我有一个项目,我成功地从 TypeScript(Angular HTTP 服务)代码到 Web API Controller 发出 Http Get 请求,并在网格中显示列表。该项目成功使用 Angular JS 1.4.x 和 TypeScript。
完整项目的 GitHub URL . 下面是调用服务器的 TypeScript 代码。
module App {
export class StudentListService {
private qService: ng.IQService;
private httpService: ng.IHttpService;
constructor($q: ng.IQService, $http: ng.IHttpService) {
this.qService = $q;
this.httpService = $http;
}
get(): ng.IPromise<Object[]> {
var self = this;
var deffered = self.qService.defer();
self.httpService.get('/api/values').then((result: any): void => {
if (result.status === 200) {
deffered.resolve(result.data);
} else {
deffered.reject(result);
}
}, error => {
deffered.reject(error);
});
return deffered.promise;
}
}
StudentListService.$inject = ['$q', '$http'];
angular.module('app').service('StudentListService', StudentListService);
}
现在,我想通过 get 请求调用添加自定义 header 。我尝试了很多方法,但 TypeScript 一直给我构建错误。任何帮助或解决方法将不胜感激。
最佳答案
只要您使用正确的 Angular 输入文件,您就应该能够将 header 添加为配置的一部分,第二个参数的类型为 ng.IRequestShortcutConfig
这是 IHttpProviderDefaults
的扩展有 header
属性(property)。
get<T>(url: string, config?: IRequestShortcutConfig): IHttpPromise<T>;
还添加了很多简化的代码。
export class StudentListService {
static $inject = ['$q', '$http'];
constructor(private qService: angular.IQService,
private httpService: angular.IHttpService) { }
get(): angular.IPromise<Object[]> {
//Example of config structure
var config: angular.IRequestShortcutConfig = {
headers: {
"someheader":"somevalue"
}
}
//add config and just return the promise directly instead of creating a deferred object. Promises are chainable
return this.httpService.get('/api/values', config)
.then((result: any) => result.data);
//If you want to catch then use ".catch" instead of second argument to the "then" which is a better practice as any error that may happen inside your code in the then block will be caught as well.
}
}
关于javascript - Angular JS TypeScript IHttpService 注入(inject)自定义 header 值,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/33281984/
