# PDF2MD for RAG

|
||
## 使用api_key使用PDF2MD
|
||
|
||
通过使用doc2x的库，实现将pdf文件转换为结构化md文档。
|
||
|
||
通过代码调用(需要提供api_key)：
|
||
|
||
~~~python
|
||
import requests as rq
|
||
import json
|
||
import os
|
||
import zipfile
|
||
|
||
class PDF2MD:
|
||
def __init__(self, api_key):
|
||
self.api_key = api_key
|
||
self.url = "https://api.doc2x.noedgeai.com/api/v1/pdf"
|
||
self.export_url = "https://api.doc2x.noedgeai.com/api/export"
|
||
|
||
def convert(self, filepath, to="md"):
|
||
filename = os.path.splitext(os.path.basename(filepath))[0]
|
||
|
||
res = rq.post(self.url, files={"file": open(filepath, "rb")}, headers={"Authorization": "Bearer " + self.api_key}, stream=True)
|
||
|
||
if res.status_code == 200:
|
||
txt_path = filename + ".txt"
|
||
with open(txt_path, "w", encoding="utf-8") as f:
|
||
for line in res.iter_lines():
|
||
if len(line) > 0:
|
||
decoded_line = line.decode("utf-8")
|
||
f.write(decoded_line + "\n")
|
||
print(decoded_line)
|
||
|
||
uuid = json.loads(decoded_line.replace("data: ", ''))['uuid']
|
||
print(uuid)
|
||
|
||
if to == "md" or to == 'latex':
|
||
path = filename + '.zip'
|
||
elif to == 'docx':
|
||
path = filename + '.docx'
|
||
|
||
export_url = self.export_url + "?request_id=" + uuid + "&to=" + to
|
||
res = rq.get(export_url, headers={"Authorization": "Bearer " + self.api_key})
|
||
|
||
if res.status_code == 200:
|
||
with open(path, "wb") as f:
|
||
f.write(res.content)
|
||
print("下载成功,存入:", path)
|
||
|
||
if to == "md" or to == 'latex':
|
||
zip_file = zipfile.ZipFile(path)
|
||
|
||
# 创建以原始文件名命名的文件夹
|
||
if not os.path.exists(filename):
|
||
os.mkdir(filename)
|
||
|
||
# 解压到该文件夹内
|
||
for names in zip_file.namelist():
|
||
zip_file.extract(names, filename)
|
||
zip_file.close()
|
||
|
||
# 找到解压后的md文件
|
||
for file in os.listdir(filename):
|
||
if file.endswith(".md"):
|
||
extracted_md = os.path.join(filename, file)
|
||
break
|
||
|
||
# 重命名md文件
|
||
new_md_name = os.path.join(filename, filename+'.md')
|
||
os.rename(extracted_md, new_md_name)
|
||
print("解压并重命名md文件为:", new_md_name)
|
||
|
||
else:
|
||
print(format("[ERROR] status code: %d, body: %s" % (res.status_code, res.text)))
|
||
else:
|
||
print(format("[ERROR] status code: %d, body: %s" % (res.status_code, res.text)))
|
||
|
||
|
||
|
||
def main():
|
||
api_key = "sk-xxx"
|
||
filepath = r"test.pdf"
|
||
converter = PDF2MD(api_key)
|
||
converter.convert(filepath, to="md")
|
||
|
||
|
||
if __name__ == "__main__":
|
||
main()
