Question

您能否建议如何在Robot Framework中使用JsonPath？它应该支持多级查询，如下所示：

CSS

我正在寻找下列工作的方法：

$.items[?(@.status.name="closed")].name

像这样

此RF代码可满足您的需求，但仅适用于提供的json结构。从我的角度来看，你应该玩Get Json Value并准备你需要的关键词。顺便说一下，很明显RF中的这种json /字符串处理有点复杂，所以我宁愿用你需要的关键字编写小的Python库。

*** Settings ***
Library            Collections
Library            HttpLibrary.HTTP

*** Variables ***
${json}         {"items":[{"name":"item1","status":{"id":1,"name":"opened"}},{"name":"item2","status":{"id":2,"name":"closed"}}]}
${name}    ${EMPTY}
${result}    ${EMPTY}

*** Test Cases ***
Get Closed Item
    ${name}    Get Name By Status    ${json}    closed
    Should Be Equal As Strings    ${name}    item2
    ${name}    Get Name By Status    ${json}    opened
    Should Be Equal As Strings    ${name}    item1

*** Keywords ***
Get Name By Status
    [Arguments]    ${json}    ${status}
    [Return]    ${result}
    ${json}    Parse Json    ${json}
    :FOR    ${item}    IN    @{json["items"]}
    \    ${item}    Stringify Json    ${item}
    \    ${name}    Get Json Value    ${item}    /name
    \    ${name}    Parse Json    ${name}
    \    ${status_name}    Get Json Value    ${item}    /status/name
    \    ${status_name}    Parse Json    ${status_name}
    \    ${result}    Set Variable If    '${status_name}' == '${status}'    ${name}    ${result}

编辑：根据下面的评论，我会选择基于python的代码。

JsonpathLibrary.py：

#!/usr/bin/python
# -*- coding: utf-8 -*-
import json
import jsonpath

class JsonpathLibrary(object):

    def get_items_by_path(self, json_string, json_path):
        json_object = json.loads(json_string)
        match_object = jsonpath.jsonpath(json_object, json_path)
        match_string = json.dumps(match_object[0])
        return match_string

RF代码：

*** Settings ***
Library            JsonpathLibrary.py

*** Variables ***
${json}         {"items":[{"name":"item1","status":{"id":1,"name":"opened"}},{"name":"item2","status":{"id":2,"name":"closed"}}]}
${json_path}    $.items[?(@.status.name=="closed")].name

*** Test Cases ***
Some Descriptive Name Here
    ${name}    Get Items By Path    ${json}    ${json_path}
    Should Be Equal As Strings    ${name}    "item2"

如何在RobotFramework中使用功能齐全的JsonPath？
