Description
===========
This Lua library for capturing urls, decoding and logging:
Synopsis
========
```lua
lua_package_path "/path/to/lua-resty-readurl/lib/?.lua;;";
server {
location /test {
content_by_lua '
local readurl = require "resty.readurl"
local response, err = readurl.capture("/postgres/proxy/", {sql=sql}, true, {failure_log_level=ngx.CRIT, success_log_level=ngx.INFO, counter_dict=nginx_logging_dict})
ngx.say(response)
';
}
location /postgres/proxy/ {
return 200 "success";
}
}
```

Methods
=======
All of the commands return either something that evaluates to true on success, or `nil` and an error message on failure.
capture
-------
`syntax: response, err = readurl.capture(url, url_arguments, decode, log_table)`
`syntax: response, err = readurl.capture("/postgres/proxy/", {sql=sql}, true, {failure_log_level=ngx.CRIT, success_log_level=ngx.INFO, counter_dict=nginx_logging_dict})`
In case of success, returns the response of the location. In case of errors, returns `nil` with a string describing the error.

Installation
============
You can install it with luarocks `luarocks install lua-resty-readurl`
Otherwise you need to configure the lua_package_path directive to add the path of your lua-resty-readurl source tree to ngx_lua's LUA_PATH search path, as in
```nginx
# nginx.conf
http {
lua_package_path "/path/to/lua-resty-readurl/lib/?.lua;;";
...
}
```
This package also requires the lua-cjson package to be installed
Ensure that the system account running your Nginx ''worker'' proceses have
enough permission to read the `.lua` file.
