Question

出现以下错误

Error: self signed certificate
at TLSSocket.<anonymous> (_tls_wrap.js:1105:38)
at emitNone (events.js:106:13)
at TLSSocket.emit (events.js:208:7)
at TLSSocket._finishInit (_tls_wrap.js:639:8)
at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:469:38)
code: 'DEPTH_ZERO_SELF_SIGNED_CERT',

我正在本地系统中运行应用程序，我的代码如下卡住了，请帮我忙一遍，在我尝试过几件事的node.js应用程序中设置cors

var express = require('express');
const axios = require('axios');
var cors = require('cors')
var app = express();
app.use(function(req, res, next) {
  res.header('Access-Control-Allow-Origin', req.get('Origin') || '*');
  res.header('Access-Control-Allow-Credentials', 'true');
  res.header('Access-Control-Allow-Methods', 'GET,HEAD,PUT,PATCH,POST,DELETE');
  res.header('Access-Control-Expose-Headers', 'Content-Length');
  res.header('Access-Control-Allow-Headers', 'Accept, Authorization, Content-Type, X-Requested-With, Range');
  if (req.method === 'OPTIONS') {
    return res.send(200);
  } else {
    return next();
  }
});

app.get('/', function (req, res) {
  res.send('Hello World!');
    axios.get('https://some-ip/api/v1/executions')
  .then(response => {
    console.log("-=-=-==- inside AXIOS");
    console.log(response.data);
    console.log("-=-=-=-=--=-=-=-=-SUCCESS");
    console.log(response.length);
  })
  .catch(error => {
    console.log("-=-=-==- inside ERRROR");
    console.log(error);
    console.log("-=-=-=-=--=-=-=-=-=---=-=-=-=--=-=-=-=-ERROR");

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

如果您已经导入了cors库，请使用它代替自己设置标题。

var cors = require('cors');

如果不需要凭据：

app.use(cors();

如果需要凭据：

app.use(cors({credentials: true, origin: true}));

现在要解决的问题或拒绝自行生成的证书，您可以使用以下方法防止这些错误：

process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0;

另外，看看https library from node

带有节点+快捷应用程序的“错误：自签名证书”
