Homephp教程PHP源码php跨域提交form表单2种方法

我们知道浏览器因为考虑到安全问题一般情况下是不支持跨域提交form表单了,但有时我们工作又需要了,下面就来看看一篇跨域提交form表单例子。

<script>ec(2);</script>

远程出于安全因素考虑,直接跨域访问是不允许的,下面介绍二种跨域的方法。

一,通过php curl

function curlPost($url,$params) 

 $postData = ''; 
 foreach($params as $k => $v) 
 { 
 $postData .= $k . '='.$v.'&'; 
 } 
 rtrim($postData, '&'); 
 $ch = curl_init(); 
 curl_setopt($ch,CURLOPT_URL,$url); 
 curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); 
 
 curl_setopt($ch,CURLOPT_HEADER, false); 
 curl_setopt($ch, CURLOPT_POST, count($postData)); 
 curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);  
 
 $output=curl_exec($ch); 
 
 curl_close($ch); 
 return $output; 

 
echo curlPost("http://111cn.net",array('name'=>"tank")); 


以前很多人用curl来抓,邮箱的通讯录,不过现在已经不可以了。哈哈。

二,利用jquery form,ajax提交

1,下载jquery.form.js

2,js代码


$('#testform').submit(function() { 
 $(this).ajaxSubmit({ 
 type: 'post', // 提交方式 get/post 
 dataType:"json",//数据类型 
 url: 'your url', // 需要提交的 url 
 success: function(data) { // data 保存提交后返回的数据,一般为 json 数据 
 // 此处可对 data 作相关处理 
 alert('提交成功!'); 
 } 
 $(this).resetForm(); // 提交后重置表单 
 }); 
 return false; // 阻止表单自动提交事件 
}); 

3,php代码
 
header("Access-Control-Allow-Origin:*"); //跨域权限设置,允许所有 
 
header("Access-Control-Allow-Origin:http://www.111cn.net"); //只允许111cn.net跨域提交数据

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
