同步的HTTP请求

代码：

#import <Foundation/Foundation.h>



void request(NSString *urlString)

{

    NSLog(@"BEGIN");

    // make request object

    NSURL *url = [[NSURL alloc]initWithString:urlString];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url];

    [request setHTTPMethod:@"GET"];

    [request setTimeoutInterval:10];

    

    // send request

    NSError *error = nil;

    NSHTTPURLResponse *urlResponse = nil;

    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];

    

    if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) {

        NSString *responseText = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];

        NSLog(@"OK");

    }

    

    NSLog(@"END");

}



int main(int argc, const char * argv[])

{



    @autoreleasepool {

        request(@"http://www.code-style.com");

    }

    return 0;
