Question

我正在使用node.js的请求模块，并且我正在逐渐收到未被捕获的错误（仅在生产时，可能在node.js更新后）

节点版本：0.12.4，请求版本：2.55.0

1000-2000个请求可以成功执行，但后来我遇到了这样的错误：

Error: Protocol "http:" not supported. Expected "https:".
    at new ClientRequest (_http_client.js:75:11)
    at Object.exports.request (http.js:49:10)
    at Request.start (/path/node_modules/request/request.js:963:30)
    at Request.end (/path/node_modules/request/request.js:1531:10)
    at end (/path/node_modules/request/request.js:734:14)
    at Immediate._onImmediate (/path/node_modules/request/request.js:748:7)
    at processImmediate [as _immediateCallback] (timers.js:358:17)"

我该如何解决？为什么会出现？感谢）

Answer 1

这是因为使用SSL运行应用程序但通过普通HTTP调用它。您需要进行检查以确定客户端是使用HTTP还是HTTPS，然后修改您的代码以适应。

这样的事情应该有效：

var express = require('express')
    , http = require('http')
    , https = require('https')
    , app = express();

http.createServer(app);
https.createServer({ ... }, app);

然后当您处理您的请求时，请执行类似

的操作

app.get('/your-route', function(req, res) {
    if (req.secure) {
        var req = https.get(url, function(res) { ... });
    } else {
        var req = http.get(url, function(res) { ... });
    }
});

req.secure标识连接是否安全。请注意我们如何根据连接类型使用https和http。

仅供参考，我遇到了类似的错误

TypeError [ERR_INVALID_PROTOCOL]: Protocol "http:" not supported. Expected "https:"
    at new ClientRequest (_http_client.js:120:11)
    at request (http.js:42:10)

    at TLSSocket.Readable.push (_stream_readable.js:224:10)
    at TLSWrap.onStreamRead (internal/stream_base_commons.js:94:17)

这是由于提取指令中网址中的拼写错误

        fetch(`https://xxx@yyy.com`, {
            method: 'post',
            body: JSON.stringify(eventLogEntry),
            headers: { 'Content-Type': 'application/json' },
            agent: agent
        })

当我将网址固定为xxx.yyy.com时，我的问题就消失了

Nodejs错误：不支持协议“http：”。预计“https：”
