.encodeText:text]; NSString *urlString = [NSString stringWithFormat:@"%@%@%@%@", @"http://api.search.live.net/json.aspx?Appid=am hiding the appid &query=",encoded_text,@"&sources=web&web.offset=",offvalue]; where self.encodeText: the method is that will handle the encoding of the parameter – Jelle De Laender Oct 15 '13 at 00:48
-(NSString*)encodeText:(NSString *)string { NSString *newString = (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, NULL, CFSTR(":/?#[]@!$ &'()*+,;=\"<>%{}|\\^~`"), CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)); if (newString) { return newString; } return @""; } – TryingToLearn Oct 15 '13 at 00:55
you need to implement the method to do the encoding, see http://stackoverflow.com/questions/8086584/objective-c-url-encoding as this describes this problem, and also shows the solution how the encode the parameter. (see approved answer there) – Jelle De Laender Oct 15 '13 at 01:00
Also see http://stackoverflow.com/questions/8088473/url-encode-an-nsstring and the approved answer - you can test your method easily with NSLog, spaces should be replaced by %20 etc. – Jelle De Laender Oct 15 '13 at 01:02
@rak did you succeed by encoding the text-parameter? Did this fixed the problem you had? If so, can you approve and accept this solution? – Jelle De Laender Oct 15 '13 at 11:25
Sure Jelle,thanks for the help.. I have one more question how to send image as binary to the server and in turn it gives me json output – TryingToLearn Oct 15 '13 at 11:45
@rak you should open a new question for that, as it's different, but in general, sending binary information will need to be done by making a POST - Request. Please perform some research on POST-Requests. Eg http://stackoverflow.com/questions/7184967/objective-c-post-data-using-nsurlconnection - This question is closed as it was missing url_encode. – Jelle De Laender Oct 15 '13 at 12:08
follow this question http://stackoverflow.com/questions/19380980/send-image-as-a-binary-file-to-the-server – TryingToLearn Oct 15 '13 at 12:17
