這篇文章，我將通過一個簡單的例子來展現(xiàn)iPhone通過get和post方式請求asp.net webservice。
webservice
1、創(chuàng)建一個webservice
2、在webconfig中啟用http get 和http post。

iphone客戶端調(diào)用：
1、get的方式：
NSString<wbr></wbr>

2、post的方式：
NSString

NSURL
*url = [

NSMutableURLRequest
*req = [

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
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>
[req addValue:msgLength forHTTPHeaderField:@“Content-Length”];

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
[req setHTTPMethod:@“POST”];

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
[req setHTTPBody: [postString dataUsingEncoding:

|
<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
[activityIndicator startAnimating];
|
<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
conn = [[
NSURLConnection

self
];
|
<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
if
(conn) {

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
webData = [[
