最后一个链式承诺没有运行 [英] The last chained promise does not run
问题描述
我已经链接了一些我想按特定顺序执行的方法.第二个方法 deviseLogin()
返回一个 URL,该 URL 应该传递给下一个方法 redirect(url)
I have chained a few methods that I'd like to execute in that specific order.
The second method deviseLogin()
returns a URL that should be passed on the the next method redirect(url)
第一个和第二个方法运行,但我从来没有听到最后一个redirect(url)
的任何消息.你能看出我做错了什么吗?
The first and the second method runs, but I never hear anything from the last redirect(url)
. Can you see what I'm doing wrong?
getUserToken = (username, password) ->
console.log "I'm first"
$http(
method: "POST"
url: "/oauth/token"
params: params
).success((data, status, headers, config) ->
$scope.$storage.token = data.access_token
defer = $q.defer()
$scope.signIn = (data) ->
defer.promise
.then( getUserToken($scope.email, $scope.password) )
.then( deviseLogin() )
.then( redirect(url) )
redirect = (url) ->
console.log "I'm last"
console.log "will redirect to #{url}"
$window.location = data.url
deviseLogin = () ->
console.log "I'm second"
$scope.authErrors = []
authData = { user: { email: $scope.email, password: $scope.password }}
$http(
# Perform a regular Devise login
method: "POST"
url: "/users/sign_in"
data: authData
)
.success (data) ->
# I can see the log lines below and data.url is what I expect it to be
console.log "logged in devise"
console.log "data.url: #{data.url}"
data.url
推荐答案
I never got the last .then( redirect(url) )
启动.通过移动 redirect 解决了问题(url)
到 deviseLogin()
上的 success() 内.
I never got the last .then( redirect(url) )
to kick in. Solved the problem by moving redirect(url)
to within success() on deviseLogin()
.
