【问题描述】:
我只是按照 GAE 的文档 (https://developers.google.com/appengine/docs/python/blobstore/#Python_Uploading_a_blob) 编写上传处理程序来上传 blobstore,当我在计算机上选择一个文件并单击 HTML 页面上的提交按钮时,它会显示 'The url "/upload" does not match any处理程序。 任何 cmets 表示赞赏。
class MainPage(webapp2.RequestHandler):
def get(self):
self.response.headers['Content-Type'] = 'text/html; charset=utf-8'
upload_url = blobstore.create_upload_url('/upload')
logging.info(upload_url)
self.response.out.write('<html><body>')
self.response.out.write('<form action="%s" method="POST" enctype="multipart/form-data">' % upload_url)
self.response.out.write("""Upload File: <input type="file" name="file"><br> <input type="submit"
name="submit" value="Submit"> </form></body></html>""")
class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
logging.info('Upload handler')
upload_files = self.get_uploads('file') # 'file' is file upload field in the form
blob_info = upload_files[0]
logging.info(upload_files)
self.redirect('/serve/%s' % blob_info.key())
class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):
def get(self, resource):
resource = str(urllib.unquote(resource))
logging.info(resource)
blob_info = blobstore.BlobInfo.get(resource)
self.send_blob(blob_info)
application = webapp2.WSGIApplication([
('/', MainPage),
('/upload', UploadHandler),
('/serve/([^/]+)?', ServeHandler),
], debug=True)
[更新1] 单击提交按钮后,我检查了 dev-server Blobstore 查看器,我发现文件已上传到那里,但是,我的 chrome 浏览器仍然显示'The url "/upload" does not match any handlers.'。这是为什么?
【问题讨论】:
-
app.yaml 的处理程序部分有什么?有什么映射/上传到这个 python 模块的吗?
-
@Greg app.yaml 只有一个处理程序。 - url:/脚本:AppWS.application
-
还有一件奇怪的事情,在开发服务器日志中,没有任何 logging.info('Upload handler') 信息,似乎我的 UploadHandler 没有被调用,但是文件已上传到开发服务器blobstore,上传 URL 始终是 (localhost:8080/_ah/upload/…) 发生了什么?
