I need to send a list of strings under a key in the body. Alamofire makes parameters super simple but I can't figure out how to do it in the body of the request. This doesn't help me since its for a simple string and I can't figure out how to make it work for an array of strings: POST request with a simple string in body with Alamofire . This one is titled about a JSON body but the answer is giving them as params Alamofire 4, Swift 3 and building a json body . Does anyone have an answer or a link to something that actually solves my problem?
Code as requested:
var params = ["phone_numbers": [6314560046, 8458200476]] as [String: Any]
Alamofire.request(url, method: .post, parameters: params, encoding: JSONEncoding.default, headers: headers).responseJSON() { response in
With Alamofire, the parameters are the body of the request. This creates your key with value of array of strings:
let parameters = ["Key": ["String1", "String2", "String3"]]
Then use the parameters in making the request:
Alamofire.request(URL, method: .post, parameters: paramaters, encoding: JSONEncoding.default)
.responseJSON { response in
print(response)
}

I am trying to access Spotify's web API. I am currently using Alamofire to request the search operation which only requires a token. However, I could not figure out why it won't let me send multiple arguments.
let headers = ["Authorization": "Bearer {your access token}"]
var searchURL = "https://api.spotify.com/v1/search?q=Odesza&type=track"
AF.request(.GET, url, headers: headers)
.responseJSON { response in
debugPrint(response)
}
Alamofire does a great job of formatting parameters to a request url. Just as you pass parameters with the .post method to the AF request function you also pass a parameters [string : any] to the AF request for .get methods as well. The difference is .post will put the parameters in the request.body/data vs. .get will format the parameters into the url with the ?q=my_search_string
something along the lines of this:
Let params: [string :any] = ["q": "odesza", "type":"track"]
AF.request(.GET, url, parameters:params, headers: headers) .responseJSON { response in debugPrint(response
I'm trying to learn to call API with/without library. But the problem here confuses me.
I have params like this:
let parameters: [String:String] =
["key":"MY_KEY" ,
"q":sourceText,
"source": sourceLanguage),
"target": target)]
let headers: HTTPHeaders = [ "Content-type": "application/json"]
I make a post call like this:
Alamofire.request(urlString, method: HTTPMethod.post, parameters: parameters, headers: headers)
.responseJSON{ response in
guard response.result.error == nil else {
print("error calling POST on /todos/1")
print(response.result.error!)
return
}
// make sure we got some JSON since that's what we expect
guard let json = response.result.value as? [String: Any] else {
print("didn't get todo object as JSON from API")
print("Error: \(response.result.error)")
return
}
By this I get an error 403, saying that I do not have a valid API key (I tested the key with postman, and it is okay).
After many efforts, I have to change the code like this
let stringparams = "key=MY_KEY&q=\(sourceText)&source=\(sourceLanguage)&target=\(target)"
request.httpBody = stringparams.data(using: String.Encoding.utf8)
and using this: Alamofire.request(request)
it works!
I'm using Google Cloud Translation api. And the web use a REST api as said here: https://cloud.google.com/translate/docs/reference/translate
So why can't I use params as dictionary, but using the string (like formdata) will work here?
My guess is Alamofire didn't make the right BODY for the request from the parameters because other arguments is okay. But I don't know why.
And I think Google should accept a json params as they mentioned, in stead of using form data? I did try the original method, but it didn't work with JSON.
From what actually works for you it looks like you need to encode the parameters in the same style as a query. Try this:
struct ParameterQueryEncoding: ParameterEncoding {
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var request = try urlRequest.asURLRequest()
request.httpBody = parameters?
.map { "\($0)=\($1)" }
.joined(separator: "&")
.data(using: .utf8)
return request
}
}
You should then be able to perform the original call that you had before:
Alamofire.request(urlString,
method: HTTPMethod.post,
parameters: parameters,
encoding: ParameterQueryEncoding(),
headers: headers)
.responseJSON { response in
...
}
Try by using JSON encoding. Make sure you have removed ) from dictionary.
Alamofire.request(URL, method: method, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
I have a working scenario using Postman passing in URL parameters. Now when I try to do it via Alamofire in Swift, it does not work.
How would you create this url in Alamofire?
http://localhost:8080/?test=123
_url = "http://localhost:8080/"
let parameters: Parameters = [
"test": "123"
]
Alamofire.request(_url,
method: .post,
parameters: parameters,
encoding: URLEncoding.default,
headers: headers
The problem is that you're using URLEncoding.default. Alamofire interprets URLEncoding.default differently depending on the HTTP method you're using.
For GET, HEAD, and DELETE requests, URLEncoding.default encodes the parameters as a query string and adds it to the URL, but for any other method (such as POST) the parameters get encoded as a query string and sent as the body of the HTTP request.
In order to use a query string in a POST request, you need to change your encoding argument to URLEncoding(destination: .queryString).
You can see more details about how Alamofire handles request parameters here.
Your code should look like:
_url = "http://localhost:8080/"
let parameters: Parameters = [
"test": "123"
]
Alamofire.request(_url,
method: .post,
parameters: parameters,
encoding: URLEncoding(destination: .queryString),
headers: headers)
If you want your parameters to be used in querystring, use .queryString as URLEncoding, as in:
(I assume you have headers somewhere)
let _url = "http://localhost:8080/"
let parameters: Parameters = [
"test": "123"
]
Alamofire.request(_url,
method: .post,
parameters: parameters,
encoding: URLEncoding.queryString,
headers: headers)
This form is suggested by Alamofire author because it's more coincise to the other, see screenshot:

I'm having some trouble converting my old Alamofire code to the new Swift 3 version. I'm getting the error: Extra argument 'method' in call
// Fetch the videos dynamiclly through the YouTube Data API
Alamofire.request("https://www.googleapis.com/youtube/v3/playlistItems", method: .get, parameters: ["part":"snippet", "playlistId":UPLOADS_PLAYLIST_ID,"key":API_KEY], encoding: ParameterEncoding.URL, headers: nil)
Can someone help me with this?
The problem is not in the method argument but in the encoding which you can set to URLEncoding.default also since the header is nil then i guess you dont need it
let parameters: Parameters = ["part":"snippet",
"playlistId":UPLOADS_PLAYLIST_ID,
"key":API_KEY]
let url = "https://www.googleapis.com/youtube/v3/playlistItems"
Alamofire.request(url,
method: .get,
parameters: parameters,
encoding: URLEncoding.default)
.responseData(completionHandler: { response in
//do what you want
})
by the way you can change responseData back to what you already have
This question already has an answer here:
URL Encode Alamofire GET params with SwiftyJSON

Closed 6 years ago.
I am trying to use Alamofire for an Api that has a Json body and a header requirement that needs Basic Authentication. When I test the call in Postman it works fine, however with AlamoFire I am getting a server error.
I am trying to see what the call is that's going out from Alamofire - but I can't seem to see it: (this is the code I am using)
edit:
Error is below
["errors": { }, "errorMessages": <__NSSingleObjectArrayI 0x6000000035c0>( Internal server error ) ]
Request is below
Alamofire.request(endpoint, method: .post, parameters: paramsEncoded, encoding: JSONEncoding.default, headers: headers)
.responseJSON(completionHandler: { (response) in
print(response.request) // This returns just the url eg "http://api.com
print(response.request?.httpBody) // This returns `Optional(85 bytes)`
})
I assume the request is not being created properly, but would be useful to understand what I should be seeing.
Edit: this line helped from the other question :
NSLog("Request: \(request!.httpMethod!) - \(request!.url!.absoluteString)\n\(request!.httpBody.map { body in String(data: body, encoding: .utf8) ?? "" } ?? "")")
Thanks to the question I have linked to as a duplicate for the help.
Print the whole request like this :
let request = Alamofire.request(endpoint, method: .post, parameters: paramsEncoded, encoding: JSONEncoding.default, headers: headers)
.responseJSON(completionHandler: { (response) in
print(response.request)
print(response.request?.httpBody)
})
print("REQUEST = \(request)")
I'm not sure you can get any more info than that though.
You need to add headers with your request.
let urlString = "https://httpbin.org/get"
let headers = ["Authorization": "123456"]
Alamofire.request(urlString, method: .post, parameters: ["foo": "bar"],encoding: JSONEncoding.default, headers: headers).responseJSON { response in
print(response.result.value)
}
