buffer 上传大文件时， client 报错

先贴出 client 和 server 的代码，node 的版本号为 v8.1.2

服务端代码：

// buffer_server.js const fs = require('fs'); const http = require('http'); const zlib = require('zlib'); const server = http.createServer((req, res) => { let index = 0; req.on('data', function(chunk) { console.log(++index, chunk.length); }); res.end('OK'); }) server.listen(3001, () => { console.log('started'); }); 

客户端代码：

// buffer_client.js const fs = require('fs'); const http = require('http'); const zlib = require('zlib'); const path = require('path'); const filename = process.argv[2]; const server = process.argv[3]; const optiOns= { port: 3001, hostname: server, method: 'PUT', protocol: 'http:', headers: { filename: path.basename(filename), 'Content-Encoding': 'gzib' } } const req = http.request(options, (res) => { console.log('client done'); }) fs.readFile(filename, (err, buffer) => { console.log('获取文件完毕\n'); console.log('开始压缩'); zlib.gzip(buffer, (err, buffer) => { console.log('压缩完毕'); console.log(buffer.length); // 1336191186 1.2G 左右的文件 req.write(new Buffer(1336191186)); req.end(); }) }) req.on('error', (err) => { console.log(err); /** * * 出现的错误： * * { Error: read ECONNRESET at exports._errnoException (util.js:1016:11) at TCP.onread (net.js:609:25) code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' } */ }) req.on('data', (data) => { console.log(data, 'data'); }) ``` 问题是，在上传 1.2GB 左右的压缩文件，一次性去通过 write 去发送给 server 之后，client 会报错，报错信息如下： ``` { Error: read ECONNRESET at exports._errnoException (util.js:1016:11) at TCP.onread (net.js:609:25) code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' } ``` 我自己判定是因为一次性 write 的 buffer 数量太大造成的，求解具体原因 谢谢
