问题 I create requests POST-requests like this, where I specify timeout threshold: response = requests.post(url, data=post_fields, timeout=timeout) However, to determine a "good" threshold value, I would like to benchmark the server response time in advance. How do I compute the minimum and maximum response times for the server? 回答1: The Response object as returned by requests.post() has a property called elapsed , which give the time delta between the Request was sent and the Response was

问题 I found a couple of answers, but they seem to be specifically relating to Windows machines. So my question is what are the differences between pipes and sockets, and when/how should you choose one over the other? 回答1: what are the differences between pipes and sockets, and when/how should you choose one over the other? Both pipes and sockets handle byte streams, but they do it in different ways... pipes only exist within a specific host, and they refer to buffering between virtual files, or

问题 I'm trying to set up a blocking socket to timeout after 16 ms of trying to recvfrom() on a port. Platform is Windows. I've looked at tons of examples online and it seems really simple I just can't seem to get it to work. Any help would be appreciated! #include <winsock2.h> #include <string> #pragma comment(lib, "ws2_32.lib") #define PORT_NUM 8001 int main(void) { std::string localIP; sockaddr_in localAddr; sockaddr_in remoteAddr; hostent* localhost; char buffer[1024]; WSADATA wsData; int

问题 I'm working on a multiplayer game. The principle is simple, each of the two players sends each other periodically 512 bytes every 50 milliseconds. The problem is that about every 20-30 seconds players stop receiving data for sometimes one but sometimes even up to 20 seconds (though, sending had not been interrupted). At first I thought that this is caused by a slow network connection on either my side or on the side of my remote PC which I use for debugging. But then I noticed that all

问题 I am looking into stream reader timeout property. From the documentation, I did not understand, How this property works? What will happen when stream reader timeouts? Can somebody explain me these questions or point out to some better documentation than this. https://msdn.microsoft.com/en-us/library/system.io.stream.readtimeout(v=vs.110).aspx Sample code: TcpClient client = new TcpClient(serverIP, serverTcpPort); Stream s = client.GetStream(); StreamReader sr = new StreamReader(s); sr

问题 I need a method of converting a UNC path into a local path on the remote PC. So, for example, I could have a UNC path "\\PC2\SharedFolder\Foo\Bar.exe", which points to "C:\SomeFolder\Foo\Bar.exe" on PC2; the latter is what I want to return (I want to return the path of the share, not a mapped drive!). 回答1: Okay, I've posted the code to my solution below! Note that I haven't fully tested it yet, but it seems to work so far!!! /// <summary> /// Gets whether the specified path is a UNC path or
