遇到这么个情况，请大神指教 这个接口 https://api.testnet.huobi.pro/v1/common/symbols 在浏览器上可以正常访问返回数据：
但是使用 axios 请求却会报错：
报错信息：
C:\Users\Maxzel\Desktop\huobi>node app.js
(node:7804) UnhandledPromiseRejectionWarning: Error: connect ETIMEDOUT 174.37.154.236:80

(node:7804) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)
(node:7804) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
之后尝试改 headers,将 axios 换成 request,superagent 来请求都无法得到返回数据，但为什么浏览器又可以直接返回呢？应该怎么解决？
