Javascript 如何在react组件中传递iframe

我试图在react组件中创建一个简单的iframe，它将显示一个google地图位置。我目前正在像这样硬编码src

this.state.features.map(function(school){
    return(
        <div>
            {school.name}
            <div>
            <iframe frameBorder="0" style={{ width: "100%", height: "450"}} 
                src="https://www.google.com/maps/embed/v1/place?q=40.7127837,-74.0059413&amp;key=AIzaSyCc3zoz5TZaG3w2oF7IeR-fhxNXi8uywNk">
            </iframe>
            </div>
        </div>
    )
})

然后像这样动态地传递src

const MY_API = AIzaSyCc3zoz5TZaG3w2oF7IeR-fhxNXi8uywNk

let _url = "https://www.google.com/maps/embed/v1/place?q=40.7127837,-74.0059413&key="+MY_API;

<iframe frameBorder="0" style={{ width: "100%", height: "450"}} 
        src={_url}>
</iframe>

但是现在我得到了以下错误

Google Maps API服务器拒绝了您的请求。无效的请求。 意外参数“amp%3Bkey”

不确定错误消息是关于什么的。请帮忙

试试这个（我还不能对问题发表评论）

上面使用的是导出常量映射=（profile）=>{ var纬度=坐标。纬度； var经度=坐标。经度； const MY_API='AIzaSyCc3zoz5TZaG3w2oF7IeR-fhxNXi8uywNk'； 变量querystring='q='+纬度+'，'+经度； 让_url=`https://www.google.com/maps/embed/v1/place?key=${MY_API}&`+querystring； 返回( ) };

我不知道这是否是最好的选择：

export const maps = (profile) => {
