消息队列zeromq的go语言测试实例包

A Go interface to [ZeroMQ](http://www.zeromq.org/) version 4. ---------------------------------------------------------------- ## Warning Starting with Go 1.14, on Unix-like systems, you will get a lot of interrupted signal calls. See the top of a package documentation for a fix. ---------------------------------------------------------------- [](https://goreportcard.com/report/github.com/pebbe/zmq4) [](https://godoc.org/github.com/pebbe/zmq4) This requires ZeroMQ version 4.0.1 or above. To use CURVE security in versions prior to 4.2, ZeroMQ must be installed with [libsodium](https://github.com/jedisct1/libsodium) enabled. Partial support for ZeroMQ 4.2 DRAFT is available in the alternate version of zmq4 `draft`. The API pertaining to this is subject to change. To use this: import ( zmq "github.com/pebbe/zmq4/draft" ) For ZeroMQ version 3, see: http://github.com/pebbe/zmq3 For ZeroMQ version 2, see: http://github.com/pebbe/zmq2 Including all examples of [ØMQ - The Guide](http://zguide.zeromq.org/page:all). Keywords: zmq, zeromq, 0mq, networks, distributed computing, message passing, fanout, pubsub, pipeline, request-reply ### See also * [go-zeromq/zmq4](https://github.com/go-zeromq/zmq4) — A pure-Go implementation of ØMQ (ZeroMQ), version 4 * [go-nanomsg](https://github.com/op/go-nanomsg) — Language bindings for nanomsg in Go * [goczmq](https://github.com/zeromq/goczmq) — A Go interface to CZMQ * [Mangos](https://github.com/go-mangos/mangos) — An implementation in pure Go of the SP ("Scalable Protocols") protocols ## Requirements zmq4 is just a wrapper for the ZeroMQ library. It doesn't include the library itself. So you need to have ZeroMQ installed, including its development files. On Linux and Darwin you can check this with (`$` is the command prompt): ``` $ pkg-config --modversion libzmq 4.3.1 ``` The Go compiler must be able to compile C code. You can check this with: ``` $ go env CGO_ENABLED 1 ``` You can't do cross-compilation. That would disable C. ### Windows Build with `CGO_CFLAGS` and `CGO_LDFLAGS` environment variables, for example: ``` $env:CGO_CFLAGS='-ID:/dev/vcpkg/installed/x64-windows/include' $env:CGO_LDFLAGS='-LD:/dev/vcpkg/installed/x64-windows/lib -l:libzmq-mt-4_3_4.lib' ``` > Deploy result program with `libzmq-mt-4_3_4.dll` ## Install go get github.com/pebbe/zmq4 ## Docs * [package help](http://godoc.org/github.com/pebbe/zmq4) * [wiki](https://github.com/pebbe/zmq4/wiki) ## API change There has been an API change in commit 0bc5ab465849847b0556295d9a2023295c4d169e of 2014-06-27, 10:17:55 UTC in the functions `AuthAllow` and `AuthDeny`. Old: func AuthAllow(addresses ...string) func AuthDeny(addresses ...string) New: func AuthAllow(domain string, addresses ...string) func AuthDeny(domain string, addresses ...string) If `domain` can be parsed as an IP address, it will be interpreted as such, and it and all remaining addresses are added to all domains. So this should still work as before: zmq.AuthAllow("127.0.0.1", "123.123.123.123") But this won't compile: a := []string{"127.0.0.1", "123.123.123.123"} zmq.AuthAllow(a...) And needs to be rewritten as: a := []string{"127.0.0.1", "123.123.123.123"} zmq.AuthAllow("*", a...) Furthermore, an address can now be a single IP address, as well as an IP address and mask in CIDR notation, e.g. "123.123.123.0/24".
