python接口自动化--获取sign和token的方法，class半封装

获取sign的方法

需求：para参数，按照key的首字母大小排序，并前后拼接secret_key，md5转换后，输出sign

def get_sign():
        para={"from": "ios_pad", "account_id": account_id, 'signed_at': get_signed_at(), "phone": '*************',
         "code": code, "nickname": "guozhendeng1"}

        t = sorted(self.para.items(), key=lambda item: item[0])  
        # 进行字典排序sorted根据首字母先后排序
        
        re = ''
        for x in t:
            re += "".join(["".join(x)])

        signss = secret_key + re + secret_key

        #循环排列
        m1 = hashlib.md5()  # md5转换
        m1.update(signss.encode(encoding='utf-8'))
        sign = m1.hexdigest()
        return sign
