Question

我正在尝试构建一个可以驱动我的Web应用程序的JSON对象，但是我当前正在返回一个无效的JSON对象，我看不到问题，

我通过JSON Lint运行了JSON，我收到以下错误，

第19行的解析错误：   ......]}，
  ---------------------- ^   期待'STRING'，'NUMBER'，'NULL'，'TRUE'，'FALSE'，'{'，'['

我的JSON对象在下面，

    {
    "name": "FF",
    "good": {

        "doors" : [
            {
                "name" : "Door Name 1",
                "thumb": "http://placehold.it/134x134/ff0000/ffffff",
                "specifics" : [
                     "Specifics 1a",
                    "Specifics 2a"
                ]   
            },
            {
                "name" : "Door Name 2",
                "thumb": "http://placehold.it/134x134/b4da55/ffffff",
                "specifics" : [
                    "Specifics 1b",
                    "Specifics 2b",
                    "Specifics 3b",
                ]   
            }, //LINE 19 - Where the JSON Lint states there to be an error.
            {
                "name" : "Door Name 3",
                "thumb": "http://placehold.it/134x134/0000ff/ffffff",
                "specifics" : [
                     "Specifics 1c",
                    "Specifics 2c",
                    "Specifics 3c",
                    "Specifics 4c"
                ]   
            },
        ],
        "walls" : [
            {
                "name" : "Chair Rail A",
                "thumb": "http://placehold.it/134x134/0000ff/ffffff",
                "specifics" : [
                    "Chair Rail A",
                ]   
            },
            {
                "name" : "Wall Paneling with Rosettes A",
                "thumb": "http://placehold.it/134x134/b4da55/ffffff",
                "specifics" : [
                    "Panel Moulding A",
                    "4\" Rossette"
                ]   
            },
            {
                "name" : "Wall Paneling with Rossettes B",
                "thumb": "http://placehold.it/134x134/ff0000/ffffff",
                "specifics" : [
                    "Panel Moulding A",
                    "6\" Rossette"
                ]   
            },
        ],

    },
    "best": {},
    "better": {}
}

我认为问题来自于尝试在对象中使用数组，因此在循环时我可以有多个选项，这是正确的吗？如果是这样，我的JSON应该如何形成？

Answer 1

在JSON的许多地方，你都有悬空逗号。摆脱那些，你的JSON将解析。在这些场合，我总觉得jsonlint.com是一个有用的工具。

Answer 2

数组项后面有一个额外的逗号，就在这里：

    "specifics" : [
        "Specifics 1b",
        "Specifics 2b",
        "Specifics 3b", //there is no next element, remove the ,
    ]

同样的情况也出现在这里：

    "specifics" : [
        "Chair Rail A",
    ]

在wall属性之后还有一个额外的逗号：

"walls" : [
    {
        "name" : "Chair Rail A",
        "thumb": "http://placehold.it/134x134/0000ff/ffffff",
        "specifics" : [
            "Chair Rail A",
        ]   
    },
    {
        "name" : "Wall Paneling with Rosettes A",
        "thumb": "http://placehold.it/134x134/b4da55/ffffff",
        "specifics" : [
            "Panel Moulding A",
            "4\" Rossette"
        ]   
    },
    {
        "name" : "Wall Paneling with Rossettes B",
        "thumb": "http://placehold.it/134x134/ff0000/ffffff",
        "specifics" : [
            "Panel Moulding A",
            "6\" Rossette"
        ]   
    },
], //Remove me

这里的问题是JSON格式错误。这是正确的格式：

{
"name": "FF",
"good": {

    "doors" : [
        {
            "name" : "Door Name 1",
            "thumb": "http://placehold.it/134x134/ff0000/ffffff",
            "specifics" : [
                 "Specifics 1a",
                "Specifics 2a"
            ]   
        },
        {
            "name" : "Door Name 2",
            "thumb": "http://placehold.it/134x134/b4da55/ffffff",
            "specifics" : [
                "Specifics 1b",
                "Specifics 2b",
                "Specifics 3b"
            ]   
        },
        {
            "name" : "Door Name 3",
            "thumb": "http://placehold.it/134x134/0000ff/ffffff",
            "specifics" : [
                 "Specifics 1c",
                "Specifics 2c",
                "Specifics 3c",
                "Specifics 4c"
            ]   
        }
    ],
    "walls" : [
        {
            "name" : "Chair Rail A",
            "thumb": "http://placehold.it/134x134/0000ff/ffffff",
            "specifics" : [
                "Chair Rail A"
            ]   
        },
        {
            "name" : "Wall Paneling with Rosettes A",
            "thumb": "http://placehold.it/134x134/b4da55/ffffff",
            "specifics" : [
                "Panel Moulding A",
                "4\" Rossette"
            ]   
        },
        {
            "name" : "Wall Paneling with Rossettes B",
            "thumb": "http://placehold.it/134x134/ff0000/ffffff",
            "specifics" : [
                "Panel Moulding A",
                "6\" Rossette"
            ]   
        }
    ]

},
"best": {},
"better": {}
}

你在json中使用过多逗号。

我使用jsoneditoronline.org来验证JSON，我发现它对突出显示的错误非常有用。

你的json格式无效，你的代码中有很多,，在线验证你的json代码。
