node.js - 使用 Request 的请求函数时，Github API 以 403 响应

Question

我正在尝试向 github 的 API 发出请求。这是我的要求:

var url = 'https://api.github.com/' + requestUrl + '/' + repo + '/';

request(url, function(err, res, body) {
    if (!err && res.statusCode == 200) {

        var link = "https://github.com/" + repo;
        opener(link);
        process.exit();

    } else {
        console.log(res.body);
        console.log(err);
        console.log('This ' + person + ' does not exist');
        process.exit();
    }

});

这是我得到的回复:

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.

我过去曾使用过完全相同的代码，并且有效。请求未抛出任何错误。现在我很困惑为什么我会收到 403(禁止访问)？有什么解决办法吗？

如 URL given in the response 中所述，对 GitHub 的 API 的请求现在需要一个 User-Agent header :

All API requests MUST include a valid User-Agent header. Requests with no User-Agent header will be rejected. We request that you use your GitHub username, or the name of your application, for the User-Agent header value. This allows us to contact you if there are problems.

请求文档shows specifically如何将 User-Agent header 添加到您的请求中:

var request = require('request');

var options = {
  url: 'https://api.github.com/repos/request/request',
  headers: {
    'User-Agent': 'request'
  }
};

function callback(error, response, body) {
  if (!error && response.statusCode == 200) {
    var info = JSON.parse(body);
    console.log(info.stargazers_count + " Stars");
    console.log(info.forks_count + " Forks");
  }
}

request(options, callback);
