错误：[$ injector：unpr]
问题描述：
我正在Angular Js工作。我正在尝试根据用户名和密码从Sql数据库创建一个登录系统。我输入了正确的用户名和密码，但是这并没有进入页面我想重定向用户主页，但我不能这样做。当我提交的用户名和密码的文本框从控制台应用程序我得到了以下错误....
angular.min.js:123 Error: [$injector:unpr] http://errors.angularjs.org/1.6.5/$injector/unpr?p0=myServiceProvider%20%3C-%20myService%20%3C-%20myCntrl

这是我Module.Js代码...
var app = angular.module("myApp", [])
.controller("myCntrl", function ($scope, myService) {
$scope.LoginCheck = function() {
var User = {
UserName: $scope.uName,
Password: $scope.password
};
$("#divLoading").show();
var getData = myService.UserLogin(User);
getData.then(function (msg) {
if (msg.data == "0") {
$("#divLoading").hide();
$("#alertModal").modal('show');
$scope.msg = "Password Incorrect !";
}
else if (msg.data == "-1") {
$("#divLoading").hide();
$("#alertModal").modal('show');
$scope.msg = "Username Incorrect !";
}
else {
uID = msg.data;
$("#divLoading").hide();
window.location.href = "/Home/Index";
}
});
debugger;
}
function clearFields() {
$scope.uName = '';
$scope.uPwd = '';
}
//move this function inside `myCntrl` controller function.
$scope.alertmsg = function() {
$("#alertModal").modal('hide');
};
});
app.service("myService", function ($http) {
this.UserLogin = function (User) {
var response = $http({
method: "post",
url: "/Login/Login",
data: JSON.stringify(User),
dataType: "json"
});
return response;
}
});
这里是登录控制器代码..
public class LoginController : Controller
{// GET: /Login/
public ActionResult Login()
{
return View();
}
[HttpPost]
public string Login(UserLogin data)
{
bool isPasswordCorrect = false;
string un = data.UserName;
string Password = data.Password;
using (HalifaxDatabaseEntities entity = new HalifaxDatabaseEntities())
{
var user = entity.UserLogins.Where(u => u.UserName == un).FirstOrDefault();
if (user != null)
{
if (Password == user.Password)
{
Session["LoginID"] = user.ID;
Session["Username"] = user.Firstname + ' ' + user.Lastname;
return user.ID.ToString();
}
else
{
return "0";
}
}
else
{
return "-1";
}
}
}
}
}
这里是我的html代码....

答
您已经声明alertmsg外控制器功能的截屏。将其移动到myCntrl控制器工厂功能中。所以基本上因为$scope.alertmsg功能保存在$scope以外的变量没有定义，这就是为什么JS编译器大喊大叫。并且进一步的声明不会被执行。由于myService服务没有得到myApp角module注册并说myService unknown provider
http://errors.angularjs.org/1.6.5/ $injector/unpr?p0=myServiceProvider%20%3C-%20myService
var app = angular.module("myApp", [])
.controller("myCntrl", function ($scope, myService) {
$scope.LoginCheck = function() {
//code as is
}
function clearFields() {
$scope.uName = '';
$scope.uPwd = '';
}
//move this function inside `myCntrl` controller function.
$scope.alertmsg = function() {
$("#alertModal").modal('hide');
};
});
Apart from angularjs errors, you have fix all the error appearing in console. Likewise load
jQuerybeforebootstrap.js
为myService定义内的script.js文件 – Rasel
我做到了，但遗憾的说还是同样的结果 – Rasel
