（7）返回的结果格式为

xml result

 

 - (IBAction)buttonClicked:(id)sender {

 

NSString *soapMsg =[NSString stringWithFormat:@“”

“”
“%@”“”“”“”, 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];

Host: www.ecubicle.net
HTTP/1.1 200 OK

（5）返回结果发送为

xml result

 

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/1.1
Host: www.ecubicle.net
Content-Type: application/x-www-form-urlencoded
Content-Length: length
V4IPAddress=string

 （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 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

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];
}
}
