Node.js POST导致[Error：socket挂断]代码：'ECONNRESET' [英] Node.js POST causes [Error: socket hang up] code: 'ECONNRESET'

问题描述

我创建了一个示例来将数据发布到休息服务，我发现当我有非ASCII或非拉丁字符（请参阅data.firstName）时，我使用TEST-REST.js的发布请求将抛出

I created a sample to post data to a rest services and I found out that when I have non-ascii or non-latin character (please see data.firstName), my post request using TEST-REST.js will throw

错误：{[错误：插座挂断]代码：'ECONNRESET'}。

error: { [Error: socket hang up] code: 'ECONNRESET' }.

// TEST-REST.js
var http = require('http');

var data = JSON.stringify({
  firstName: 'JoaquÌn',
});

var options = {
  host: '127.0.0.1',
  port: 3000,
  path: '/users',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Content-Length': data.length
  }
};

var req = http.request(options, function(res) {
  var result = '';

  res.on('data', function(chunk) {
    result += chunk;
  });

  res.on('end', function() {
    console.log(result);
  });
});

req.on('error', function(err) {
  console.log(err);
});

req.write(data);
req.end();

在我的休息服务中，它会像我这样发错：

and on my rest services, it throw me error like this:

SyntaxError: Unexpected end of input Sun Sep 08 2013 23:25:02 GMT-0700 (PDT) -     at Object.parse (native)
    at IncomingMessage.<anonymous> (/Volumes/Data/Program_Data/GitHub/app/node_modules/express/node_modules/connect/lib/middleware/json.js:66:27) info    at IncomingMessage.EventEmitter.emit (events.js:92:17)

    at process._tickDomainCallback (node.js:459:13)

如果我将firstName值从JoaquÌn替换为 abc'，一切都很好。我想我缺少一些支持或逃脱使其工作。

if I replace firstName value from 'JoaquÌn' to 'abc', everything works just fine. I think I'm missing something to support or escape to make it work.

有没有人有任何想法我如何解决这个问题？我也尝试过：require（'querystring'）。escape（model.givenName），它的作品，但我不满意。

does anyone have any idea how I solve this problem? I also tried following: require('querystring').escape(model.givenName), and it works but I'm not happy with it.

UPDATED
我发现如果我注释掉：app.use（express.bodyParser（））;则该错误消失。

UPDATED I found out that if I comment out: app.use(express.bodyParser());, the error disappears.

推荐答案

这是节点的问题，而不是表达的问题。 https://github.com/visionmedia/express/issues/1749

This is node's issue, not express's issue. https://github.com/visionmedia/express/issues/1749

解决，从

'Content-Length'：data.length

'Content-Length': data.length

to

'Content-Length'：Buffer.byteLength（data）

'Content-Length': Buffer.byteLength(data)

THUMB规则

始终使用如果您想查找字符串的内容长度，请将 Buffer.byteLength（）

更新

我们还应该在服务器端优雅地处理错误，以防止通过添加中间件来处理它的崩溃。

We also should handle error gracefully on server side to prevent crashing by adding middleware to handle it.

app.use(function (error, req, res, next) {
  if (!error) {
    next();
  } else {
    console.error(error.stack);
    res.send(500);
  }
});
