问题描述

通过请求，我收到以下 PDF 文档，我想保存：

我尝试通过以下方式保存它：

response = requests.get(url, headers=self.get_authentication_header(path=path, method="GET"))
with open("my_file.pdf", 'wb') as f:
    f.write(response.content)
    f.close()

哪个有效，但pdf已损坏。如何保存此 PDF？

解决方案

您尝试将 json 写入文件。你应该解析你的json并写一些类似的东西

data = response.json()["data"]
with open("my_file.pdf", 'wb') as f:
    f.write(base64.b64decode(data))
