新手看了一段代码，百思不得姐

Question

class MyUnittestTestCase(unittest.TestCase):
def init(self, methodName='runTest', http=None, casestep=None):
super(MyUnittestTestCase, self).__init__(methodName)
self.http = http
self.url = casestep.get_action()['url']
self.params = casestep.get_action()['params']
self.testcase_id = casestep.get_tasecase_id()
self.step_id = casestep.get_step_id()
self.expected_result = casestep.get_expected_result()
请问这两句是什么意思，尤其不知道后面的['url']和['params']是什么意思
self.url = casestep.get_action()['url']
self.params = casestep.get_action()['params']

    新手没有分，不好意思

Answer 1

get_action()返回一个字典类型，get_action()['params']得到返回字典的key为params对应的值。
url是地址，params是参数
