企业微信上传临时素材文件

1.控制层

    /*** 上传临时素材*/@ResponseBody@PostMapping("/uploadResource")public BaseResponse uploadResource(MultipartHttpServletRequest param,@RequestParam("accessToken") String token,@RequestParam("type")String type) throws Exception{return BaseResponse.Builder.build(weixinService.uploadResource(param,token,type));}

2.Service层

    /*** 上传临时素材* @param param* @return*/Map<String, Object> uploadResource(MultipartHttpServletRequest param,String accessToken,String type)throws Exception ;

3.实现层

    @Overridepublic Map<String, Object> uploadResource(MultipartHttpServletRequest param,String accessToken,String type)throws Exception  {/*** 1.封装Multipart参数*/MultipartFile file = param.getFile("file");/*** 2.调用上传临时素材接口*/String result = uploadFile(M2F(file), type, accessToken);log.info("getMessageResult result=" + result);/*** 3.返回上传临时素材接口响应数据*/Map<String,Object> map=new HashMap<>();JSONObject resultObject = new JSONObject(result);map.put("errcode",resultObject.getInt("errcode"));map.put("errmsg",resultObject.get("errmsg"));map.put("media_id",resultObject.get("media_id"));return map;}/*** MultipartFile文件转File文件* @param file* @return* @throws Exception*/public File M2F(MultipartFile file) throws Exception {File f=File.createTempFile(UUID.randomUUID().toString(), "." + FilenameUtils.getExtension(file.getOriginalFilename()));file.transferTo(f);return f;}/*** 处理请求数据* @param file* @param fileType * @param accessToken* @return*/public String uploadFile(File file, String fileType,String accessToken){RestTemplate restTemplate = new RestTemplate(new HttpsClientRequestFactory());String url = "https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token="+accessToken+"&type="+fileType;HttpHeaders headers = new HttpHeaders();MediaType type = MediaType.parseMediaType("multipart/form-data");headers.setContentType(type);headers.setContentLength(file.length());headers.setContentDispositionFormData("media",file.getName());MultiValueMap<String,Object> param = new LinkedMultiValueMap<>();FileSystemResource resource = new FileSystemResource(file.getPath());param.add("file",resource);HttpEntity<MultiValueMap<String,Object>> formEntity = new HttpEntity<>(param, headers);ResponseEntity<String> data = restTemplate.postForEntity(url,formEntity,String.class);String body = data.getBody();return body;}

4.HttpClient类

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;

public class HttpsClientRequestFactory extends SimpleClientHttpRequestFactory {@Overrideprotected void prepareConnection(HttpURLConnection connection, String httpMethod) {try {if (!(connection instanceof HttpsURLConnection)) {throw new RuntimeException("An instance of HttpsURLConnection is expected");}HttpsURLConnection httpsConnection = (HttpsURLConnection) connection;TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {@Overridepublic void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic void checkServerTrusted(X509Certificate[] x509Certificates, String s) throwsCertificateException {}@Overridepublic X509Certificate[] getAcceptedIssuers() {return null;}}};SSLContext sslContext = SSLContext.getInstance("TLS");sslContext.init(null, trustAllCerts, new java.security.SecureRandom());httpsConnection.setSSLSocketFactory(new MyCustomSSLSocketFactory(sslContext.getSocketFactory()));httpsConnection.setHostnameVerifier(new HostnameVerifier() {@Overridepublic boolean verify(String s, SSLSession sslSession) {return true;}});super.prepareConnection(httpsConnection, httpMethod);} catch (Exception e) {e.printStackTrace();}}/*** We need to invoke sslSocket.setEnabledProtocols(new String[] {"SSLv3"});* see http://www.oracle.com/technetwork/java/javase/documentation/cve-2014-3566-2342133.html (Java 8 section)*/// SSLSocketFactory用于创建 SSLSocketsprivate static class MyCustomSSLSocketFactory extends SSLSocketFactory {private final SSLSocketFactory delegate;public MyCustomSSLSocketFactory(SSLSocketFactory delegate) {this.delegate = delegate;}// 返回默认启用的密码套件。除非一个列表启用，对SSL连接的握手会使用这些密码套件。// 这些默认的服务的最低质量要求保密保护和服务器身份验证@Overridepublic String[] getDefaultCipherSuites() {return delegate.getDefaultCipherSuites();}// 返回的密码套件可用于SSL连接启用的名字@Overridepublic String[] getSupportedCipherSuites() {return delegate.getSupportedCipherSuites();}@Overridepublic Socket createSocket(final Socket socket, final String host, final int port,final boolean autoClose) throws IOException {final Socket underlyingSocket = delegate.createSocket(socket, host, port, autoClose);return overrideProtocol(underlyingSocket);}@Overridepublic Socket createSocket(final String host, final int port) throws IOException {final Socket underlyingSocket = delegate.createSocket(host, port);return overrideProtocol(underlyingSocket);}@Overridepublic Socket createSocket(final String host, final int port, final InetAddress localAddress,final int localPort) throwsIOException {final Socket underlyingSocket = delegate.createSocket(host, port, localAddress, localPort);return overrideProtocol(underlyingSocket);}@Overridepublic Socket createSocket(final InetAddress host, final int port) throws IOException {final Socket underlyingSocket = delegate.createSocket(host, port);return overrideProtocol(underlyingSocket);}@Overridepublic Socket createSocket(final InetAddress host, final int port, final InetAddress localAddress,final int localPort) throwsIOException {final Socket underlyingSocket = delegate.createSocket(host, port, localAddress, localPort);return overrideProtocol(underlyingSocket);}private Socket overrideProtocol(final Socket socket) {if (!(socket instanceof SSLSocket)) {throw new RuntimeException("An instance of SSLSocket is expected");}((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1"});return socket;}}}

如果在调用的时候出现了javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)异常需要配置JM的参数设置,经过百度查询

原因：配置文件中禁用 TLSv1, TLSv1.1

修改如下:

把..\Java\jdk-11.0.11\conf\security文件下的java.security文件

将：

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
include jdk.disabled.namedCurves

替换为：

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
include jdk.disabled.namedCurves
