nginx中SSI问题的研究

最近感觉挺爽的，这个项目团队没有一个专门做PHP的，我是第一个进来做PHP（当然还有前端）的，哈哈，我会设计修改出适合我们业务的PHP框架，哈哈，感觉会学到很多东西的样子，前几天在组内20几个前辈面前讲php框架，以及跟大牛们探讨适合我们的php框架，感觉表达能力太差了，知道的东西表达不清楚，还要我的导师去帮我表达，这里感谢下我的导师于洪磊（简称磊哥），磊哥简直就是我的偶像，我没见过那么有深度的程序员，技术牛B这是肯定的了，对技术外的了解超出了我的想象，磊哥看的书很多，涉猎很广泛，尤其在历史和文学方面，聊起天来有理有条、幽默风趣、时不时的引用几句谁谁谁的文章，啊！真感觉不出来是一个技术大牛，更像是罗永浩那样的人，哈哈，在最近2年磊哥就是我的目标，多看书、多讲话，提高自己的表达能力，要不然自己知道的东西不能通过最直接的表达分享出去，这就很郁闷了。

瞎扯了这么多，进入正题吧，今天要说的是一个关于SSI的问题，这里先介绍下SSI

SSI是Server Side Inclde的缩写，就是服务端包含的意思，我今天要说的只是用到了nginx中SSI模块的include命令，这个命令会包含一个页面，然后在nginx服务器中展开。

我遇到的是什么问题呢？现在有个富文本编辑编辑器，要求保存页面篇，输入一些html（包括SSI include命令），然后保存在数据库，保存之后还要求可以编辑，要求富文本编辑器中的内容就像这样内容就像下面这样：

问题就处在了这里，这里面包含了ssi命令。

这个如果直接访问的只显示Hello World！！！，我们对nginx做如下配置：

这个时候如果有mime type为text/shtml类型的数据通过nginx的时候，nginx就回去解析这些命令，这导致了个问题，我在数据库中查出数据然后返回给客户端富文本编辑器就会出错，我的echo内容如下所示：

页面会显示这种形式：

这我就有点郁闷了，因为服务器上其他功能必须用到ssi，而我这里又不需要，这个该怎么办呢？

这个时候我想到了ssi\_types，这里面设置的是text/html，而常用的还有一种text/plain，这种类型的mime是什么呢，在浏览器中他会把所有的内容原封不动的显示出来，不去进行解析html、css。用了这种类型，nginx就不会进行展开了，试试在输出之前修改mime：

果然，在修改了mime之后，输出和数据库中的一致，原封不动：

看样子问题解决了，但是没想到由于历史原因，后台的编辑框内内容和其他内容是一起返回的，这下囧了，如果设置为text/plain所有的内容都已文本形式显示在浏览器，问题等于还是没有解决~~

这个时候想到nginx配置，由于需要nginx进行解析展开的文件一般为shtml、html等后缀，而查数据库一般为php所以我可以将ssi的所用于缩小为后缀名为shtml、html的文件，看看配置，这里我讲ssi配置信息移动到一个匹配中，再看看效果，

新建html、php文件，内容类似，

html：

会发现php访问只输出了Test!!，其他内容要查看源码才可以看见，html中则会进行解析，输出对应包含文件的内容或者没找到报错！！至此问题基本解决了，具体情况下周上班之后试下这个方法，应该没问题，测试的时候都是ok的。

今天在实际代码中没有用这些，使用了一个简单的函数，哈哈，将大小于号转化为html编码，nginx解析ssi的时候不认识，但是浏览器还是认识的，ok，问题解决，没有修改nginx哦配置
