本文實例為大家分享了基于Express框架使用POST傳遞Form數據的具體代碼，供大家參考，具體內容如下
客戶端使用Form發送數據
在客戶端Html文件中Form代碼如下：
<!-- POST test --><form action="/test" method="post" id="foo" > <input type="text" name="username"> <input type="password" name="password"> <input type="submit"></form>
在服務器端處理'/test' POST請求的代碼如下：
var bodyParser = require('body-parser'); // ... // create application/json parservar jsonParser = bodyParser.json() // create application/x-www-form-urlencoded parservar urlencodedParser = bodyParser.urlencoded({ extended: false }) // ... // // request from form of the html file// app.post('/test', urlencodedParser, function(req, res) { if (!req.body) return res.sendStatus(400); console.log('Username: ' + req.body.username); console.log('Password: ' + req.body.password); res.send('Welcome, ' + req.body.username); });客戶端使用Node.js發送數據
在客戶端使用Node.js發送Form數據的代碼
const http = require('http'); var data = { username: 'foo', password: "test" }; var postData = require('querystring').stringify(data); console.log( postData ); function form(){ var options = { method: "POST", host: "localhost", port: 80, path: "/test", headers: { "Content-Type": 'application/x-www-form-urlencoded', "Content-Length": postData.length } }; var body = ''; var request = http.request( options, function(res) { // show results console.log('STATUS: ' + res.statusCode); res.setEncoding('utf8'); res.on('data', function(chunk) { body += chunk; console.log('BODY: ' + chunk); }); res.on('end', function(err) { console.log( ' complete.'); }); }); request.on("error", function(e) { console.log('upload Error: ' + e.message); }) request.write( postData ); request.end(); } form();客戶端使用jQuery發送數據
客戶端使用jQuery的 $.ajax post數據，
<!DOCTYPE html><html><head> <meta charset="utf-8"> <title>Post Data</title> <script src="jquery.min.js" type="text/javascript"></script> <script src="client.js" type="text/javascript"></script></head><body> <!-- POST test --><form action='/update' method='post' id='foo' > Parameters<table border="0"> <tr> <td> File Name</td> <td> <input type="text" name="filename" value = "foo.txt" /></td> </tr></table> </form><button name="button1" id='startButton' > Update</button> </body></html>
client.js
$(document).ready(function(){ //try joining the server when the user clicks the connect button $("#startButton").click(function () { var filename = $("#input[name=filename]").val(); $.ajax({ type: 'POST', url: "/update", // dataType: "jsonp", data: { "filename": filename} , jsonpCallback: 'callback', success: function (data) { // ... }, error: function (xhr, status, error) { console.log('Error: ' + error.message); }, }); });});server端使用node.js解析數據
//// Modules var express = require('express'); var bodyParser = require('body-parser'); //// Global variables var app = express(); // body parserapp.use(bodyParser.json());app.use(bodyParser.urlencoded({ extended: false })); /* POST /update listing. */app.post('/update', function(req, res, next) { // Checking require if (!req.body) return res.sendStatus(400); console.log('filename: ' + req.body.filename); res.redirect('./');});以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VeVb武林網。
