Pytumblr调用create_photo时报TypeError：预期路径对象而非BufferedReader

问题描述 #

调用pytumblr的create_photo接口上传图片时触发TypeError，错误提示：

TypeError: expected str, bytes or os.PathLike object, not BufferedReader

最初怀疑是博客访问变量错误，替换为博客URL后问题仍存在，参考同类问题未得到有效解决，且报错结尾为BufferedReader，与常见的io.BufferedReader略有差异。

原实现代码 #

import pytumblr
import os

# Authenticate via Tumblr API
client = pytumblr.TumblrRestClient(
    "consumer-key",
    'consumer-secret',
    'oauth-key',
    'oauth-secret',
)

# Set the directory containing the photos to upload
photo_directory = 'dir-to-photos'

# Iterate through the files in the directory
for filename in os.listdir(photo_directory):
    # Upload the photo to Tumblr
    photo = open(photo_directory +"/"+ filename, 'rb')
    response = client.create_photo('phantom-cass.tumblr.com', data=photo, tags=['photo dump'])
    photo.close()

    response = client.create_photo('blog-name.tumblr.com', data=photo, tags=['photo dump'])

    files = {'data': open(params['data'], 'rb')}

TypeError: expected str, bytes or os.PathLike object, not BufferedReader

问题分析 #

从报错堆栈的关键行files = {'data': open(params['data'], 'rb')}可以看出：pytumblr库的create_photo接口要求data参数传入文件路径字符串，而非已经打开的BufferedReader对象。你提前打开了文件并传递句柄，库内部还会尝试调用open()去处理这个句柄，因此触发类型错误。

解决方案 #

直接传递文件的完整路径字符串给data参数，无需提前打开文件。同时使用os.path.join()拼接路径，避免跨平台路径分隔符问题。

修正后的代码 #

import pytumblr
import os

# Authenticate via Tumblr API
client = pytumblr.TumblrRestClient(
    "consumer-key",
    'consumer-secret',
    'oauth-key',
    'oauth-secret',
)

# Set the directory containing the photos to upload
photo_directory = 'dir-to-photos'

# Iterate through the files in the directory
for filename in os.listdir(photo_directory):
    # 用os.path.join拼接完整文件路径，适配不同操作系统
    photo_path = os.path.join(photo_directory, filename)
    # 直接传递文件路径给data参数
    response = client.create_photo('phantom-cass.tumblr.com', data=photo_path, tags=['photo dump'])

说明 #

• 移除了手动打开文件的代码，让pytumblr库内部自行处理文件的打开与读取逻辑
• os.path.join()会根据操作系统自动选择正确的路径分隔符（Windows用\，Linux/macOS用/），避免路径拼接错误
