Writing adorners to implement Python request error retry function

In the interface Automation test, always encountered, due to the connection timeout and other errors caused by the interface script failed.

The Official method:

Max_retries=5 Error retry 5 times
Note that this only retries for DNS, connection errors.

     from Import Httpadapter     = requests. Session ()    s.mount ('http//', Httpadapter (max_retries=5))    S.mount (  'https://', Httpadapter (max_retries=5))    s.get ('  https://www.baidu.com')

Self-authoring Decorator One

Self-Authoring Decorator II

 fromRequests.exceptionsImportConnectionerrordefRetry (* *kw):defWrapper (func):def_wrapper (*args,**Kwargs): raise_ex=None for_inchRange (kw['Renum']):                Print _                Try:                    returnFunc (*args,**Kwargs)exceptConnectionerror as EX:RAISE_EX=ex#Raise RAISE_EX        return_wrapperreturnWrapper

How to use: Renum = 5 means that connectionerror can be retried up to 5 times.

@retry (renum=5)def  demo ():    raise connectionerror

Summarize:

1. Writing adorners is actually not that difficult, just master the method. This is a reference to the article I wrote about adorners.

2. The pre-cooked explanation of the adorner is to do something after the function. Through this we can do a lot.

3. About the request connection error, retry, adorner; the principle is to do a loop, as long as the capture of a connectionerror error, enter the next cycle

Called, and returns the function directly whenever there is a right time.
