隨着Parse宣佈退休，我將Parse Server遷移到了Heroku上。有了我對Heroku的新手知識，我不知道他們是否具有與雲代碼類似的功能，但我知道幾個月前Parse Introduced a Heroku + Parse功能允許您在任何node.js環境中運行Cloud Code，特別是Heroku的。如何在Heroku上運行雲碼？
我的困境是，我已經將我的服務器從分析遷移到Heroku，然後才瞭解此功能：/，所以我無法從終端運行任何解析雲代碼，因爲現在沒有現有的服務器了。所以問題是，我如何在Heroku中模仿以下雲代碼&如何調整我的swift？
雲代碼：
// Use Parse.Cloud.define to define as many cloud functions as you want.
// For example:
Parse.Cloud.define("isLoginRedundant", function(request, response) {
Parse.Cloud.useMasterKey();
var sessionQuery = new Parse.Query(Parse.Session);
sessionQuery.equalTo("user", request.user);
sessionQuery.find().then(function(sessions) {
response.success({ isRedundant: sessions.length>1 });
}, function(error) {
response.error(error);
});
});
這裏是我迅速回在Xcode：
PFUser.logInWithUsernameInBackground(userName!, password: passWord!) {
(user, error) -> Void in
if (user != nil) {
// don't do the segue until we know it's unique login
// pass no params to the cloud in swift (not sure if [] is the way to say that)
PFCloud.callFunctionInBackground("isLoginRedundant", withParameters: [:]) {
(response: AnyObject?, error: NSError?) -> Void in
let dictionary = response as! [String:Bool]
var isRedundant : Bool
isRedundant = dictionary["isRedundant"]!
if (isRedundant) {
// I think you can adequately undo everything about the login by logging out
PFUser.logOutInBackgroundWithBlock() { (error: NSError?) -> Void in
// update the UI to say, login rejected because you're logged in elsewhere
// maybe do a segue here?
let redundantSession: String = "you are already logged in on another device"
self.failedMessage(redundantSession)
self.activityIND.stopAnimating()
self.loginSecond.userInteractionEnabled = true
}
} else {
// good login and non-redundant, do the segue
self.performSegueWithIdentifier("loginSuccess", sender: self)
}
}
} else {
// login failed for typical reasons, update the UI
dispatch_async(dispatch_get_main_queue()) {
self.activityIND.stopAnimating()
self.loginSecond.userInteractionEnabled = true
if let message = error?.userInfo["error"] as? String
where message == "invalid login parameters" {
let localizedMessage = NSLocalizedString(message, comment: "Something isn't right, check the username and password fields and try again")
print(localizedMessage)
self.failedMessage(localizedMessage)
}else if let secondMessage = error?.userInfo["error"] as? String
where secondMessage == "The Internet connection appears to be offline." {
self.failedMessage(secondMessage)
}
}
}
}
