介绍
FingerprintJS 是一个源代码可用的客户端浏览器指纹识别库,可查询浏览器属性并根据这些属性计算哈希访客标识符。与 Cookie 和本地存储不同,指纹在隐身/隐私模式下保持不变,即使浏览器数据被清除也是如此。

测试用例

<script>
// Initialize the agent at application startup.
const fpPromise = import('https://openfpcdn.io/fingerprintjs/v4')
.then(FingerprintJS => FingerprintJS.load())
// Get the visitor identifier when you need it.
fpPromise
.then(fp => fp.get())
.then(result => {
// This is the visitor identifier:
const visitorId = result.visitorId
console.log(visitorId)
})
.catch(error => console.error(error))
</script>
