 最近有些朋友和我说，wordpress的后台在本地打开都超慢。不知道为什么，负载什么的都没有。

yii的urlmanager可以让项目在访问的时候隐藏index.php，也可以以更优雅的urlrewrite方式来显示，但这一切需要一些配置，在apache上的配置上就相对比较简单，直接参考wordpress的官方配置就完了，但其实很久以来，一直都没有人写过nginx下的配置。大家都是在根据wordpress配置来更改的，比如lnmp项目中，就是：

不过，这两天在看官方guide的文档，原来这些问题，官方已经提供方案了：http://yii.neatcn.com/doc/guide/1.1/en/quickstart.apache-nginx-config#nginx

1. Apache

Yii is ready to work with a default Apache web server configuration. The .htaccess files in Yii framework and application folders restrict access to the restricted resources. To hide the bootstrap file (usually index.php) in your URLs you can add mod_rewrite instructons to the .htaccess file in your document root or to the virtual host configuration:

XML/HTML代码
RewriteEngine on  
  
# if a directory or a file exists, use it directly  
RewriteCond %{REQUEST_FILENAME} !-f  
RewriteCond %{REQUEST_FILENAME} !-d  
# otherwise forward it to index.php  
RewriteRule . index.php  

2. Nginx

You can use Yii with Nginx and PHP with FPM SAPI. Here is a sample host configuration. It defines the bootstrap file and makes yii catch all requests to unexisting files, which allows us to have nice-looking URLs.

XML/HTML代码
server {  
    set $host_path "/www/mysite";  
    access_log  /www/mysite/log/access.log  main;  
  
    server_name  mysite;  
    root   $host_path/htdocs;  
    set $yii_bootstrap "index.php";  
  
    charset utf-8;  
  
    location / {  
        index  index.html $yii_bootstrap;  
        try_files $uri $uri/ $yii_bootstrap?$args;  
    }  
  
    location ~ ^/(protected|framework|themes/\w+/views) {  
        deny  all;  
    }  
  
    #avoid processing of calls to unexisting static files by yii  
    location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {  
        try_files $uri =404;  
    }  
  
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000  
    #  
    location ~ \.php {  
        fastcgi_split_path_info  ^(.+\.php)(.*)$;  
  
        #let yii catch the calls to unexising PHP files  
        set $fsn /$yii_bootstrap;  
        if (-f $document_root$fastcgi_script_name){  
            set $fsn $fastcgi_script_name;  
        }  
  
        fastcgi_pass   127.0.0.1:9000;  
        include fastcgi_params;  
        fastcgi_param  SCRIPT_FILENAME  $document_root$fsn;  
  
        #PATH_INFO and PATH_TRANSLATED can be omitted, but RFC 3875 specifies them for CGI  
        fastcgi_param  PATH_INFO        $fastcgi_path_info;  
        fastcgi_param  PATH_TRANSLATED  $document_root$fsn;  
    }  
  
    location ~ /\.ht {  
        deny  all;  
    }  
}  

Using this configuration you can set cgi.fix_pathinfo=0 in php.ini to avoid many unnesessary system stat() calls.

 这是一篇很小的例子，事实上网上这些例子是超多的，不过由于我是要模拟metaweblog或者是wordpress的一些操作，那我就必须要先了解很多相关的背景。
不过这里只是模拟一些发布和读取的接口，稍作了解即可。
原文来自：用XML-RPC协议读写WordPress上的文章我这里只简要的摘取一部分。

WordPress提供了XML-RPC接口使得第三方的博客写作软件(如windows live writer等)可以与之通信来发布和修改博客。我们也可以在网站上使用这个接口做一些工作，例如：在网站首页显示最新的博客、在博客之外的页面上发表博 客文章、把博客与其他内容管理系统结合，等等。

一、开启XML-RPC支持

XML-RPC协议默认是未开启的，需要到WordPress管理后台的“设置–>撰写”里的“远程发布”给XML-RPC打上勾。其说明文 字为：启用 WordPress，Movable Type，MetaWeblog和Blogger 的 XML-RPC发布协议。

二、获取接口的信息

我们查看博客首页的源代码，在head中可以发现类似这样的link项

其中的"RSD"是“Really Simple Discovery”的意思，也就是说这是一个“简单的发现博客编辑接口”的地址。我们用浏览器直接访问这个地址就可以在其返回XML中获知博客的 ID(blogID，一般这个的值是“1”)以及它所支持的接口类型和接口地址。

三、API接口选择

WordPress提供了对Blogger API、metaWeblog API、Movable Type API以及其自身的WordPress API的支持。其中WordPress API最为丰富，提供了包括操作评论文章在内的各种各样的支持。Blogger API功能较少，基本上淘汰不用了；而metaWeblog API提供了常用的接口且参数比较简洁，用得较多一些。

四、例子代码

以下是使用Incutio的XML-RPC库和Blogger API发布文章的例子，其中IXR库也是Wordpress自身所用的库，可以在“wp-includes/class-IXR.php”找到。

以下是用XML-RPC for PHP库和metaWeblog接口发布文章的例子。要先下载phpxmlrpc库取出其中的xmlrpc.inc来用。 注意一定要加上：$GLOBALS['xmlrpc_internalencoding'] = ‘UTF-8′;这一句，否则不能正确处理中文。 另一段也是用phpxmlrpc库和metaWeblog接口发表文章的例子代码，该代码使用了返回类型为“phpvals”，这样可以直接用返回结果 的$r->val来获取文章ID号。

以下是读取最新一篇文章的例子代码：

Document status

This document was updated on 8/8/03, to incorporate all the RFCs related to the MetaWeblog API. The earlier version of the document is archived here. It has been reviewed by members of the MetaWeblog API mail list, and feedback has been incorporated.

On 8/24/03, I posted a last call for comments, and received several and incorporated some.

As of 8/26/03, this document is deployable. There may be changes, but they will be clearly documented, and will only clarify the spec, in no way will they change the format or protocol. It is now safe to deploy applications based on this spec.

What is the MetaWeblog API? 

The MetaWeblog API (MWA) is a programming interface that allows external programs to get and set the text and attributes of weblog posts. It builds on the popular XML-RPC communication protocol, with implementations available in many popular programming environments.

Relationship between MetaWeblog API and the Blogger API 

The MetaWeblog API is designed to enhance the Blogger API, which was limited in that it could only get and set the text of weblog posts. By the time MWA was introduced, in spring 2002, many weblog tools had more data stored with each post, and without an API that understood the extra data, content creation and editing tools could not access the data.

At the time of this writing, summer 2003, most popular weblog tools and editors support both the Blogger API and the MetaWeblog API.

Relationship between MetaWeblog API and RSS 2.0

The MetaWeblog API uses an XML-RPC struct to represent a weblog post. Rather than invent a new vocabulary for the metadata of a weblog post, we use the vocabulary for an item in RSS 2.0. So you can refer to a post's title, link and description; or its author, comments, enclosure, guid, etc using the already-familiar names given to those elements in RSS 2.0. Further since RSS 2.0 is extensible, so is the MetaWeblog API. We have designed conventions for representing attributes and namespaces in MWA.

Basic entry-points

There are three basic entry-points in the API:

metaWeblog.newPost (blogid, username, password, struct, publish) returns string

metaWeblog.editPost (postid, username, password, struct, publish) returns true

metaWeblog.getPost (postid, username, password) returns struct

The blogid, username, password and publish params are as in the Blogger API. newPost returns a string representation of the post id, again as defined by the Blogger API. The struct is where the juice is.

The struct 

In newPost and editPost, content is not a string, as it is in the Blogger API, it's a struct. The defined members of struct are the elements of <item> in RSS 2.0, providing a rich variety of item-level metadata, with well-understood applications.

The three basic elements are title, link and description. For blogging tools that don't support titles and links, the description element holds what the Blogger API refers to as "content."

Where an element has attributes, for example, enclosure, pass a struct with sub-elements whose names match the names of the attributes according to the RSS 2.0 spec, url, length and type.

For the source element, pass a struct with sub-elements, url and name.

For categories, pass an array of strings of names of categories that the post belongs to, named categories. On the server side, it's not an error if the category doesn't exist, only record categories for ones that do exist.

In getPost, the returned value is a struct, as with the Blogger API, but it contains extra elements corresponding to the struct passed to newPost and editPost.

The server must ignore all elements that it doesn't understand.

In a call to metaWeblog.newPost or metaWeblog.editPost, if the struct contains a boolean named flNotOnHomePage, then the post does not appear on the home page, and only appears on the specified category pages.

Request and response

Here's an example of a request and a response.

Here's the post that this request is getting info about.

metaWeblog.newMediaObject

metaWeblog.newMediaObject (blogid, username, password, struct) returns struct

The blogid, username and password params are as in the Blogger API.

The struct must contain at least three elements, name, type and bits.

name is a string, it may be used to determine the name of the file that stores the object, or to display it in a list of objects. It determines how the weblog refers to the object. If the name is the same as an existing object stored in the weblog, it may replace the existing object.

type is a string, it indicates the type of the object, it's a standard MIME type, like audio/mpeg or image/jpeg or video/quicktime.

bits is a base64-encoded binary value containing the content of the object.

The struct may contain other elements, which may or may not be stored by the content management system.

If newMediaObject fails, it throws an error. If it succeeds, it returns a struct, which must contain at least one element, url, which is the url through which the object can be accessed. It must be either an FTP or HTTP url.

metaWeblog.getCategories 

metaWeblog.getCategories (blogid, username, password) returns struct

The struct returned contains one struct for each category, containing the following elements: description, htmlUrl and rssUrl.

This entry-point allows editing tools to offer category-routing as a feature.

metaWeblog.getRecentPosts

metaWeblog.getRecentPosts (blogid, username, password, numberOfPosts) returns array of structs

Each struct represents a recent weblog post, containing the same information that a call to metaWeblog.getPost would return.

If numberOfPosts is 1, you get the most recent post. If it's 2 you also get the second most recent post, as the second array element. If numberOfPosts is greater than the number of posts in the weblog you get all the posts in the weblog.

Transmitting elements with attributes 

The members of the struct passed in newPost and editPost come from the elements of items in RSS 2.0. The most commonly used core elements have no attributes, so it's clear how to include them in the struct. However, some elements, such as source, enclosure and category, may have attributes and a value. Here are a simple set of rules for elements that have attributes and a value. Note that these rules do not apply to enclosure and source, which are provided for specifically above.

1. If an element has attributes, then represent the element with a struct, and include the attributes as sub-elements of the struct.

2. If an element has both attributes and a value, make the element a struct, include the attributes as sub-elements, and create a sub-element for the value with the name _value. Note that this means that no element can be passed through the API that has an attribute whose name is _value.

Transmitting elements from namespaces

RSS 2.0 allows for the use of namespaces. If you wish to transmit an element that is part of a namespace include a sub-struct in the struct passed to newPost and editPost whose name is the URL that specifies the namespace. The sub-element(s) of the struct are the value(s) from the namespace that you wish to transmit.

Comments 

The Blogger API provides a parameter called appkey that allows vendors to assign a key to developers so they can track and possibly limit usage of the API for certain tools. The MetaWeblog API doesn't specifically provide a parameter for an appkey. Applications that wish to transmit an appkey should add an element to the struct called appkey and set its value to the appkey that should be associated with the call.

Applications should use the fault-response scheme defined by XML-RPC. For example, trying to create, get, or edit a post without a valid username-password should generate a fault. Client applications should display the error string, as appropriate, to the user, for example, in a dialog, or in a server log.

Thanks

Thanks to Michael Bernstein for help editing this spec in summer 2003.

MetaWeblog发布协议
 
The MetaWeblog API is an application programming interface created by software developer Dave Winer that enables weblog entries to be written, edited, and deleted using web services.
 
The API is implemented as an XML-RPC web service with three methods whose names describe their function: metaweblog.newPost(), metaweblog.getPost() and metaweblog.editPost(). These methods take arguments that specify the blog author’s username and password along with information related to an individual weblog entry.
 
The impetus for the creation of the API in 2002 was perceived limitations of the Blogger API, which serves the same purpose. Another weblog publishing API, the Atom Publishing Protocol became an IETF Internet standard (RFC 5023) in October 2007.
 
Many blog software applications and content mangement systems support the MetaWeblog API, as do numerous desktop clients.
