角度休息api调用返回https状态码401，需要身份验证

Question

I am hitting an api for getting userinfo, for that I am passing header authorization with value, but in options method it is firing and giving error that https status code 401, authentication required.

I am trying the same with Chrome browser and Postman client tool then it's giving me desired result. Why only my app is throwing such error? It's supposed to give me result if I am giving authorization header for that.

For instance, code is like:

this.http.get(this.url,{headers:this.headers});

Answer 1

Try setting withCredentials : true .

Here is my Working Code. Hope it helps. Also note Iam using new httpclient of Angular 5.

emailsignin(username: string, password: string) { .
    let url = this.backendUrl + "/index";   
    let params = 'username='+username+'&password='+password;
    let httpheaders = new HttpHeaders(
        {
        'Content-Type': 'application/x-www-form-urlencoded'
        });

    return this._httpclient.post(url, params, {headers: httpheaders, withCredentials : true});

}

You should define your options as a RequestOptions object:

let options = new RequestOptions({ headers: new Headers({ 'Authorization': 'Basic xxxx' }) });
this.http.get(this.url,options );
