使用python中另一个类中的类和类方法

Question

我有几节课吉拉.py，提供2个样品

class JiraCommand:

    name = "<default>"
    aliases = []
    summary = "<--- no summary --->"
    usage = ""
    mandatory = ""

    commands = None

    def __init__(self, commands):
        self.commands = commands

    def dispatch(self, logger, jira_env, args):
        """Return the exit code of the whole process"""
        if len(args) > 0 and args[0] in ("--help", "-h"):
            logger.info("")
            alias_text = ''
            first_alias = True
            for a in self.aliases:
                if first_alias:
                    if len(self.aliases) == 1:                
                        alias_text = " (alias: " + a          
                    else:                                     
                        alias_text = " (aliases: " + a        
                    first_alias = False                       
                else:                                         
                    alias_text +=  ", " + a                   
            if not first_alias:                               
                alias_text += ")"                             
            logger.info("%s: %s%s" % (self.name, self.summary, alias_text))  
            if self.usage == "":                              
                opts = ""                                     
            else:                                             
                opts = " [options]"                           
            logger.info("")                                   
            logger.info("Usage: %s %s %s%s" % \               
                  (sys.argv[0], self.name, self.mandatory, opts))
            logger.info(self.usage)                           
            return 0                                          
        results = self.run(logger, jira_env, args)            
        if results:                                           
            return self.render(logger, jira_env, args, results)
        else:                                                 
            return 1                                          

    def run(self, logger, jira_env, args):                    
        """Return a non-zero object for success"""            
        return 0                                              

    def render(self, logger, jira_env, args, results):        
        """Return 0 for success"""                            
        return 0 

在同一个文件中还有第二个类”吉拉.py““

^{pr2}$

现在，JiraCat使用JiraCommand作为参数

如何使用JiraCat获取实时结果

以下是我尝试的：

>>> from jira import JiraCommand
>>> dir(JiraCommand)
['__doc__', '__init__', '__module__', 'aliases', 'commands', 'dispatch', 'mandatory', 'name', 'render', 'run', 'summary', 'usage']

>>> jcmd = JiraCommand("http://jira.server.com:8080")

>>> from jira import JiraCat
>>> dir(JiraCat)
['__doc__', '__init__', '__module__', 'aliases', 'commands', 'dispatch', 'mandatory', 'name', 'render', 'run', 'summary', 'usage']
>>> jc = JiraCat(jcmd)
>>> print jc
<jira.JiraCat instance at 0x2356d88>

>>> jc.run("-s", "cat", "QA-65")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "jira.py", line 163, in run
    logger.error(self.usage)
AttributeError: 'str' object has no attribute 'error'

Answer 1

唐卡利斯托说得对。在

JiraCat的run方法接受三个参数（logger、jira_env、args）；第一个参数应该是logger对象，但传递的是字符串（“-s”）。在

因此，报告字符串的错误（logger=“-s”）没有“error”属性，仅此而已。在

你对命令行的评论(子流程.Popen（['python'，'jira'，'-s'，'jira.server.com:8080'；，'catall'，'JIRA-65']））与使用相同参数调用run（）方法不同。看看底部吉拉.py看看它能做什么系统argv... 在

编辑（1）： 在阅读了代码之后，下面的python应该复制您的命令行调用。它有点复杂，并且忽略了吉拉.py我不能在这里测试。在

import jira
import os

com = jira.Commands()
logger = jira.setupLogging()
jira_env = {'home':os.environ['HOME']}
command_name = "cat"
my_args = ["JIRA-65"]
server = "http://jira.server.com:8080" + "/rpc/soap/jirasoapservice-v2?wsdl"

class Options:
    pass

options = Options()
#You might want to set options.user and options.password here...

jira.soap = jira.Client(server)
jira.start_login(options, jira_env, command_name, com, logger)
com.run(command_name, logger, jira_env, my_args)
