南京水费脚本-免抓cookie

freefitter

之前的水费是需要自己去抓Cookie，然后填在配置文件中，现在不需要了，使用了带带弟弟OCR通用验证码识别SDK免费开源版，来进行验证码识别，并进行模拟登陆。这边只取了水费信息，如果需要其他的可以自己修改。然后在Node-Red中执行这个脚本就可以了。
之前插件的地址 南京水费插件，也做了更新。

    response = requests.request("POST", url, headers=headers, data=payload)
    print(response.text)

可以使用Node-Red直接调用 exec 节点调用。然后生成MQTT传感器。

function toDecimal2(x) {
    var f = Math.round(x * 100) / 100;
    var s = f.toString();
    var rs = s.indexOf('.');
    if (rs < 0) {
        rs = s.length;
        s += '.';
    }
    while (s.length <= rs + 2) {
        s += '0';
    }
    return s;
}

const prefix = "home/sensor/water_fee"
let msg_config = []
msg_config = [
    {
        "topic": "homeassistant/sensor/water_fee/config",
        "payload": {
            "~": prefix.replace("button", "sensor"),
            "name": "water_fee",
            "state_topic": "~/state",
            "unique_id": "water_fee",
            "icon": "mdi:water",
            "json_attributes_topic": "~/info"
        }
    },
    {
        "topic": `${prefix.replace("button", "sensor")}/state`,
        "payload": toDecimal2(msg.payload.waterFee)
    },
    {
        "topic": `${prefix.replace("button", "sensor")}/info`,
        "payload": msg.payload
    }
]

return [msg_config];

我又来了 江宁不算南京 哈哈
江宁水务抓了cookie用了好久了 非常稳定
