一：前端浏览器禁用安全设置
chrome的话可以通过在命令行，输入chrome.exe –allow-file-access-from-files –user-data-dir=”C:/Chrome dev session” –disable-web-security
二：http服务器设置：
nginx的设置：
location /api {
add_header Access-Control-Allow-Origin $http_origin;
# add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Credentials true;
add_header Access-Control-Allow-Methods *;
add_header Access-Control-Allow-Headers $http_access_control_request_headers;
add_header Access-Control-Max-Age 3600;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://masConsole;
if ($request_method = OPTIONS){
return 200;
}
}
例子：编写html跨域的ajax页面：
<html>
<head>
<title>tab标签页</title>
<style>
* {
padding: 0;
margin: 0;
}
ul {
list-style-type: none;
}
body {
margin: 50px;
}
#ul {
height: 30px;
margin-bottom: 10px;
}
#ul li {
height: 30px;
line-height: 30px;
padding: 0 15px;
border: 1px solid #abcdef;
float: left;
margin-right: 3px;
cursor: pointer;
}
#ul li.current {
background: #abcdef;
}
#content div {
width: 300px;
height: 200px;
border: 1px solid #abcdef;
display: none;
}
#content div.show {
display: block;
}
</style>
<script src=”http://libs.baidu.com/jquery/2.0.0/jquery.js”></script>
<script>
$(function () {
$(“#ul li”).click(function () {
/*//1.点击li的时候切换样式
$(this).addClass(“current”).siblings().removeClass(“current”);
//2.根据li的索引值，来确定哪个div显示，其他div隐藏
$(“#content>div”).eq($(this).index()).show().siblings().hide();*/
//$(this).addClass(“current”).siblings().removeClass(“current”).parent().next().children().eq($(this).index()).show().siblings().hide();
$(this).addClass(“current”).siblings().removeClass(“current”).parent().next().find(“div”).eq($(this).index()).show().siblings().hide();
$.ajax({
url: ‘https://mp.sda.cn:9999/api/customer/uaa/nologin/login?Session_businessId=1’,
type: ‘post’,
data:{“nameLogin”:”000044″,”passwordLogin”:”000000″},
dataType: ‘json’,
success: function(data){
alert(JSON.stringify(data));
console.log(JSON.stringify(data));
},
error: function(err){
alert(JSON.stringify(err));
console.log(JSON.stringify(err));
}
});
});
});
</script>
</head>
<body>
<ul id=”ul”>
<li class=”current”>php</li>
<li>ruby</li>
<li>python</li>
</ul>
<div id=”content”>
<div class=”show”>php…介绍</div>
<div>ruby…介绍</div>
<div>python…介绍</div>
chrome的话可以通过在命令行，输入chrome.exe –allow-file-access-from-files –user-data-dir=”C:/Chrome dev session” –disable-web-security
</div>
</body>
</html>
