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 >
< protocols >
< add name ="HttpSoap" />
< add name ="HttpPost" />
< add name ="HttpGet" />
< add name ="Documentation" />
</ protocols >
</ webServices >
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];
}
[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];
}
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];
}
