Question

用java调用https webservice，该怎么处理

Answer 1

public String sendPost(String url, String param) {
        String requestData = param;//参数
        String requsetString = url;//远程接口地址
        // First create a trust manager that won't care.
        //信任任何证书
        X509TrustManager trustManager = new X509TrustManager() {

            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

                // Don't do anything.
            }


            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

                // Don't do anything.
            }


            public X509Certificate[] getAcceptedIssuers() {

                // Don't do anything.
                return null;
            }

        };
        // 把信任证书放到ssl中
        SSLContext sslcontext;
        String result = "";
        try {
            sslcontext = SSLContext.getInstance("SSL");
            sslcontext.init(null, new TrustManager[] {trustManager}, null);

            // Use the above SSLContext to create your socket factory
            // (I found trying to extend the factory a bit difficult due to a
            // call to createSocket with no arguments, a method which doesn't
            // exist anywhere I can find, but hey-ho).
            SSLSocketFactory sf = new SSLSocketFactory(sslcontext);
            sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

            DefaultHttpClient httpclient = new DefaultHttpClient();
            httpclient.getConnectionManager().getSchemeRegistry().register(new Scheme("https", sf, VariableTool.HTTP_NUM));

            HttpPost httpPost = new HttpPost(requsetString);
            
            // 执行https请求
            httpPost.setHeader("Authorization", "basic " + "dGNsb3VkYWRtaW46dGNsb3VkMTIz");
            httpPost.setHeader("Content-type", "application/xml");

            StringEntity reqEntity;

            // 将请求参数封装成HttpEntity
            reqEntity = new StringEntity(requestData,"UTF-8");
            BufferedHttpEntity bhe = new BufferedHttpEntity(reqEntity);
            httpPost.setEntity(bhe);
            HttpResponse response = httpclient.execute(httpPost);
            HttpEntity resEntity = response.getEntity();
            InputStreamReader reader = new InputStreamReader(resEntity.getContent());

            char[] buff = new char[1024];
            int length = 0;
            while ((length = reader.read(buff)) != -1) {
                result += new String(buff, 0, length);
            }
            
            logger.debug("调用ws接口返回：" + result);
            httpclient.getConnectionManager().shutdown();

        } catch (Exception e) {
            e.printStackTrace();
            return "";
        }
        return result;
    }
result 就是远程接口返回的接口
