If the status is True it means you received data from the channel. If false, it means you are trying to read from a closed channel You can also use channels for communication between goroutines. Need to use 2 goroutines – one pushes data to the channel and other receives the data from...
http/server.Server对象有四个超时参数我们并没有设置,而且这一类参数通常会被忽视,作为一个服务器本身对所有进来的请求是有最长服务要求,我们一般关注比较多的是下游超时会忽视服务本身的超时设置。 typeServerstruct{// ReadTimeout is the maximum duration for reading the entire// request, including the body./...

The next tutorial will introduce the usage method through the command line parameters, or you can get the parameters by reading the configuration file.The specific format is to specify the configuration file by the @ symbol, for example: proxy @configfile.txt...
I've had mail conversations with two different projects using Go recently, both centered around the surprise that if many goroutines are blocked on a particular channel, and that channel becomes available, it is still possible for runnin...
How to resolve go-diameter connect error: use of closed network, Probably first step to troubleshoot is to capture using tcpdump or Wireshark and see what's happening. This smells like connection you're trying Closed network connection used in reading TCP [addr]->[addr] ...

我们知道一般在调用http client后都会close Response.Body,如下: {代码...} 下面我们来看下为什么resp.Body需要Close,一定需要Close吗?我们先通过"net/http/...
