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.

在看代码的时候看到了这个offsetParent也就顺便找了一下资料：

然后找了一段代码进行测试：

这个时候就象上面的说明所说的，在firefox和webkit核心下两者都返回了“body”，然而：

于是我在div的id="b"的style里加入了position:absolute，然后再测试，果然就返回了DIV。

小家伙现在稀奇古怪的想法很多了

这是来自perfgeeks.com的一篇文章，介绍了一些常见的工具，还有一个脚本。
在用YII框架的时候，我用的是hightman写的一个cssmin的插件，可以直接把css和js进行合并到一个文件。对于图片，我都是把这个艰巨的任务交给前端，由他们完成，至于他们用什么样的png或者gif之类的优化软不不是我关心的了。OK，先上文章
来源网址是是：http://www.perfgeeks.com/?p=660
内容如下：

更小的静态资源(js、css、png、gif)，意味着更少的网络传送时间。构建的时候，可以把这些静态资源进行压缩优化(不像gzip/deflate压缩)，使之更小化。有很多相应的开源工具帮助你完成这项工作。

javascript

• Google Closure Compiler
• UglifyJS
• YUI Compressor
• ShrinkSafe
• 其它,比如JSMIN

Node.js、jQuery1.5开始使用UglifyJS，UglifyJS压缩比YUI Compressor更小、比Google Closure Compiler更安全。尽管如此，但UglifyJS需要部署NodeJS环境，所以我们还是选择使用Google Closure Compiler

style(css)

• CSSTidy
• YUI Compressor
• Yslow/Google Page Speed

CSSTidy和YUI Compressor都很棒，我们还是选择老牌的YUI Compressor，因为我们更熟悉它，它也能够满足我们的需求。

png8/gif图片

• Optipng
• AdvanceCOMP(advpng、advdef)
• ImageMagic(mogrify、identify、convert)
• Pngcrush
• Pngout
• gifsicle
• jpegtran

任何大一点的网站页面都会使用到不少图片，压缩优化图片很有必要。选择什么样的图片格式，决定了怎么去压缩图片。一般而言，只要是非动画图片，我们 推荐png8，即便是颜色很少的小图片(尽管这样的图片gif有更高压缩性，但应该使用css sprites)。Pngout没有开放源码，仅能在Window NT平台使用，所以我们并不考滤使它。Pngcrush虽然很好用，但是optipng、advpng以及advdef结合使用能把图片压缩得更小，所以 我们选择optipng、advpng以及advdef压缩优化PNG图片。 Optipng压缩优化图片、而advdef则优化压缩算法。

构建脚本

发布产品的时候，我们希望构建前端资源，包括压缩优化、合并等等。构建应该尽量满足:
1.整个过程是自动的，不需要人工介入
2.所有的操作都是安全的
3.免费的命令行工具

我们这里应用bash写了一个简版的部署脚本，能够简单地应付中小型网站静态资源发布。

执行结果如下

总结

1.UglifyJS压缩比YUI Compressor更小，比Google Closure Compiler更安全。不想冒险，还是应该选择UglifyJS。若想最小化，可以选择Google Closure Compiler
2.YUI Compressor压缩css文件。但CSSTidy也很不错
3.optipng -o3 *.png |advpng -z -4 *.png |advdef -z -4 *.png 将最大化压缩优化png图片
4.网页尽量使用png格式图片，并且压缩优化它，使之最优

纠结，原文中的代码是有配色的，但是COPY过来就没有配色了，而自带的配色没有bash的配色。所以。。。将就点看了，或者看原文吧：http://www.perfgeeks.com/?p=660
