我需要在oAuth2身份验证服务器中发出请求。
我可以在邮递员中提出请求并获得令牌,不能从角度4发出相同的请求。
我的CORS配置良好,因为其他请求工作正常。
以下是HTTP请求的详细信息。
POST /oauth/token HTTP/1.1
Host: localhost:8080
Authorization: Basic YXBwbGljYXRpb246c2VjcmV0
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache
Postman-Token: 9f9582e9-fe73-499f-d7f7-82498a974e39
grant_type=password&username=pedroetb&password=password
在角度4中,我试过这种方式
let headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
headers.append("Authorization","Basic YXBwbGljYXRpb246c2VjcmV0");
var obtainTokenUrl = 'http://localhost:8080/oauth/token';
this._http.post(obtainTokenUrl + "?grant_type=password&username=pedroetb&password=password", null, {headers: headers}).subscribe(response => {
console.log(response);
});
但这不起作用。
那么如何从角度4发出同样的请求呢?

这是我检索用户数据的简单代码。请参阅,标题以标题选项的形式给出。您可以在docs
中查看更多内容createUser(user: User): Observable<User> {
const submittedUser = JSON.stringify(user); // user is form-submitted data object
const headers = new Headers ({ 'Content-Type': 'application/json' });
const options = new RequestOptions({headers: headers});
return this.http.post(baseURL + 'user/create', submittedUser, options)
.map((response: Response) => {this.processHttpmsgService.extractData(response);})
.catch(error=> Observable.throw(error));
}

PostRequest(url:string,data:any){
var headers = new Headers();
let req = JSON.stringify(data);
this.onRequest("request: " + url + "data: " + req);
headers.append ("content-Type","application/json");
headers.append("charset","utf-8;");
headers.append("Access-Control-Allow-Origin", "*");
var token = localStorage.getItem('token');
headers.append("Authorization","Bearer "+ token);
let options = new RequestOptions({ headers: headers });
console.log(options);
// don't have the data yet
return new Promise(resolve => {
this.http.post(url,req,options)
.map(res => res.json())
.subscribe(data => {
resolve(data);
this.onSuccess(data);
}
,error => {
this.onError(error);
}
);
});
}
也不要忘记导入 从&#39; @ angular / http&#39;;
导入{Http,Headers,RequestOptions}
