我正在 Google App Engine 上编写一个小应用程序来更新我们用户个人资料中的图片。它需要用户名和图像，然后将配置文件放到那里，上传图像。这是我所拥有的:
import atom.data
import gdata.data
import gdata.contacts.client
import gdata.contacts.data
import cgi
import wsgiref.handlers
from google.appengine.api import users
from google.appengine.ext import webapp
email = 'admin@domain.com'
password = 'password'
domain = 'domain.com'
gd_client = gdata.contacts.client.ContactsClient(domain=domain)
gd_client.ClientLogin(email, password, 'photoUpdate')
class PicPage(webapp.RequestHandler):
def get(self):
self.response.out.write("""<html><head><title>Sasaki Photo Uploader</title>
<link type="text/css" rel="stylesheet" href="/stylesheets/form.css"></head>
<body>
<form action="/" enctype="multipart/form-data" method="post">
<div><label>Person Name</label></div>
<div><textarea name="name" rows="2" columns "60"></textarea></div>
<div><label>Image</label></div>
<div><input type="file" name="img"/></div>
<div><input type="submit" value="Upload" /></div>
</form>
</body>
</html>""")
def post(self):
person_name = self.request.get('name')
img_img = self.request.get('img')
profile_url = 'https://www.google.com/m8/feeds/photos/profile/domain.com/%s' % person_name
media_object = img_img
print(profile_url)
profile = gd_client.GetProfile(profile_url)
print(profile)
gd_client.ChangePhoto(media_object, profile)
self.redirect('/')
def main():
application = webapp.WSGIApplication(
[('/', PicPage)
],
debug=True)
wsgiref.handlers.CGIHandler().run(application)
if __name__=="__main__":
main()
当我运行它时它返回错误:
Traceback (most recent call last):
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\ext\webapp\_webapp25.py", line 703, in __call__
handler.post(*groups)
File "C:\GAE_Local_Files\picupload\sasakipic.py", line 40, in post
profile = gd_client.GetProfile(profile_url)
File "C:\GAE_Local_Files\picupload\gdata\contacts\client.py", line 375, in get_profile
auth_token=auth_token, **kwargs)
File "C:\GAE_Local_Files\picupload\gdata\client.py", line 652, in get_entry

version=get_xml_version(self.api_version))
File "C:\GAE_Local_Files\picupload\atom\core.py", line 520, in parse
tree = ElementTree.fromstring(xml_string)
File "<string>", line 106, in XML
ParseError: not well-formed (invalid token): line 1, column 0
我不确定这是否是因为我将个人资料网址作为字符串传递或上传图片错误。任何建议，非常感谢。
编辑 添加了完整的堆栈跟踪
最佳答案
嗯，答案在于我在编辑中指出的问题。那一行:
profile = gd_client.GetProfile(profile_url)
正在尝试查询位于配置文件中的图片，但如果它不存在就会中断，所以我编辑 try 语句以直接传递配置文件 url:
try:
gd_client.ChangePhoto(media_object, profile_url)
效果很好。这是一个很棒的小工具，可以使用 App Engine 更新图片，您甚至不必上传它，只需在 App Engine 测试服务器上本地运行即可。我想尝试添加一些功能，例如图像裁剪或上传前调整大小，大图像在联系人个人资料页面上看起来不错，但在聊天图像中可能会变形。
