Send NSString as body of post method using NSURLSession - ios

Question

I am trying to post a string to a server using the next example:
// 1
NSURL *url = [NSURL URLWithString:#"YOUR_WEBSERVICE_URL"];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
// 2
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = #"POST";
// 3
NSDictionary *dictionary = #{#"key1": #"value1"};
NSError *error = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:dictionary
options:kNilOptions error:&error];
if (!error) {
// 4
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:data completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
}];
// 5
[uploadTask resume];
}
The difference is that I don't have a NSDictionary But an NSString object that stores an array of dictionaries, and also the string that I post must not be encoded it must be a simple string, so it is visible in the search field if I manually enter it.
My NSString example:
[{
"api_id" = debugger;
at = "2015-02-05T01:41:13Z";
oS = IOS;
ver = "8.10";
what = "showAdAt: forViewController:";
},
{
"api_id" = debugger;
at = "2015-02-05T01:41:13Z";
oS = IOS;
ver = "8.10";
what = "showAdAt: forViewController:";
}
]
Thank you in advance and be patient with me as this is my first post attempt.
I was thinking that the above example should work for me if I first convert the NSString to NSArray with dictionaries as objects.
UPDATE:
Currently I am trying to post the string as:
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{
#"Authorization" : #"CUSTOM AUTHORIZATION THAT I AM USING",
#"Content-Type" : #"application/json"
};
// Create the session
// We can use the delegate to track upload progress
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
// Data uploading task. We could use NSURLSessionUploadTask instead of NSURLSessionDataTask if we needed to support uploads in the background
NSURL *url = [NSURL URLWithString:#"MY WEBSITE LINK"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = #"POST";
//Convert the string to NSData
bodyContainerString = #"[{\"api_id\":\"A124\",\"at\":\"2011-04-10T20:09:31Z\",\"os\":\"ANDROID\",\"ver\":\"2.1\",\"what\":\"TEST\",\"value\":\"\"},{\"api_id\":\"A124\",\"at\":\"2011-04-10T20:10:31Z\",\"os\":\"ANDROID\",\"ver\":\"2.1\",\"what\":\"TEST\",\"value\":\"\"}]";
NSData* jsonData = [bodyContainerString dataUsingEncoding:NSUTF8StringEncoding];
jsonData = [jsonData subdataWithRange:NSMakeRange(0, [jsonData length] - 1)];
NSString* newStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(newStr);
request.HTTPBody = jsonData;
NSURLSessionDataTask *uploadTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// Process the response
NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;
if (!error && httpResp.statusCode == 201) {
//if no error on upload then delete content of plist
NSLog(#"Success on post1");
}
NSLog(#"Success on post2");
}];
[uploadTask resume];
Update 2, the resulting link should look like:
curl -X POST http://MY_LINK/smtg -H 'Authorization: CUSTOM_FIRST_HEADER' -H "Content-Type: application/json" -d '[{"api_id":"A124","at":"2011-04-10T20:09:31Z","os":"ANDROID","ver":"2.1","what":"TEST","value":""},{"api_id":"A124","at":"2011-04-10T20:10:31Z","os":"ANDROID","ver":"2.1","what":"TEST","value":""}]'

Answer 1

I ended up using the first example that I found here is my implementation:
NSURL *url = [NSURL URLWithString:#"MY_LINK/smtg"];
//Create thhe session with custom configuration
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = #{
#"Authorization" : [NSString stringWithFormat:#"BEARER %#",finalToken],
#"Content-Type" : #"application/json"
};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
// 2
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = #"POST";
// 3
NSError *error = nil;
NSData* jsonData = [bodyContainerString dataUsingEncoding:NSUTF8StringEncoding];
if (!error) {
// 4
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:jsonData completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
}];
// 5
[uploadTask resume];
}}
