代码如下

复制代码

- (IBAction)upload:(id)sender {

    NSString *post = nil;

    post = [[NSString alloc] initWithFormat:@"message=%@",@"hello,world."];

    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;

    [request setURL:[NSURL URLWithString:@"http://localhost/kids/sendimg.php"]];

    [request setHTTPMethod:@"POST"];

    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];

    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

    [request setHTTPBody:postData];

    //[NSURLConnection connectionWithRequest:request delegate:self ];

    //同步请求的的代码

    //returnData就是返回得到的数据

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    NSString *result = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

    if(returnData)

     {

     NSLog(@"SOAP 返回 = %@",result);

     }

     else

    {

    NSLog(@"error!");

     }

}
