lua-resty-http的粗略使用

在当前location中向"http://127.0.0.1:80/accp"发起一次请求，取得返回的数据做下一步操作

local http = require ("resty.http") ;
local httpc = http.new();
local res, err = httpc:request_uri( 
"http://127.0.0.1:80/accp",
--"http://192.168.5.198:8083/GT/login/gtdlyz.service",
{method = "POST", body = cjson.encode(usernamedata)}
)
if not res then 
	ngx.say("服务器内部错误，请重试！");
	return
end

if res.status==200 then

--取得返回的json
local body = res.body;
--解析json字符串
local real_data = cjson.decode(body);

if  real_data["password"] ~= password then
ngx.say("密码错误");
return ;					  
end
if  real_data["state"] == "1" then 
ngx.say("用户已销户");
return ;					  
end
if  real_data["state"] == "2" then
ngx.say("用户已被冻结");
return ;					  
end
