I want to pass the array inside the dictionary parameter with URL POST method

Question

I am new to json, I want to pass the NSArray inside the NSDictionary as a parameter along with the url to server, how it can be done while method is post ? I had tried sample codes but not found my exact solution.below is my sample code

     NSDictionary *dict = [[NSDictionary alloc]   initWithObjectsAndKeys:@"contact_name", @"kumar",@"designantion",@"sales", nil];
    NSDictionary *finalDict = [[NSDictionary alloc] initWithObjectsAndKeys:dict, @"OfficeContactPerson", nil];



    NSString *post =[[NSString alloc]initWithFormat:@"name=%@&short_name=%@&shop_no=%@&door_no=%@&floor=%@&building=%@&street=%@&area=%@&main=%@&city=%@&state=%@&district=%@&pincode=%@&telephone=%@&contact_name=%@&designatio=%@&mobile=%@&email=%@&OfficeContactPerson=%@",self.txtshowroom.text,self.txtshortname.text,self.txtshop.text,self.txtdoor.text,self.txtfloor.text,self.txtbuilding.text,self.txtstreet.text,self.txtarea.text,self.txtmain.text,cityineger,stateintegervalue,districtintegervalue,self.txtpincode.text,self.txttel.text,self.txtname.text,self.txtdesign.text,self.txtmbl.text,self.txtemail.text,finalDict];

    NSLog(@"postdata :%@",post);


    NSURL *url=[NSURL URLWithString:@"http://139.59.252.34:1337/office"];
    NSData *postData=[post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    NSString *postlength=[NSString stringWithFormat:@"%lu",(unsigned long)[postData length]];
    NSMutableURLRequest *request= [[NSMutableURLRequest alloc]init];

    [request setURL:url];
    [request setHTTPMethod:@"POST"];
    [request setValue:postlength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSError *error=[[NSError alloc]init];
    NSHTTPURLResponse *response=nil;
    NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];


if (!urlData){


    UIAlertView *alert =[[UIAlertView alloc]initWithTitle:@"Error"message:FS_ERROR_LOCALIZED_DESCRIPTION(error.code)
                                                   delegate:nil
                                          cancelButtonTitle:@"OK" 
                                          otherButtonTitles:nil];
    [alert show];

}
else
{
    NSString *responseData=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
    NSLog(@"Response data ----->%@",responseData);
    NSError *error=nil;
    NSDictionary *jsonData=[NSJSONSerialization JSONObjectWithData:urlData options:NSJSONReadingMutableContainers error:&error];

);
}

Convert array into json string or make dictionary of post data than convert it into json string and post string to server. I hope below code will work for you. This code is works fine for me-

NSDictionary *dict = [[NSDictionary alloc]   initWithObjectsAndKeys:@"contact_name", @"kumar",@"designantion",@"sales", nil];
NSDictionary *finalDict = [[NSDictionary alloc] initWithObjectsAndKeys:dict, @"OfficeContactPerson", nil];

NSURL *url=[NSURL URLWithString:@"http://139.59.252.34:1337/office"];
NSData *postData=[[[NSString alloc]initWithData:[NSJSONSerialization dataWithJSONObject:finalDict options:NSJSONWritingPrettyPrinted error:nil] encoding:NSUTF8StringEncoding] dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postlength=[NSString stringWithFormat:@"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request= [[NSMutableURLRequest alloc]init];

[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postlength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

NSError *error=[[NSError alloc]init];
NSHTTPURLResponse *response=nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];


if (!urlData){


    UIAlertView *alert =[[UIAlertView alloc]initWithTitle:@"Error"message:[NSString stringWithFormat:@"%ld",(long)(error.code)]
                                                 delegate:nil
                                        cancelButtonTitle:@"OK"
                                        otherButtonTitles:nil];
    [alert show];

}
else
{
    NSString *responseData=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
    NSLog(@"Response data ----->%@",responseData);
    NSError *error=nil;
    NSDictionary *jsonData=[NSJSONSerialization JSONObjectWithData:urlData options:NSJSONReadingMutableContainers error:&error];


}

Rohit Khandelwal Over a year ago

is this dictionary or array ?

vshnu Over a year ago

array inside dictionary

Rohit Khandelwal Over a year ago

your above 'post' string is not in correct json formate which you are post to server. Make a key/value pair for each data using dictionary like you have done in your first line of code.

I'm new in ios app development but I try to solve.lets assume that these are your string.Try this code:

    NSString *messages-getModuleMessages=@"messages-getModuleMessages";
NSString * authtincateToken=@"WWc3ZFZCcEtWcGxLTk1hZHhEb2hMelFNZzdGcXgwdTBxeU51NWFwUE44TnkrcnF5SCtSMDxxxxxxx";
NSString *accessSecretkey =@"WWc3ZFZCcEtWcGxLTk1hZHhEb2hMelFNZzdGcXgwdTBxeU51NWFwUE44TnkrcnF5SCtxxxxxxxx";
NSString *inboxvalue =@"hai thios is textmessage";

// this is your dictionary value are you passed
NSDictionary * callDict = [NSDictionary dictionaryWithObjectsAndKeys:messages-getModuleMessages,@"call",authtincateToken,@"authToken", accessSecretkey, @"accessSecret",inboxvalue,@"calotype",@"json",@"format",nil];

  // convert your dictionary to NSData
  NSData *jsonData = [NSJSONSerialization dataWithJSONObject:callDict options:kNilOptions error:nil];
 // this is your service request url
  NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://xxxxxxxx"]];
 // set the content as format
 [request setHTTPMethod:@"POST"];
[request setHTTPBody: jsonData];
  // this is your response type        
 [request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"content-type"];
   NSError *err;
  NSURLResponse *response;
   // send the synchronous connection
   NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
   // here add your server response NSJSONSerialization
  NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err]; 

  // if u want to check the data in console
  NSString *tmp=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
    NSLog(@"%@", tmp);

Try below line of code and put them place of first two line of line code. Problem is only there.

    NSDictionary *dict = [[NSDictionary alloc]   initWithObjectsAndKeys:@"contact_name", @"kumar",@"designantion",@"sales", nil];
    NSDictionary *finalDict = [[NSDictionary alloc] initWithObjectsAndKeys:[NSArray arrayWithObject:dict], @"OfficeContactPerson", nil];
NSData *POST_Params = [NSJSONSerialization dataWithJSONObject:urlParams options:NSJSONWritingPrettyPrinted error:nil]; // Pass these post data in request

Hope this will work for you!!
