Aurelia:配置获取客户端 [英] Aurelia: configure fetch client

问题描述

我使用Aurelia的获取客户端与服务器进行通信.在每个使用fetch客户端的viewModel中，我必须将其配置为使用拦截器发送自定义标头(令牌)的客户端.

I use Aurelia's fetch client to communicate with my server. In every viewModel using the fetch client I have to configure it the client to use an interceptor to send a custom header(a token).

有没有一种方法可以在某处配置一次获取客户端，而不是在每个viewModel中重写拦截器代码.

Is there a way to configure the fetch client once somewhere instead of rewriting the interceptor code in each viewModel.

推荐答案

您可以将配置放入 main.js 文件中.像这样:

You could put the configuration in the main.js file. Like this:

...
aurelia.use
  .standardConfiguration()
  .developmentLogging();

let container = aurelia.container;

let http = new HttpClient();
http.configure(config => {
  config
  .useStandardConfiguration()
  .withBaseUrl('http://localhost:8080/api/')
  .withDefaults({
     headers: {
       'Authorization': tokenVariable // <---- your magic here
     }
  })
  .withInterceptor({
    request(request) {
      console.log(`Requesting ${request.method} ${request.url}`);
      return request;
    },
    response(response) {
      console.log(`Received ${response.status} ${response.url}`);
    }
  });
});

container.registerInstance(HttpClient, http);

现在，您只需要注入HttpClient即可获得上面配置的实例.

Now, you just have to inject the HttpClient to get the instance configured above.

@inject(HttpClient)
export class MyViewModel {
}
