追加的方法一类

Question

你好，我有一个RobotFramework库请求 /usr/local/lib/python2.7/dist-packages/RequestsLibrary/RequestsKeywords.py

是缺少一些代码来暴露摘要认证方法在Python.Requests库中。我想要做的不是将其入侵到 /usr/local/lib/python2.7/dist-packages/RequestsLibrary/RequestsKeywords.py

我想添加如果到我的代码目录和只是将其追加到入口即化

类的类= RequestsKeywords

在C＃等我会用一个局部类，但似乎并没有被这种事情在Python任何想法如何PROCEDE

这里是我想要“APPEND”进入 的代码/usr/local/lib/python2.7/dist-包/ RequestsLibrary/RequestsKeywords.py 库

def create_digest_session(self, alias, url, auth, headers={}, cookies=None, timeout=None, proxies=None, verify=False): 

    """ Create Session: create a HTTP session to a server 

    `url` Base url of the server 

    `alias` Robot Framework alias to identify the session 

    `headers` Dictionary of default headers 

    `auth` List of username & password for HTTP Digest Auth 

    `timeout` connection timeout 

    `proxies` proxy server url 

    `verify` set to True if Requests should verify the certificate 
    """ 
    digest_auth = requests.auth.HTTPDigestAuth(*auth) if auth else None 
    return self._create_session(alias, url, headers, cookie, digest_auth, timeout, proxies, verify) 

任何建议

所以我的测试是这样的下面，你与sys.path.append指定的Python代码将文件RequestsKeywordsLocal英寸py 是否正确？

*** Settings *** 
Suite Teardown Delete All Sessions 
Library   Collections

*** Test Cases *** 
Check IP valid 
    Valid Ip ${IP} 

Get Valid Hostname 
    ${host}= Valid Hostname ${IP} 
    Should Not Be Equal As Strings ${host} "noname" 

Get With DigestAuth 
    [Tags] get 
    Log Variables 
    ${auth}= Create List username password 
    Create Digest Session TerraceQ https://${IP} auth=${auth} 
    ${resp}= Get TerraceQ /views 
    Should Be Equal As Strings ${resp.status_code} 200 
    Should Contain ${resp.content} views 

Answer 1

您可以子类：

class MyNewXThing(XThing): 
    def my_added_method(self, x, y, z): 
     # ... 

而且使用MyNewXThing而不是XThing整个代码。或者：

def my_added_method(self, x, y, z): 
    # ... 
XThing.my_added_method = my_added_method 

第一个选项是比较灵活的，因为它不会为任何其他代码更改XThing。

你可以导入类，内在并添加所需的功能

sys.path.append('/usr/local/lib/python2.7/dist-packages/RequestsLibrary/') 
import RequestsKeywords as RequestsKeywords 


class RequestsKeywords_local(RequestsKeywords): 

    def create_digest_session(self, alias, url, auth, headers={}, cookies=None, timeout=None, proxies=None, verify=False): 

     """ Create Session: create a HTTP session to a server 

     `url` Base url of the server 

     `alias` Robot Framework alias to identify the session 

     `headers` Dictionary of default headers 

     `auth` List of username & password for HTTP Digest Auth 

     `timeout` connection timeout 

     `proxies` proxy server url 

     `verify` set to True if Requests should verify the certificate 
     """ 
     digest_auth = requests.auth.HTTPDigestAuth(*auth) if auth else None 
     return self._create_session(alias, url, headers, cookie, digest_auth, timeout, proxies, verify) 

    def __init__(self,**kwargs): 

     RequestsKeywords.__init__(self,**kwargs)
