xserver

a simple http server written in c language.

It is a freshman task of @UniqueStudio in 2021 spring. I write it as a demo because I'm the task publisher.

How to use

1. install cjson (see [tool chain](###tool chain))
2. edit conf.json to modify config
3. mkdir build && cd build && cmake .. && make. The executable file is at build/src/x-server
4. the x-server binary file will get conf file path from environment variable env_file_path in release mode(default mode). please set env_file_path first before executing the binary file.

you can remove command for _DEBUG_CONFIG_PATH in src/conf/conf.h and set the proper value of it to set project to debug mod. it will load file from the value you defined before.

tool chain

• cJSON

install cjson locally.(by following make install step in cjson readme)

run install will install cjson lib at /usr/local/lib. append it in file /etc/ld.so.conf. else program will fail with error error while loading shared libraries: libcjson.so.1: cannot open shared object file: No such file or directory.

then run command /sbin/ldconfig on root permission to refresh it.

TODO list

• uniform log handle
• global control def management
• http big file body handle
