Angular6http发布请求以及x-www-form-urlencoded数据

我试图从端点获取oauth令牌，但我可以说很难找到有效的答案。

下面是我如何使其在Angular 7中工作，但在Angular 6中也将工作

import {HttpClient, HttpHeaders, HttpParams} from '@angular/common/http';

    login(user: string, password: string) {
        const params = new HttpParams({
          fromObject: {
            grant_type: 'password',
            username: user,
            password: password,
            scope: 'if no scope just delete this line',
          }
        });

        const httpOptiOns= {
          headers: new HttpHeaders({
            'Content-Type': 'application/x-www-form-urlencoded',
            'Authorization': 'Basic ' + btoa('yourClientId' + ':' + 'yourClientSecret')
          })
        };

        this.http.post('/oauth', params, httpOptions)
          .subscribe(
            (res: any) => {
              console.log(res);
              sessionStorage.setItem('access_token', res.access_token);
              sessionStorage.setItem('refresh_token', res.refresh_token);
            },
            err => console.log(err)
          );
      }

如果出现cors错误，只需设置一个角度代理：

//proxy.conf.json
{
  "/oauth": {
    "target": "URL TO TOKEN ENDPOINT",
    "changeOrigin": true,
    "secure": false,
    "logLevel": "debug",
    "pathRewrite": {
      "^/oauth": ""
    }
  }
}

您无需JSON.stringify(formData)仅将formData用作方法的第二个参数http.post。

创建的实例FormData。然后附加您需要使用发送的值formData.append()。

而httpHeaders喜欢这个。

const httpOptiOns= {
  headers: new HttpHeaders({
    'Content-Type':  'application/x-www-form-urlencoded'
  })};

const formData = new FormData();
formData.append('username', username);
formData.append('password', password);
formData.append('grant_type', 'password');

this.http.post(apiUrl,formData,httpOptions)
                    .subscribe(
                        (res) => {
                            console.log(res);
                        },
                        err => console.log(err)
                    );
