aurelia-fetch-client

Question

我正在使用 aurelia-fetch-client，当我向我的 nodejs 后端发送请求时出现此错误 api:

Warning: a promise was rejected with a non-error: [object Response]
    at http://localhost:9000/scripts/vendor-bundle.js:39700:20

一切正常，但这个警告非常烦人，我不知道如何修复它，这是发送请求的代码：

import {HttpClient, json} from 'aurelia-fetch-client';
import baseConfig from 'config';

export class AuthService {
    constructor() {
        this.http = new HttpClient().configure(config => {
            config
                .withBaseUrl(baseConfig.baseUrl)
                .useStandardConfiguration();
        });

        this.isAuthenticated = false;
    }

    login(credentials) {
        return this.http.fetch('/login', {
            method: 'post',
            body: json(credentials)
        })
            .then(res => {
                this.saveToken(res.token)
                return Promise.resolve();
            });
    }

    saveToken(token) {
        localStorage.setItem('token', token);
        this.isAuthenticated = true;
    }
}

感谢任何帮助

aurelia-fetch-client 标准配置（通过 .useStandardConfiguration() 在您的代码中应用）拒绝不成功的 HTTP 响应状态代码。在 aurelia/fetch-client 回购 here 中有一个最近（已关闭）的问题。 fetch 客户端拒绝响应本身的承诺，因此浏览器抱怨（它希望承诺只被错误实例拒绝）。

我通过删除 .useStandardConfiguration() 在我自己的代码中解决了这个问题，因为我在这个特定项目中不需要它。您可以查看 the source code 以详细了解配置情况。
