i have created one common class for alamofire request
i want to send parameters as aplication/x-www-form-urlencoded
how to add the parameters to my urlRequest
i have managed to add parameters as application/json to urlRequest using below code
do {
urlRequest.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: [])
} catch {
throw AFError.parameterEncodingFailed(reason: .jsonEncodingFailed(error: error))
}
i need something similar for aplication/x-www-form-urlencoded
here is my parameters
case .ewalletData :
return [K.APIParameterKey.token :"OP8JHOEOZ5KJW1X",K.APIParameterKey.fromMobile:"true",K.APIParameterKey.adminName:"binaryecom",K.APIParameterKey.limit:"100",K.APIParameterKey.offset:"0",K.APIParameterKey.userName:"OC6DGH"]
here is the code it works for me in swift 4:
let postString = "your parameter="+value+"&your parameter="+value
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request, completionHandler: completionHandle)
task.resume()
try this :
guard let request_url = URL(string: Url) else { return }
let parameterDictionary = ["your parameter" : value]
var request = URLRequest(url: request_url)
request.httpMethod = "POST"
request.setValue("Application/json", forHTTPHeaderField: "Content-Type")
request.setValue("aplication/x-www-form-urlencoded", forHTTPHeaderField: "String")
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameterDictionary, options: []) else {
return
}
request.httpBody = httpBody

Sorry For this my English is weak
I try many types of a solution but not working in Xcode 11.2.1 and swift 5
I try this
var urlRequest = URLRequest(url: URL(string: "https://xxxxxx/login")!)
urlRequest.httpMethod = "POST"
let params = [
"username": SessionManager.shared.username!,
"password": SessionManager.shared.password!,
"vhost": "standard"
]
let postString = self.getPostString(params: params)
urlRequest.httpBody = postString.data(using: .utf8)
webView.load(urlRequest)
...
//helper method to build url form request
func getPostString(params:[String:String]) -> String
{
var data = [String]()
for(key, value) in params
{
data.append(key + "=\(value)")
}
return data.map { String($0) }.joined(separator: "&")
}
and this
Post Request with Parameter
And also try to add below lines in my code
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
But not Working
I fire the Request because not working the WKWebView screen is Open but not Load request.
If I not set navigationDelegate and open normal URL then it is working completely
If I set navigationDelegate then blank page come in all Request Like Normal URL fire or post parameter URL fire, All are coming to Blank Page in
I can't understand what is the Problem with WKWebView
Please help me.
Thanks in advance
The request body uses the same format as the query string:
parameter=value&also=another
Therefore the content type of your request is of type application/x-www-form-urlencoded :
let postString = self.getPostString(params: params)
urlRequest.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
urlRequest.httpMethod = "POST"
urlRequest.httpBody = postString.data(using: .utf8)
webView.load(urlRequest)
Try this, we will initiate a POST request using URLSession convert the data returned by the server to String and instead of loading the url we will use loadHTMLString which will:
Set the webpage contents and base URL.
and the content is our converted string::-
var request = URLRequest(url: URL(string: "http://www.yourWebsite")!)
request.httpMethod = "POST"
let params = "Your Parameters"
request.httpBody = params.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { (data : Data?, response : URLResponse?, error : Error?) in
if data != nil {
if let returnString = String(data: data!, encoding: .utf8) {
self.webView.loadHTMLString(returnString, baseURL: URL(string: "http://www.yourWebsite.com")!)
}
}
}
task.resume()
I think we not need to use URLSession.dataTask, simply create URLRequest and declare your method + with stating header fields like this:
private final func postRequestToURL(_ urlString: String) {
guard let url = URL(string: urlString) else {
debugPrint("Error: Invailed URL!")
return
}
var parameters = Parameters()
parameters["name"] = "Example"
parameters["surname"] = "ExmpleExample"
parameters["timeZone"] = "MiddleEast/MENA"
parameters["test"] = "YES"
var urlRequest = URLRequest(url: url)
urlRequest.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
urlRequest.setValue("application/json", forHTTPHeaderField: "Accept")
urlRequest.allowsCellularAccess = true
urlRequest.httpMethod = "POST"
let postString = parameters.getPostString()
urlRequest.httpBody = postString.data(using: .utf8)
if let wkNavigation = self.webView.load(urlRequest) {
debugPrint("Success: \(wkNavigation.description)")
} else {
debugPrint("Failure: Cannot load current request.")
}
}
Here we can convert our parameters to String by this extension:
public extension Dictionary where Key == String, Value == Any {
func getPostString() -> String {
var data = [String]()
for(key, value) in self {
data.append(key + "=\(value)")
}
return data.map { String($0) }.joined(separator: "&")
}
}
I am using this code over my commercial app.
Additional info: I allowed request eligible to run over cellular by marking allowsCellularAccess = true this is optional
How to pass HTTPBody like this content type in urlrequest
below is the code which i tried from postman code -
var semaphore = DispatchSemaphore (value: 0)
let parameters = "code=httagtsgdgtdfsg&client_secret=agsfstf&Grant_type=authorization_code"
let postData = parameters.data(using: .utf8)
var request = URLRequest(url: URL(string: "url")!,timeoutInterval: Double.infinity)
request.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "HTTPMethod"
request.httpBody = postData
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data else {
print(String(describing: error))
return
}
print(String(data: data, encoding: .utf8)!)
semaphore.signal()
}
task.resume()
semaphore.wait()
What's this?
request.httpMethod = "HTTPMethod"
It should be
request.httpMethod = "POST"
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let httpbody = object.data(using: String.Encoding.utf8)
request.httpBody = httpbody
You can directly generate a code from postman itself. Also, for your reference, you can call post request with row body as given below.
let headers = [
"content-type": "application/json",
"cache-control": "no-cache"
]
let parameters = ["order": ["line_items": [
["variant_id": 18055889387589,
"quantity": 1]
]]] as [String : Any]
let postData = try? JSONSerialization.data(withJSONObject: parameters, options: [])
if let data = postData {
let request = NSMutableURLRequest(url: NSURL(string: "http://")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = data as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error?.localizedDescription ?? "")
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse?.statusCode ?? 0)
let reponseData = String(data: data!, encoding: String.Encoding.utf8)
print("responseData: \(reponseData ?? "Blank Data")")
}
})
dataTask.resume()
}
Let me know if you have any query.
Thanks.
I am trying to receive and process a POST request being sent from my iOS app to my Node.js web server. The server responds with HTTP Error 502 whenever I try to send this POST request. Could you please look at my code below and see what is wrong with it? Thank you!
Node.js Code
app.post('/applogin', function(req, res) {
var parsedBody = JSON.parse(req.body);
console.log(parsedBody)
});
Swift Code (POST function)
func httpPost(jsonData: Data) {
if !jsonData.isEmpty {
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = jsonData
URLSession.shared.getAllTasks { (openTasks: [URLSessionTask]) in
NSLog("open tasks: \(openTasks)")
}
let task = URLSession.shared.dataTask(with: request, completionHandler: { (responseData: Data?, response: URLResponse?, error: Error?) in
NSLog("\(response)")
})
task.resume()
}
}
Swift Code (sending of the POST request)
#IBAction func onClick(_ sender: Any) {
let username = Username.text
let password = Password.text
var dataString = "username: \(username), password: \(password)"
let data = dataString.data(using: .utf8)
httpPost(jsonData: data!)
}
Thanks in advance!
You have to send a json instead dataString, and you have to set the "Content Type" header with value "application/json"
Swift 2
let request = NSMutableURLRequest(URL: requestUrl)
request.HTTPMethod = "POST"
let params = ["username" : username, "password" : password] as Dictionary<String, AnyObject>
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options:NSJSONWritingOptions.PrettyPrinted)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
Many answers they don't mention that we need to set header for the request from Swift side before sending to the backend otherwise it'll be a string in a wrong format that we can't use JSON.parse, here's what I firgured out (NOTE the IMPORTANT line):
let json = [
"email": emailTextField.text
]
let jsonData = try! JSONSerialization.data(withJSONObject: json)
let url = URL(string: BASE_URL + "/auth/register")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
// insert json data to the request
request.httpBody = jsonData
//IMPORTANT
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
if let responseJSON = responseJSON as? [String: Any] {
print(responseJSON)
}
}
task.resume()
And in your NodeJS with Express just call req.body and you're done
Try this:
app.post('/applogin', function(req, res) {
var parsedBody = JSON.parse(req.body);
console.log(parsedBody)
res.send("Request received")
});
I'm trying to send a Patch request with a serialized JSON Body.
For some reason the server is not able to receive the body properly. I have a feeling that there seems to be a problem with the PATCH method in combination with the http request body.
let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)
var URL = B2MFetcher.urlForBooking(event.unique, bookingID: booking.unique)
let request = NSMutableURLRequest(URL: URL)
request.HTTPMethod = "PATCH"
// Headers
println(token)
request.addValue(token, forHTTPHeaderField: "Authorization")
request.addValue("gzip, identity", forHTTPHeaderField: "Accept-Encoding")
// JSON Body
let bodyObject = [
"op": "cancel"
]
var jsonError: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(bodyObject, options: nil, error: &jsonError)
/* Start a new Task */
let task = session.dataTaskWithRequest(request, completionHandler: { (data : NSData!, response : NSURLResponse!, error : NSError!) -> Void in
completion(data: data, response:response , error: error)
})
task.resume()
You could try to add a Content-Type header to the request:
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
or use one of the other JSON Content-Type formats described here.
I tested it with an ExpressJS server and without the Content-Type header the server got an empty body, but with a Content-Type header it worked well.
in swift 3/4 :
let request = NSMutableURLRequest(url: NSURL(string: "http://XXX/xx/xxx/xx")! as URL)
request.httpMethod = "PATCH"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
do{
let json: [String: Any] = ["status": "test"]
let jsonData = try? JSONSerialization.data(withJSONObject: json)
request.httpBody = jsonData
print("jsonData: ", String(data: request.httpBody!, encoding: .utf8) ?? "no body data")
} catch {
print("ERROR")
}
let task = URLSession.shared.dataTask(with: request as URLRequest) {
data, response, error in
if error != nil {
print("error=\(error)")
completion(false)
return
}
let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print("responseString = \(responseString)")
completion(true)
return
}
task.resume()
Simple Way to use patch without using HTTPBody
If you want to just use patch, you just need to change the value of the name of a specific user then it will be like:
let myurl = URL(string: "https://gorest.co.in/public-api/users/"+"\(id)?"+"name=abc")!
var request = URLRequest(url:myurl)
request.addValue("Bearer yourAuthorizationToken",forHTTPHeaderField:"Authorization")
request.httpMethod = "PATCH"
let dataTask = URLSession.shared.dataTask(with: request)
dataTask.resume()
Note: here "id" will be userId
