自定义标头问题 (CORS)

Question

我使用 Angular 10（前端）和 Node.js（后端）制作了 Web 应用程序。但是当我通过添加标头发送请求时，它不起作用。 （关闭 CORS 并在 Chrome 上发送请求时有效） 我被发现在 StackOverflow 上缺少一些类似的答案，但不幸的是，这些对我不起作用：|

我发送请求如下，

getAllSubmissions() {
    let token = sessionStorage.getItem('auth-token');
    let path = this.globe.base_path + 'get-submissions';
    this.http.get<any>(path, {headers:{'Access-Control-Allow-Origin':'*', 'auth-token':token}}).toPromise().then(data => {
      this.allsubmissoinsFiltered = data.filter(sub => sub.status != 'active')
      this.allSubmissionsCount = this.allsubmissoinsFiltered.length;
    }).catch(err => {
      console.log(err)
    })
  }

以及，我也在尝试以下代码，

getAllSubmissions() {
    let token = sessionStorage.getItem('auth-token');
    var header = { headers: new HttpHeaders().set('auth-token', token) }
    let path = this.globe.base_path + 'get-submissions';
    this.http.get<any>(path, header).toPromise().then(data => {
      this.allsubmissoinsFiltered = data.filter(sub => sub.status != 'active')
      this.allSubmissionsCount = this.allsubmissoinsFiltered.length;
    }).catch(err => {
      console.log(err)
    })
  }

这两种类型都不能正常工作。

我该如何解决这个问题？希望等待您的宝贵回复！

Answer 1

试试下面的代码，

getAllSubmissions() {
    let token = sessionStorage.getItem('auth-token');
    var header = { headers: new HttpHeaders().set('Authorization', token) }
    let path = this.globe.base_path + 'get-submissions';
    this.http.get<any>(path, header).toPromise().then(data => {
      this.allsubmissoinsFiltered = data.filter(sub => sub.status != 'active')
      this.allSubmissionsCount = this.allsubmissoinsFiltered.length;
    }).catch(err => {
      console.log(err)
    })
  }

这将起作用。
