1.从一个URL GET数据
方法1：
NSURL * url = [NSURL URLWithString:@"http://www.weather.com.cn/data/sk/101010100.html"];
NSURLRequest * req = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation * oper = [[AFHTTPRequestOperation alloc]initWithRequest:req];
[oper setCompletionBlockWithSuccess:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
NSLog(@"succ:%@",operation.responseString);
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
NSLog(@"fail:%@",error);
}];
NSOperationQueue * q = [NSOperationQueue new];
[q addOperation:oper];
方法2：
AFHTTPRequestOperationManager * m = [AFHTTPRequestOperationManager manager];
m.responseSerializer = [AFHTTPResponseSerializer serializer];
[m GET:@"http://www.weather.com.cn/data/sk/101010100.html" parameters:nil success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
NSLog(@"succ:%@",operation.responseString);
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
NSLog(@"fail:%@",error);
}];
2.POST
AFHTTPRequestOperationManager * m = [AFHTTPRequestOperationManager manager];
m.responseSerializer = [AFHTTPResponseSerializer serializer];
NSMutableDictionary * d = [NSMutableDictionary new];
[d setValue:@"白羊座" forKey:@"consName"];
[d setValue:@"today" forKey:@"type"];
[d setValue:@"8e8cb4ebeb7bbc14449fc62e6fe1ed7f" forKey:@"key"];
[m POST:@"http://web.juhe.cn:8080/constellation/getAll" parameters:d success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
NSLog(@"succ:%@",operation.responseString);
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
NSLog(@"fail:%@",error);
}];
}
