第8步：花生壳

由于支付宝异步回调测试需要将网站发布到公网，所以需要将本地域名映射到公网

(1)登录

http://hsk.oray.com/

用户名:************

密  码:*********

(2)实名认证

https://console.oray.com/

(3)添加映射

https://b.oray.com/forward/

(4)访问将localhost换成zouke1220.oicp.net进行访问

http://zouke1220.oicp.net/College/Index

点击“报名”

点击“下一步”

function next_step() {

$("#formID").ajaxSubmit({

url: "/College/ValidateUserInfo",

type: "post",

success: function (data) {

if (data == "ok") {

$(".detail-message8").css({ "display": "none" });

$(".detail-message6").css({ "display": "none" });

$(".detail-message7").css({ "display": "block" });

} else {

alert(data);

return false;

}

}

});

}

点击“同意”

function iAgree(){

if ($("#checkedd").is(":checked")) {

$(".detail-message6").css({ "display": "none" });

$(".detail-message7").css({ "display": "none" });

$(".detail-message8").css({ "display": "block" });

} else {

return false;

}

}

点击“去支付”跳到订单确认页

function order_confirm() {

$("#SignUpForm").ajaxSubmit({

url: "/College/SignUp",

type: "post",

success: function (data) {

var obj=eval('(' + data + ')'); //json转json对象

$("#amount").val(obj.data.Amount);

} else {

return false;

}

}

});

}

点击“立即支付”

function go_pay() {

$("#OrderForm").ajaxSubmit({

success: function (data) {

$(".detail-message8").css({ "display": "none" });

$(".ee").css({ "display": "none" });

$(".pay_method").css({ "display": "none" });

$("#pay_button").html(data);

}

});

}

点击“登录账户付款”

点击“下一步”

点击“确认付款”

自动跳转到异步回调页面，将支付成功信息插入数据库

http://zouke1220.oicp.net/College/NotifyUrl

并跳转到同步通知页面显示支付成功页面

http://zouke1220.oicp.net/College/ReturnUrl

第9步：所有测试通过后将第4步配置信息换成正式环境的

注：部分页面还需要美化，完整版项目参见：http://www.gmkcn.com/
