如何确保使用jquery$.post在UTF8中提交的变量-HowtoensurevariablessubmittedinUTF8usingjquery$.post

First of all, to see what charset ìs used for requests, install something like Firebug and check the 'Content-Type' header of your request/response. It will look something like 'application/json; charset=...'. This should be charset=utf-8 in your case.

首先，要查看请求使用的字符集，请安装Firebug之类的东西，并检查请求/响应的“Content-Type”头。它看起来像'application/json;charset =…”。在您的例子中，应该是charset=utf-8。

My guess why it worked when posting a form is probably because of x-www-form-urlencoded - non-alphanumeric characters are additionally encoded on the client side and again decoded on the server, that's the difference to posting the data directly.

我猜测，在发布表单时，它为什么会起作用，可能是因为x-www-form- urlencodes—非字母数字字符在客户端被额外编码，然后在服务器上再次解码，这与直接发布数据是不同的。

This means that somewhere there is a wrong encoding at work. PHP treats your strings agnostic to its encoding by default, so I would tend to rule it out as the source of the error. jQuery.post also uses UTF-8 by default... so my suspect is the filename variable. Are you sure it is in UTF-8? Where and how do you retrieve it?

这意味着在某些地方存在错误的编码。PHP默认情况下不考虑字符串的编码，因此我倾向于将其排除为错误的来源。jQuery。post默认也使用UTF-8…我的怀疑对象是文件名变量。你确定是UTF-8吗?你在哪里以及如何取回它?

You should probably also ensure that the actual HTML page is also sent as UTF-8 and not, let's say iso-8859-1. Have a look at this article for a thorough explanation on how to get it right.

您还应该确保实际的HTML页面也被发送为UTF-8，而不是，比方说iso-8859-1。看一看这篇文章，就如何正确地做一个详细的解释。

guys this was a Mac problem!! i just tested it on windows as my server and now everything works fine. So beware when u r using Mac as a server with MySql having UTF8 as charset and collation. I guess the Mac stores the folder and file name in some different encoding and not UTF-8.

伙计们，这是Mac的问题!!我刚刚在windows上测试了它作为我的服务器，现在一切正常。所以，当你使用Mac作为一个服务器时，要小心，因为MySql的UTF8是charset和collation。我猜Mac将文件夹和文件名存储在不同的编码中，而不是UTF-8。

You answer might be here: How to set encoding in .getJSON JQuery

您的答案可能是:如何在.getJSON JQuery中设置编码

As it says there, use $.ajax instead of $.post and you can set encoding.

正如上面所说，使用$。ajax而不是美元。post和您可以设置编码。

OR, as it says in the 2nd answer use $.ajaxSetup to set the encoding accordingly.

或者，就像第二种回答说的，用$。ajaxSetup相应地设置编码。
