413 Full HEAD error
提问by leo
i have made a dynamic blog engine, where multiple authors can publish articles.
我制作了一个动态博客引擎，多个作者可以在其中发布文章。
the author goes to a page where he inputs the 'article' 'description' and 'the whole article' in three <textarea>Then i store all the values in 3 variables and store it in the database via an ajax based request.
作者转到一个页面，他在其中输入了“文章”、“描述”和“整篇文章”三部分<textarea>然后我将所有值存储在 3 个变量中，并通过基于 ajax 的请求将其存储在数据库中。
The Problem: The HttpServerRequest is too large and it gives a 413 FULL Head error, and the request doesnt get through.

Is there an alternate way to send a big server request?? I also read on google that we can change the size, to match huge requests?
有没有其他方法可以发送大型服务器请求？我还在谷歌上读到我们可以改变大小，以匹配巨大的请求？

答案首选 java、HTML、javascript（或）jQuery
EDITI read herethat we can set the size limit of post request in header? How can i do it in GAE?
编辑我在这里读到我们可以在标题中设置发布请求的大小限制？我怎样才能在 GAE 中做到这一点？

Don't use HEAD or GET for large parameters. Those should only be used for idempotent requests(repeating it doesn't break anything), and requests that only retrieve data(i.e. searching or filtering a product database) anyway.
不要对大参数使用 HEAD 或 GET。那些应该只用于幂等请求（重复它不会破坏任何东西），以及无论如何只检索数据（即搜索或过滤产品数据库）的请求。
Use a POST request instead:
改用 POST 请求：
<script>
$(function(){
$('.publish').click(function(){
title = $('#title').val();
description = $('#description').val();
article = $('#article').val();
$.ajax({
type: "post",
url: "/articles",
data: {action:'add', title:title, description:description, article:article},
// .... skipped unchanged lines
</script>
This is a one-line change.
这是单行更改。
On the server, make sure you use doPost()instead of doGet()in the servlet. You can get parameters in a similar fashion.
在服务器上，请确保您在 servlet 中使用doPost()而不是doGet()。您可以以类似的方式获取参数。

In my case HEADER was full because cookie value was too large for SESSIONID. I deleted all cookie for that site and it worked.
在我的情况下，HEADER 已满，因为 cookie 值对于 SESSIONID 来说太大了。我删除了该站点的所有 cookie 并且它起作用了。
