test_read_body.lua:
ngx.req.read_body()
local req_body = ngx.req.get_body_data()
if req_body then
ngx.say("get " .. #req_body .. " bytes request body from memory")
else
local path = ngx.req.get_body_file()
if path ~= nil then
local f = assert(io.open(path, "rb"))
req_body = f:read("*all")
ngx.say("get " .. #req_body .. " bytes request body from file " .. path)
else
ngx.say("get no request body")
end
end
nginx.conf:
location /test_read_body {
client_max_body_size 100m;
content_by_lua_file "conf/test_read_body.lua";
}
当body不超过client_body_buffer_size的时候，是正常的。
当body超过client_body_buffer_size，未超过client_max_body_size时，会将body放到临时文件，ngx.req.get_body_file()返回路径，但从这个路径里读时，返回错误，找不到文件

content_by_lua*和access_by_lua*都不行。
是什么原因呢？
