博客园与Hexo同步发布的方法

介绍

之前想到:博客一次写作,多地发布,于是边有了这个项目:选择性同步Hexo与博客园。

GitHub链接:https://github.com/JeffersonQin/hexo-cnblogs-sync

魔改Next模板,增加标题栏提醒

themes/next/layout/_macro/post.swig中,选择合适的地方加入:

1
2
3
4
5
6
7
8
9
{% if post.cnblogs %}
<br>
<span class="post-meta-item">
<span class="post-meta-item-icon">
<i class="fas fa-rss"></i>
</span>
<span class="post-meta-item-text" id="cnblogs_sync_text"><a href="https://www.cnblogs.com/jeffersonqin/">博客园</a> 同步已开启</span>
</span>
{% endif %}

这样的话,如果要同步,只需要控制文件头就可以了,类似于本文:

BS4微调Hexo生成的HTML

先扫描一遍public文件夹里的输出文件:

orig_dir = "../public/"
repo_dir = "../public_cnblogs/"
ignore_files = ["../public/index.html"]
ignore_dirs = ["../public/page/", "../public/archives"]
# Filtering the files needed to post
for root, dirs, files in os.walk(orig_dir):
for file in files:
try:
file_name = str(file)
file_path = os.path.join(root, file)
file_dir = root.replace('\\', '/')
file_path = file_path.replace('\\', '/')

flag = True

for ignore_dir in ignore_dirs:
if file_dir.startswith(ignore_dir):
flag = False
break
for ignore_file in ignore_files:
if file_path == ignore_file:
flag = False
break

if (file_name == 'index.html' and flag):
index_files.append(file_path)
print('\033[42m\033[37m[LOGG]\033[0m File Detected:', file_path)

except Exception as e:
raise e

print('\033[44m\033[37m[INFO]\033[0m File Detection Ended.')

然后使用BS4来操作HTML和CSS

# Filter the articles that are to be synced

resource_dict = {}

for index_file in index_files:
post_body = ""
with open(index_file, 'r', encoding='utf-8') as f:
html_doc = f.read()
soup = BeautifulSoup(html_doc, "html.parser")
check_msg = soup.select('span[id=cnblogs_sync_text]')
if (len(check_msg) == 0): continue
post_body_list = soup.select('div[class=post-body]')
if (len(post_body_list) == 0): continue
print('\033[42m\033[37m[LOGG]\033[0m Target Detected:', index_file)
for child in soup.descendants:
if (child.name == 'img'):
if ('data-original' in child.attrs and 'src' in child.attrs):
child['src'] = 'https://gyrojeff.moe' + child['data-original']
elif ('src' in child.attrs):
child['src'] = 'https://gyrojeff.moe' + child['src']
if (child.name == 'a'):
if ('href' in child.attrs):
if (str(child['href']).startswith('/') and not str(child['href']).startswith('//')):
child['href'] = 'https://gyrojeff.moe' + child['href']
post_body = soup.select('div[class=post-body]')[0]
math_blocks = post_body.select('script[type="math/tex; mode=display"]')
for math_block in math_blocks:
math_string = str(math_block).replace('<script type="math/tex; mode=display">', '<p>$$').replace('</script>', '\n$$</p>')
math_block.replace_with(BeautifulSoup(math_string, 'html.parser'))
save_dir = os.path.join(repo_dir, index_file[len(orig_dir):-len("index.html")])
if not os.path.exists(save_dir): os.makedirs(save_dir)
copyright_div = str(soup.select('div[class=my_post_copyright]')[0])
with open(save_dir + 'index.html', 'w', encoding='utf-8') as f:
f.write(header + '\n' + copyright_div + '\n' + str(post_body))
tags = soup.select('div[class=post-tags]')
tags_text = []
if len(tags) != 0:
tags_div = tags[0].select('a')
if len(tags_div) > 0:
for tag in tags_div:
tags_text.append(tag.contents[1][1:])

resource_dict[save_dir + 'index.html'] = {
'tags': tags_text,
'title': soup.select('meta[property="og:title"]')[0]['content']
}
print('\033[44m\033[37m[INFO]\033[0m File Generated:', save_dir + 'index.html')

print('\033[44m\033[37m[INFO]\033[0m File Generation Ended.')

上面的大多数代码基本上都需要具体情况具体分析,分析生成的HTML和我们需要的代码之间的关系。值得注意的是,math_blocks的那一段代码是巧妙地解决数学公式mathjax只渲染到<script>的问题的。(直接匹配再用$$$$替换,这样可以直接使用博客园的markdown进行渲染,毕竟markdown可以兼容html)这里面,header是我根据这套Next主题自己扒的,源码在我的GitHub上有(链接在本文文末)

MetaWeblog发布博文

博客园可以使用MetaWeblog接口,不过categories有点问题,不太能使用。

原作:https://github.com/1024th/cnblogs_githook

但是在删除接口方面存在问题,这里进行了更改。

注意

如果发现中文转码出现问题,记得运行下面这行命令:

git config --global core.quotepath false
