SpringBoot微信小程序授权登录

一、appId

1.1、自己是管理者：微信公众平台，申请或登录自己的微信小程序,在开发者管理中即可看到
2.2、自己是开发者：让管理员将自己加入到小程序开发者管理中，用管理者提供的appId和secret，否则没有开发权限

二、小程序登录页面

2.1、打开HBuilderX开发工具，新建一个uni-app项目

2.2、在项目根目录下新建config文件夹，创建config.js文件，配置后台访问路径

// 配置后台服务器访问地址：ip:端口/项目名
const hostUrl = ''
export default {// 本地持久化存储keyprojectKey: 'XinJiangBS',// api请求地址// #ifdef H5// H5 环境，配合menifest.json中的devServe配置来解决调试时的跨域问题baseUrl: process.env.NODE_ENV === 'development' ? '/dev' : hostUrl,// #endifbaseUrl: hostUrl,// 盐kSalt: 'XDSAKDSALMSD',
}

2.3、新建简单的login.vue页面，调用前端方法获取后台登录需要用的code信息

<button @click="toLogin">获取登录code</button>
// 可以将后台接口统一写在common.js中，页面统一引入
import { } from "@/api/common.js"
methods:{toLogin(){uni.getProvider({service:'oauth',success:(provider) => {uni.login({success:(loginCode) =>{console.log("loginCode",loginCode);// todo 调用后台登录接口，参数code}})}})},
}

2.4、下载微信开发者工具，并安装

2.5、配置HBuilderX,点击manifest.json，再点击微信小程序配置appid

2.6、配置运行小程序需要用到的微信开发开发者工具，点击HBuilder上面工具栏中的：工具—设置—运行配置，找到微信开发者工具工具路径，配置2.4中安装安装时的路径

三、java代码部分

1.新建微信小程序公用配置文件

@Component
@Slf4j
public class WxDataConfigure {/**小程序appId*/public static String appId = "";/**小程序的秘钥*/public static String ** = "";/**商户号*/public static String mch_id = "";/**商户支付秘钥V2*/public static String key = "";/**商户支付秘钥V3*/public static String keyV3 = "";/**退款用到*/public static String certUrl = "";/**商家转账到零钱*/public static String pemUrl = "";public static String privateKeyPath = "";public static String privateCertPath = "";public static String sn = "";/**商户证书序列号*/public static String serial_no = "";/**回调通知地址(需内网穿透测试)*/public static String notify_url = "";/**交易类型*/public static  String trade_type = "JSAPI";/**统一下单API接口链接*/public static String url = "https://api.mch.weixin.qq.com/pay/unifiedorder";/**查询订单API接口链接*/public static String query_url = "https://api.mch.weixin.qq.com/pay/orderquery";/**退款接口*/public static String refund_url = "https://api.mch.weixin.qq.com/v3/refund/domestic/refunds";/**退款回调接口*/public static String refund_notify_url = "";/**商家转账到零钱*/public static String batches_url = "https://api.mch.weixin.qq.com/v3/transfer/batches";/*** 预支付* @return*/public static WxPayService unifiedOrderWxPayService() {log.info("======================初始化微信支付接口服务开始======================");WxPayConfig payConfig = new WxPayConfig();payConfig.setAppId(appId);payConfig.setMchId(mch_id);payConfig.setMchKey(key);payConfig.setKeyPath(certUrl);payConfig.setTradeType(trade_type);WxPayService wxPayService = new WxPayServiceImpl();wxPayService.setConfig(payConfig);log.info("======================初始化微信支付接口服务完成======================");return wxPayService;}/*** 退款* @return*/public static WxPayService wxPayService() {//logger.info("======================初始化微信支付接口服务开始======================");WxPayConfig payConfig = new WxPayConfig();payConfig.setAppId(appId);payConfig.setMchId(mch_id);payConfig.setPrivateKeyPath(privateKeyPath);payConfig.setNotifyUrl(refund_notify_url);payConfig.setApiV3Key(keyV3);payConfig.setPrivateCertPath(privateCertPath);payConfig.setCertSerialNo(serial_no);payConfig.setMchKey(key);payConfig.setKeyPath(certUrl);payConfig.setTradeType(trade_type);WxPayService wxPayService = new WxPayServiceImpl();wxPayService.setConfig(payConfig);//logger.info("======================初始化微信支付接口服务完成======================");return wxPayService;}

2.调用微信服务器接口的请求方法类

public class HttpRequest {//连接超时时间，默认10秒private static final int socketTimeout = 10000;//传输超时时间，默认30秒private static final int connectTimeout = 30000;/*** 向指定URL发送GET方法的请求** @param url   发送请求的URL* @param param 请求参数，请求参数应该是 name1=value1&name2=value2 的形式。* @return URL 所代表远程资源的响应结果*/public static String sendGet(String url, String param) {String result = "";BufferedReader in = null;try {String urlNameString = url + "?" + param;URL realUrl = new URL(urlNameString);// 打开和URL之间的连接URLConnection connection = realUrl.openConnection();// 设置通用的请求属性connection.setRequestProperty("accept", "*/*");connection.setRequestProperty("connection", "Keep-Alive");connection.setRequestProperty("user-agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");// 建立实际的连接connection.connect();// 获取所有响应头字段Map<String, List<String>> map = connection.getHeaderFields();// 遍历所有的响应头字段for (String key : map.keySet()) {System.out.println(key + "--->" + map.get(key));}// 定义 BufferedReader输入流来读取URL的响应in = new BufferedReader(new InputStreamReader(connection.getInputStream()));String line;while ((line = in.readLine()) != null) {result += line;}} catch (Exception e) {System.out.println("发送GET请求出现异常！" + e);e.printStackTrace();}// 使用finally块来关闭输入流finally {try {if (in != null) {in.close();}} catch (Exception e2) {e2.printStackTrace();}}return result;}/*** post请求** @throws IOException* @throws ClientProtocolException* @throws NoSuchAlgorithmException* @throws KeyStoreException* @throws KeyManagementException* @throws UnrecoverableKeyException*/public static String sendPost(String url, Object xmlObj) throws ClientProtocolException, IOException, UnrecoverableKeyException, KeyManagementException, KeyStoreException, NoSuchAlgorithmException {HttpPost httpPost = new HttpPost(url);//解决XStream对出现双下划线的bugXStream xStreamForRequestPostData = new XStream(new DomDriver("UTF-8", new XmlFriendlyNameCoder("-_", "_")));xStreamForRequestPostData.alias("xml", xmlObj.getClass());//将要提交给API的数据对象转换成XML格式数据Post给APIString postDataXML = xStreamForRequestPostData.toXML(xmlObj);System.out.println(postDataXML);//得指明使用UTF-8编码，否则到API服务器XML的中文不能被成功识别StringEntity postEntity = new StringEntity(postDataXML, "UTF-8");httpPost.addHeader("Content-Type", "text/xml");httpPost.setEntity(postEntity);//设置请求器的配置RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(socketTimeout).setConnectTimeout(connectTimeout).build();httpPost.setConfig(requestConfig);HttpClient httpClient = HttpClients.createDefault();HttpResponse response = httpClient.execute(httpPost);HttpEntity entity = response.getEntity();String result = EntityUtils.toString(entity, "UTF-8");return result;}/*** http POST 请求** @param url:请求地址* @param body:     body实体字符串* @param certPath: 证书路径* @param password: 证书密码* @return*/public static String httpPostReflect(String url, String body, InputStream certPath, String password) {String xmlRes = "{}";HttpClient client = createSSLClientCert(certPath, password);HttpPost httpost = new HttpPost(url);try {//所有请求的body都需采用UTF-8编码
//            StringEntity entity = new StringEntity(body,"UTF-8");
//            httpost.setEntity(entity);//支付平台所有的API仅支持JSON格式的请求调用，HTTP请求头Content-Type设为application/jsonhttpost.addHeader("Connection", "keep-alive");httpost.addHeader("Accept", "*/*");httpost.addHeader("Content-Type", "application/json; charset=UTF-8");httpost.addHeader("Host", "api.mch.weixin.qq.com");httpost.addHeader("X-Requested-With", "XMLHttpRequest");httpost.addHeader("Cache-Control", "max-age=0");httpost.addHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0) ");//httpost.addHeader("Authorization",Configure.sn + " " + data);httpost.setEntity(new StringEntity(body, "UTF-8"));HttpResponse response = client.execute(httpost);//所有响应也采用UTF-8编码String result = EntityUtils.toString(response.getEntity(), "UTF-8");xmlRes = result;} catch (ClientProtocolException e) {System.out.println(e);} catch (UnknownHostException e) {System.out.println(e);} catch (IOException e) {System.out.println(e);}return xmlRes;}/*** 创建带证书的实例** @param certPath* @return*/public static CloseableHttpClient createSSLClientCert(InputStream certPath, String password) {try {KeyStore keyStore = KeyStore.getInstance("PKCS12");keyStore.load(certPath, password.toCharArray());certPath.close();SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {//信任所有public boolean isTrusted(X509Certificate[] chain,String authType) throws CertificateException {return true;}}).loadKeyMaterial(keyStore, password.toCharArray()).build();SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, new String[]{"TLSv1", "TLSv1.2"}, null, SSLConnectionSocketFactory.getDefaultHostnameVerifier());return HttpClients.custom().setSSLSocketFactory(sslsf).build();} catch (KeyManagementException e) {System.out.println(e);} catch (NoSuchAlgorithmException e) {System.out.println(e);} catch (KeyStoreException e) {System.out.println(e);} catch (FileNotFoundException e) {System.out.println(e);} catch (Exception e) {System.out.println(e);}return HttpClients.createDefault();}/*** 自定义证书管理器，信任所有证书** @author pc*/public static class MyX509TrustManager implements X509TrustManager {@Overridepublic void checkClientTrusted(java.security.cert.X509Certificate[] arg0, String arg1)throws CertificateException {}@Overridepublic void checkServerTrusted(java.security.cert.X509Certificate[] arg0, String arg1)throws CertificateException {}@Overridepublic java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;}}
}

3.微信登录方法，返回用户信息至前端

@Slf4j
@RestController
@RequestMapping("/wx/user")
public class WxController {/***  //GET https://api.weixin.qq.com/sns/jscode2session?appid=APPID&secret=SECRET&js_code=JSCODE&grant_type=authorization_code*  //https://api.weixin.qq.com/sns/jscode2session*/@GetMapping("/wxLogin")public Map<String,String> wxLogin(@RequestParam(name = "code",required = true) String code){//小程序登录参数Get请求String openidParams = "appid=" + WxDataConfigure.appId + "&secret=" + WxDataConfigure.secret + "&js_code=" + code + "&grant_type=" + "authorization_code";String openidUrl = "https://api.weixin.qq.com/sns/jscode2session";//获取接口调用凭证参数Get请求String accessTokenParams = "appid=" + WxDataConfigure.appId + "&secret=" + WxDataConfigure.secret + "&grant_type=" + "client_credential";String accessTokenUrl = "https://api.weixin.qq.com/cgi-bin/token";//http请求微信服务器String openIdResult = HttpRequest.sendGet(openidUrl, openidParams);String accessTokenResult = HttpRequest.sendGet(accessTokenUrl, accessTokenParams);JSONObject openIdJson = JSONObject.parseObject(openIdResult);JSONObject accessTokenJson = JSONObject.parseObject(accessTokenResult);//获取openIdString openid =(String) openIdJson.get("openid");//会话秘钥String session_key =(String) openIdJson.get("session_key");//获取到的凭证String access_token =(String) accessTokenJson.get("access_token");Integer expiresIn =(Integer) accessTokenJson.get("expires_in");Map<String, String> infoMap = new HashMap<>();infoMap.put("openid",openid);infoMap.put("session_key",session_key);infoMap.put("access_token",access_token);infoMap.put("expiresIn",expiresIn.toString());return infoMap;}
}
