我试图创建一个JSON文档，其中包含一个对象数组，其中每个对象都有一个特定的“名称”，因此我创建了这个JSON文档：
{
"forecast": [
"morning": {
"date": "01/10/2018",
"min_temp": "12",
"max_temp": "24",
"humidity": "2",
"wind_direction": "SO",
"wind_force": "12",
"status": "OK",
"description": "sdfsdfsdf"
},
"afternoon": {
"date": "01/10/2018",
"min_temp": "",
"max_temp": "",
"humidity": "",
"wind_direction": "",
"wind_force": "",
"status": "",
"description": ""
}
]
}
如您所见，forecast数组包含2个名为morning和午后的JSON对象。
但是通过这种方式，我获得了以下错误消息，试图在验证器（https://jsonlint.com/）上验证这个JSON文档，获得的错误是：
错误：第3行的分析错误：。。。演员阵容“：[“上午”：{“日期”：“01/1--------------------^应为'EOF'、'}'、'、']'，获得'：'
以这种格式更改以前的JSON文档（基本上删除JSON对象名称）它工作正常，并且正确验证：
{
"forecast": [
{
"date": "01/10/2018",
"min_temp": "12",
"max_temp": "24",
"humidity": "2",
"wind_direction": "SO",
"wind_force": "12",
"status": "OK",
"description": "sdfsdfsdf"
},
{
"date": "01/10/2018",
"min_temp": "",
"max_temp": "",
"humidity": "",
"wind_direction": "",
"wind_force": "",
"status": "",
"description": ""
}
]
}
为什么第一个版本没有验证？我可以将对象名称放入JSON文档中的数组中吗？或者我必须添加上午、下午的信息作为每个对象的值字段？
您缺少数组元素周围的大括号：
{
"forecast": [
{ // HERE
"morning": {
"date": "01/10/2018",
"min_temp": "12",
"max_temp": "24",
"humidity": "2",
"wind_direction": "SO",
"wind_force": "12",
"status": "OK",
"description": "sdfsdfsdf"
},
"afternoon": {
"date": "01/10/2018",
"min_temp": "",
"max_temp": "",
"humidity": "",
"wind_direction": "",
"wind_force": "",
"status": "",
"description": ""
}
} // HERE
]
}
您拥有的不是有效的JSON。数组元素不能有“名称”，因为这只是一个对象。。。
{
"forecast": {
"morning": {
"date": "01/10/2018",
"min_temp": "12",
"max_temp": "24",
"humidity": "2",
"wind_direction": "SO",
"wind_force": "12",
"status": "OK",
"description": "sdfsdfsdf"
},
"afternoon": {
"date": "01/10/2018",
"min_temp": "",
"max_temp": "",
"humidity": "",
"wind_direction": "",
"wind_force": "",
"status": "",
"description": ""
}
}
}
另一种方法是将名称放入数组中的对象中。
{
"forecast": [
{
"name": "morning",
"date": "01/10/2018",
"min_temp": "12",
"max_temp": "24",
"humidity": "2",
"wind_direction": "SO",
"wind_force": "12",
"status": "OK",
"description": "sdfsdfsdf"
},
{
"name": "afternoon",
"date": "01/10/2018",
"min_temp": "",
"max_temp": "",
"humidity": "",
"wind_direction": "",
"wind_force": "",
"status": "",
"description": ""
}
}
}
