A站(www.a.com)，有個form表單，ajax提交到 B站(www.b.com)，還附帶個驗證碼。
A站上的表單代碼如下：
|
<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.6.4/jquery.min.js"></script> <script> function send(){ $.ajax({ cache:true, type:"POST", url:"http://www.b.com/plus/diy.php", data:$('#diyform').serialize(), xhrFields:{withCredentials: true}, //ajax跨域提交需要 crossDomain:true, //ajax跨域提交需要 success: function(data){ if(data=="success"){ alert('發(fā)送成功!'); }else{ alert('發(fā)送失敗!'); } } }); } </script> <form action="" enctype="multipart/form-data" method="post" id="diyform"> <input type="hidden" name="action" value="post" /> <input type="hidden" name="diyid" value="2" /> <input type="hidden" name="do" value="2" /> <input type="hidden" name="dede_fields" value="name,text" /> <input type="hidden" name="dede_fieldshash" value="c2be5bb5ec45d9d01ca9f60dc469b3fb" /> <p> 姓名： <input type='text' name='name' id='name' /> </p> <p> 驗證碼： <input type="text" name="validate"><img src="http://www.b.com/include/vdimgck.php" align="absmiddle" onclick="this.src='http://www.b.com/include/vdimgck.php?tag='+Math.random();" style="cursor:pointer;"> </p> <div onclick="send()">提交</div> </form> |
1、提交到 http://www.b.com/plus/diy.php
2、驗證碼 http://www.b.com/include/vdimgck.php
3、ajax 跨域必需js代碼
xhrFields:{withCredentials: true},
crossDomain:true,
B站上的 /plus/diy.php 文件上面加入
header("Access-Control-Allow-Credentials:true");
header("Access-Control-Allow-Origin:http://www.a.com");
