这次给大家带来jQuery+ajax调用WCF服务步骤详解,jQuery+ajax调用WCF服务的注意事项有哪些,下面就是实战案例,一起来看一下。
本文实例讲述了jQuery实现ajax调用WCF服务的方法。分享给大家供大家参考,具体如下:
关于AJAX调用WCF服务分为跨域和不跨域两种方式,今天咱们先介绍下不跨域下的调用方法。DEMO是在VS2008写的.
经过测试与研究,发现AJAX调用WCF服务必须满足以下条件
1.wcf的通讯方式必须使用webHttpBinding
2.必须设置32bcd8fda1beba957eb36b998b6a6c69节点的值
3.服务的实现必须添加标记
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
4.方法前面必须添加如下标记
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
5.ajax方法中传递的参数名称必须和wcf服务中提供的参数方法名称一致
以下是本人写的代码,标记颜色的是需要注意的地方
