I am using AFNetworking for the first time and attempting to make a get call using the FourSquare Places API. When I test with the endpoint on FourSquare's documentation website, my url with params works, but not with AFNetworking code. I keep getting a 400.
func findCoffee(coordinate: CLLocationCoordinate2D) {
let url = "https://api.foursquare.com/v2/venues/explore"
let params = [
"ll": "\(coordinate.latitude),\(coordinate.longitude)",
"intent": intent,
"limit": limit,
"client_id": "\(clientId)",
"client_secret": "\(clientSecret)"
]
let manager = AFHTTPSessionManager()
manager.requestSerializer = AFHTTPRequestSerializer()
manager.get(url, parameters: params, success: { (operation, responseObject) in
}) { (operation, error) in
}
}

I know this question is asked a lot, but I can't figure out how to apply any answers to my program. Sorry in advance this async stuff makes absolutely zero sense to me.
Basically, I have a button in SwiftUI that, when pressed, calls a function that makes two API calls to Google Sheets using Alamofire and GoogleSignIn.
Button("Search") {
if fullName != "" {
print(SheetsAPI.nameSearch(name: fullName, user: vm.getUser()) ?? "Error")
}
}
This function should return the values of some cells on success or nil on an error. However, it only ever prints out "Error". Here is the function code.
static func nameSearch<S: StringProtocol>(name: S, advisory: S = "", user: GIDGoogleUser?) -> [String]? {
let name = String(name)
let advisory = String(advisory)
let writeRange = "'App Control'!A2:C2"
let readRange = "'App Control'!A4:V4"
// This function can only ever run when user is logged in, ! should be fine?
let user = user!
let parameters: [String: Any] = [
"range": writeRange,
"values": [
[
name,
nil,
advisory
]
]
]
// What I want to be returned
var data: [String]?
// Google Identity said use this wrapper so that the OAuth tokens refresh
user.authentication.do { authentication, error in
guard error == nil else { return }
guard let authentication = authentication else { return }
// Get the access token to attach it to a REST or gRPC request.
let token = authentication.accessToken
let headers: HTTPHeaders = ["Authorization": "Bearer \(token)"]
AF.request("url", method: .put, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseString { response in
switch response.result {
case .success:
// I assume there is a better way to make two API calls...
AF.request("anotherURL", headers: headers).responseDecodable(of: NameResponseModel.self) { response2 in
switch response2.result {
case .success:
guard let responseData = response2.value else { return }
data = responseData.values[0]
// print(responseData.values[0]) works fine
case .failure:
print(response2.error ?? "Unknown error.")
data = nil
}
}
case .failure:
print(response.error ?? "Unknown error.")
data = nil
}
}
}
// Always returns nil, "Unknown error." never printed
return data
}
The model struct for my second AF request:
struct NameResponseModel: Decodable { let values: [[String]] }
An example API response for the second AF request:
{
"range": "'App Control'!A4:V4",
"majorDimension": "ROWS",
"values": [
[
"Bob Jones",
"A1234",
"Cathy Jones",
"1234 N. Street St. City, State 12345"
]
]
}
I saw stuff about your own callback function as a function parameter (or something along those lines) to handle this, but I was completely lost. I also looked at Swift async/await, but I don't know how that works with callback functions. Xcode had the option to refactor user.authentication.do { authentication, error in to let authentication = try await user.authentication.do(), but it threw a missing parameter error (the closure it previously had).
EDIT: user.authentication.do also returns void--another reason the refactor didn't work (I think).
There is probably a much more elegant way to do all of this so excuse the possibly atrocious way I did it.
Here is the link to Google Identity Wrapper info.
Thanks in advance for your help.
Solved my own problem.
It appears (according to Apple's async/await intro video) that when you have an unsupported callback that you need to run asynchronously, you wrap it in something called a Continuation, which allows you to manually resume the function on the thread, whether throwing or returning.
So using that code allows you to run the Google Identity token refresh with async/await.
private static func auth(_ user: GIDGoogleUser) async throws -> GIDAuthentication? {
typealias AuthContinuation = CheckedContinuation<GIDAuthentication?, Error>
return try await withCheckedThrowingContinuation { (continuation: AuthContinuation) in
user.authentication.do { authentication, error in
if let error = error {
continuation.resume(throwing: error)
} else {
continuation.resume(returning: authentication)
}
}
}
}
static func search(user: GIDGoogleUser) async throws {
// some code
guard let authentication = try await auth(user) else { ... }
// some code
}
I then ran that before using Alamofire's built-in async/await functionality for each request (here's one).
let dataTask = AF.request(...).serializingDecodable(NameResponseModel.self)
let response = try await dataTask.value
return response.values[0]
still struggling with this d*** FB SDK :-/
Basically, I've got an app that is supposed to post content to a FB Page. To achieve that, I login using the FB sdk. Then I request authorisations as follow
LoginManager().logIn(permissions: ["pages_manage_posts", "pages_read_engagement", "pages_show_list"], viewController: controller) { result in
print("res \(result)")
switch result {
case .success:
// the pageId is in data>id
Defaults[\.facebookSwitchOn] = true
GraphRequest.init(graphPath: "me/accounts").start { (connexion, result, error) in
guard let result = result as? [String:Any],
let dataArray = result["data"] as? Array<Any>,
let data = dataArray.first as? [String:Any],
let pageId = data["id"] as? String,
let access = data["access_token"] as? String else { return }
print("\(pageId)")
Defaults[\.facebookPageId] = pageId
Defaults[\.facebookPageAccessToken] = access
}
completion(true)
case .failed(let error):
completion(false)
MessageManager.show(.basic(.custom(title: "Oups".local(), message: error.localizedDescription, buttonTitle: nil, configuration: MessageDisplayConfiguration.alert)), in: controller)
default: ()
}
}
I save the pageId and TokenID to be able to perform a POST request as follow
GraphRequest
.init(graphPath: "\(pageId)/photos",
// parameters: ["source" : image, "caption" : text, "access_token" : token, "published" : false],
parameters: ["caption" : contentDescription, "url" : "https://www.cdiscount.com/pdt2/9/2/8/1/700x700/889698377928/rw/figurine-funko-pop-deluxe-game-of-thrones-daen.jpg", "access_token" : token],
httpMethod: .post)
.start { (connexion, result, error) in
completion(Result.success(true))
}
However, I get a weird error telling that publish_actions has been deprecated.
I logged the request using Charles, and here it is https://ibb.co/89wPgKx.
Now here is the debug from the GraphAPI explorer :
curl -i -X POST \ "https://graph.facebook.com/v7.0/104226051340555/photos?caption=test%20message%20from%20Graph%20API%20for%20photo&url=https%3A%2F%2Fwww.cdiscount.com%2Fpdt2%2F9%2F2%2F8%2F1%2F700x700%2F889698377928%2Frw%2Ffigurine-funko-pop-deluxe-game-of-thrones-daen.jpg&access_token=<access token sanitized>"
Basically, it is the same request excepting the fact that parameters in the explorer are URL parameters and they are encapsulated in a json.
I can't understand why the graph explorer request succeeds while the SDK request fails.
I'm totally stuck :-/
Thanks for your help.
I am trying to make a request to Google Cloud NLP API to obtain sentiment analysis for a piece of text. I used Postman to design the correct request, and I was able to get a valid response using Postman. However, when I try to make the same request from Swift, it gives me an error. The error and code snippet used to make the request is shown below.
func sendAPIRequest(with text: String){
print("Text: ", text)
let jsonRequest = [
[
"document":[
"type":"PLAIN_TEXT",
"language": "EN",
"content":"'Lawrence of Arabia' is a highly rated film biography about British Lieutenant T. E. Lawrence. Peter O'Toole plays Lawrence in the film."
],
"encodingType":"UTF8"
]
]
let jsonObject = JSON(jsonRequest)
let headers: HTTPHeaders = [
"X-Ios-Bundle-Identifier": "\(Bundle.main.bundleIdentifier ?? "") ",
"Content-Type": "application/json"
]
let APIRequest = Alamofire.request("https://language.googleapis.com/v1/documents:analyzeSentiment?key=\(gCloudAPIKey)", method: .post , parameters: jsonRequest as? [String: Any], encoding: JSONEncoding.default , headers: headers).responseJSON { (response) in
print(response)
if let json = response.result.value {
print("JSON: \(json)")
}
}
Error:
JSON: {
error = {
code = 400;
details = (
{
"#type" = "type.googleapis.com/google.rpc.BadRequest";
fieldViolations = (
{
description = "Must have some text content to annotate.";
field = "document.content";
}
);
}
);
message = "One of content, or gcs_content_uri must be set.";
status = "INVALID_ARGUMENT";
};
}
Sorry. Solved it. My jsonRequest should be of type Parameters according to Alamofire.
let jsonRequest: Parameters =
[
"document":[
"type":"PLAIN_TEXT",
"language": "EN",
"content":"\(text)"
],
"encodingType":"UTF8"
]
I am trying to implement private 1 to 1 chat with QuickBlox but following the Quickblox docs only shows for group chat in http://quickblox.com/developers/Chat#Create_dialog . When I try sending just single occupants_ids, it gives following error :
{
"errors": [
"Occupants_ids cannot be less than one."
]
}
I am hitting create Dialog API with following body :
{
"type": 3,
"name": "",
"occupant_id": "13822296"
}
Do I need to update some keys in my request body?
Please check: Create new 1-1(private) chat dialog
Code from documentaton work for me:
let chatDialog: QBChatDialog = QBChatDialog(dialogID: nil, type: QBChatDialogType.Private)
chatDialog.occupantIDs = [user.ID]
QBRequest.createDialog(chatDialog, successBlock: {(response: QBResponse?, createdDialog: QBChatDialog?) in completion?(response: response, createdDialog: chatDialog)
print("sucess + \(response)")
}, errorBlock: {(response: QBResponse!) in
print("response + \(response)")
})
QBChatDialog *chatDialog = [[QBChatDialog alloc] initWithDialogID:null type:QBChatDialogTypePrivate];
chatDialog.occupantIDs = #[#(1530190)];
[QBRequest createDialog:chatDialog successBlock:^(QBResponse *response, QBChatDialog *createdDialog) {
} errorBlock:^(QBResponse *response) {
}];
you can use this and you should provide one occupantIds. If it works please let me know.
let user = QBUUser()
user.id = UInt(arrDoctors[sender.tag].QuickBloxId)!
user.fullName = arrDoctors[sender.tag].title.capitalizeFirst
ServicesManager.instance().chatService.createPrivateChatDialog(withOpponent: user) { (response, dialog) in
let chatvc = CHAT_STORYBOARD.instantiateViewController(withIdentifier: "ChatViewController") as! ChatViewController
chatvc.dialog = dialog
self.navigationController?.pushViewController(chatvc, animated: true)
}
So i'm trying to get a users Facebook profile image using SLRequest. I feel like I've scoured the entire internet to no avail and am at my wits end. Here's the dilemma...
Version 1 of the code:
let store = ACAccountStore()
let type = store.accountTypeWithAccountTypeIdentifier(ACAccountTypeIdentifierFacebook)
store.requestAccessToAccountsWithType(type, options: [ ACFacebookAppIdKey: "1437725166510606", ACFacebookPermissionsKey: ["email"] ]) { (granted: Bool, error: NSError!) -> Void in
if granted {
let accounts = store.accountsWithAccountType(type)
if let account = accounts.last as? ACAccount {
let pictureURLString = "https://graph.facebook.com/v2.1/me/picture"
let request = SLRequest(forServiceType: SLServiceTypeFacebook, requestMethod: SLRequestMethod.GET, URL: NSURL(string: pictureURLString), parameters: nil)
request.account = account
request.performRequestWithHandler() { (data: NSData!, response: NSHTTPURLResponse!, error: NSError!) -> Void in
if let imageData = data {
// Save the image
// println("Data size: \(imageData.length)\ndata: \(imageData.description)\nAs string: \(NSString(data: imageData, encoding: NSUTF8StringEncoding))")
data.writeToFile(NSFileManager.defaultManager().profileImagePath(), atomically: true)
}
}
}
}
}
Ok, so this versions works, but returns a really, really small version of the profile image. I want a larger image! According to the Facebook docs, and lot's of others on SO the way to do this is to specify parameters such as: type=large or width=120&height=120 but as soon as I do this I get the following error:
{"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}
When the Facebook docs for getting the profile image (at https://developers.facebook.com/docs/graph-api/reference/v2.1/user/picture) explicitly state:
Because profile pictures are always public on Facebook, this call does
not require any access token.
Many suggestions, such as this answer https://stackoverflow.com/a/7882628/1175289, suggest using the Facebook id rather than "me" in the request, but this does not seem to work at all now that we get an app_scoped_user_id rather than the canonical fbId.
EDIT: This works fine, I was just being a plank! :)
For the sake of sanity, here is the code that causes the error:
let store = ACAccountStore()
let type = store.accountTypeWithAccountTypeIdentifier(ACAccountTypeIdentifierFacebook)
store.requestAccessToAccountsWithType(type, options: [ ACFacebookAppIdKey: "1437725166510606", ACFacebookPermissionsKey: ["email"] ]) { (granted: Bool, error: NSError!) -> Void in
if granted {
let accounts = store.accountsWithAccountType(type)
if let account = accounts.last as? ACAccount {
let pictureURLString = "https://graph.facebook.com/v2.1/me/picture?type=large"
let request = SLRequest(forServiceType: SLServiceTypeFacebook, requestMethod: SLRequestMethod.GET, URL: NSURL(string: pictureURLString), parameters: nil)
request.account = account
request.performRequestWithHandler() { (data: NSData!, response: NSHTTPURLResponse!, error: NSError!) -> Void in
if let imageData = data {
// Save the image
// println("Data size: \(imageData.length)\ndata: \(imageData.description)\nAs string: \(NSString(data: imageData, encoding: NSUTF8StringEncoding))")
data.writeToFile(NSFileManager.defaultManager().profileImagePath(), atomically: true)
}
}
}
}
}
as you can see, the only thing that has changed is the addition of ?type=large to the url string.
If anyone has faced a similar issue, or has any idea what I'm doing wrong, help would be very much appreciated! :)
Because you are using /me/ in your API call, an access_token is required because the API doesn't know who me is. If you replace this with a User ID, e.g.
https://graph.facebook.com/v2.1/4/picture?type=large
It should work fine.
If you want to continue using /me/ in the URL, just append the user's access_token to the URL too, e.g.:
https://graph.facebook.com/v2.1/4/picture?type=large&access_token=abcdef
