原文WebService使用JSON格式传递笔记+JQuery测试
-
因为一些因素,必须改写WebService,很传统,但是很多公司还在用.. 因为XML 的关系,不想让他传递数据的时候过度肥大,所以我必须要尽量干净的JSON.. 于是开始我的改写旅程.. 首先,网络上好多好多好多文件,可能因为状况不同,测试过许多也让我搞混很多次.. 最后有找到答案..笔记一下.. 首先我开了三个不同的WebMethod 来测试三种不同的输出.. GetUserInfoString –取得字符串 GetOneUserInfo - 取得一个对象 GetUsers - 取得对象们

再来一个重点,在每一个Method 上方我都会加上www.it165.net
[WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
因为基于有时候我会需要使用GET 方式传递 所以我在Web Config 中加入 在system.web 中加入
<webServices> <protocols> <add name="HttpGet"/> <add name="HttpPost" /> <add name="Documentation" /> </protocols> </webServices> Web.Config 全文:
01.
<?
xml

这样试跑一下
奇怪为什么不是JSON ,别紧张…我们继续使用 JQuery 来呼叫看看.. JQuery Code :
01.
<input type=
"button"
id=
"ipt1"
value=
"test"
/>
02.
03.
<script type=
"text/javascript"
>
04.
05.
function
GetInfo() {
06.
var
$res;
07.
$.ajax({
08.
type:
"POST"
,
09.
url:
"Service1.asmx/GetOneUserInfo"
,
10.
contentType:
"application/json; charset=utf-8"
,
11.
async:
false
,
12.
cache:
false
,
13.
dataType:
'json'
,
14.
data:
"{name:'当麻',age:29}"
,
15.
success:
function
(data) {
16.
if
(data.hasOwnProperty(
"d"
)) {
17.
$res = data.d;
18.
}
19.
else
20.
$res = data;
21.
}
22.
});
23.
return
$res;
24.
}
25.
26.
27.
$(
'#ipt1'
).click(
function
() {
28.
var
res = GetInfo();
29.
alert(res.Name);
30.
});
31.
32.
33.
</script>
按钮按下去之后 我让他呼叫 GetOneUserInfo 这 method 并且使用POST 看下结果..
恩恩..的确是JSON, 但是多了一个 d 跟 __type 基本上 __type 不要去动他是不影响,但是 d 这东西必须得处理.. 进行改写..实测过上面三种不同的回传值..都 OK~~ 这样对于传统的 WebService Reference 呼叫 WebService 不会有影响.. 也可以透过JQuery 呼叫传递透过JSON…
