python2转python3 poster模块求指点迷津
公众号开发文档是python2的内容，现在用python3开发，安装了poster3模块，但是不会用# 报错信息
Traceback (most recent call last):

mediaType = "image"
myMedia.upload(accessToken, filePath, mediaType)
求大神指点迷津，不胜感激 没看代码，我光看报错，意思是字节类型没有encode，字节只有decode成其他类型的，比如字符串。
要么你方法用错了，要么你方法的参数弄错了 from basic import Basic

import poster3
from poster3.streaminghttp import register_openers
class Media(object):

python的库还真是多,
没用过poster3 不过查了下api
https://github.com/EvanDarwin/poster3
from poster import Form
form = Form()
# Add an image object
form.add_file('media', open('upload.jpg', 'rb'))
content, headers = form.encode()
url = '要上传图片的url'
request = urllib.request.Request(url, content, headers)
urlResp = urllib.request.urlopen(request)
我一般用requests上传文件
imports requests
url = '上传地址'
file = open('123.jpg', "rb"))
resp = requests.post(url,files=file)
print(resp.text) ufo0033 发表于 2021-3-6 10:59

感谢指点，有request上传的时候报错说要解包的值太多{:1_907:}Traceback (most recent call last):

第一个解决方法模块还是有问题，因为poster只支持python2，所以安装的是poster3，里边没有Form
Traceback (most recent call last):
File "media.py", line 5, in <module>
from poster import Form
ModuleNotFoundError: No module named 'poster'
Traceback (most recent call last):
File "media.py", line 5, in <module>
from poster3 import Form
ImportError: cannot import name 'Form' from 'poster3' (/usr/local/lib/python3.8/dist-packages/poster3/__init__.py)
非常感谢您的热心 本帖最后由 ufo0033 于 2021-3-6 12:03 编辑
