robot framework 接口返回值的处理

接口返回值为：

{"data":{"data":[[{"key1":"value1"},{"key2":"value2"},{"key3":"value3"}],[{"key11":"value11"},{"key12":"value12"},{"key13":"value13"}]]},"result":"1"}

#格式化

{
    "data": {
        "data": [
            [
                {
                    "key1": "value1"
                }, 
                {
                    "key2": "value2"
                }, 
                {
                    "key3": "value3"
                }
            ], 
            [
                {
                    "key11": "value11"
                }, 
                {
                    "key12": "value12"
                }, 
                {
                    "key13": "value13"
                }
            ]
        ]
    }, 
    "result": "1"
}

想取  value13，可以这样写

    Comment    ${res_utf8}    decodeutf8    ${res_agree}    #转码，如果不需要可注释
    ${res}    Set Variable    {"data":{"data":[[{"key1":"value1"},{"key2":"value2"},{"key3":"value3"}],[{"key11":"value11"},{"key12":"value12"},{"key13":"value13"}]]},"result":"1"}
    ${res_json}    to json    ${res}    #先将返回值转成json，如果不需要可注释
    ${res_data}    Get From Dictionary    ${res_json}    data    #取第一层data
    ${res_data2}    Get From Dictionary    ${res_data}    data    #取第二层data
    ${res_list}    Get From List    ${res_data2}    1    #取list中第二个
    ${res_list2}    Get From List    ${res_list}    2    #取list中第三个
    ${res_key12}    Get From Dictionary    ${res_list2}    key13    #取value13

结果如下：
