我使用angular2和打字稿。
我试图发布到我的邮件黑猩猩订阅列表。
到目前为止我的代码:
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;
});
}
这是我在控制台中遇到的错误:
我现在收到此错误:未捕获的SyntaxError:意外的标记<
以下当前代码:
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
标题应该出现在响应中,而不是在请求中。
如果您的服务支持CORS,则必须在响应标头中将其返回以允许请求。所以这不是你的Angular应用程序的问题,但它必须在服务器端级别处理......

修改强>
似乎thepoolcover.us10.list-manage.com
不支持CORS而是支持JSONP。您可以尝试重构代码,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JSONP_PROVIDERS
函数时,请不要忘记指定bootstrap
。

问题出在服务器端。您必须告诉您的服务接受GET请求。例如,在使用Spring的JEE中,您需要添加:
@CrossOrigin
@RequestMapping(value = "/something", method = RequestMethod.GET)
