How to download PDF use NSURLSession POST with headers and body parameters?












0















I try this on Postman and it works (got 200), it can download PDF. But when I tried to download it return responseString = {"detail":"JSON parse error - No JSON object could be decoded"}
and got 400.



@IBAction func downloadPDF(_ sender: Any) {
let url = URL(string: "https://api-apuat2.tokiomarine-life.co.id/sam/money_analysis_report/")!
var request = URLRequest(url: url)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwidXNlcl9pZCI6OTg1NSwianRpIjoiZGMzY2Q3ZTE3NjNkNDUwNzg1NjA3NGVjODVhYzA1MTgiLCJleHAiOjE1NDcwMDA0MjJ9.6y92gdz36i1L9mJ3BUYAiEf8xVR2YM85xLiubQELoGA", forHTTPHeaderField: "Authorization")
request.httpMethod = "POST"
let postString = "contact_id="
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else { // check for fundamental networking error
print("error=(error!)")
return
}

if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is (httpStatus.statusCode)")
print("response = (response!)")
}

let responseString = String(data: data, encoding: .utf8)
print("responseString = (responseString!)")
}
task.resume()
}


How to repair (the correct code) this so when I click button, it automatically download PDF?
