### post数据非常大,所以会将其切割,分段发送 ~~~ <form action="http://localhost:8081/" method="post"> <p>用户名<input type="text" name="user"></p> <p>密码<input type="password" name="pwd"></p> <p><textarea name="txt" id="" cols="30" rows="10"></textarea></p> <p><input type="submit"></p> </form> ~~~ ~~~ const http = require("http"); http.createServer((req,res)=>{ /* data->有一段数据到达(发生多次) */ var str = "" var i = 1; req.on("data",function(data){ console.log(`第${i++}发送数据`) str+=data; }) /* end->全部数据发送完毕(发生一次) */ req.on("end",function(){ console.log(str) }) }).listen(8080) ~~~
