So here is the thing, Im trying to use Almofire to post header and a body (as string) to an API.
_ = Alamofire.request("http://myurl", method: .post, parameters: param, encoding: JSONEncoding.default, headers: ["Authorization" : token])
.responseJSON { response in
switch response.result {
case .success(let data):
let json = JSON(data)
print(json)
case .failure( let error):
_ = SweetAlert().showAlert("Data Error!", subTitle: "Something Is Wrong!! Please contact Support", style: AlertStyle.warning)
}}
this works fine..
However I cant figure out how to pass a body string (this is the ID i pass to get data) API does not accept any parametrs (as key value or json) unless if it is just a String (ID). any help would be greatly appreciated.
Add custom parameter like below
var customParameters = [String : String]()
customParameters["key1"] = "Value1"
customParameters["key2"] = "Value2"
_ = Alamofire.request("http://myurl", method: .post, parameters: customParameters, encoding: JSONEncoding.default, headers: ["Authorization" : token])
.responseJSON { response in
switch response.result {
case .success(let data):
let json = JSON(data)
print(json)
case .failure( let error):
_ = SweetAlert().showAlert("Data Error!", subTitle: "Something Is Wrong!! Please contact Support", style: AlertStyle.warning)
}}
I found the answer from https://stackoverflow.com/a/42513496/8099966. this imethod can sed a String value on body. So changed my code like this ..
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!
}}
then call the API like this...
_ = Alamofire.request("http://myurl.com", method: .post, parameters: param, encoding: JSONStringArrayEncoding.init(string: "my String id to send"), headers: ["Authorization" : 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 don't know if I am posting the parameters correctly?
func removeCart(rowId: Int, completion: #escaping (Bool)->()) {
let urlString = "\(BaseUrl.Protina.rawValue)/ApiShoppingCart/UpdateCart"
let headers: HTTPHeaders = ["Content-Type": "application/form-data"]
let parameters : [String: Any] = ["removefromcart": rowId]
Alamofire.request(urlString, method: .post, parameters: parameters,encoding: JSONEncoding.default, headers: headers).responseJSON { response in
switch response.result {
case .success(let data):
let jsonData = JSON(data)
print(jsonData)
completion(true)
case .failure(let error):
print(error)
}
}
}
when a user tries to remove an item from the cart, the above function gets fired
and after item deleted the rest of the items from cart will return.
Also, I tested it with postman and it was successful.
I found the answer, the problem was in the parameter and encoding.
Changed it to this:
let parameters: [String:Any]= [
"removefromcart": rowId,
"Content-Type" : "application/form-data"
]
And the encoding should be URLEncoding.httpBody
I am using like this, but in this case, I need to call API with parameters and Body. Please help me. Thanks in advance.
Alamofire.request(postUrl, method: .post, parameters: params, encoding: CustomPostEncoding(), headers: nil).validate().responseJSON{ response in

I'm having a problem on using Alamofire. When I try to post a request using a generic parameters like ["name":"John", "age":"27"] it always succeeds. But, when I try to use a web service that requires parameters and a body-raw for a base64 string I'm not able to get a successful response from the server. Though it succeeds when I use Postman. Does anyone knows how to do this on Alamofire 4? Here is the screenshot of my postman.
Thank you!
#nathan- this is the code that I used. I just assumed that the base64String inside the "let paramsDict" has a key value named "data" though it doesn't have a key name in postman.
let urlString = ApiManager.sharedInstance.formsURL + ApiManager.sharedInstance.mobileFormsImageUpload
let paramsDict = ["token": token, "fileID":"2", "filename":"images.png", "data": base64String] as [String : Any]
Alamofire.request(urlString, method: .post, parameters: paramsDict, encoding: URLEncoding.httpBody, headers: [:])
.responseJSON{ response in
switch response.result {
case .success(let data):
debugPrint("SUCCESS")
case .failure(let error):
debugPrint("Request Error")
}
}
I already figured it out. It needs a custom encoding to make it work. All the parameters must be inlined with the url so the base64 string inside the parameter is the only to be encoded. Here is the code that I used.
struct CustomPostEncoding: ParameterEncoding {
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var request = try URLEncoding().encode(urlRequest, with: parameters)
let base64 = parameters?["data"] as! String
let finalBase64Format = "\"" + base64 + "\""
let postData = NSData(data: finalBase64Format.data(using: String.Encoding.utf8)!)
request.httpBody = postData as Data
return request
}
}
func uploadImageBase64(){
let jpegCompressionQuality: CGFloat = 0.9 // Set this to whatever suits your purpose
if let base64String = UIImageJPEGRepresentation(testIMG, jpegCompressionQuality)?.base64EncodedString() {
var token = String()
if let data = UserDefaults.standard.data(forKey: "userProfile"),
let user = NSKeyedUnarchiver.unarchiveObject(with: data) as? UserProfile{
token = user.token
} else {
print("There is an issue")
}
let headers = [
"content-Type": "application/json"
]
let urlString = "http://localhost/FormsService.svc/Getbase64?filename=test.png&fileID=1151&token=80977580xxx"
let paramsDict = ["data": base64String] as [String : Any]
Alamofire.request(urlString, method: .post, parameters: paramsDict, encoding: CustomPostEncoding(), headers: headers)
.responseJSON{ response in
print("response JSON \(response.result)")
}
.response{ response in
print("RESPONSE \(response)")
}
}
}
I'm using Swift 3 and Alamofire 4.0.
I want to create similar Alamofire POST request as Postman request shown in screenshot:
I've tried with these lines of code:
var parameters: [String: Any] = [
"client_id" : "xxxxxx",
"client_secret" : "xxxxx",
"device_token" : "xxxx",
"fullname" : "xxxxx",
"gender": "xxx"
]
Alamofire.request(url, method: .post, parameters: parameters).responseJSON { response in
print(response)
}
But I got this error:
How to implement POST request with Body as form-data using Alamofire in Swift 3?
Swift 3.0 - Alamofire - Working code for multipart form data upload *
// Parameters
let params: [String : String] =
["UserId" : "\(userID)",

]
// And upload
Alamofire.upload(
multipartFormData: { multipartFormData in
for (key, value) in params
{

}
},

Let me know if you still have issues with it.
after too much try I have succeded so try this
override func viewDidLoad() {
super.viewDidLoad()
let parameters: Parameters = ["client_id": "1","user_token":"xxxxxxxx"]
// Do any additional setup after loading the view, typically from a nib.
let url = "http://xxxxxxxxxxx/index.php/Web_api/get_client_profile"
//let timeParameter = self.getLastTimeStamp()
self.request = Alamofire.request(url, method: .post, parameters:parameters)
if let request = request as? DataRequest {
request.responseString { response in
//PKHUD.sharedHUD.hide()
do{
let dictionary = try JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.allowFragments) as! NSDictionary
print(dictionary)
}catch{
}
}
}
}
var request: Alamofire.Request? {
didSet {
//oldValue?.cancel()
}
}
You can post a request using Alamofire.
let url = ""
let headers = [ "Content-Type" : "application/json"]
let para : Parameters = [ "data" : JSONObject]
Alamofire.request(url, method: .post, parameters: para, encoding: JSONEncoding.default, headers : headers)
.responseJSON { response in
print(response)
print(response.result)
}
Nothing to worry about.
Alamofire request method not changed so much(For Swift 3.0) if in case you know how to do that in Swift 2.0/2.2. If you understand the old method then you can easily understand this one also. Now lets take a closer look on the following boilerplate -
Alamofire.request(apiToHit, method: .post, parameters: parametersObject, encoding: JSONEncoding.default, headers: headerForApi).responseJSON { response in switch response.result{
case .success(_):
if let receivedData: Any = response.result.value{
if let statusCode: Int = response.response?.statusCode {
//Got the status code and data. Do your data pursing task from here.
}
}else{
//Response data is not valid, So do some other calculations here
}
case .failure(_):
//Api request process failed. Check for errors here.
}
Now here in my case -
apiToHit //Your api url string
.post //Method of the request. You can change this method as per you need like .post, .get, .put, .delete etc.
parametersObject // Parameters needed for this particular api. Same in case you are sending the "body" on postman etc. Remember this parameters should be in form of [String: Any]. If you don't need this then you can just pass nil.
JSONEncoding.default //This the encoding process. In my case I am setting this as .default which is expected here. You can change this to .prettyPrinted also if you need.
headerForApi //This is the header which you want to send while you are requesting the api. In my case it is in [String: String] format. If you don't need this then you can just pass nil.
.responseJSON //Expecting the response as in JSON format. You can also change this as you need.
Now, in my request I am using Switch inside the request closure to check the result like response in switch response.result{.
Inside case .success(_): case I am also checking for result data and http status code as well like this
if let receivedData: Any = response.result.value{
if let statusCode: Int = response.response?.statusCode {
}
}
Hope this helped. Thanks.
