evmongoose

DEPRECATED. Replaced by libuhttpd, libuwsc, libumqttc

Evmongoose(中文)(github)

Evmongoose is an asynchronous, event(libev) based multi-protocol embedded networking library
with functions including TCP, HTTP, WebSocket, MQTT and much more. It is based on mongoose
and libev implementation and it\’s support Lua API.

Evmongoose supports highly customized to extend your application. Before I started this project, I had never found a HTTP server
library that was satisfied with the event based framework, and those HTTP server libraries could only loop it\’sown objects and
could not add my own objects. For example, I want to monitor a signal or a file through the event.

Features

• New from evmongoose

  • Using libev programming
  • Highly customized to extend your application based on libev
  • Lua API(except wrapper for evmongoose and additional include frequently-used posix C API)

• Inherited from mongoose

  • plain TCP, plain UDP, SSL/TLS (over TCP, one-way or two-way)
  • Alternative openssl and mbedtls
  • HTTP client, HTTP server
  • HTTP File Upload
  • Proxy
  • WebSocket client, WebSocket server
  • MQTT client, MQTT broker
  • CoAP client, CoAP server
  • DNS client, DNS server, async DNS resolver
  • Url Rewrite

Example

• simplest web
• simplest web on ssl
• http client
• async DNS resolver
• Lua

How To Compile

For Ubuntu

Install dependency Libraries

• libev-dev libssl-dev lua5.1 liblua5.1-0-dev lua-zlib

    sudo apt install libev-dev libssl-dev lua5.1 liblua5.1-0-dev lua-zlib
  

• lua-ev

    git clone https://gi*thu*b.co*m/brimworks/lua-ev.git
    cd lua-ev
    cmake . -DINSTALL_CMOD=$(lua -e \"for k in string.gmatch(package.cpath .. \\\";\\\", \\\"([^;]+)/..so;\\\") do if k:sub(1,1) == \\\"/\\\" then print(k) break end end\")
    make && sudo make install
  

Install Evmongoose(HTTPS Support Default)

git clone https://gith**ub*.com/zhaojh329/evmongoose.git
cd evmongoose
mkdir build
cd build
cmake ../
make && sudo make install

Install Evmongoose(Disable HTTPS Support)

git clone https://gith**ub*.com/zhaojh329/evmongoose.git
cd evmongoose
mkdir build
cd build
cmake ../ -DHTTPS_SUPPORT=OFF
make && sudo make install

For General embedded environment

First, cross compile Lua

Cross compile lib-ev

git clone https://*git*hub.co*m/kindy/libev.git
cd libev/src
sh ./autogen.sh
export PATH=/home/zjh/lede/staging_dir/toolchain-mipsel_24kc_gcc-5.4.0_musl/bin:$PATH
./configure --host=mipsel-openwrt-linux --prefix=`pwd`/obj
make && make install

Cross compile Lua-ev

git clone https://gi*thu*b.co*m/brimworks/lua-ev.git
cd lua-ev
export PATH=/home/zjh/lede/staging_dir/toolchain-mipsel_24kc_gcc-5.4.0_musl/bin:$PATH

# xxxxx is your cross compiler with directories
cmake . -DCMAKE_C_COMPILER=mipsel-openwrt-linux-gcc -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=BOTH -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY -DCMAKE_FIND_ROOT_PATH=xxxxx
make

Cross compile evmongoose

git clone https://gith**ub*.com/zhaojh329/evmongoose.git
cd evmongoose
export PATH=/home/zjh/lede/staging_dir/toolchain-mipsel_24kc_gcc-5.4.0_musl/bin:$PATH

make

C API reference manual

Evmongoose dose not change the usage of API in mongoose and libev,
so please refer to the API Manual of mongoose and libev.
Only one thing to notice is that mg_mgr_poll is no longer invoked when using evmongoose.

In addition, evmongoose added a new API: mg_mgr_set_loop, which is used to set libev\’s loop for Mgr.
If the function is not called, the Mgr will use the default loop:EV_DEFAULT.
