调用和风天气API，页脚显示天气预报

[jesustoachild]

1. 和风天气API和KEY申请，参考：
   https://github.com/c1pher-cn/heweather

2 显示效果如下：

<div class="weather-panel">
    <span id="weather-info"></span>
</div>

<style>
    .weather-panel {
        color: white;
        display: flex;
        flex-direction: column;
        align-items: flex-end;
        text-align: right;
    }

    #weather-info {
        line-height: 1.2;
    }

    .weather-main {
        display: flex;
        justify-content: space-between;
        width: 100%;
        margin-bottom: 6px;
    }

    .weather-main-left {
        font-size: 16px;
    }

    .temp-and-forecast {
        display: flex;
        justify-content: space-between;
        width: 100%;
        font-size: 12px;
        margin-bottom: 6px;
    }

    .temp-range {
        text-align: left;
    }

    .hourly-forecast {
        text-align: right;
        padding-left: 8ch; /* 添加 8 个字符宽度的空隙 */
    }

    .wind-info {
        display: flex;
        justify-content: space-between;
        width: 100%;
        font-size: 12px;
        margin-bottom: 6px;
    }

    .wind-info span {
        flex: 1;
    }

    .air-quality {
        text-align: left;
    }
</style>

大神，用不了啊，完全没反应啊，打开检查第一句就是错误，有没有具体点的使用办法啊
