我在我的服务中定义了以下get请求：
createAuthorizationHeader(user, pass) {
let headers: HttpHeaders = new HttpHeaders;
headers = headers.append('Accept', 'application/json, text/plain, */*');
headers = headers.append('Authorization', 'Basic ' + btoa(user + ':' + pass));
headers = headers.append('Content-Type', 'application/json; charset=utf-8');
console.log(headers);
return this.http.get(this._loginUrl, {
headers: headers
});
}
结果是：
OPTIONS https://localhost:8443/delivery/all 401 ()
Failed to load https://localhost:8443/delivery/all: Response for preflight does not have HTTP ok status.
HttpErrorResponse {headers: HttpHeaders, status: 0, statusText: "Unknown Error", url: null, ok: false, …}
我也和Postman做了相同的帖子请求，但一切正常，所以本地服务器工作。
我无法弄清楚我的要求是怎么回事。
