如标题所述,我想在没有预检选项的情况下发出一个简单的GET请求,因为服务器不响应“ Access-Control-Allow-Origin”标头,并且我无法更改这些服务器设置
我的代码很简单:
export interface HttpOptions {
headers?: HttpHeaders;
params?: HttpParams;
observe?: 'body';
}
private getProfileDetails() {
const httpOptions: HttpOptions = {
headers: new HttpHeaders({
'Content-Type': 'text/plain'
}),
params: new HttpParams()
.set('service', 'http%3A%2F%2Flocalhost%3A4200')
.append('ticket', this.currentTicket)
};
this.http.get('https://server.address/val', httpOptions).subscribe(data => {
console.log(data);
});
}
由于某种原因,浏览器不断出现错误:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.
据我了解,这应该是一个简单的GET请求,它不需要OPTIONS,所以我对操作方法有些困惑。
任何提示将不胜感激。

您将需要探索为API请求设置angular-cli代理。
