Empty details when viewing a request body.

[dbreese]

When attempting to view a request/response, the View Body for the Request Body is always blank, even though Content-Length is > 0.

Testing with 3.2.3 (and with latest from master)

This appears to be because NSUrlRequest.httpBody is nil, but httpBodyStream is what contains the data. Unfortunately, reading this stream consumes the body, so it looks like what needs to happen is for NetShears to copy the NSUrlRequest and recreate the request after reading the body.

Hi @dbreese
I'm facing the same issue as you mentioned before.
For a short debugging, currently I find a workaround for this issue by modifying the URLSessionConfiguration+Extension.swift by following code.

extension URLSessionConfiguration {
    
    @objc func fakeProcotolClasses() -> [AnyClass]? {
        guard let fakeProcotolClasses = self.fakeProcotolClasses() else {
            return []
        }
        var originalProtocolClasses = fakeProcotolClasses.filter {
            return $0 != NetworkInterceptorUrlProtocol.self && $0 != NetworkLoggerUrlProtocol.self && $0 != NetwrokListenerUrlProtocol.self
        }
        
        if NetShears.shared.listenerEnable {
            originalProtocolClasses.insert(NetwrokListenerUrlProtocol.self, at: 0)
        }
        if NetShears.shared.loggerEnable {
            originalProtocolClasses.insert(NetworkLoggerUrlProtocol.self, at: 0)
        }
        if NetShears.shared.interceptorEnable {
            originalProtocolClasses.insert(NetworkInterceptorUrlProtocol.self, at: 0)
        }
        return originalProtocolClasses
    }
    
}

The idea is to switch the position of NetwrokListenerUrlProtocol and NetworkLoggerUrlProtocol and it works for me!
