Send Curl from objective-c Xcode - ios

Question

How can I send cURL with Xcode ?
this is the Shell code send to REST Api Server.
Convert shell to objective-c code
curl --include \
--request POST \
--header "Content-Type: application/json; charset=utf-8" \
--header "Authorization: Basic NGEwMGZmMjItY2NkNy0xMWUzLTk5ZDUtMDAwYzI5NDBlNjJj" \
--data-binary "{\"app_id\": \"5eb5a37e-b458-11e3-ac11-000c2940e62c\",
\"contents\": {\"en\": \"English Message\"},
\"included_segments\": [\"Active Users\"]}" \
https://onesignal.com/api/v1/notifications
what is wrong here ?
The jsonData input is the problem for me
NSURL *url = [NSURL URLWithString:#"https://onesignal.com/api/v1/notifications"];
NSMutableURLRequest *rq = [NSMutableURLRequest requestWithURL:url];
[rq setHTTPMethod:#"POST"];
NSData *jsonData = [#"{\"app_id\": \"5eb5a37e-b458-11e3-ac11-000c2940e62c\",
\"contents\": {\"en\": \"English Message\"},
\"included_segments\": [\"Active Users\"]}" \" dataUsingEncoding:NSUTF8StringEncoding];
[rq setHTTPBody:jsonData];
[rq setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[rq setValue:#"Basic O645372ZjItM2NiOC00ZjQ2LTk4Y2UtYjFlMjE5ODBiYzg2" forHTTPHeaderField:#"Authorization"];
[rq setValue:[NSString stringWithFormat:#"%ld", (long)[jsonData length]] forHTTPHeaderField:#"Content-Length"];
[NSURLConnection sendAsynchronousRequest:rq completion:^(NSURLResponse *rsp, NSData *data, NSError *err) {
NSLog(#"POST sent!");
}];
It is also possible to include an NSString in the message ( NSDictionary )
NSString *message = #"Test Message 123";
NSDictionary *postBody = #{
#"app_id":#"5eb5a37e-b458-11e3-ac11-000c2940e62c",
#"contents": #{#"en":#"%#", message},
#"included_segments": #[#"All"]
};

My answer is
NSDictionary *postBody = #{
#"app_id":#"5eb5a37e-b458-11e3-ac11-000c2940e62c",
#"contents": #{#"en":#"English Message"},
#"included_segments": #[#"All"]
};
NSData *data = [NSJSONSerialization dataWithJSONObject:postBody options:0 error:nil];
NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"https://onesignal.com/api/v1/notifications"]];
//create the Method "POST"
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setValue:#"application/json;charset=UTF-8" forHTTPHeaderField:#"content-type"];
[urlRequest setValue:#"Basic O645372ZjItM2NiOC00ZjQ2LTk4Y2UtYjFlMjE5ODBiYzg2" forHTTPHeaderField:#"Authorization"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *dataTask = [session uploadTaskWithRequest: urlRequest
fromData:data completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if(data == nil && error){
NSLog(#"uploadTaskWithRequest error: %#", error);
}
else{
id jsonResp = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
if([jsonResp isKindOfClass:[NSDictionary class]]){
NSDictionary *dictRes = [jsonResp copy];
NSLog(#"The dictRes is - %#",dictRes);
}
else{
NSArray *arrRes = [jsonResp copy];
NSLog(#"The dictRes is - %#",arrRes);
}
}
}];
[dataTask resume];
I got it from Create notification - Sends notifications to your users
also from One Signal

Look up the docs for NSURLSession (URLSession if you're using Swift)—it's a good starting point if you're looking to do networking on iOS.
