Python - 创建 JSON 数组？并传递给ajax

Question

在我的 python 服务器端脚本中，我有以下内容

....


data = {}
data['id'] = id
data['organizer'] = organizer
data['eventStart'] = eventStartLocal
data['eventEnd'] = eventEndLocal
data['subject'] = subject
data['attendees'] = attendees
# Serializing Data 
json_data = json.dumps(data)
id += 1
print(json_data) #this is what the script returns 

在我的前端使用 jquery/javascript 我有这个..

$.ajax({
       type: 'REQUEST',
       dataType: 'text',
          url: 'json.py',
          success: function(data){
               console.log(data);
               obj = JSON.parse(data);
               },

            }).done(function(){

                console.log(obj)
            })

        });

我的输出是：

{"id": 0, "organizer": "Some Name", "eventStart": "09:30 AM", "eventEnd": "10:00 AM", "subject": "rental procedure", "attendees": "Some Name<br />Person 2<br />Person 3"}
{"id": 1, "organizer": "Some Name", "eventStart": "09:30 AM", "eventEnd": "10:00 AM", "subject": "rental procedure", "attendees": "Some Name<br />Person 2<br />Person 3"}
{"id": 2, "organizer": "Some Name", "eventStart": "09:30 AM", "eventEnd": "10:00 AM", "subject": "rental procedure", "attendees": "Some Name<br />Person 2<br />Person 3"}

我的问题

当我尝试在 javascript 中解析 json 时，我得到一个关于

的错误代码

JSON 中的意外令牌 { 位置

在做了一些研究后，我发现我必须发送一个 json 数组作为响应，而不是为每个事件打印一个 jsoned 行，否则我的 javascript 将无法解析它并将其放入对象中。

我的目标

从服务器获取数据并将其作为对象传递给 javascript，以便我可以遍历该对象并为每个事件创建一个 HTML 元素。

我是这个 JSON 的新手，不知何故我需要执行以下操作，但我似乎不知道如何创建一个 json 数组（在每个 json/ 末尾都有 [ ] 和 ,行。

[
    {"id": 0, "organizer": "Some Name", "eventStart": "09:30 AM", "eventEnd": "10:00 AM", "subject": "rental procedure", "attendees": "Some Name<br />Person 2<br />Person 3"},
    {"id": 1, "organizer": "Some Name", "eventStart": "09:30 AM", "eventEnd": "10:00 AM", "subject": "rental procedure", "attendees": "Some Name<br />Person 2<br />Person 3"},
    {"id": 2, "organizer": "Some Name", "eventStart": "09:30 AM", "eventEnd": "10:00 AM", "subject": "rental procedure", "attendees": "Some Name<br />Person 2<br />Person 3"}
]

Answer 1

...答案末尾的 JSON 数组不正确，但要生成数组，只需在 Python 中为 json.dumps 提供一个列表。类似json_data_list = []; ... ; json_data_list.append(json_data); ... print(json.dumps(json_data_list)); ...

Answer 2

您的 JSON 文件不正确。通常，您必须具有以下结构：

{
    "key1": [
        {
            "id": "blabla",
            "name": "Toto"
        },
        {
            "id": "blibli",
            "name": "Tata"
        }
    ],
    "key2": {
        "id": "value"
    },
    "key3": "value"
}

所以我认为你必须改变你的 JSON 数组，例如如下：

{
    [
        {
            "id": 0,
            "organizer": "Some Name",
            "eventStart": "09:30 AM",
            "eventEnd": "10:00 AM",
            "subject": "rental procedure",
            "attendees": "Some Name<br />Person 2<br />Person 3"
        },
        {
            "id": 1,
            "organizer": "Some Name",
            "eventStart": "09:30 AM",
            "eventEnd": "10:00 AM",
            "subject": "rental procedure",
            "attendees": "Some Name<br />Person 2<br />Person 3"
        },
        {
            "id": 2,
            "organizer": "Some Name",
            "eventStart": "09:30 AM",
            "eventEnd": "10:00 AM",
            "subject": "rental procedure",
            "attendees": "Some Name<br />Person 2<br />Person 3"
        }
    ]
}

您也可以决定不使用我上面建议的字典列表，而是使用 ID 值作为每个字典的键；在这种情况下，您有：

{
    "id0":{       
            "organizer": "Some Name",
            "eventStart": "09:30 AM",
            "eventEnd": "10:00 AM",
            "subject": "rental procedure",
            "attendees": "Some Name<br />Person 2<br />Person 3"
    },
    "id1":{       
            "organizer": "Some Name",
            "eventStart": "09:30 AM",
            "eventEnd": "10:00 AM",
            "subject": "rental procedure",
            "attendees": "Some Name<br />Person 2<br />Person 3"
    },
    "id2":{       
            "organizer": "Some Name",
            "eventStart": "09:30 AM",
            "eventEnd": "10:00 AM",
            "subject": "rental procedure",
            "attendees": "Some Name<br />Person 2<br />Person 3"
    }
}
