我想知道在HTTP和HTTPS上有相同API的情况下，最佳选择（架构）是什么。有没有办法在同一个AFHTTPRequestOperationManager中支持HTTP和HTTPS请求，还是应该有两个子类，一个用于HTTP请求，另一个用于HTTPS请求？
我觉得动态更改baseURL不是最佳解决方案
答案 0 :(得分：1)
您可以容纳两个AFHTTPClient *对象。一个用于http，另一个用于安全https。 这是基于我的Requester类的示例。

用法：
对于http：
[[Requester sharedInstance] requestToPath:@"user/authenticate"
method:HTTPMethodPOST
params:@{@"username":username,@"password":password}
complete:^(NSError *error, NSInteger statusCode, id json) {
if (!error) {
//do something with response
}
}];
对于https：
[[Requester sharedInstance] secureRequestToPath:@"user/authenticate"
method:HTTPMethodPOST
params:@{@"username":username,@"password":password}
complete:^(NSError *error, NSInteger statusCode, id json) {
if (!error) {
//do something with response
}
}];
