amazon web services - Signing S3 urls fails (The request signature we calculated does not match the signature you provided. Check your key and signing method) -


i'm trying generate signed urls upload , download objects in s3 bucket, fails "signaturedoesnotmatch" per below.

<?xml version="1.0" encoding="utf-8"?> <error><code>signaturedoesnotmatch</code><message>the request signature calculated not match signature provided. check key , signing method.</message><awsaccesskeyid>akiaj66rwejpywx6pl2a</awsaccesskeyid><stringtosign>get

i understand symptom problem described here

amazon mws - request signature calculated not match signature provided

that is, credentials somehow wrong. double checked .aws/credentials file , generated new ones. moreover, can other aws operations these credentials, such querying dynamodb or listing buckets.

the code use generate urls, copied here:

http://docs.aws.amazon.com/amazons3/latest/dev/shareobjectpresignedurljavasdk.html

final zoneddatetime expiration = zoneddatetime.now().plusseconds(expirationseconds);  final generatepresignedurlrequest generatepresignedurlrequest = new generatepresignedurlrequest(     bucketname, objectid.tostring()); generatepresignedurlrequest.setmethod(isupload ? httpmethod.put : httpmethod.get); generatepresignedurlrequest.setexpiration(date.from(expiration.toinstant()));  return amazons3client.generatepresignedurl(generatepresignedurlrequest).touri();

and, yes, bucket exists. how can bottom this?

i found problem, using chrome plugin "advanced rest client" send request , guess cors rule make request fail apps' javascript. doing request address filed of browser works.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
