如何检查github API无法连接到github

Question

是否有任何方法可以从github api中检查其无法连接到github或internet是否连接到github或internet，因此当我通过以下方式初始化该api时：

GitHubApi = require("github"); github = new GitHubApi({ version: "3.0.0" });

它应该通过处理异常来告诉您，无法连接到github或没有连接的internet，从而允许我停止使用此API的其他操作。因为目前我得到了这个例外。

我检查了一个异常来检查

 if (error.code == 500) {
            message = "Sync : Internet Not Connected or Unable to Connect to Github. Exception Logged in Console";
            msgBox = false;
        }
