一、上传资源

首先我们解析 CSDN 上传请求，这里随便上传一张图片，观察请求；

请求由三部分组成，分别是：1. 获取存储位置和签名验证信息；2. 利用签名等验证信息上传文件；3. 获取文件信息并显示；

仔细观察两个请求，upload 请求是 GET ，csdn 请求是 POST，其结果很明显 csdn 请求是主体，仔细观察 csdn 的参数，可以所有参数都可以利用 upload 的返回结果得到；

那么接下来我们开始构造 upload 请求

python 复制代码

import requests

headers = {
    'accept': '*/*',
    'accept-language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
    'content-type': 'application/json',
    'cookie': '', # 输入自己的cookies
    'origin': 'https://editor.csdn.net',
    'priority': 'u=1, i',
    'referer': 'https://editor.csdn.net/',
    'sec-ch-ua': '"Not/A)Brand";v="8", "Chromium";v="126", "Microsoft Edge";v="126"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
    'sec-fetch-dest': 'empty',
    'sec-fetch-mode': 'cors',
    'sec-fetch-site': 'same-site',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36 Edg/126.0.0.0',
}

params = {
    'type': 'blog',
    'rtype': 'markdown',
    'x-image-template': '',
    'x-image-app': 'direct_blog',
    'x-image-dir': 'direct',
    'x-image-suffix': 'png',
}

url = 'https://imgservice.csdn.net/direct/v1.0/image/upload'
response = requests.get(url, params=params, headers=headers)

# 获得数据
upload_data = response.json()

得到 json 内容如下，通过比较该内容下 expire 和 time 库下的 time.time() * 1000，再根据英文名可以推断，expire 表示的是上传文件这一请求的失效时间，即 csdn 请求的最晚成功时间；

json 复制代码

{'code': 200,
 'data': {'accessId': 'LTAI5tK31AXMAqwzaX1wn4hH',
          'callbackUrl': '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',

          'signature': '2hRKp5YO3epBJe5+Qt7Ngi7P/y4='},
 'message': None,
 'msg': 'success'}

下面利用 upload 得到的请求来构造 csdn 请求；

python 复制代码

import requests
from requests_toolbelt.multipart.encoder import MultipartEncoder

def get_file(file_path):
	"""获取文件的二进制数据"""
    with open(file_path, mode='rb') as f:
        binary_data = f.read()
    return binary_data

headers = {
    'Accept': 'application/json, text/javascript, */*; q=0.01',
    'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
    'Connection': 'keep-alive',
    'Origin': 'https://editor.csdn.net',
    'Referer': 'https://editor.csdn.net/',
    'Sec-Fetch-Dest': 'empty',
    'Sec-Fetch-Mode': 'cors',
    'Sec-Fetch-Site': 'cross-site',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36 Edg/126.0.0.0',
    'sec-ch-ua': '"Not/A)Brand";v="8", "Chromium";v="126", "Microsoft Edge";v="126"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
}

success_action_status = '200'

# upload 请求中获取到的数据
key = upload_data['data']['filePath']
policy = upload_data['data']['policy']
OSSAccessKeyId = upload_data['data']['accessId']
signature = upload_data['data']['signature']
callback = upload_data['data']['callbackUrl']

# 上传的图片位置，
file = get_file('') # 输入需要上传文件的位置

files = {
    'key': (None, key),
    'policy': (None, policy),
    'OSSAccessKeyId': (None, OSSAccessKeyId),
    'success_action_status': (None, '200'),
    'signature': (None, signature),
    'callback': (None, callback),
    'file': ('image.png', file, 'image/png'),
}

url = 'https://csdn-img-blog.oss-cn-beijing.aliyuncs.com/'
response = requests.post(url, headers=headers, files=files)

print(response.text)

得到 Json 数据如下

json 复制代码

{'code': 200,
 'data': {'hostname': 'https://img-blog.csdnimg.cn/',
  'imageUrl': 'https://img-blog.csdnimg.cn/direct/97c5610606c140afb474800403140ea3.png',
  'width': '1138',
  'targetObjectKey': 'direct/97c5610606c140afb474800403140ea3.png',
  'x-image-suffix': 'png',
  'height': '239'},
 'msg': 'success'}

在其中 imageUrl 就表示上传的图片地址，同时，图片格式有许多种，面对不同的图片格式，在尝试观察后发现只需要修改 upload 请求中 parms 中的 x-image-suffix，csdn 请求中 files 中的 file；

整合得到完整上传类如下：

python 复制代码

二、替换 MD 中的引用文件为在线链接

首先，肯定是整体替换而不是单个替换，因此我们的流程为：1. 上传所有文件，直到所有的文件都上传成功；2. 替换所有文件；

首先提取出 Markdown 中所有的图片信息，一般来说图片信息都在两个中括号之间 ![[ img_pic ]]，使用 re 正则提取，代码如下；

python 复制代码

import re

file_path = 'C:/Users/Administrator/Documents/Obsidian Vault/UE开发/My FirstGame Tutorial.md'

with open(file_path, mode='r', encoding='utf-8') as f:
    markdown_text = f.read()

image_lst = re.findall(r'(!\[\[.*\]\])', markdown_text)
posterior_image_lst = [item[3:-2] for item in image_lst]

提取出所有的 img_pic 后，我们需要在根目录下寻找文件，一般来说在 Markdown 中文件名是不重复的；

python 复制代码

import os
from pathlib import Path

def get_target_image_path(target_path):
    walk_path = 'C:/Users/Administrator/Documents/Obsidian Vault/'
    for root, floders, files in os.walk(walk_path):
        for file in files:
            if file == target_path:
                return Path(root) / file

get_target_image_path(posterior_image_lst[0])

获取到了绝对位置后，我们可以将图片上传，在检查图片全部都上传完毕后，我们就可以替换 ![[ img_pic ]]

python 复制代码
