如何使用 Express 服务器对 api.github 进行 GET 调用 [英] How to make a GET call to api.github with Express server

问题描述

我被屏蔽了 3 天，并在互联网上进行了研究.这是代码.

I'm blocked since 3 days and did my research on the internet. Here' is the code.

api.js

const express = require('express');
const router = express.Router();
var http = require('http');
var https = require("https");

router.get('/github', async function (req, res) {
    https.get('https://api.github.com/v3/users/tmtanzeel', function (apiRes) {
        apiRes.pipe(res);

    }).on('error', (e) => {
        console.error(e);
        res.status(500).send('Something went wrong');
    });
});

输出:

管理规则禁止请求.请确保您的请求具有 User-Agent 标头 (http://developer.github.com/v3/#user-agent-required).检查 https://developer.github.com 以了解其他可能的原因.

Request forbidden by administrative rules. Please make sure your request has a User-Agent header (http://developer.github.com/v3/#user-agent-required). Check https://developer.github.com for other possible causes.

我在这里发现了一些有用的东西:

I found something useful here:

1. 在 Node.js/Express 中，我如何自动将此标头添加到每个渲染"中?回应?
2. 正在请求 https://api.github.com/users (api) 返回 System.Net.HttpStatusCode.Forbidden IsSuccessStatusCode = false

但这些都不是很有帮助.

But these were not very helpful.

我试过:res.setHeader("User-Agent","My App"); 但我不太确定第二个参数.

I tried: res.setHeader("User-Agent", "My App"); but I'm not very sure about the second argument.

修改了server.js

const express = require('express');
const app = express();
const api = require('./routes/api');
const cors = require('cors');
app.use(cors());

app.use(function (req, res, next) {

    // Website you wish to allow to connect
    res.setHeader('Access-Control-Allow-Origin', '*');

    // Request methods you wish to allow
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

    // Request headers you wish to allow
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');

    // Set to true if you need the website to include cookies in the requests sent
    // to the API (e.g. in case you use sessions)
    res.setHeader('Access-Control-Allow-Credentials', true);

    res.setHeader("User-Agent", "My App"); // <-------------ADDED HEADER HERE

    // Pass to next layer of middleware
    next();
});

app.use('/api', api);
app.get('/', function (req, res) {
    res.send('Server is up and running!');
})

app.listen(3000, function () {
    console.log('Server listening on 3000 port');
});

你有没有遇到过这样的问题.请帮忙.

Have you ever face this kind of issue. Please help.

推荐答案

您正在为响应设置标题.相反，您必须在您进行的 API 调用中设置标头.您可以将 options 对象传递给 http.get() 方法并在那里设置标题.

You are setting headers to your response. Instead, you must set headers in the API call you make. You can pass options object to the http.get() method and set headers there.

router.get('/github', async function (req, res) {

    const options = {
       hostname: 'api.github.com',
       path: '/v3/users/tmtanzeel',
       headers: {
           'User-Agent' : 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1521.3 Safari/537.36'
       }
    }

    https.get(options, function (apiRes) {
        apiRes.pipe(res);

    }).on('error', (e) => {
        console.error(e);
        res.status(500).send('Something went wrong');
    });
});
