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)
Suppose i have a URL "http://aewfwfpi.staginwwedwfg.dewfewf.io/mobile/v1/network/station/10/timetablesss"
where 10 in the above URL is the stationId and can be any number .
How can i POST a request with changing parameter(StationId) in the URL using alamofire?
Should i add it in Parameter section?
Please help
Currently am calling it statically like below:-
Alamofire.request(
"http://aewfwfpi.staginwwedwfg.dewfewf.io/mobile/v1/network/station/10/timetablesss",
parameters:nil,
headers: nil)
var id = 123
var yourURL = "http://aewfwfpi.staginwwedwfg.dewfewf.io/mobile/v1/network/station/\(id)/timetablesss"
use \(variableName) to insert variables or constants in a string
Headers is where you specify the format of the content that you want to send and receive.
example of headers:
let headers: HTTPHeaders = [
"Accept": "application/json",
"Content-Type": "application/json"
]
Parameters is where you put the data that you want to send (POST)
example of parameters:
let pararameters: [String, Any] = [
"name": name as String,
"id": id as Int,
]
To do a POST request, add the parameters to the body of the request and not the url itself.
Something like below is what you must follow:
let parameters: Parameters = ["parameter-name": parameterValue]
let headers = ["Content-Type":"application/json"]
Alamofire.request("<your post url>",method: .post, parameters: parameters, encoding: JSONEncoding.default,headers: headers)
.responseJSON { response in
print(response)
// Do anything you like with the response here
}
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 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 using Alamofire to make a post request to server. The post request is working fine.
Issue: When the post request is made, it returns some data which I need. How can I store/ retrieve that data
The POST Request:
Alamofire.request(.POST, postURL, parameters: params)
to get the response closure add
.response { request, response, data, error in }
to the end of your code
ie
Alamofire.request(.POST, "http://httpbin.org/get", parameters: ["foo": "bar"])
.response { request, response, data, error in
print(request)
print(response)
print(data)
print(error)
}
If you are using the latest version of AlamoFire.
If you are using the latest version of AlamoFire.
Try this working fine for me.(Change request arguments based on your need)
let url1 = "http://yoururl.com"
let head = [ "Accept": "application/json;charset=UTF-8",
"Content-Type": "application/json;charset=UTF-8"] // Adding headers
let p = ["Email":"anything","Password": "123"] // Adding parameters if any
Alamofire.request(.POST,url1, parameters: p, encoding : .JSON, headers : head)
.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
}
