I seem to be running into an error each time I try to make a payment transaction where Stripe declines the operation by saying "Not a valid URL". The client-side is in Swift, while the server is in Python, deployed on Heroku.
A suggestion I saw on another post was to register my server webhook with my Stripe account, which I did, but it doesn't seem to solve the problem.
For reference, here is my createPaymentIntent function:
func createPaymentIntent(dict: [String:Any]) {
let url = self.baseURL.appendingPathComponent("create-payment-intent")
let params = dict
let jsondata = try? JSONSerialization.data(withJSONObject: params)
var clientSecretOut = ""
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsondata
let task = URLSession.shared.dataTask(with: request, completionHandler: { [weak self] (data, response, error) in
guard let response = response as? HTTPURLResponse,
response.statusCode == 200,
let data = data,
let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any],
let clientSecret = json["clientSecret"] as? String else {
let message = error?.localizedDescription ?? "Failed to decode response from server."
print("Error: ", message)
return
}
clientSecretOut = clientSecret
print("client out inside: ", clientSecretOut)
self?.clientSecretFinal = clientSecret
})
task.resume()
}
And here is the place where the error seems to be called– my didCreatePaymentResultFunction:
func paymentContext(_ paymentContext: STPPaymentContext, didCreatePaymentResult paymentResult: STPPaymentResult, completion: #escaping STPPaymentStatusBlock) {
let paymentIntentParams = STPPaymentIntentParams(clientSecret: self.clientSecretFinal)
paymentIntentParams.configure(with: paymentResult)
paymentIntentParams.returnURL = "meURLStripeTest://"
STPPaymentHandler.shared().confirmPayment(withParams: paymentIntentParams, authenticationContext: paymentContext) { status, paymentIntent, error in
switch status {
case .succeeded:
print("success")
completion(.success, nil)
case .failed:
print("cant", error)
completion(.error, error)
case .canceled:
completion(.userCancellation, nil)
#unknown default:
completion(.error, nil)
}
}
}
Thanks for your help!
The problem is in this line:
paymentIntentParams.returnURL = "meURLStripeTest://"
The returnURL has to be a valid URL or application URI scheme, in your case it's neither. See here on how to create an application URI scheme for your app.

below is my get request code. but getting 403 error ...please help!
func getUser(completion: #escaping(Result<User?, AuthenticationError>)-> Void) {
let loginVM = LoginViewModel()
let token = loginVM.accessToken
guard let url = URL(string: myURL) else {
completion(.failure(.custom(errorMessage: "URL is not correct")))
return
}
var request = URLRequest(url:url)
request.httpMethod = "GET"
request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
URLSession.shared.dataTask(with: request) { (data, response, error) in
guard let data = data, error == nil else {
completion(.failure(.custom(errorMessage: "No data")))
return
}
guard let registerResponse = try? JSONDecoder().decode(User.self, from: data) else{
completion(.failure(.custom(errorMessage: "no response")))
return
}
completion(.success(User))
}.resume()
}
and instruction from my backend guy for this part is this :
I tested on Postman It work as like charm. It must be happen in my request code with Authorization....
I'm just learning Web APIs with Swift.
And I've done as follows
Make some basic configuration
let session = URLSession(configuration: .default)
// Prepare URL #the URL is virtual now
let url = URL(string: "http://something.com/api")
guard let requestUrl = url else { fatalError() }
// Prepare URL Request Object
var request = URLRequest(url: requestUrl)
request.httpMethod = "POST"
Set Post parameter
let parameters: [String: String] = [
"user_ID": "1",
]
let jsonData = try JSONEncoder().encode(parameters)
request.httpBody = jsonData
Take request to our web api
// Perform HTTP Request
let task = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
// Check for Error
if let error = error {
print("Error took place \(error)")
return
}
guard let data = data else { return }
do {
let myEnterprise = try JSONDecoder().decode(Enterprise.self, from: data)
print("Response data:\n \(myEnterprise)")
print("Response data:\n \(myEnterprise.returnData)")
} catch let jsonErr {
print(jsonErr)
}
}
task.resume()
myEnterprise is always nil. Can anyone help me?
I have done my Post-request but I am unsure about how to make it possible to send a full question and to get the most common answers back to my app.
I am in such a big need of this code in my program so would love to get some examples on how to make it work
Have tried to right the question into the parameters with a "+" instead of space which resulted into nothing.
#IBAction func GetAnswer(_ sender: Any) {
let myUrl = URL(string: "http://www.google.com/search?q=");
var request = URLRequest(url:myUrl!)
request.httpMethod = "POST"
let postString = questionAsked;
request.httpBody = postString.data(using: String.Encoding.utf8);
let task = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
if error != nil
{
print("error=\(String(describing: error))")
return
}
print("response = \(String(describing: response))")
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
if let parseJSON = json {
let answer = parseJSON[" Answer "] as? String
self.AnswerView.text = ("Anwer: \(String(describing: answer))")
}
} catch {
print(error)
}
}
task.resume()
}
You do not use google.com/search, please check the api documentation
Paste following in Playground, should give a good start
struct Constants {
static let apiKey = "YOUR_API_KEY"
static let bundleId = "YOUR_IOS_APP_BUNDLE_ID"
static let searchEngineId = "YOUR_SEARCH_ENGINE_ID"
}
func googleSearch(term: String, callback:#escaping ([(title: String, url: String)]?) -> Void) {
let urlString = String(format: "https://www.googleapis.com/customsearch/v1?q=%#&cx=%#&key=%#", term, Constants.searchEngineId, Constants.apiKey)
let encodedUrl = urlString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
guard let url = URL(string: encodedUrl ?? urlString) else {
print("invalid url \(urlString)")
return
}
let request = NSMutableURLRequest(url: url, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10)
request.httpMethod = "GET"
request.setValue(Constants.bundleId, forHTTPHeaderField: "X-Ios-Bundle-Identifier")
let session = URLSession.shared
let datatask = session.dataTask(with: request as URLRequest) { (data, response, error) in
guard
error == nil,
let data = data,
let json = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String : Any]
else {
// error handing here
callback(nil)
return
}
guard let items = json["items"] as? [[String : Any]], items.count > 0 else {
print("no results")
return
}
callback(items.map { ($0["title"] as! String, $0["formattedUrl"] as! String) })
}
datatask.resume()
}
Usage
googleSearch(term: "George Bush") { results in
print(results ?? [])
}
Create a new search engine using following url
https://cse.google.com/cse/create/new
If you would like search entire web, use following steps
edit your engine using https://cse.google.com/cse/setup/basic?cx=SEARCH_ENGINE_ID
remove any pages listed under Sites to search
turn on Search the entire web
I trying to send a POST request in swift for example :
url = "http://localhost:9080/mfp/api/az/v1/token"
Headers :
Authorization = "Basic UGlua0NhclBhc3NlbmdlcjoxMjM0"
Content-Type = "application/x-www-form-urlencoded"
Body :
grant_type = client_credentials
scope = RegisteredClient messages.write push.application.com.XXX
What's simple way to do it ?
I've tried by use IBMMobileFirstPlatformFoundation SDK, it's return error "Can't not connect to server",but i'm sure that the connect still good... Here's my code :
let urlString = "http://localhost:9080/mfp/api/az/v1/token"
let url1 = URL(string: urlString)
let request1 = WLResourceRequest(url: url1! as URL, method: WLHttpMethodPost)!
request1.addHeaderValue("Basic UGlua0NhclBhc3NlbmdlcjoxMjM0" as NSObject, forName: "Authorization")
request1.addHeaderValue("application/x-www-form-urlencoded" as NSObject, forName: "Content-Type")
request1.send(withBody: "{\"grant_type\":\"client_credentials\",\"scope\":\"RegisteredClient messages.write push.application.com.XXX\"}", completionHandler: { (response, error) in
if error == nil {
print("Response : ")
print(response)
} else {
print("Error : ")
print(error)
}
})
You can use Alamofire as ZassX suggested or you can use URLSession.
I have some code as an example:
func postRequest(toUrl url: String, accessKey: String?, completion: #escaping(Data?, HTTPURLResponse?, Error?, AnyObject?) -> Void){
let requestUrl = NSURL(string: url)
let request = NSMutableURLRequest(url: requestUrl! as URL)
if accessKey != nil {
request.setValue("\(accessKey!)", forHTTPHeaderField: "Authorization")
}
request.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
request.httpBody = yourBody
URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data,response,error) in
if let content = data{
do{
let myJSON = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
completion(data as Data?, response as? HTTPURLResponse, error, myJSON)
}
catch{
print("JSON ERROR")
}
}else{
completion(data as Data?, response as? HTTPURLResponse, error, nil)
}
}).resume()
}
First, you don't manually manage the security token when you're using the MobileFirst SDK, it's handled automatically.
Next, WLResourceRequest() takes a URL that is relative to the MobileFirst server URL (http://localhost:9080/mfp, in your case). You can see that "base" URL in your mfpclient.plist file.
Your code will then look something like
let request = WLResourceRequest(
URL: NSURL(string: "/adapters/MyAdapter/myResource"),
method: WLHttpMethodGet
)
See https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/8.0/application-development/resource-request/ios/
I've wrote a function for GET request from rest and it says that i have method not allowed - code 405 which is werid and i can not find solution for that.
I am doing GET via current token which was assigned to the user after logged in.
Could someone have a look on the code and tell me what might be wrong ?
func getRequest() -> Void {
let json: [String: Any] = ["token": SessionMenager.Instance.token]
let jsonData = try? JSONSerialization.data(withJSONObject: json)
// create post request
let url = URL(string: MY_URL)!
var request = URLRequest(url: url)
request.httpMethod = "GET"
// insert json data to the request
request.httpBody = jsonData
request.setValue("application/json;charest=utf-8", forHTTPHeaderField: "Content-Type")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
if let httpResponse = response as? HTTPURLResponse {
print("GET : code - \(httpResponse.statusCode)")
}
let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
if let responseJSON = responseJSON as? [String: Any] {
print(responseJSON)
} else{
print(error.debugDescription)
}
}
task.resume()
}
Thanks in advance!!
