一、同步GET请求方法
-(void)synchronizationGet
{
NSString *strURL = @"http://olasapi.sinaapp.com//index.php";
NSURL *url = [NSURL URLWithString:strURL];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSLog(@"请求完成");
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
NSLog(@"%@",dic);
}
二、异步get
-(void)asynchronousGet
{
NSString *strURL = @"http://olasapi.sinaapp.com//index.php";
NSURL *url = [NSURL URLWithString:strURL];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
_data = [NSMutableData new];
}
}
#pragma mark - NSURLConnection回调方法
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[_data appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"请求完成");
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:_data options:NSJSONReadingAllowFragments error:nil];
NSLog(@"%@",dic);
}
三、异步POST
-(void)asynchronousPost
{
NSString *strURL = @"http://olasapi.sinaapp.com//index.php";
NSURL *url = [NSURL URLWithString:strURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"POST"];
// [request setHTTPBody:@""]
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
_data = [NSMutableData new];
}
}
