问题描述：在接受post字符串时，好像遇到=会被截断

我引用的是官方WIKI的代码

location = /test {

     client_max_body_size 50k;
     client_body_buffer_size 50k;

     content_by_lua '
         ngx.req.read_body()
         local args, err = ngx.req.get_post_args()
         if not args then
             ngx.say("failed to get post args: ", err)
             return
         end
         for key, val in pairs(args) do
             if type(val) == "table" then
                 ngx.say(key, ": ", table.concat(val, ", "))
             else
                 ngx.say(key, ": ", val)
             end

         end
     ';
 }

你这里的 POST 请求体是 JSON 格式，而不是 urlencoded 格式。所以你应该使用
ngx.req.get_body_data() 函数而不是 ngx.req.get_post_args().
更多细节请参见这两个函数的官方文档。
