javascript - 使用 $.ajax JSON 输入字符串错误

Question

我的 Web API 接受以下 JSON 格式(这是输入参数)

[{
"atrSpaUserId": "47fe8af8-0435-401e-9ac2-1586c8d169fe",
"atrSpaClassLegendId": "00D18EECC47E7DF44200011302",
"atrSpaCityDistrictId": "144d0d78-c8eb-48a7-9afb-fceddd55622c"},
{
"atrSpaUserId": "47fe8af8-0435-401e-9ac2-1586c8d169fe",
"atrSpaClassLegendId": "00D18EECC47E7DF44200011302",
"atrSpaCityDistrictId": "144d0d78-c8eb-48a7-9afb-fceddd55622c"
}
]

我正在下面的 JavaScript 中构建请求。

var administratorId = '47fe8af8-0435-401e-9ac2-1586c8d169fe'
var districtId = '144d0d78-c8eb-48a7-9afb-fceddd55622c'

var atrUserLegendsInputs

for (i = 0; i < list.get_items().get_count() ; i++) 
{
atrUserLegendsInputs += { atrSpaUserId: administratorId, atrSpaClassLegendId:     list.getItem(i).get_value(), atrSpaCityDistrictId: districtId }  + ',';
}

atrUserLegendsInputs = atrUserLegendsInputs.substring(0,      atrUserLegendsInputs.length - 1);

var legendIds = '[' + atrUserLegendsInputs + ']';

var atrDistrictLegend = { districtID: cityDistrictId, legendIDs: legendIds };
var test = JSON.stringify(atrDistrictLegend);

获取错误消息:

{["The input was not valid."]}

我不确定我的做法是否正确。我是 Json 和 ajax 调用的新手。您能帮我解决这个问题

试试这个代码

var administratorId = '47fe8af8-0435-401e-9ac2-1586c8d169fe';
var districtId = '144d0d78-c8eb-48a7-9afb-fceddd55622c';

//* create empty array  for legends
var atrUserLegendsInputs = [];

for (i = 0; i < list.get_items().get_count() ; i++) {
    //* put some values into legends' array
    atrUserLegendsInputs.push({ 
        atrSpaUserId: administratorId,
        atrSpaClassLegendId:     list.getItem(i).get_value(),
        atrSpaCityDistrictId: districtId
    });
}

var atrDistrictLegend = {
    districtID: cityDistrictId,
    legendIDs: atrUserLegendsInputs
};
var test = JSON.stringify(atrDistrictLegend);
