我使用Typescript创建了一个服务：
class ConfigService implements IConfigService {
public admin = {};
public adminBackup = {};
public user = {};
public loaded = false;
constructor(
private $http: ng.IHttpService,private $q: ng.IQService
) {
}
static $inject = [
'$http','$q'
];
put = ():ng.IHttpPromise<> => {
var defer = this.$q.defer();
if (angular.equals(this.admin,this.adminBackup)) {
return defer.resolve();
} else {
this.$http({
data: {
adminJSON: JSON.stringify(this.admin),userJSON: JSON.stringify(this.user)
},url: '/api/Config/Put',method: "PUT"
})
.success(function (data) {
this.adminBackup = angular.copy(this.admin);
this.userBackup = angular.copy(this.user)
return defer.resolve();
});
}
return defer.promise;
};
}
我也创建了这个界面：
interface IConfigService {
put(): ng.IHttpPromise<>;
}
Error 3 Cannot convert 'void' to 'ng.IHttpPromise<any>'.
Error 4 Cannot convert 'ng.IPromise<{}>' to 'ng.IHttpPromise<any>':
Type 'ng.IPromise<{}>' is missing property 'success' from type 'ng.IHttpPromise<any>'.
使用
ng.IPromise<void>
另外,如果您不声明返回类型并且不使用该接口,那么您可以隐式地为其输入.
这里也不应该有返回语句：
return defer.resolve();
只是：
defer.resolve();
