关于post请求发送数组

网址: http://jzxxgk.jian.gov.cn/xxgk-list-xzsqfwzxsqchxc.html

ajax: http://jzxxgk.jian.gov.cn/api-ajax_list-3.html, 参数参考下面的函数

    function show_lists(page) {
        $.ajax({
            url: "api-ajax_list-" + page + ".html",
            type: "post",
            async: false,
            data: {
                "ajax_type": ["12_xxgk", "95446", 12, "xxgk", "Y-m-d", 22, 20, ["inputtime DESC"], "..."],
                "is_ds": 1
            },
            dataType: "JSON",
            success: function (data) {
            }
        })
    }

请求参数

一般post请求把数据往表单中一放, 就可以了(文章中的url不需要设置header)

import requests


data = {
    "ajax_type": ["12_xxgk", "95446", 12, "xxgk", "Y-m-d", 22, 20, ["inputtime DESC"], "..."],
    "is_ds": 1
}

if __name__ == '__main__':
    url = 'http://jzxxgk.jian.gov.cn/api-ajax_list-3.html'
    res = requests.post(url=url, data=data)
    print(res.json())

然并卵, 并没有出现想要的结果

{
    "status":0,
    "msg":"新闻或信息公开表不存在"
}

修改一下请求参数试试

import requests

datas = {
    "ajax_type[0]": "12_xxgk",
    "ajax_type[1]": "95464",
    "ajax_type[2]": 12,
    "ajax_type[3]": "xxgk",
    "ajax_type[4]": "Y-m-d",
    "ajax_type[5]": 22,
    "ajax_type[6]": 20,
    "ajax_type[7]": ["inputtime DESC"],
    "ajax_type[8]": "...",
    "is_ds": "1",
}

if __name__ == '__main__':
    url = 'http://jzxxgk.jian.gov.cn/api-ajax_list-3.html'
    res = requests.post(url=url, data=datas)
    print(res.text)

再看一下结果, 数据有点多, 就不全贴出来了

{
    "data":[
        {
            "id":"9956094",
            "catid":"95464",
            "title":"关于中心城区公园改造提升工程环境影响 报告表...",
            "slug_title":"",

       ...
    ],

}

原因

为啥用下标写就可以了呢, 为了保持顺序, 后台可能是通过下标来获取信息的吧

正常请求

将参数拷贝到postman中再发送

参数的顺序发生了变化, 后台自然就获取不到正确的值了, 也就不会有结果了

附加

下标为7的元素也是一个列表, 也是一样的写法

datas_2 = {
    "ajax_type[0]": "12_xxgk",
    "ajax_type[1]": "93745",
    "ajax_type[2]": 12,
    "ajax_type[3]": "xxgk",
    "ajax_type[4]": "Y-m-d",
    "ajax_type[5]": 22,
    "ajax_type[6]": 20,
    "ajax_type[7][0]": "is_top DESC",
    "ajax_type[7][2]": "displayorder DESC",
    "ajax_type[7][3]": "inputtime DESC",
    "ajax_type[8]": "...",
    "is_ds": "1",
}
