How to send array of dictionarys of JSON in SWIFT - (POST method) - ios

Question

I want to know how I can send more than one array of dictionary in JSON. I have to do POST in this format :
{
"Account":
{
"lastname":"VVV",
"PersonEmail":"vaaaay#gmail.com"
},
"Member":
{
"Password__C":"12345"
},
"ProgramName":"My Chili's"
}
This is what I have done so far:
lname = lastName.text!
fname = firstName.text!
email = emailSignUp.text!
pass = passwordSignup.text!
let signUpDict : [String:Any] =
[
"Account": [
"lastname": lname!,
"PersonEmail": email!
],
"Member": [
"Password__C": pass!
],
"ProgramName": "My Chilli's"
]
var urlRequest = URLRequest(url: URL(string: url)!)
urlRequest.httpMethod = "POST"
urlRequest.setValue("application/json;application/html; charset=utf-8", forHTTPHeaderField: "Content-Type")
urlRequest.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Accept")
do{
let postData = try? JSONSerialization.data(withJSONObject: signUpDict, options: JSONSerialization.WritingOptions.prettyPrinted)
urlRequest.httpBody = postData
}
catch {
print("Couldnt post this")
}
let task = URLSession.shared.dataTask(with:urlRequest as URLRequest){(data,response,error) in
if error != nil{
print("Error is \(error)")
return
}
print("Data Responded : \(data)")
print("response is: \(response)")
}
task.resume()
I am getting a 500 error in response.
{ status code: 500, headers {
"Cache-Control" = "s-maxage=0";
"Content-Security-Policy" = "referrer origin-when-cross-origin";
"Content-Type" = "application/json;charset=UTF-8";
Date = "Tue, 01 Aug 2017 12:19:44 GMT";
"Transfer-Encoding" = Identity;
"X-XSS-Protection" = "1; mode=block";
} })
I think the way I have written the signUpDict could be incorrect or missing something, could someone please guide me through this?
Edit:
As requested I tried the json on POSTMAN, however this is my first time using POSTMAN(complete newbie). So I am not sure if I did it right.

Answer 1

Please Try to use this updated code
lname = lastName.text!
fname = firstName.text!
email = emailSignUp.text!
pass = passwordSignup.text!
let signUpDict : [String:Any] =
[
"Account": [
"lastname": lname!,
"PersonEmail": email!
],
"Member": [
"Password__C": pass!
],
"ProgramName": "My Chilli's"
]
let data = try! JSONSerialization.data(withJSONObject: signUpDict, options: JSONSerialization.WritingOptions.prettyPrinted)
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
if let json = json {
print(json)
}
let jsonData = json!.data(using: String.Encoding.utf8.rawValue);
var request = URLRequest(url: URL(string: url)!)
request.httpMethod = HTTPMethod.post.rawValue
request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData

Answer 2

Replace following line :
From
urlRequest.setValue("application/json;application/html; charset=utf-8", forHTTPHeaderField: "Content-Type")
To
urlRequest.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")

Try This:-
lname = lastName.text!
fname = firstName.text!
email = emailSignUp.text!
pass = passwordSignup.text!
let accountDict = NSMutableDictionary.init()
let memberDict = NSMutableDictionary.init()
let finalDict = NSMutableDictionary.init()
accountDict.setValue(lname, forKey: "lastname")
accountDict.setValue(email, forKey: "PersonEmail")
memberDict.setValue(pass, forKey: "Password__C")
finalDict.setValue(accountDict, forKey: "Account")
finalDict.setValue(memberDict, forKey: "Member")
finalDict.setValue("My Chili's", forKey: "ProgramName")
print(finalDict)
let data = try! JSONSerialization.data(withJSONObject: finalDict, options: JSONSerialization.WritingOptions.prettyPrinted)
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
if let json = json {
print(json)
}
let jsonData = json!.data(using: String.Encoding.utf8.rawValue);
var request = URLRequest(url: URL(string: url)!)
request.httpMethod = HTTPMethod.post.rawValue
request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
