log(resultString); // 输出: Hello World 在这个示例中,我们首先定义了一个hexStringToUint8Array函数,它接受一个十六进制字符串作为参数。然后,我们去除字符串中的空白字符,将其拆分成每两个字符一组的数组,并将每个十六进制数转换为对应的十进制数。最后,我们使用Uint8Array.from()方法创建一个Uint8Array对象,并将其返回。为了验证函数...
下面是另一个更长的实现,更容易理解,但本质上做同样的事情: function buf2hex(buffer) { // buffer is an ArrayBuffer // create a byte array (Uint8Array) that we can use to read the array buffer const byteArray = new Uint8Array(buffer); // for each element, we want to get its two-di...
letmyString="Hello, world!"; 1. 步骤2: 使用TextEncoder编码字符串 在现代浏览器中,你可以使用TextEncoder接口来将字符串编码为字节。 constencoder=newTextEncoder();letencoded=encoder.encode(myString); 1. 2. 步骤3: 转换结果为字节数组 TextEncoder的encode方法返回一个Uint8Array,这是一个字节数组。 le...
