How to post raw data in swift 3? - ios

Question

If I post raw data using Postman, response is coming. I am using this code
var dict = Dictionary<String, Any>()
dict = ["user_id" :userid as AnyObject, "type" :type as AnyObject, "complaint_id" :complaintId as AnyObject, "auth_code" : authCode as AnyObject, "isSkip" :isSkip as AnyObject]
let url:URL = URL(string: "http://development.easystartup.org/prigovo/Backend/detailed_complaint/index.php")!
let session = URLSession.shared
var postData = NSData()
do{
postData = try JSONSerialization.data(withJSONObject: dict, options: JSONSerialization.WritingOptions.prettyPrinted) as NSData!
}catch {
print("error")
}
var request = URLRequest(url: url)
request.httpMethod = "POST"
// request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData
request.setValue("\(postData.length)", forHTTPHeaderField: "Content-Length")
request.setValue("text/html", forHTTPHeaderField: "Content-Type")
request.setValue("json/application", forHTTPHeaderField: "Accept")
request.httpBody = postData as Data
let task = session.dataTask(with: request as URLRequest) {
(
data, response, error) in
guard let data = data, let _:URLResponse = response, error == nil else {
print("error")
return
}
let dataString = String(data: data, encoding: String.Encoding.utf8)
print(dataString ?? "no data")
}
task.resume()
Getting data of 0 bytes everyTime. Already tried with Alamofire but no response.
Also I tried in Objective C where I am getting response, code is :
NSURL *url = [NSURL URLWithString:urlStr];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:[NSString stringWithFormat:#"%lu", (unsigned long)postData.length] forHTTPHeaderField:#"Content-Length"];
[request setValue:#"text/html" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error = nil;
NSHTTPURLResponse *response = nil;
[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSData *retData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if (error)
{
//error
NSLog(#"error");
return #"";
}
else
{
NSLog(#"No error");
NSString *charlieSendString = [[NSString alloc] initWithData:retData encoding:NSUTF8StringEncoding];
NSLog(#"data come : %#",charlieSendString);
return charlieSendString;
}
Posted "dict" in Log :
["complaint_id": COMBRD1, "user_id": USR9, "type": complaint_brand, "auth_code": KL1hwYrAhNVnSgT, "is_skip": 2]

var dict = Dictionary<String, Any>()
dict = ["user_id" :userid, "type" :type, "complaint_id" :complaintId,"auth_code" : authCode, "is_skip" :isSkip]
var jsonData = NSData()
// var dataString2 :String = ""
do {
jsonData = try JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted) as NSData
// you can now cast it with the right type
} catch {
print(error.localizedDescription)
}
let url:URL = URL(string: "http://Backend/detailed_complaint/index.php")!
let session = URLSession.shared
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("\(jsonData.length)", forHTTPHeaderField: "Content-Length")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData as Data
let task = session.dataTask(with: request as URLRequest) {
(
data, response, error) in
guard let data = data, let _:URLResponse = response, error == nil else {
print("error")
return
}
let dataString = String(data: data, encoding: String.Encoding.utf8)
print("no data",dataString ?? "no data")
}
task.resume()
