aurelia-fetch-client -一个承诺被拒绝，没有错误:[object Response]

Question

我正在使用aurelia-fetch-client，当我向我的nodejs后端api发送请求时，我得到了这个错误:

Warning: a promise was rejected with a non-error: [object Response]
    at http://localhost:9000/scripts/vendor-bundle.js:39700:20
    at Array.reduce (native)
    at applyInterceptors (http://localhost:9000/scripts/vendor-bundle.js:39696:33)

    at HTMLDocument.handleDelegatedEvent (http://localhost:9000/scripts/vendor-bundle.js:25721:11)

一切正常，但这个警告是非常恼人的，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;
    }
}

感谢您的帮助

aurelia-fetch-client标准配置(通过.useStandardConfiguration()应用于您的代码中)拒绝非成功HTTP响应状态码。在aurelia/fetch-client repo中有一个最近的(关闭的)问题。取回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，因为我在这个特定的项目中不需要它。您可以查看源代码，以获得有关配置过程的更多信息。
