使用metaweblog API实现通用博客发布 之 API测试
使用metaweblog API实现通用博客发布 之 API测试
使用博客比较少,一则是文笔有限,怕写出的东西狗屁不通,有碍观瞻, 二则是懒,很讨厌要登录到网站上写东西,也没有那么多时间(借口)。个人最喜欢用于记录的工具是Zim https://zim-wiki.org/ ,记录东西超级方便,可惜只支持PC版本, 记录的东西可以到处为MarkDown 格式,非常方便(你现在看到的这篇就是用Zim写的)。
无意间看到Vs Code上有博客园的插件,作为程序员,顺手google/百度了一下,原来通用博客都支持使用metaweblog API来访问,还支持直接发布markdown 格式,简直不要太好。 找了找2年前注册的博客源账号,用来测试一下。
发挥典型中国程序员的拿来主义精神,经过goolgle/百度一番搜索,参考以下文档进行API测试,在此表示感谢!!

1 在哪里找API说明
在博客设置最的最末端,有MetaWeblog 的访问地址链接
点击进入页面,有metaweblog API 的详细说明
具体内容不赘述了。
2 测试API
使用python3 进行API测试,直接上代码:
#encoding = utf-8
#!/bin/sh python3
import xmlrpc.client as xmlrpclib
import json
'''
配置字典:
type | description(example)
str | metaWeblog url, 博客设置中有('https://rpc.cnblogs.com/metaweblog/1024th')
str | appkey, Blog地址名('1024th')
str | blogid, 这个无需手动输入,通过getUsersBlogs得到
str | usr, 登录用户名
str | passwd, 登录密码
str | rootpath, 博文存放根路径(添加git管理)
'''
'''

#以上是对API的简单封装,万事具备,开始测试
### 2.1 获取分类
```python
import core.metablogclient as blogclient
client = blogclient.MetablogClient('blog_config.json')
client.readConfig()
catLst = client.getCategories()
print(catLst)
[{'description': '[发布至博客园首页]', 'htmlUrl': '', 'rssUrl': '', 'title': '[发布至博客园首页]', 'categoryid': '0'},
{'description': '[Markdown]', 'htmlUrl': '', 'rssUrl': '', 'title': '[Markdown]', 'categoryid': '-5'}...]
获取了所有的分类信息,其中我在网站上自建了一个随笔分类,也可以获取到
2.2 新建分类
import core.metablogclient as blogclient
client = blogclient.MetablogClient('blog_config.json')
client.readConfig()
catid = client.newCategory({
"name": "[随笔分类]测试分类",
"slug": "",
"parent_id": 0,
"description": "测试建立一个随笔子分类"
})
print("新建分类:", catid)
新建分类: 1536823
但是在博客园网站上无法看到这个分类,使用获取分类再次测试,也无法获取到该分类,使用该分类发布博客,也是无
效的,所以我想__根据年月自动分类__的想法就泡汤啦
2.3 拉取现有博文
import core.metablogclient as blogclient
client = blogclient.MetablogClient('blog_config.json')
client.readConfig()
posts = client.getRecentPosts(9999)
print(posts)
[{'dateCreated': <DateTime '20190829T11:21:00' at 0x2a80990>, 'description': '<p>测试</p>', 'title': '测试', 'enclosure': {'length': 0},
'link': 'https://www.cnblogs.com/robert-9/p/11428668.html', 'permalink': 'https://www.cnblogs.com/robert-9/p/11428668.html',
'postid': '11428668', 'source': {}, 'userid': '-2'}]
正确拉取现有博文,通过API文档,发现无法获取博文是否处于发布状态,这是一个遗憾
2.4 发布博文
import core.metablogclient as blogclient
import datetime
client = blogclient.MetablogClient('blog_config.json')
client.readConfig()
postid = client.newPost({
"time": datetime.datetime.now(),
"title": "metaweblog API随笔发布",
"description": "##metaweblog API随笔发布\n测试\n",
"categories": ["[Markdown]"],
"mt_keywords": "metaweblog;python"
}, False)
print('发布随笔:', postid)
测试发布成功,并能在网站上看到该随笔, 如果想发布为文章,日志或新闻,加入必要的分类即可。
2.5 上传图片
import datetime
import base64
import core.metablogclient as blogclient
client = blogclient.MetablogClient('blog_config.json')
client.readConfig()
with open('abc.png', 'rb') as f:
bs64_str = base64.b64encode(f.read())
url = client.newMediaObject({
"bits": bs64_str,
"name": "abc.png",
"type": "image/png"
})
print(url)
{'url': 'https://img2018.cnblogs.com/blog/1211514/201908/1211514-20190829114435333-814710358.png'}
测试成功, 这样就可以在上传Markdown 格式之前,自动将本地的图片上传到服务器上了。

======================================================
上面的github中的 cnblogs_githook 我也一起贴到这里,方便查看:
cnblogs_githook
基于rpcxml协议,利用githook,在commit时自动发布本地markdown文章到博客园。
使用说明
本脚本用python3
编写,请配置好运行环境。
- 第一次使用前先把
./hooks/commit-msg
文件复制到./.git/hooks/
中。 - 运行
cnblogs.py
:- 程序有一个可选参数。
config
设置博客信息。download
下载文章。
- 第一次运行
cnblogs.py
时默认选择config
参数,设置博客信息。 - 此后每次运行程序时,
./articles/*.md
将被上传到博客并发布;./unpublished/*.md
将被上传到博客,但不发布(并标注分类“unpublished”)。文章均以文件名为题,且不发布的文章。如果博客中已经存在同名文章,将替换其内容!
- 程序有一个可选参数。
- 编辑
./articles/
,./unpublished/
中markdown文件,在本地git仓库commit
更改,自动运行./cnblogs.py
(需要使用终端命令才能查看返回信息)。
注意事项/已知Bug
- 本程序不保证稳定性,为防止数据丢失,建议使用前预先备份博客。
- clone仓库不能下载
.git
文件夹,因此需要手动复制调用cnblogs.py
的脚本./hooks/commit-msg
到.git
。 - 由于metaWeBlog本身没有提供查看文章是否已发布的接口,所有使用“unpublished”分类标注未发布文章。也就是说,当执行
python cnblogs.py download
命令时,博客中没有发布也没有“unpublished”分类的文章也会存到./articles/
,下次运行时将被自动发布。 - 由于接口不允许将已经发布的文章设置为未发布,所以若
./unpublished/
内的文章在博客内有同名文章时不会被上传。
