ASIHTTPRequest 可以重试吗？
有没有办法重试 ASIHTTPRequest？我在 REST 服务中使用自定义身份验证而不是基本 HTTP 身份验证，并且我想在会话过期时重试请求。对请求第二次调用 startAsynchronous 会导致异常。我想做这样的事情：
[request setCompletionBlock:^{
if ([request responseStatusCode] == 500)
{
// try to login again in case token expired
[server loginAndRetryRequest:request];
} else {
// parse response
}
}];
loginAndRetryRequest：将执行另一个ASIHTTPRequest来登录，当它完成时，它将从它的CompletionBlock再次启动原始请求（假设这在某种程度上是可能的）？
Is there a way to retry an ASIHTTPRequest? I'm using custom authentication in a REST service instead of basic HTTP authentication and I would like to retry a request if the session has expired. Calling startAsynchronous a second time on a request causes an exception. I would like to do something like this:
[request setCompletionBlock:^{
if ([request responseStatusCode] == 500)
{
// try to login again in case token expired
[server loginAndRetryRequest:request];
} else {
// parse response
}
}];
loginAndRetryRequest: will do another ASIHTTPRequest to login and when it is complete it will start the original request again from it's CompletionBlock (assuming this is possible somehow)?

应该可以制作请求的副本，然后在副本上再次执行
-startAsynchronous。版本 1.5 中添加了对 NSCopying 协议的支持，其中还包括超时情况下的自动重试（选择器
-setNumberOfTimesToRetryOnTimeout:）。另一个选项可以是检查其源代码，以了解在超时情况下自动重试是如何完成的超时，但复制并重新发出请求应该可以工作（这就是首先添加对 NSCopying 支持的原因）。
It should be possible to make a copy of the request and then execute
-startAsynchronousagain on the copy.Support for NSCopying protocol was added in release 1.5, which also includes automatic retry in case of timeout (selector
-setNumberOfTimesToRetryOnTimeout:.Another option could be checking their source code to see how the automatic retry is done in case of timeout, but copying and re-issuing the request should work (that was the reason to add support for NSCopying in the first place).
