【问题描述】：

我有一个这样的 api 定义：

{
"myVar01": "{{myVar01}}",
"myVar02": "{{myVar02}}",
"myVar03": "{{<myVar03>}}",
"myVar04": {
    "myVar04-01": "{{myVar04-01}}",
    "myVar04-02": "{{myVar04-02}}",
    "myDataArray": [
        {
            "myArrayVar01": "{{myArrayVar01}}",
            "myArrayVar02": "{{myArrayVar02}}",
            "myArrayVar03": "{{myArrayVar03}}",
            "myArrayVar04": "{{myArrayVar04}}",
            "myArrayVar05": "{{myArrayVar05}}"
        },
        {
            "myArrayVar01": "{{myArrayVar01}}",
            "myArrayVar02": "{{myArrayVar02}}",
            "myArrayVar03": "{{myArrayVar03}}",
            "myArrayVar04": "{{myArrayVar04}}",
            "myArrayVar05": "{{myArrayVar05}}"
        },
        .....
    ]
    ]
}

}

我必须创建一个数据文件来在这个 api 上运行几个测试，问题是我如何定义我的数据文件来为“myDataArray”结构创建数据？

【问题讨论】：

使用变量名称和值创建 csv 文件。参考这个答案：stackoverflow.com/a/55058791/4753489
谢谢，但这不是我问的问题，我已经有了 CSV 文件，实际上不是 CSV，我使用 JSON 文件，因为我无法从 CSV 文件中获取变量并且它可以正常工作就像 JSON 的魅力一样，但没关系。问题是关于在文件中创建一个 kindof 数组来为每个测试组处理 myDataArray 的多个值

【解决方案1】：

好的，终于找到问题了。

API 定义必须是这样的：

    {
    "myVar01": "{{myVar01}}",
    "myVar02": "{{myVar02}}",
    "myVar03": "{{myVar03}}",
    "Struct": {
        "myVar04-01": "{{myVar04-01}}",
        "myVar04-02": "{{myVar04-02}}",
        "myDataArray": {{localVarDataAray}}
    }
}

json 文件必须是这样的：

    [
{
  "myVar01": "0123456789012345678901234567890123456789",
  "myVar02": "0123456789012345678901234567890123456789",
  "myVar03": "0123456789012345678901234567890123456789",
  "myVar04-01": "0123456789012345678901234567890123456789",
  "myVar04-02": "0123456789012345678901234567890123456789",
  "myDataArray":[{
                "myArrayVar01": 1,
                "myArrayVar02": 1,
                "myArrayVar03": 1,
                "myArrayVar04": 4,
                "myArrayVar05": 0
            },{
                "myArrayVar01": 2,
                "myArrayVar02": 2,
                "myArrayVar03": 2,
                "myArrayVar04": 4,
                "myArrayVar05": 0
            }]
},
{
  "myVar01": "0123456789012345678901234567890123456789",
  "myVar02": "0123456789012345678901234567890123456789",
  "myVar03": "0123456789012345678901234567890123456789",
  "myVar04-01": "0123456789012345678901234567890123456789",
  "myVar04-02": "0123456789012345678901234567890123456789",
  "myDataArray":[{
                "myArrayVar01": 1,
                "myArrayVar02": 1,
                "myArrayVar03": 1,
                "myArrayVar04": 4,
                "myArrayVar05": 0
            },{
                "myArrayVar01": 2,
                "myArrayVar02": 2,
                "myArrayVar03": 2,
                "myArrayVar04": 4,
                "myArrayVar05": 0
            }]
}
]

我必须像这样定义一个预请求脚本：

 let localVarDataAray="";
pm.variables.set('localVarDataAray',JSON.stringify(data.myDataArray));

而且效果很好
