项目用node+express+ejs写的h5页面，所有的数据都是通过调取java第三方接口的数据，然后用ejs渲染，放到测试环境测试的时候不间断的服务挂掉、报错"502 Bad Gateway nginx "错误，请问如何解决呢？是获取接口的数据的问题还是node里面需要配置什么？

router.get(’/:id’,function(req,res,next){

const params = {

id:req.params.id

}

request({

url: ${API}course/detail,

method: req.method,

json: true,

headers: {

“content-type”: “application/json”,

},

qs: params

}, function(error, response, body) {

if (!error && response.statusCode == 200) {

res.render(‘learn’,body)

}

});

})

加了pm2要好点，至少崩了会自动重启，这个是pm2发的错误邮件，新手表示看不懂，哪位能看下用了request和request-promise这两个插件请求数据
