一直在看这个great Angular Beginners course但陷入了注册过程。
index.html
<!DOCTYPE html>
<html ng-app="githubViewer">

github.js
(function() {
var github = function($http) { // requires the service $http
// Private implementation details //
var gettingUser = function(username) {
return $http.get("https://api.github.com/users/" + username)
.then(function(response) {
return response.data;
});
/* returning the promise that already comes with
the function to perform the data extration
*/
};
var gettingRepos = function(user) {
return $http.get(user.repos_url)
.then(function(response) {
return response.data;
});
/* returning a promise that it will return the data
- so the controller doesn't have to. */
};
// Public API //
return {
gettingUser: gettingUser,
gettingRepos: gettingRepos
};
// returns an object (github service)
};
var module = angular.module("githubViewer");
/* Not creating a module, just getting the reference
to the one created in script.js So no need to list
the dependencies in a list after githubViewer*/
// Register the Service
module.factory("$github", github);
}());
脚本.js
(function() {
var app = angular.module("githubViewer", []);
var MainController = function(
$scope, $github, $interval, $log,
$anchorScroll, $location) {
var onUserComplete = function(data) {
$scope.user = data;
$github.gettingRepos($scope.user)
.then(onRepos, onError);
};
var onRepos = function(data){
$scope.repos = data;
$anchorScroll( $location.hash("userDetails") );
}
var onError = function(reason) {
$scope.error = "Could not fetch data";
};
var decrementCountdown = function(){
$scope.countdown -= 1;
if($scope.countdown < 1){
$scope.search($scope.username);
}
}
$scope.search = function(username) {
$log.info("Searching for "+ username);
$github.gettingUser(username).then(onUserComplete, onError);
if(countdownIntervalObj){
$interval.cancel(countdownIntervalObj);
$scope.countdown = null;
}
};
var countdownInterval = null;
var startCountdown = function(){
countdownIntervalObj = $interval(decrementCountdown, 1000, $scope.countdown);
}
$scope.username = "angular";
$scope.message = "GitHub Viewer";
$scope.repoSortOrder = "-stargazers_count";
$scope.countdown = 5;
startCountdown();
};
app.controller("MainController",
["$scope", "$http", "$interval", "$log", "$anchorScroll", "$location", "$github", MainController]);
}());
控制台一直说$github.gettingUser
不是一个函数。我做错了什么?
最佳答案
当您注入(inject)依赖项时请注意顺序,因为您注入(inject)了七个依赖项,但只是以错误的顺序将六个传递给了 Controller 。您需要传递 $http
并将 $github
放在最后。
var MainController = function($scope, $http, $interval, $log, $anchorScroll, $location, $github)
app.controller("MainController", ["$scope", "$http", "$interval", "$log", "$anchorScroll", "$location", "$github", MainController]);
