在现代网络应用中,确保数据安全和隐私至关重要。 保护数据库 ID 或 URL 等敏感信息的一种有效方法是使用哈希德该工具是一个 JavaScript 加密库,可将数字数据转换为唯一、可逆和加密的哈希值。 本文将探讨如何将 Hashids 无缝集成到 React 应用程序中,以混淆和解码标识符。
Hashids 是一个小巧但功能强大的库,可将数字数据转换为散列字符串。 主要目标是模糊数字标识符,防止敏感信息泄露。 这种转换是可逆的,允许在需要时检索原始数字数据。 Hashids 是一个 JavaScript 库,用于从数字中生成类似于 YouTube 的 ID,对敏感数据进行编码,或安全地向用户公开数据库 ID,或只是混淆数字中的 ID。
要将 Hashids 集成到您的 React 应用程序中,请按照以下步骤操作:
首先,在 React 项目中通过 npm 安装 Hashids:
npm install hashids
or
yarn add hashids
npm install hashids
or
yarn add hashids
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npm install hashids @or yarn add hashids
在 React 组件或实用程序文件中,用盐和可选的最小哈希长度初始化一个新的 Hashids 实例:
import { useState, useEffect } from 'react';
import Hashids from 'hashids';
const MyComponent = () => {
const [hashids, setHashids] = useState(null);
useEffect(() => {
const initHashids = new Hashids('your_salt_here', 8); // Replace 'your_salt_here' with your actual salt or configure custom alphabet
setHashids(initHashids);
}, []);
// Other component logic here
return (
<div>
{/* Your JSX content */}
</div>
);
};
export default MyComponent;
import { useState, useEffect } from 'react';
import Hashids from 'hashids';
const MyComponent = () => {
const [hashids, setHashids] = useState(null);
useEffect(() => {
const initHashids = new Hashids('your_salt_here', 8); // Replace 'your_salt_here' with your actual salt or configure custom alphabet
setHashids(initHashids);
}, []);
// Other component logic here
return (
<div>
{/* Your JSX content */}
</div>
);
};
export default MyComponent;
import
If True Then
useState, useEffect
End If
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'from 'react'; import Hashids from 'hashids'; const MyComponent = () => { const [hashids, setHashids] = useState(Nothing); useEffect(() => { const initHashids = New Hashids('your_salt_here', 8); setHashids(initHashids); }, []); Return(<div> {} </div>); }; export default MyComponent;
用唯一字符串替换 `'your_salt_here'`(盐分)您可以用它来自定义哈希输出。
初始化后,您可以使用 Hashids 对数字数据进行编码和解码。 例如,对数据库 ID 进行编码:
const encodedId = hashids.encode(12345); // Example: 'B0zGbvA9' non sequential ids
const encodedId = hashids.encode(12345); // Example: 'B0zGbvA9' non sequential ids
const encodedId = hashids.encode(12345) ' Example: 'B0zGbvA9' non sequential ids
并解码回原始 ID:
const decodedIds = hashids.decode('B0zGbvA9'); // Example: [12345]
const decodedIds = hashids.decode('B0zGbvA9'); // Example: [12345]
const decodedIds = hashids.decode( 'B0zGbvA9'); ' Example: [12345]
必要时在 React 组件中集成 Hashids。 例如,将散列 ID 作为道具传递:
const MyComponent = ({ id }) => {
const encodedId = hashids ? hashids.encode(id) : '';
return (
<div>
<p>Encoded ID: {encodedId}</p>
{/* Other JSX content */}
</div>
);
};
const MyComponent = ({ id }) => {
const encodedId = hashids ? hashids.encode(id) : '';
return (
<div>
<p>Encoded ID: {encodedId}</p>
{/* Other JSX content */}
</div>
);
};
'INSTANT VB TODO TASK: Lambda expressions and anonymous methods are not converted by Instant VB if local variables of the outer method are referenced within the anonymous method:
const MyComponent = ({ id }) =>
If True Then
'INSTANT VB TODO TASK: The following line uses invalid syntax:
' const encodedId = hashids ? hashids.encode(id) : ''; Return(<div> <p> Encoded ID: {encodedId}</p> {} </div>); };

安装IronPDF要翻译 NPM 软件包,请使用以下命令:
yarn add @ironsoftware/ironpdf @ironsoftware/ironpdf-engine-windows-x64
yarn add @ironsoftware/ironpdf @ironsoftware/ironpdf-engine-windows-x64
IRON VB CONVERTER ERROR developers@ironsoftware.com
安装依赖项:首先,创建一个新的 Next.js 项目(如果你还没有)使用以下命令:参阅这里
npx create-next-app@latest hashids-pdf --use-npm --example "https://github.com/vercel/next-learn/tree/main/basics/learn-starter"
npx create-next-app@latest hashids-pdf --use-npm --example "https://github.com/vercel/next-learn/tree/main/basics/learn-starter"
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'npx create-@next-app@latest hashids-pdf --use-npm --example "https://github.com/vercel/next-learn/tree/main/basics/learn-starter"
接下来,导航到你的项目目录:
cd hashids-pdf
cd hashids-pdf
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'cd hashids-pdf
安装所需的软件包:
yarn add @ironsoftware/ironpdf @ironsoftware/ironpdf-engine-windows-x64
yarn add hashids
yarn add @ironsoftware/ironpdf @ironsoftware/ironpdf-engine-windows-x64
yarn add hashids
'INSTANT VB TODO TASK: The following line uses invalid syntax:

现在,让我们创建一个使用生成PDF的简单示例IronPDF. 在您的Next.js组件中(例如,pages/index.tsx)添加以下代码
PDF 生成 API:第一步是创建一个后端 API 来生成 PDF 文档。 由于 IronPdf 只在服务器端运行,我们需要创建一个 API,以便在用户想要生成 PDF 时调用。 在 pages/api/pdf.js 路径下创建一个文件,并添加以下内容。
IronPDF需要许可证密钥,您可以从许可证页面Please provide the content you would like translated into Chinese along with the code where it should be placed.
// pages/api/pdf.js
import {IronPdfGlobalConfig, PdfDocument} from "@ironsoftware/ironpdf";
// Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Your license key";
export default async function handler(req, res) {
try {
const initHashids = new Hashids('IronPDF Is Awesome and this is the salt', 8);
const f = req.query.f;
const l = initHashids.encode(f);
let content = "<h1>Demo Hashids and Generate PDF Using IronPDF</h1>"
content+="<p>Input:"+f+"</p>";
content+="<p>HashID:"+l+"</p>";
const pdf = await PdfDocument.fromHtml(content);
const data = await pdf.saveAsBuffer();
console.error("data PDF:", data);
res.setHeader("Content-Type", "application/pdf");
res.setHeader(
"Content-Disposition",
"attachment; filename=awesomeIron.pdf",
);
res.send(data);
} catch (error) {
console.error("Error generating PDF:", error);
res.status(500).end();
}
}
// pages/api/pdf.js
import {IronPdfGlobalConfig, PdfDocument} from "@ironsoftware/ironpdf";
// Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Your license key";
export default async function handler(req, res) {
try {
const initHashids = new Hashids('IronPDF Is Awesome and this is the salt', 8);
const f = req.query.f;
const l = initHashids.encode(f);
let content = "<h1>Demo Hashids and Generate PDF Using IronPDF</h1>"
content+="<p>Input:"+f+"</p>";
content+="<p>HashID:"+l+"</p>";
const pdf = await PdfDocument.fromHtml(content);
const data = await pdf.saveAsBuffer();
console.error("data PDF:", data);
res.setHeader("Content-Type", "application/pdf");
res.setHeader(
"Content-Disposition",
"attachment; filename=awesomeIron.pdf",
);
res.send(data);
} catch (error) {
console.error("Error generating PDF:", error);
res.status(500).end();
}
}
' pages/api/pdf.js

IronPdfGlobalConfig, PdfDocument
End If
from "@ironsoftware/ironpdf"
' Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Your license key"
