node.js - aurelia-fetch-client-一个 promise 被拒绝，并且没有错误: [object Response]

我正在使用aurelia-fetch-client，当我向nodejs后端api发送请求时收到此错误:

Warning: a promise was rejected with a non-error: [object Response]

一切正常，但是此警告非常令人讨厌，我不知道如何解决它，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;
    }
}

任何帮助表示赞赏

最佳答案

aurelia-fetch-client标准配置(通过.useStandardConfiguration()在您的代码中应用)拒绝非成功的HTTP响应状态代码。 aurelia/fetch-client repo here中有一个与此相关的近期(关闭)问题。获取客户端拒绝响应本身的 promise ，因此浏览器提示(它希望仅在Error实例的情况下拒绝 promise )。

我通过删除.useStandardConfiguration()在我自己的代码中解决了此问题，因为在此特定项目中不需要它。您可以 checkout the source code以获得有关配置情况的更多图片。
