?
NSString *soapMsg =[NSString stringWithFormat:@“<?xml version=\“1.0\“ encoding=\“utf-8\“?>”
“<soap:Envelope xmlns:xsi=”“\“http://www.w3.org/2001/XMLSchema-instance\“ “

“<V4IPAddress>%@</V4IPAddress>”“</FindCountryAsXml>”“</soap:Body>”“</soap:Envelope>”, ipAddress.text];
//---print it to the Debugger Console for verification---
NSLog(soapMsg);
NSURL *url = [NSURL URLWithString:@“http://www.ecubicle.net/iptocountry.asmx”];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
//---set the various headers---
NSString *msgLength = [NSString stringWithFormat:@“%d”, [soapMsg length]];
[req addValue:@“text/xml; charset=utf-8” forHTTPHeaderField:@“Content-Type”];
[req addValue:@“http://www.ecubicle.net/webservices/FindCountryAsXml”forHTTPHeaderField:@“SOAPAction”];

//---set the HTTP method and body---
[req setHTTPMethod:@“POST”];
[req setHTTPBody:[soapMsg dataUsingEncoding:NSUTF8StringEncoding]];
[activityIndicator startAnimating];
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn) {
webData = [[NSMutableData data] retain];
}
}

三：Using HTTP GET
?
请求格式
GET /iptocountry.asmx/FindCountryAsXml?V4IPAddress=string HTTP/1.1Host: www.ecubicle.net
HTTP/1.1 200 OK

?
?（1）请求的地址为http://www.ecubicle.net/iptocountry.asmx/FindCountryAsXml?V4IPAddress=“aa”.

?
请求发送
?- (IBAction)buttonClicked:(id)sender {NSString *queryString =[NSString stringWithFormat:@“http://www.ecubicle.net/iptocountry.asmx/FindCountryAsXml?V4IPAddress=%@“,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];
}
}??
四：?Using HTTP POS T
?
请求格式POST /iptocountry.asmx/FindCountryAsXml HTTP/1.1Host: www.ecubicle.net
Content-Type: application/x-www-form-urlencoded

?（2）Content-Type为“application/x-www-form-urlencoded”
?（3）Content-Length 为V4IPAddress=string的长度。
???? The data to be sent is formatted as key/value pairs — key1=value1&key2=value2&key3=value3. Unlike
???? HTTP GET, the data are not sent through the query string; it is sent after the HTTP headers.
（4）The HTTP Method is POST.
（5）返回结果格式为
HTTP/1.1 200 OKContent-Type: text/xml; charset=utf-8
Content-Length: length
<?xml version=”1.0”?>
xml result
?
请求发送
?
- (IBAction)buttonClicked:(id)sender {
NSString *postString =[NSString stringWithFormat:@“V4IPAddress=%@“, ipAddress.text];
NSLog(postString);
NSURL *url = [NSURL URLWithString:@“http://www.ecubicle.net/iptocountry.asmx/FindCountryAsXml”];
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];
}
