1、創建一個webservice
2、在webconfig中啟用http get 和http post。

iphone客戶端調用：
1、get的方式：

2、post的方式：

NSURL
*url = [

NSString
*msgLength = [
NSString

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
[req addValue:@“application/x-www-form-urlencoded”

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
[activityIndicator startAnimating];

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
conn = [[

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
if

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
