urllib3

问题 Good Evening, I cannot get my https request to go through. I'm having to use SSLv3, so I'm specifying the protocol with: import requests from requests.adapters import HTTPAdapter from urllib3.poolmanager import PoolManager import ssl class MyAdapter(HTTPAdapter): def init_poolmanager(self, connections, maxsize, block=False): self.poolmanager = PoolManager(num_pools=connections, maxsize=maxsize, block=block, ssl_version=ssl.PROTOCOL_SSLv3) username = 'username' password = 'password' email =

问题 I am trying to connect to snowflake from python. It's very simple straight forward, but unfortunately I'm unable to succeed. Same piece of code works in other machines (when my friends tested). Not sure what dependencies I'm missing. Tried debugging very hard, even tried with pipenv (assuming python path must be conflict) but no luck. I kindly request you to help and resolve this issue. Summarising below steps what i have done. sudo -H pip install pipenv #installed pipenv mkdir -p test_vn

问题 Trying to use urllib3 to post JSON-encoded data. Just want my POST payload to be raw JSON string, with content type application/json. I just cannot see how to do this. The urllib3 documentation describes posting data in "fields", i.e. dicts with (key,value) pairs, like how HTML forms are URL-encoded with the URL. But I don't want to do that. The closest I've been able to get is this (I just guessed where to put the data, as it's not documented anywhere that I can find): http = urllib3

问题 I am a new developer and learning to code in Python 3.4.2. I am running Debian linux on a Raspberry Pi3. After the fresh install I did both sudo apt-get update and sudo apt-get upgrade to get everything up to date. I am trying to test a section of code which uploads a file to Dropbox: import dropbox import urllib3 authkey = (my dropbox dev auth key) with open('test.csv','rb') as f: dbx = dropbox.Dropbox(authkey) dbx.files_upload(f.read(), '/test.csv') Now, I have no idea if the actual Dropbox

问题 I've been trying to make a request to an API, I have to pass the following body: { "description":"Tenaris", "ticker":"TS.BA", "industry":"Metalúrgica", "currency":"ARS" } Altough the code seems to be right and it finished with "Process finished with exit code 0", it's not working well. I have no idea of what I'm missing but this is my code: http = urllib3.PoolManager() http.urlopen('POST', 'http://localhost:8080/assets', headers={'Content-Type':'application/json'}, data={ "description":

问题 I've implemented a retry mechanism to requests session using urllib3.util.retry as suggested both here and here. Now, I am trying to figure out what is the best way to add a callback function that will be called on every retry attempt. To explain myself even more, if either the Retry object or the requests get method had a way to add a callback function, it would have been great. Maybe something like: import requests from requests.packages.urllib3.util.retry import Retry from requests

问题 Trying to install pip on a new python installation. I am stuck with proxy errors. Looks like a bug in get-pip or urllib3 ?? Question is do I have to go through the pain of setting up CNTLM as described here or is there a shortcut? get-pip.py documentation says use --proxy="[user:passwd@]proxy.server:port" option to specify proxy and relevant authentication. But seems like pip passes on the whole thing as it is to urllib3 which interprets "myusr" as the url scheme, because of the ':' I guess (

问题 I'm uploading hundreds of millions of items to my database via a REST API from a cloud server on Heroku to a database in AWS EC2. I'm using Python and I am constantly seeing the following INFO log message in the logs. [requests.packages.urllib3.connectionpool] [INFO] Resetting dropped connection: <hostname> This "resetting of the dropped connection" seems to take many seconds (sometimes 30+ sec) before my code continues to execute again. Firstly what exactly is happening here and why?

问题 This is based on another question on this site: What's the best way to download file using urllib3 However, I cannot comment there so I ask another question: How to download a (larger) file with urllib3? I tried to use the same code that works with urllib2 (Download file from web in Python 3), but it fails with urllib3: http = urllib3.PoolManager() with http.request('GET', url) as r, open(path, 'wb') as out_file: #shutil.copyfileobj(r.data, out_file) # this writes a zero file shutil
