阅读更多

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 >

iphone客户端调用：

1、get的方式：

NSString * queryString =
[NSStringstringWithFormat:
@“http: // 10.5.23.117:5111/Service1.asmx/HelloWorld?param=123%@“,
ipAddress.text];
NSURL * url = [NSURLURLWithString:queryString];
NSMutableURLRequest * req = [NSMutableURLRequestrequestWithURL:url];
[reqaddValue:@“text / xml;charset = utf - 8 ”forHTTPHeaderField:@“Content - Type”];
[reqaddValue: 0 forHTTPHeaderField:@“Content - Length”];
[reqsetHTTPMethod:@“GET”];
[activityIndicatorstartAnimating];
conn = [[NSURLConnectionalloc]initWithRequest:req delegate :self];
if (conn){
webData = [[NSMutableDatadata]retain];
}

2、post的方式：

view source print ?

NSString*postString =@"123";

NSURL*url = [NSURLURLWithString:

@“http://10.5.23.117:5111/Service1.asmx/HelloWorld2”];

NSMutableURLRequest*req = [NSMutableURLRequestrequestWithURL:url];

NSString*msgLength = [NSStringstringWithFormat:@“%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 = [[NSURLConnectionalloc] initWithRequest:req delegate:self];

if(conn) {

webData = [[NSMutableDatadata] retain];

}
