REST API：获取所有电脑

Question

我的 REST API 脚本有问题，在我将趋势科技服务器深度安全防护系统从 11.2.225 升级到 20.0.366 之前它一直有效。错误发生在“for computer in api_comp.search_computers(api_version, search_filter=search_filter).computers:”这一行执行脚本时出现的错误如下所示：

需要的脚本部分：

                        if rule.id not in rulesToAdd:

                        f.write(policy.name + ";" + computer.host_name + ";" + str(rule.id) + ": " + rule.name + "\n")
        except Exception as e:
            logging.exception("Exception on Computer ", computer.id)

有没有人知道失败的原因、发生了什么变化以及我能做什么？

Answer 1

日志告诉我们问题发生在策略循环中。错误消息（“无效的 SearchFilter：字段 policyID 不支持 choiceTest”）告诉我们问题是 SearchFilter 在尝试搜索 policyID 字段时包含 choiceTest。

查看代码，我看到 search_criteria 变量被重新使用。这意味着第三次使用它时，它将沿用第二次使用时的 choiceTest 值。

尝试这样的操作（创建新的搜索条件）：

# Get all computers in that policy    
search_criteria_policy = deepsecurity.SearchCriteria()
search_criteria_policy.field_name = "policyID"
search_criteria_policy.numeric_value = policy.id
