AFHTTPSessionManager *session = [AFHTTPSessionManager manager];
session.requestSerializer = [AFJSONRequestSerializer serializer];
NSMutableDictionary *params = [NSMutableDictionary dictionary];
params[@"start"] = @"1";
params[@"end"] = @"5";
    
[session POST:urlStr parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"请求成功");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"请求成功");
}];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
