iOS iPhone通过get和post方式请求asp.net webservice

iPhone中Get和Post方式是本文要介绍的内容，这篇文章，我将通过一个简单的例子来展现iPhone通过get和post方式请求asp.net webservice。

webservice

1、创建一个webservice



2、在webconfig中启用http get 和http post。

<webServices>

<protocols>

<add
name="HttpSoap"/>

<add
name="HttpPost"/>

<add
name="HttpGet"/>

<add
name="Documentation"/>

</protocols>

</webServices>
复制代码

iphone客户端调用：

1、get的方式：

NSString *queryString
=

[NSString stringWithFormat:

@“http://10.5.23.117:5111/Service1.asmx/HelloWorld?param=123%@“,

ipAddress.text];

NSURL *url
= [NSURL URLWithString:queryString];

NSMutableURLRequest *req
= [NSMutableURLRequest requestWithURL:url];

[req addValue:@“text/xml; charset=utf-8”
forHTTPHeaderField:@“Content-Type”];

[req addValue:0 forHTTPHeaderField:@“Content-Length”];

[req setHTTPMethod:@“GET”];

[activityIndicator startAnimating];

conn = [[NSURLConnection alloc] initWithRequest:req
delegate:self];

if (conn) {

webData = [[NSMutableData data] retain];

}
复制代码

2、post的方式：

NSString *postString =@"123";
NSURL *url = [NSURL URLWithString:
@“http://10.5.23.117:5111/Service1.asmx/HelloWorld2”];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@“%d”, [postString length]];
[req addValue:@“application/x-www-form-urlencoded”
forHTTPHeaderField:@“Content-Type”];
[req addValue:msgLength forHTTPHeaderField:@“Content-Length”];
[req setHTTPMethod:@“POST”];
[req setHTTPBody: [postString dataUsingEncoding:NSUTF8StringEncoding]];
[activityIndicator startAnimating];
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn) {
webData = [[NSMutableData data] retain];
}
