angularjs – 具有Access-Control-Allow-Origin的Angular 2 http请求设置为*

前端之家收集整理的这篇文章主要介绍了angularjs – 具有Access-Control-Allow-Origin的Angular 2 http请求设置为*前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我使用angular2和typescript。

我试图发布到我的邮件黑猩猩订阅列表。

我的代码到目前为止

constructor(router: Router,http: Http){   
      this.router = router;

      this.http = http; 
      this.headers = new Headers();
      this.headers.append('Content-Type','application/json');
      this.headers.append('Access-Control-Allow-Origin','*');
  }

  subscribe = () => {
        var url = "https://thepoolcover.us10.list-manage.com/subscribe/post?u=b0c935d6f51c1f7aaf1edd8ff&id=9d740459d3&subscribe=Subscribe&EMAIL=" + this.email;
        this.isSuccess = false;

        this.http.request(url,this.headers).subscribe(response => {
           console.log(response);
           this.isSuccess = true; 
        });   
  }

这是我在控制台中出现的错误

我现在得到这个错误:未捕获的SyntaxError:意外的标记< 当前代码如下:

export class Footer{
  email: string = "";
  router : Router;
  http : Http;
  jsonp: Jsonp;
  isSuccess: boolean = false;

  constructor(router: Router,jsonp: Jsonp,http: Http){   
      this.router = router;
      this.http = http; 
      this.jsonp = jsonp;
  }

  subscribe = () => {
        var url = "https://thepoolcover.us10.list-manage.com/subscribe/post?u=b0c935d6f51c1f7aaf1edd8ff&id=9d740459d3&subscribe=Subscribe&EMAIL=" + this.email;
        this.isSuccess = false;

        this.jsonp.request(url).subscribe(response => {
           console.log(response);
           this.isSuccess = true; 
        });   
  }
Access-Control-Allow-Origin标头是响应中应该存在的,而不是在请求中。

如果您的服务支持CORS,它必须在响应头中返回以允许该请求。所以这不是您的Angular应用程序的问题,但它是必须在服务器端级别处理的东西…

编辑

似乎thepoolcover.us10.list-manage.com不支持CORS而是JSONP。您可以尝试重构您的代码,如下所述:

constructor(private router: Router,private jsonp: Jsonp){   
}

subscribe = () => {
  var url = "https://thepoolcover.us10.list-manage.com/subscribe/post?u=b0c935d6f51c1f7aaf1edd8ff&id=9d740459d3&subscribe=Subscribe&EMAIL=" + this.email;
  this.isSuccess = false;

  this.jsonp.request(url,this.headers).subscribe(response => {
    console.log(response);
    this.isSuccess = true; 
  });   
}

调用引导函数时不要忘记指定JSONP_PROVIDERS。
