I'm doing a POST call to server but Alamofire always send the body as a JSON and not as a Form URL Encoded, I do know that in oder to encode the body I have to insert data(using: .utf8, allowLossyConversion: false), but I don't know where.
How can I fix my code?
This is my actual code:
func asURLRequest() throws -> URLRequest {
let url = try DBank.StagingServer.baseUrl.asURL()
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
// HTTP Method
urlRequest.httpMethod = method.rawValue
// Common Headers
headers.forEach { (field, value) in
urlRequest.setValue(value, forHTTPHeaderField: field)
}
// Parameters
if let parameters = parameters {
do {
urlRequest.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: [])
} catch {
throw AFError.parameterEncodingFailed(reason: .jsonEncodingFailed(error: error))
}
}
I'm guessing you have response handler like below:
Alamofire.request(url, method: .post, parameters: params, encoding: URLEncoding(destination: .queryString), headers: headers)
.validate(statusCode: 200..<300)
.responseString { response in
//response.result.value will contain http response from your post call
}
With the result from this response you would set:
UserDefaults.standard.set("<result>", forKey: "<token>")
I am trying to send POST HTTP request with body using Alamofire and would appreciate any help.
My body:
{"data":{"gym":{"country":"USA","city":"San Diego","id":1}}}
Should I do something like this?
let parameters: [String: Any] = [ "data": [
"gym": [
"country":"USA",
"city":"San Diego",
"id":1
]]]
Alamofire.request(URL, method: .post, parameters: parameters, headers: headers())
.responseJSON { response in
print(response)
}
If you wish to send the parameters in json format use encoding as JSONEncoding. So add parameter for encoding in request as follows:
Alamofire.request(URL, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers())
.responseJSON { response in
print(response)
}
Hope it helps...
Try this method to convert your json string to dictionary
func convertToDictionary(text: String) -> [String: Any]? {
if let data = text.data(using: .utf8) {
do {
return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
} catch {
print(error.localizedDescription)
}
}
return nil
}
let str = "{\"data\":{\"gym\":{\"country\":\"USA\",\"city\":\"San Diego\",\"id\":1}}}"
let dict = convertToDictionary(text: str)
and send dictionary as a param in your request.
Alamofire.request(URL, method: .post, parameters: dict, headers: headers())
.responseJSON { response in
print(response)
}
ref : How to convert a JSON string to a dictionary?
What I think is that you should try and prepare your dictionary in the this format:
var gym = [String:Any]()
gym["country"] = "USA"
gym["city"] = "San"
var data = [[String:Any]]()
data.append(gym)
var metaData = [String:Any]()
metaData["data"] = data
Your parameters is wrong...
let parameters: [String: Any] = { "data":
{
"gym": {
"country":"USA",
"city":"San Diego",
"id":1
}
}
}
Alamofire.request(<YOUR-URL>,
method: .post,
parameters: parameters,
encoding: URLEncoding(destination: .queryString),
headers: <YOUR-HEADER>
).validate().responseString { response in
switch response.result {
case .success:
debugPrint("Good to go.")
debugPrint(response)
case .failure:
let errMsg = String(data: response.data!, encoding: String.Encoding.utf8)!
debugPrint(errMsg)
debugPrint(response)
}
}
Hope this help. BTW, in Alamofire 5, debugPrint(response) can print out response.data directly.
You can use the httpBody property of URLRequest along with Alamofire Session request:
var req = try? URLRequest(url: url, method: method, headers: headers)
req?.httpBody = someJson
Alamofire.Session(configuration: .default).request(req!).validate().response { response in
// Handle the response
}
I'm using Alamofire to do a get request to Yelp api, i got my post request woking but my get request is not working what so ever, i have tried everything i read from other questions but still no solution. here are my codes.
This is my post request which is working.
class func getAccessToken() {
let parameters: Parameters = ["client_id": client_id, "client_secret": client_secret]
Alamofire.request("https://api.yelp.com/oauth2/token", method: .post, parameters: parameters, encoding: URLEncoding.default, headers: nil).response {
response in
print("Request: \((response.request)!)")
print("Response: \((response.response)!)")
if let data = response.data {
let dict = try! JSONSerialization.jsonObject(with: data, options: []) as! NSDictionary
print("Access Token: \((dict["access_token"])!)")
self.accessToken = (dict["access_token"])! as? String
self.tokenType = (dict["token_type"])! as? String
}
}
}
This is my get request that i'm having trouble with.
class func getRestaurents(searchTerm: String) {
let parameters: Parameters = ["term": searchTerm, "location": "******"]
let headers: HTTPHeaders = [tokenType!: accessToken!]
Alamofire.request("https://api.yelp.com/v3/businesses/search", method: .get, parameters: Parameters, encoding: JSONEncoding.default, headers: headers).response {
response in
if let data = response.data {
let dict = try! JSONSerialization.jsonObject(with: data, options: [] as! [NSDictionary])
print(dict)
}
}
}
Thank you.
You are passing class Parameters instead of its object parameters.
Alamofire.request("https://api.yelp.com/v3/businesses/search", method: .get, parameters: Parameters, encoding: JSONEncoding.default, headers: headers).response {
Should be:
Alamofire.request("https://api.yelp.com/v3/businesses/search", method: .get, parameters: parameters, encoding: JSONEncoding.default, headers: headers).response {
I updated my project to Swift 3 and Alamofire 4. I was using custom Encoding, but it's changed to other encoding methods. I am not able to find the alternative/equivalent to this:
alamoFire.request(urlString, method: HTTPMethod.post, parameters: [:], encoding: .Custom({
(convertible, params) in
let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
let data = (body as NSString).data(using: String.Encoding.utf8)
mutableRequest.httpBody = data
return (mutableRequest, nil)
}), headers: headers()).responseJSON { (responseObject) -> Void in
switch responseObject.result {
case .success(let JSON):
success(responseObject: JSON)
case .failure(let error):
failure(error: responseObject)
}
}
I also tried by making URLRequest object and simple request its also giving me errors
var request = URLRequest(url: URL(string: urlString)!)
let data = (body as NSString).data(using: String.Encoding.utf8.rawValue)
request.httpBody = data
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers()
alamoFire.request(request).responseJSON { (responseObject) -> Void in
switch responseObject.result {
case .success(let JSON):
success(JSON)
case .failure(let error):
failure(responseObject, error)
}
}
Do point me in some direction, how to attach httpbody with the Alamofire 4
Try this method?
Alamofire.request(url, method: HTTPMethod.post, parameters: parameters, encoding: URLEncoding.httpBody, headers: nil).responseObject(completionHandler: { (response : DataResponse<T>) in
})
In Alamofire 4.0 you should use ParameterEncoding protocol. Here is an example, which makes any String UTF8 encodable.
extension String: ParameterEncoding {
public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var request = try urlRequest.asURLRequest()
request.httpBody = data(using: .utf8, allowLossyConversion: false)
return request
}
}
Alamofire.request("http://mywebsite.com/post-request", method: .post, parameters: [:], encoding: "myBody", headers: [:])
how is it possible to send a POST request with a simple string in the HTTP body with Alamofire in my iOS app?
As default Alamofire needs parameters for a request:
Alamofire.request(.POST, "http://mywebsite.example/post-request", parameters: ["foo": "bar"])
These parameters contain key-value-pairs. But I don't want to send a request with a key-value string in the HTTP body.
I mean something like this:
Alamofire.request(.POST, "http://mywebsite.example/post-request", body: "myBodyString")
Your example Alamofire.request(.POST, "http://mywebsite.example/post-request", parameters: ["foo": "bar"]) already contains "foo=bar" string as its body.
But if you really want string with custom format. You can do this:
Alamofire.request(.POST, "http://mywebsite.example/post-request", parameters: [:], encoding: .Custom({
(convertible, params) in
var mutableRequest = convertible.URLRequest.copy() as NSMutableURLRequest
mutableRequest.HTTPBody = "myBodyString".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
return (mutableRequest, nil)
}))
Note: parameters should not be nil
UPDATE (Alamofire 4.0, Swift 3.0):
In Alamofire 4.0 API has changed. So for custom encoding we need value/object which conforms to ParameterEncoding protocol.
extension String: ParameterEncoding {
public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var request = try urlRequest.asURLRequest()
request.httpBody = data(using: .utf8, allowLossyConversion: false)
return request
}
}
Alamofire.request("http://mywebsite.example/post-request", method: .post, parameters: [:], encoding: "myBody", headers: [:])
You can do this:
I created a separated request Alamofire object.
Convert string to Data
Put in httpBody the data
var request = URLRequest(url: URL(string: url)!)
request.httpMethod = HTTPMethod.post.rawValue
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let pjson = attendences.toJSONString(prettyPrint: false)
let data = (pjson?.data(using: .utf8))! as Data
request.httpBody = data
Alamofire.request(request).responseJSON { (response) in
print(response)
}
If you use Alamofire, it is enough to set encoding type to URLEncoding.httpBody
With that, you can send your data as a string in the httpbody although you defined it as json in your code.
It worked for me..
Updated for Badr Filali's question:
var url = "http://..."
let _headers : HTTPHeaders = ["Content-Type":"application/x-www-form-urlencoded"]
let params : Parameters = ["grant_type":"password","username":"mail","password":"pass"]
let url = NSURL(string:"url" as String)
request(url, method: .post, parameters: params, encoding: URLEncoding.httpBody, headers: _headers).responseJSON(
completionHandler: { response in response
let jsonResponse = response.result.value as! NSDictionary
if jsonResponse["access_token"] != nil
{
access_token = String(describing: jsonResponse["accesstoken"]!)
}
})
I modified #Silmaril's answer to extend Alamofire's Manager.
This solution uses EVReflection to serialize an object directly:
//Extend Alamofire so it can do POSTs with a JSON body from passed object
extension Alamofire.Manager {
public class func request(
method: Alamofire.Method,
_ URLString: URLStringConvertible,
bodyObject: EVObject)
-> Request
{
return Manager.sharedInstance.request(
method,
URLString,
parameters: [:],
encoding: .Custom({ (convertible, params) in
let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
mutableRequest.HTTPBody = bodyObject.toJsonString().dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
return (mutableRequest, nil)
})
)
}
}
Then you can use it like this:
Alamofire.Manager.request(.POST, endpointUrlString, bodyObject: myObjectToPost)
Based on Illya Krit's answer
Details
Xcode Version 10.2.1 (10E1001)
Swift 5
Alamofire 4.8.2
Solution
import Alamofire
struct BodyStringEncoding: ParameterEncoding {
private let body: String
init(body: String) { self.body = body }
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
guard var urlRequest = urlRequest.urlRequest else { throw Errors.emptyURLRequest }
guard let data = body.data(using: .utf8) else { throw Errors.encodingProblem }
urlRequest.httpBody = data
return urlRequest
}
}
extension BodyStringEncoding {
enum Errors: Error {
case emptyURLRequest
case encodingProblem
}
}
extension BodyStringEncoding.Errors: LocalizedError {
var errorDescription: String? {
switch self {
case .emptyURLRequest: return "Empty url request"
case .encodingProblem: return "Encoding problem"
}
}
}
Usage
Alamofire.request(url, method: .post, parameters: nil, encoding: BodyStringEncoding(body: text), headers: headers).responseJSON { response in
print(response)
}
If you want to post string as raw body in request
return Alamofire.request(.POST, "http://mywebsite.com/post-request" , parameters: [:], encoding: .Custom({
(convertible, params) in
let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
let data = ("myBodyString" as NSString).dataUsingEncoding(NSUTF8StringEncoding)
mutableRequest.HTTPBody = data
return (mutableRequest, nil)
}))
I have done it for array from strings. This solution is adjusted for string in body.
The "native" way from Alamofire 4:
struct JSONStringArrayEncoding: ParameterEncoding {
private let myString: String
init(string: String) {
self.myString = string
}
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var urlRequest = urlRequest.urlRequest
let data = myString.data(using: .utf8)!
if urlRequest?.value(forHTTPHeaderField: "Content-Type") == nil {
urlRequest?.setValue("application/json", forHTTPHeaderField: "Content-Type")
}
urlRequest?.httpBody = data
return urlRequest!
}
}
And then make your request with:
Alamofire.request("your url string", method: .post, parameters: [:], encoding: JSONStringArrayEncoding.init(string: "My string for body"), headers: [:])
I've used answer of #afrodev as reference. In my case I take parameter to my function as string that have to be posted in request. So, here is the code:
func defineOriginalLanguage(ofText: String) {
let text = ofText
let stringURL = basicURL + "identify?version=2018-05-01"
let url = URL(string: stringURL)
var request = URLRequest(url: url!)
request.httpMethod = HTTPMethod.post.rawValue
request.setValue("text/plain", forHTTPHeaderField: "Content-Type")
request.httpBody = text.data(using: .utf8)
Alamofire.request(request)
.responseJSON { response in
print(response)
}
}
func paramsFromJSON(json: String) -> [String : AnyObject]?
{
let objectData: NSData = (json.dataUsingEncoding(NSUTF8StringEncoding))!
var jsonDict: [ String : AnyObject]!
do {
jsonDict = try NSJSONSerialization.JSONObjectWithData(objectData, options: .MutableContainers) as! [ String : AnyObject]
return jsonDict
} catch {
print("JSON serialization failed: \(error)")
return nil
}
}
let json = Mapper().toJSONString(loginJSON, prettyPrint: false)
Alamofire.request(.POST, url + "/login", parameters: paramsFromJSON(json!), encoding: .JSON)
My case, posting alamofire with content-type: "Content-Type":"application/x-www-form-urlencoded", I had to change encoding of alampfire post request
from : JSONENCODING.DEFAULT
to: URLEncoding.httpBody
here:
let url = ServicesURls.register_token()
let body = [
"UserName": "Minus28",
"grant_type": "password",
"Password": "1a29fcd1-2adb-4eaa-9abf-b86607f87085",
"DeviceNumber": "e9c156d2ab5421e5",
"AppNotificationKey": "test-test-test",
"RegistrationEmail": email,
"RegistrationPassword": password,
"RegistrationType": 2
] as [String : Any]
Alamofire.request(url, method: .post, parameters: body, encoding: URLEncoding.httpBody , headers: setUpHeaders()).log().responseJSON { (response) in
let parameters = ["foo": "bar"]
// All three of these calls are equivalent
AF.request("https://httpbin.org/post", method: .post, parameters: parameters)
AF.request("https://httpbin.org/post", method: .post, parameters: parameters, encoder: URLEncodedFormParameterEncoder.default)
AF.request("https://httpbin.org/post", method: .post, parameters: parameters, encoder: URLEncodedFormParameterEncoder(destination: .httpBody))
Xcode 8.X , Swift 3.X
Easy Use;
let params:NSMutableDictionary? = ["foo": "bar"];
let ulr = NSURL(string:"http://mywebsite.com/post-request" as String)
let request = NSMutableURLRequest(url: ulr! as URL)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let data = try! JSONSerialization.data(withJSONObject: params!, options: JSONSerialization.WritingOptions.prettyPrinted)
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
if let json = json {
print(json)
}
request.httpBody = json!.data(using: String.Encoding.utf8.rawValue);
Alamofire.request(request as! URLRequestConvertible)
.responseJSON { response in
// do whatever you want here
print(response.request)
print(response.response)
print(response.data)
print(response.result)
}
