特別注意：
api_res = self.cache_api_wrapper.get_api(self.network_api_svc.network_whole_features, company_name)
與以前的直接通過呼叫api獲取網路圖特徵不同，此處外面還加了多程序get_api函式；
直接呼叫它會報錯！

**local()用法：**
**locals() 函式會以字典型別返回當前位置的全部區域性變數。**
對於函式, 方法, lambda 函式, 類, 以及實現了 __call__ 方法的類例項, 它都返回 True
>>>def runoob(arg):    # 兩個區域性變數：arg、z
...     z = 1
...     print (locals())
... 
>>> runoob(4)
{'z': 1, 'arg': 4}      # 返回一個名字/值對的字典
>>>

 當前locals()返回的是：
 {'network_whole_features': <MagicMock name='network_whole_features' id='140258690673808'>, 'company_name': u'\u6d4b\u8bd5\u516c\u53f8', 'self': <test_networkFeaturesSingle.TestNetworkFeaturesSingle testMethod=test_get_features>}
