接口簽名目的是為了，確保請(qǐng)求參數(shù)不會(huì)被篡改，請(qǐng)求的數(shù)據(jù)是否已超時(shí)，數(shù)據(jù)是否重復(fù)提交等。

接口簽名示意圖

客戶端提交請(qǐng)求時(shí)，將以下參數(shù)按照約定簽名方式進(jìn)行簽名，隨后將參數(shù)和簽名一同提交服務(wù)端：

1.請(qǐng)求頭部分（header）appid：針對(duì)不同的調(diào)用方分配不同的appid。noce：請(qǐng)求的流水號(hào)，防止重復(fù)提交。timestamp：請(qǐng)求時(shí)間戳，驗(yàn)證請(qǐng)求是否已超時(shí)失效。

2.數(shù)據(jù)部分Path：按照path中的參數(shù)將所有key=value進(jìn)行拼接。Query：按照所有key=value進(jìn)行拼接。Form：按照所有key=value進(jìn)行拼接Body：Json，按照所有key=value進(jìn)行拼接。String，整個(gè)字符串作為一個(gè)拼接。

簽名

服務(wù)端提接收交請(qǐng)求后，同樣通過接收的“請(qǐng)求頭部分”、“數(shù)據(jù)部分”的參數(shù)進(jìn)行拼接。隨后驗(yàn)證客戶端提交的簽名是否正確。

客戶端（Vue）首先需要安裝“jsrsasign”庫，以便實(shí)現(xiàn) RSA 加密、解密、簽名、驗(yàn)簽等功能。官方地址：http://kjur.github.io/jsrsasign/執(zhí)行以下命令：

npm install jsrsasign -save

安裝完成后，封裝sign.js

import {KJUR, KEYUTIL, hex2b64, b64tohex} from ’jsrsasign’// 簽名算法const ALGORITHM = ’SHA256withRSA’// 私鑰簽名const RSA_SIGN = (privateKey, src) => { const signature = new KJUR.crypto.Signature({’alg’: ALGORITHM}) // 來解析密鑰 const priKey = KEYUTIL.getKey(privateKey) signature.init(priKey) // 傳入待簽明文 signature.updateString(src) const a = signature.sign() // 轉(zhuǎn)換成base64，返回 return hex2b64(a) }// 公鑰驗(yàn)簽const RSA_VERIFY_SIGN = (publicKey, src, data) => { const signature = new KJUR.crypto.Signature({’alg’: ALGORITHM, ’prvkeypem’: publicKey}) signature.updateString(src) return signature.verify(b64tohex(data))}export { RSA_SIGN, RSA_VERIFY_SIGN}

客戶端（Vue）通過sign.js進(jìn)行加簽、驗(yàn)簽。

服務(wù)端（Spring boot）接收請(qǐng)求后，需要對(duì)數(shù)據(jù)和簽名，進(jìn)行驗(yàn)證。

首先引入依賴——hutool工具包，Hutool是一個(gè)Java工具包，也只是一個(gè)工具包，它幫助我們簡(jiǎn)化每一行代碼，減少每一個(gè)方法，讓Java語言也可以“甜甜的”。

官網(wǎng)地址：https://www.hutool.cn/

在pom.xml下增加如下配置：

<dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.3.5</version></dependency>

服務(wù)端（Spring boot）首先要獲取客戶端（Vue）請(qǐng)求的數(shù)據(jù)，上文已經(jīng)描述了請(qǐng)求的數(shù)據(jù)有兩部分，分別是“請(qǐng)求頭部分”、“數(shù)據(jù)部分”。所以需要配置攔截器，對(duì)以上兩部分進(jìn)行獲取。

配置攔截器（MyInterceptor.java），代碼如下：

import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Component;import org.springframework.util.StreamUtils;import org.springframework.web.servlet.HandlerInterceptor;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;@Slf4j@Componentpublic class MyInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {//獲取請(qǐng)求參數(shù)String queryString = request.getQueryString();log.info('請(qǐng)求參數(shù):{}', queryString);// 獲取headerlog.info('key:{}',request.getHeader('timestamp'));MyHttpServletRequestWrapper myRequestWrapper = new MyHttpServletRequestWrapper(request);//獲取請(qǐng)求bodybyte[] bodyBytes = StreamUtils.copyToByteArray(myRequestWrapper.getInputStream());String body = new String(bodyBytes, request.getCharacterEncoding());log.info('請(qǐng)求體：{}', body);return true; }}

在獲取“請(qǐng)求體body”時(shí)，由于“HttpServletRequest”只能讀取一次，攔截器讀取后，后續(xù)Controller在讀取時(shí)為空，所以需要重寫HttpServletRequestWrapper：

import org.springframework.util.StreamUtils;import javax.servlet.ReadListener;import javax.servlet.ServletInputStream;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletRequestWrapper;import java.io.*;public class MyHttpServletRequestWrapper extends HttpServletRequestWrapper { /** * 緩存下來的HTTP body */ private byte[] body; public MyHttpServletRequestWrapper(HttpServletRequest request) throws IOException {super(request);body = StreamUtils.copyToByteArray(request.getInputStream()); } @Override public ServletInputStream getInputStream() throws IOException {InputStream bodyStream = new ByteArrayInputStream(body);return new ServletInputStream(){ @Override public int read() throws IOException {return bodyStream.read(); } @Override public boolean isFinished() {return false; } @Override public boolean isReady() {return true; } @Override public void setReadListener(ReadListener readListener) { }}; } @Override public BufferedReader getReader() throws IOException {return new BufferedReader(new InputStreamReader(getInputStream())); }}

之后，需要?jiǎng)?chuàng)建過濾器，將“MyHttpServletRequestWrapper” 替換“ServletRequest”，代碼如下：

import lombok.extern.slf4j.Slf4j;import javax.servlet.*;import javax.servlet.http.HttpServletRequest;import java.io.IOException;@Slf4jpublic class RepeatedlyReadFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {ServletRequest requestWrapper = null;if(servletRequest instanceof HttpServletRequest) { requestWrapper = new MyHttpServletRequestWrapper((HttpServletRequest) servletRequest);}if(requestWrapper == null) { filterChain.doFilter(servletRequest, servletResponse);} else { filterChain.doFilter(requestWrapper, servletResponse);} } @Override public void destroy() { }}

之后創(chuàng)建自定義配置，CorsConfig.java，將過濾器、攔截器加入配置：

import com.xyf.interceptor.MyInterceptor;import com.xyf.interceptor.RepeatedlyReadFilter;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.web.servlet.FilterRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;@Configurationpublic class CorsConfig extends WebMvcConfigurationSupport { private MyInterceptor myInterceptor; @Autowired public CorsConfig (MyInterceptor myInterceptor){this.myInterceptor = myInterceptor; } // 注冊(cè)過濾器 @Bean public FilterRegistrationBean<RepeatedlyReadFilter> repeatedlyReadFilter() {FilterRegistrationBean registration = new FilterRegistrationBean();RepeatedlyReadFilter repeatedlyReadFilter = new RepeatedlyReadFilter();registration.setFilter(repeatedlyReadFilter);registration.addUrlPatterns('/*');return registration; } @Override protected void addInterceptors(InterceptorRegistry registry) {// addPathPatterns添加需要攔截的命名空間；// excludePathPatterns添加排除攔截命名空間registry.addInterceptor(myInterceptor).addPathPatterns('/**');//.excludePathPatterns('/api/sys/login') }}

最后，完成驗(yàn)簽，代碼如下：

import cn.hutool.core.codec.Base64;import cn.hutool.crypto.SecureUtil;import cn.hutool.crypto.asymmetric.Sign;import cn.hutool.crypto.asymmetric.SignAlgorithm;byte[] data = '我是一段測(cè)試字符串2'.getBytes();String publicKey = 'MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC35wxzdTzseajkYL06hEKBCEJun' +'JQ/nySId2oTnsxbLiSTEjpAESSbML1lqkKaIwjrSFZzyLMH6DirsoEQcATqqoCDUn' +'/H9QNVb5jMSAxxdQusQkTWz6k07bEuy1ppVjpGxNi8o2OGNd+lwPC/hOSDR7lpfmn' +'aXLIjEwKSXzil7YAHQIDAQAB';Sign sign = SecureUtil.sign(SignAlgorithm.SHA256withRSA,null,publicKey);//客戶端傳來的簽名String qm = 'IhY3LNuFn0isud1Pk6BL2eJV3Jl/UzDCYsdG9CYyJwOGqwnzStsv/RiYLnVP4bnQh1NRPMazY6ux/5Zz5Ypcx6RI5W1p5BDbO2afuIZX7x/eIu5utwsanhbxEfvm3XOsyuTbnMDh6BQUrXb4gUz9qgt9IXWjQdqnQRRv3ywzWcA=';byte[] signed = Base64.decode(qm);//驗(yàn)證簽名boolean verify = sign.verify(data, signed);3、公鑰、私鑰生成

可通過一些網(wǎng)站在線生成公鑰、私鑰網(wǎng)址：https://www.bejson.com/enc/rsa/

bejson在線生成公鑰、私鑰

由于客戶端加簽、服務(wù)端驗(yàn)簽。所以加簽、驗(yàn)簽的方式務(wù)必一致，否則將無法驗(yàn)證簽名。Vue、Java有不同的簽名工具庫，使用前要做好測(cè)試。
