Angular - OpenApi CodeGen - 如何在 api 请求中添加 header ？

Question

我正在使用 Angular 10。我正在使用 openapi codegen(自动生成)服务。

问题:我想在我的 header 中传递 Authorization: Token 123456 但似乎无法理解如何以及在何处添加拦截器。

我的组件文件是:

 constructor(        
    private meApi : MeService
    )


 meDetails;
  meCheck(){
      this.meApi.meRead().subscribe(
        (data: any) => {
          this.meDetails= data;
        },
        (err) => { console.error(err); },
        () => { }
      )
    }

在 ngOnInIt 中运行这个函数。我收到以下错误:

401 (Unauthorized)

因为很明显，授权 token 没有通过 API 传递。

自动生成的服务文件中的meRead()函数有如下相关代码:

 /**
     * @param observe set whether or not to return the data Observable as the body, response or events. defaults to returning the body.
     * @param reportProgress flag to report request and response progress.
     */
    public meRead(observe?: 'body', reportProgress?: boolean, options?: {httpHeaderAccept?: 'application/json'}): Observable<User>;
    public meRead(observe?: 'response', reportProgress?: boolean, options?: {httpHeaderAccept?: 'application/json'}): Observable<HttpResponse<User>>;
    public meRead(observe?: 'events', reportProgress?: boolean, options?: {httpHeaderAccept?: 'application/json'}): Observable<HttpEvent<User>>;
    public meRead(observe: any = 'body', reportProgress: boolean = false, options?: {httpHeaderAccept?: 'application/json'}): Observable<any> {

        let headers = this.defaultHeaders;

        // authentication (DRF Token) required
        if (this.configuration.apiKeys) {
            const key: string | undefined = this.configuration.apiKeys["DRF Token"] || this.configuration.apiKeys["Authorization"];
            if (key) {
                headers = headers.set('Authorization', key);
            }
        }

        let httpHeaderAcceptSelected: string | undefined = options && options.httpHeaderAccept;
        if (httpHeaderAcceptSelected === undefined) {
            // to determine the Accept header
            const httpHeaderAccepts: string[] = [
                'application/json'
            ];
            httpHeaderAcceptSelected = this.configuration.selectHeaderAccept(httpHeaderAccepts);
        }
        if (httpHeaderAcceptSelected !== undefined) {
            headers = headers.set('Accept', httpHeaderAcceptSelected);
        }

如何在此请求的 header 中传递授权: token 12345？

总结:如何在openapi codegen服务文件中传递Authorization header？

如能详细解答，将不胜感激。谢谢。

Answer 1

您可以通过更改生成的客户端的 defaultHeaders 属性来传递 header ，或者也可以通过在 ad-hoc 属性中提供一些配置来传递 header 。 看这个blog post对于其他一些选项。

/**
 * OpenAPI definition [...]
 */
import { ...}


@Injectable({
  providedIn: 'root'
})
export class UserControllerService {

    protected basePath = 'http://localhost:8081';
    public defaultHeaders = new HttpHeaders(); // <- here
    public configuration = new Configuration(); // <- or there
    public encoder: HttpParameterCodec;
    
    {...}
}

至于通过方法调用的{httpHeaders: '/'}传递一些有用的东西，没看懂怎么办。
