替换数据里参数的方法

def replace_value(self, data):
    if data:
        # 保存数据类型
        data_type = type(data)
        # 判断数据类型转换成str
        if isinstance(data, dict) or isinstance(data, list):
            #将python数据结构转换为json
            str_data = json.dumps(data)
        else:
            str_data = str(data)
        for cs in range(1, str_data.count('${') + 1):
            # 替换
            #判断 { } 括号是否包含在数据中
            if "${" in str_data and "}" in str_data:
                #获取{ 的索引
                start_index = str_data.index("${")
                #获取} 的索引
                end_index = str_data.index("}", start_index)
                #数据截取
                old_value = str_data[start_index:end_index + 1]
                #
                new_value = read_yaml(old_value[2:-1])
                #新数据替换旧的数据
                str_data = str_data.replace(old_value, new_value)
        # 还原数据类型
        if isinstance(data, dict) or isinstance(data, list):
            #json字符串解码为python对象
            data = json.loads(str_data)
        else:
            #强制转为开始定义时的数据类型
            data = data_type(str_data)
    return data

封装发送请求的方法

sess = requests.session()
    # 统一请求封装
    def send_request(self, method, url, **kwargs):
        method = str(method).lower()  # 转换小写
        # 基础路径的拼接和替换
        url = self.base_url + self.replace_value(url)
        print(url)
        # 参数替换
        for key, value in kwargs.items():
            if key in ['params', 'data', 'json', 'headers']:
                kwargs[key] = self.replace_value(value)
            elif key == "files":
                for file_key, file_path in value.items():
                    value[file_key] = open(file_path, 'rb')
        res = RequestUtil.sess.request(method, url, **kwargs)
        print(res.text)
        return res
