如何确定要提交的HTTP POST事务的大小？ [英] How do I determine the size of a HTTP POST transaction to be submitted?

问题描述

我想确定要提交的HTTP POST事务的te大小（以字节为单位？）。我有一个包含大量表单数据的表单。当所有字段都填充了最大字符数（例如全部9个字符）并且表单通过POST方法提交时，没有问题，所有数据都会被保存。

I would like to determine te size (in bytes?) of a HTTP POST transaction to be submitted. I have a form with a lot of form data. When all fields are filled with the maximum number of characters (for example all 9's) and the form gets submitted through a POST method, there's no problem, and all data gets saved.

当我用空格替换所有字符（9）时，我在提交表格后得到404.

When I replace all characters (9's) by spaces, I get a 404 after submitting the form.

我假设我在这里发送了太多数据。我认为空格正在转换为％20，因此发布的字节数增加了三倍。

I'm assuming that I'm sending too much data here. I think the spaces are being converted to %20, so the amount of bytes posted are tripled.

我想在提交之前确定HTTP POST事务的大小表单，所以如果大小超过某个限制，我可以向用户显示一条消息。我更喜欢使用JavaScript。

I would like to determine the size of the HTTP POST transaction, before submitting the form, so I can display a message to the user if the size is over some limit. I'd prefer to use JavaScript.

有谁知道如何确定这个？

Does anyone know how to determine this?

推荐答案

404错误表示您尝试发布到的位置不存在，即当您使用空格发布时，网址可能会格式错误。

A 404 error indicates that the location you are trying to post to does not exist, i.e. the URL may be malformed when you post with spaces.

你能告诉我们代码吗？
