first of all sorry for my English, it's not my mother tongue. I'm writing a XML parser in python 2.7. There are a links for images, that are downloading and saving into DB, it works fine with http, but I need to download them from ftp server.
Here is function that is calling from parser:
q=sa_web_images.objects.create(
web_image_url=iphoto,
web_item_id=wi_id,
non_repeat=non_repeat
)
q.get_remote_image()
Where 'iphoto' is a link, for example: ftp://example.com/image.jpg.
And here is function that save it into DB:
def get_remote_image(self):
if self.web_image_url and not self.web_image:
result = urllib.urlretrieve(self.web_image_url)
self.web_image.save(
os.path.basename(self.web_image_url),
File(open(result[0]))
)
self.save()
I know username and password for ftp access, but I don't know, how should I insert them into code, can someone help me please? Thanks.
username and password can be supplied to urllib by specifying them in the url, like for example
result = urllib.urlretrieve("ftp://user:password#example.com/image.jpg")

I am stuck with this problem that I have had for a while.
I have code here that is intended to upload a file to a web server.
class uploadFile_Functions():
def __init__(self, DESTINATION_URL, TARGET_FILE):
self.DESTINATION_URL = DESTINATION_URL
self.TARGET_FILE = TARGET_FILE
def uploadFile_WebServ(self):
dest_site = self.DESTINATION_URL
t_file = self.TARGET_FILE
with open(t_file,'rb') as f:
print('Uploading the file to the server')
upload_req = requests.post(dest_site, files={t_file:f})
print('Upload successful')
The dest_site will contain the link to the webpage folder that I have, and the t_file will contain the file to be uploaded.
What happens is that when I run this code, there were no errors thrown during runtime, and the shell printed the 'Upload successful' statement. But I checked the webpage folder in chrome, and the file is not even there.
I do not know if this needs some sort of authentication since this is a web server. I was able to get a file from the same webpage folder using the GET method, but no success so far with the POST method.
I appreciate any answer that I get from you guys. Thank you!
I'm very very new to python. I have a HTML code with POST method to upload a file, then I have python code to receive the file and save it to a FTP server. My python code so far is :
berkas = request.FILES['file']
filename = "test_send_file.jpg"
upload_folder = '/var/www/uploads/target_folder/'
handle_uploaded_file(join(upload_folder, filename), berkas)
Using those codes I got Permission Denied when uploading the file.
I know the missing part is where I have to set FTP server address and it's username & password, but I don't know how to that.
So, how to do it ?
Or, is there easier way to solve my "POST upload then save to FTP" problem ?
Thank you before.
All the examples I can find on google endpoint api (e.g., tic-tac-toe sample) show strings, integers, enums, etc fields. None of the examples say anything about how to specify document (e.g., image or zip files) uploads or downloads using the API. Is this not possible?
If this is possible, can anyone share a code snippet on how to define google endpoint api on the server to allow downloads and uploads of files? For example, is there a way to set HTTPResponse headers to specify that an endpoint response will serve a zip file? How do we include the zip file in the response?
An example with python or php would be appreciated. If anyone from the endpoints-proto-datastore team is watching this discussion, please say whether or not file downloads are supported in endpoints at the moment. We hate to waste our time trying to figure this out if it is simply impossible. Thanks.
We are seeking a complete example for upload and download. We need to store the key for the uploaded file in our database during upload and retrieve it for download. The client app sends a token that the API needs to use to figure out what file to download. Hence, we would need to store the blob key generated during the upload process in our database. Our database would have the mapping between the token and the blob file's key.
class BlobDataFile(models.Model):
data_code = models.CharField(max_length=10) # Key used by client app to request file
blob_key = models.CharField()
By the way, our app is written in Django 1.7 with a mysql (modeled with models.Model) database. It is infuriating that all the examples for Google App Engine upload I can find is written for a standalone webapp Handlers (no urls.py/views.py solutions could be found anywhere). Hence, building a standalone uploader is as much of a challenge as writing the API code. If your solution has full urls.py/views.py example for uploading files and saving the blob_key in our BlobDataFile, it would be good enough for us.
f you use the blobstore use the get_serving_url function to read the images from url in the client, or use the messages.ByteField in the ResourceContainer and serialize the image with base64.b64decode
#the returned class
class Img(messages.Message):
message = messages.BytesField (1)
#The api class
#endpoints.api(name='helloImg', version='v1')
class HelloImgApi(remote.Service):
ID_RESOURCE = endpoints.ResourceContainer(
message_types.VoidMessage,
id=messages.StringField(1, variant=messages.Variant.STRING))
#endpoints.method(ID_RESOURCE, Img,
path='serveimage/{id}', http_method='GET', #ID is the blobstore key
name='greetings.getImage')
def image_get(self, request):
try:
blob_reader = blobstore.BlobReader(blob_key)
value = blob_reader.read()
return Img(message=value)
except:
raise endpoints.NotFoundException('image %s not found.' %
(request.id,))
APPLICATION = endpoints.api_server([HelloImgApi])
And this is the response (save it in the client with the proper format)

}
in the client you can do this (in python for continuity)
import base64
myFile = open("mock.jpg", "wb")
img = base64.b64decode(value) #value is the returned string
myFile.write(img)
myFile.close()
Did you try converting the image to base64 string and send it as an argument of your request on the client side?
So you will be able to do that on the server side :
#strArg is the Base64 string sent from the client
img = base64.b64decode(strArg)
filename = 'someFileName.jpg'
with open(filename, 'wb') as f:
f.write(img)
#then you can save the file to your BlobStore
I'm trying to save files sent from C++ code(not by HTML)
But I do not know how to write the script to parse sent data and save it
C++ code works fine(from wireshark captured packet)
from Bottle tutorial: how do I edit it?
category = request.forms.get('category')
upload = request.files.get('upload')
thanks!
update:
I found that request.files works
files = request.files
for name, fobj in files.iteritems():
fobj.save(some_path)
If you are just sending the raw file in the HTTP request, access it with request.body.
http://bottlepy.org/docs/dev/api.html#bottle.BaseRequest.body
This is what I ended up doing:
from bottle import FileUpload
uploaded_file = FileUpload(request.body, None, filename='some_filename')
uploaded_file.save() # implement conflict resolution here, if needed
I am working in Django.I am trying to connect my website to Facebook. What i want to do is
1)Send post_data
post_data = [('access_token',access_token), ('message', message), ('link', some_link),('picture',internal_server_path_of_image)
2)urllib2.urlopen(graph_url, urllib.urlencode(post_data))
What this should do is post that data on the facebook profile of a user. But i am unable to access "internal_server_path_of_image". Is there anyway in which i can make a particular folder on my server available to the site ? i.e. the images on that folder should be accessible from outside.
for e.g. I have folder site_name/project/images/photos.png
on the server some_server.dreamhost.com/site_name/project/images/photos.png. Now i want to access this image somehow.
Is the question clear ? or do I need to add a few things ?
Any help will be highly appreciated.
I have come with a solution. As people had pointed out that the imagefield gives us the url of the image. That was true, what i am doing now is passing that url. At that url i have written a controller method. This method simply renders the image and returns it. This gives access to the facebook api to get the required image from my server.
def test(request,name):
name = str(name)+".jpg"
url = "Users/admin/workspace/bolt/templates/media/images/photos/"
full = url+name image_data = open(full, "rb").read()
return HttpResponse(image_data, mimetype="image/png")
Hope this helps others
