/**
开始写请求参数
NSDictionary *dic=[值:参数名称];
把 dic 放到 parameters 里
例子:
[manager GET:@"" parameters:dic progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
同理,Post 也放在相同的地方
