如何将图像从url上传到Blobstore？(How to upload image from url to Blobstore?)

 如果blobstore blob，Google App Engine文件API现在支持编程创建。 
 

 我试图通过http获取图像并将其存储到blobstore来尝试这个： 
 

    file_name = files.blobstore.create(mime_type='image/jpeg')
    image = urllib2.urlopen(url)
    with files.open(file_name, 'a') as f:
        f.write(image)  # LINE 142

    files.finalize(file_name)   
    blob_key = files.blobstore.get_blob_key(file_name) 

 

 此代码抛出错误： 
 

  File "/Users/willmerydith/repos/spam/admin.py", line 142, in post
    f.write(image)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py", line 364, in write
    self._make_rpc_call_with_retry('Append', request, response)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py", line 472, in _make_rpc_call_with_retry
    _make_call(method, request, response)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py", line 229, in _make_call
    rpc.check_success()
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_stub_map.py", line 558, in check_success
    self.__rpc.CheckSuccess()
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_rpc.py", line 156, in _WaitImpl
    self.request, self.response)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_stub.py", line 80, in MakeSyncCall
    if request.ByteSize() > self.__max_request_size:
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file_service_pb.py", line 1923, in ByteSize
    n += self.lengthString(len(self.data_))
AttributeError: addinfourl instance has no attribute '__len__'

 

 我怀疑它正在破裂，因为我超出了尺寸限制。 这是由于我将图像写入blobstore的方式吗？ Blobstores的大小限制为2 GB，我测试的图像小于200-300 KB。 

The Google App Engine Files API now supports programmatic creation if blobstore blobs.
 

I'm trying this out by attempting to fetch an image over http and store it to the blobstore:
 

    file_name = files.blobstore.create(mime_type='image/jpeg')
    image = urllib2.urlopen(url)
    with files.open(file_name, 'a') as f:
        f.write(image)  # LINE 142

    files.finalize(file_name)   
    blob_key = files.blobstore.get_blob_key(file_name) 

 

This code is throwing the error:
 

  File "/Users/willmerydith/repos/spam/admin.py", line 142, in post
    f.write(image)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py", line 364, in write

    _make_call(method, request, response)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py", line 229, in _make_call
    rpc.check_success()
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_stub_map.py", line 558, in check_success
    self.__rpc.CheckSuccess()
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_rpc.py", line 156, in _WaitImpl

  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_stub.py", line 80, in MakeSyncCall

    n += self.lengthString(len(self.data_))
AttributeError: addinfourl instance has no attribute '__len__'

 

I suspect it is breaking because I am exceeding a size limit. Is that due to the way I am writing the image to the blobstore? The size limit for Blobstores is 2 GB, and the images I am testing are less than 200-300 KB.

 你需要改变两件事： 
 

     
 
  1.  应用line-height: 30px; 到<li>元素。 这是因为您的图像高度为30像素。 
    2.  
 
  2.  应用vertical-align: bottom; 到你的<span>与图像。 这是将图像与文本垂直对齐。 
    3.  

 

 此外，这将破坏行之间的填充，因此您可能还想为<li>元素添加一些底部填充/边距。 
 

 结果代码： 
 

 第1步 ： 
 

.footer .footer-contact-list li {
  position: relative;
  line-height: 30px; /* add this */
  /* here you may also add some bottom margin/padding */
}

 

 第2步 ： 
 

.footer .footer-contact-list li span {
  height: 30px;
  width: 30px;
  border-radius: 50%;
  background: #a32020;
  display: inline-block;
  margin: 0 5px 0 0;
  position: relative;
  vertical-align: bottom; /* add this */
}


You need to change two things:
 

     
 
  1. Apply line-height: 30px; to the <li> element. This is because your image is 30px in height.
    2.  
 
  2. Apply vertical-align: bottom; to your <span> with the image. This is to vertically align your image with the text.
    3.  

 

Also, this will break your padding between the lines, so you may want to add some bottom padding/margin to <li> elements as well.
 

The resulting code:
 

Step 1:
 

.footer .footer-contact-list li {
  position: relative;
  line-height: 30px; /* add this */
  /* here you may also add some bottom margin/padding */
}

 

Step 2:
 

.footer .footer-contact-list li span {
  height: 30px;
  width: 30px;
  border-radius: 50%;
  background: #a32020;
  display: inline-block;
  margin: 0 5px 0 0;
  position: relative;
  vertical-align: bottom; /* add this */
}
