问题描述
I'm trying to convert the accepted answer on (How to create a simple http proxy in node.js?) from http to https.
当我尝试从浏览器访问代理时,服务器退出并抛出此错误:
When I try to access the proxy from my browser, the server quits and throws this error :
events.js:171
throw TypeError('listener must be a function');
^
TypeError: listener must be a function
这是我的代码:
var https = require('https');
var fs = require('fs');
var ssl = {
ca: fs.readFileSync("cacert.pem"),
key: fs.readFileSync("key.pem"),
cert: fs.readFileSync("cert.pem")
};
https.createServer(ssl, onRequest).listen(3000, '127.0.0.1');
function onRequest(client_req, client_res) {
console.log('serve: ' + client_req.url);
var options = {
hostname: 'www.example.com',
port: 80,
path: client_req.url,
method: 'GET'
};
var ssl = {
ca: fs.readFileSync("cacert.pem"),
key: fs.readFileSync("key.pem"),
cert: fs.readFileSync("cert.pem")
};
var proxy = https.request(ssl, options, function(res) {
res.pipe(client_res, {
end: true
});
});
client_req.pipe(proxy, {
end: true
});
}
如您所见,我所做的更改很小,我不确定如何解决.
As you can see, I made very little changes and I'm not sure how to fix this.
有什么想法吗?
推荐答案
Looks like you've got the arguments to https.request
wrong (http://nodejs.org/api/https.html#https_https_request_options_callback). Should just be:
var proxy = https.request(options, function(res) {
res.pipe(client_res, {
end: true
});
});
您的证书信息应包含在链接页面的选项对象中:
Your certificate information should be included in the options object, from the linked page:
var options = {
hostname: 'encrypted.google.com',
port: 443,
path: '/',
method: 'GET',
key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};
options.agent = new https.Agent(options);
var req = https.request(options, function(res) {
...
}
