废话少说，具体步骤如下：
1、上传upload.lua到指定的目录，我的是_services/upload/conf
2、配置上传的SERVER（域名自己配制）
location = /upload {
client_max_body_size 512k;
content_by_lua '
ngx.header["Content-Type"] = "text/plain"
local upload = require("_service.upload.lib.upload")
local cjson = require "cjson"
local form = upload:new(512*1024*1024)
form:set_timeout(2000) -- 1 sec
while true do
local typ, res, err = form:read()
if not typ then
ngx.say("failed to read: ", err)
return
end
if (typ=="body") then
ngx.say(res)
end
if typ == "eof" then
break
end
end
local typ, res, err = form:read()
--ngx.say("read: ", cjson.encode({typ, res}))
';
}
3、HTML文件内容
<html><head> <title>上载文件表单</title></head> <body> <form enctype="multipart/form-data" action="http://***.com:7662/upload" method="post"> 请选择文件：<br> <input name="upload_file" type="file"><br> <input type="submit" value="上传文件"> </form> </body> </html>
