    <p>I need to send request like this:</p> <pre><code>"http://api.site.com/login?q={"meta":{"api_key":"cb2f734a14ee3527b3"},"request":{"id":"username@host.name","password":"passw0rd"}}` </code></pre> <p>...the response to which should look like <code>{"id":399205,"token":"d43f8b2fe37aa19ac7057701"}</code> To do so, I have tried the following code:</p> <pre><code>self.responseData = [NSMutableData data]; NSDictionary *apiKeyDict = [NSDictionary dictionaryWithObject:@"cb2f734a14ee3527b3" forKey:@"api_key"]; NSDictionary *idPasswordDict = [NSDictionary dictionaryWithObjectsAndKeys:@"tc-d@gmail.com",@"id", @"abc",@"password", nil]; NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:apiKeyDict, @"meta", idPasswordDict, @"request", nil]; NSURL *url = [NSURL URLWithString:@"http://api.site.com/login?="]; NSError *error = nil; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&amp;error]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody: requestData]; NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self]; if (connection) { self.recievedData = [NSMutableData data]; } </code></pre> <p>Later on, I get in the following:</p> <pre><code>- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [self.recievedData appendData:data]; NSLog(@"%@",[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]); } </code></pre> <p>The response data comes back as "<code>&lt;h1&gt;CHttpException&lt;/h1&gt;&lt;p&gt;wrong sign&lt;/p&gt;</code>" As I understand, the way of adding json data to the current url is not appropriate in this case. Does anyone have advice on how I can fix this?</p> <p>resolve my problem. Convert posted json to appended string to base url-string. that's how I did it:</p> <pre><code>NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&amp;error]; NSMutableString *dictString = [[NSMutableString alloc]initWithData:requestData encoding:NSUTF8StringEncoding]; [dictString insertString:@"http://api.site.com/login?q=" atIndex:0]; //don't know why but dictString contains a lot of @"\n" and spaces to present it nice-formated. [dictString replaceOccurrencesOfString:@"\n" withString:@"" options:nil range:NSMakeRange(0, dictString.length)]; [dictString replaceOccurrencesOfString:@" " withString:@"" options:nil range:NSMakeRange(0, dictString.length)]; NSURL *url = [NSURL URLWithString:[dictString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; </code></pre> <p>if it helps someone will appreciate tick near this issue=)</p>

    1. CORight off, Your example at the top is showing a GET rather than a POST. GET uses params in the URL, where POST sends data in the message body.

    2. COYou tried to set query parameters to the URL, but you didn't actually set any. Thus, the error response (in HTML). You should consult the API documentation of the web service. Possibly, you need a different Content-Type. Or just try the URL omitting the partial query string (the two characters "?=").

    3. CO@KHansenSF Actually, a POST request may have query params in the URL - this is just rarely done in practice. ;)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
