python - Convert Base 64 String to BytesIO -


thanks can this, first question it's not super obvious.

i have image that's being passed base64 string (using slim image cropper). want convert file send google storage blob.

previously i've been sending file below 

image = request.files.get('image') client = _get_storage_client() bucket = client.bucket(current_app.config['cloud_storage_bucket']) blob = bucket.blob(filename)  blob.upload_from_string(     image.read(),     content_type=content_type)

now i'm dealing below code. 

cropped_image = json.loads(request.form.get('slim[]')) data = cropped_image['output']['image']

data variable string:

data = 'data:image/jpeg;base64,/9j/4aaqskzjrgabaqaaaqabaad/2wbd...'

i'm stuck not sure if need encode base64, decode base64, turn bytestring encode/decode??

i've tried sending using bytesio , stringio

image = bytesio(data) blob.upload_from_string(     image.read(),     content_type=content_type)

and black picture uploaded, try not ask questions without researching first 1 has me stumped.

thanks.

re.sub("data:image/jpeg;base64,", '', b64_str).decode("base64") works in python2. in py 2, str bytes actually.

update

from base64 import b64decode  open("test.jpeg", 'wb') f:     f.write(b64decode(re.sub("data:image/jpeg;base64,", '', b64_str)))  # or  image = bytesio(b64decode(re.sub("data:image/jpeg;base64", '', b64_str)))

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
