Android HttpURLConnection Post 参数 （https）

声明utf－8:

public static String CHARSET_UTF8 = HTTP.UTF_8;

eg：登陆请求方法，通过接口返回结果：

public static void login(String username, String password, ResponseCallbackHandler responseCallbackHandler) {
        Map<String, String> params = new HashMap<>();
        params.put("username", username);
        params.put("password", password);
        post("https:/..../login", params, responseCallbackHandler);
    }

post请求执行前，网络判断，以及url参数转换：

private static void post(final String url, Map<String, String> _params, final ResponseCallbackHandler responseCallbackHandler) {

        if (!NetworkUtils.isNetworkConnected(RunnerApp.getContext())) {
            if (responseCallbackHandler != null) {
                responseCallbackHandler.onNetworkError();
                responseCallbackHandler.onFinish();
            }
            return;
        }
        final String params = map2Url(_params);
        new Thread(new Runnable() {
            @Override
            public void run() {
                post(url, params, responseCallbackHandler);
            }
        }).start();
    }

map转换成string类型的url参数：

/**
     * map转url参数
     */
    public static String map2Url(Map<String, String> paramToMap) {
        if (null == paramToMap || paramToMap.isEmpty()) {
            return null;
        }
        StringBuffer url    = new StringBuffer();
        boolean      isfist = true;
        for (Map.Entry<String, String> entry : paramToMap.entrySet()) {
            if (isfist) {
                isfist = false;
            } else {
                url.append("&");
            }
            url.append(entry.getKey()).append("=");
            String value = entry.getValue();
            if (!TextUtils.isEmpty(value)) {
                try {
                    url.append(URLEncoder.encode(value, CHARSET_UTF8));
                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                }
            }
        }
        return url.toString();
    }

post执行：(注：这里简单的描述了下接口返回参数而已)。

/**
     * post请求
     */
    public static void post(String url, String params, ResponseCallbackHandler responseCallbackHandler) {
        StringBuffer bufferRes = null;
        try {
            HttpURLConnection http = initHttps(url, "POST", null);
            OutputStream out = http.getOutputStream();
            out.write(params.getBytes(CHARSET_UTF8));
            out.flush();
            out.close();

            InputStream in = http.getInputStream();
            BufferedReader read = new BufferedReader(new InputStreamReader(in, CHARSET_UTF8));
            String valueString = null;
            bufferRes = new StringBuffer();
            while ((valueString = read.readLine()) != null) {
                bufferRes.append(valueString);
            }
            in.close();
            if (http != null) {
                http.disconnect();// 关闭连接
            }
            if(responseCallbackHandler != null) {
                responseCallbackHandler.onSuccess(bufferRes.toString());
                LogUtils.d(tag, "onSuccess");
                LogUtils.d(tag, "onSuccess:" + bufferRes.toString());
            }
        } catch (Exception e) {
            e.printStackTrace();
            if (responseCallbackHandler != null) {
                responseCallbackHandler.onNetworkError();
            }
        }
        if (responseCallbackHandler != null) {
            responseCallbackHandler.onFinish();
        }
    }

实例化HttpURLConnection post请求时，ssl添加权限：

/**
     * 初始化http请求参数
     */
    private static HttpsURLConnection initHttps(String url, String method, Map<String, String> headers)
            throws IOException, NoSuchAlgorithmException, NoSuchProviderException, KeyManagementException {
        TrustManager[] tm = {new CustomX509TrustManager()};
        SSLContext     sslContext = SSLContext.getInstance("TLSv1");
        sslContext.init(null, tm, new java.security.SecureRandom());
        // 从上述SSLContext对象中得到SSLSocketFactory对象
        SSLSocketFactory ssf  = sslContext.getSocketFactory();
        URL              _url = new URL(url);
        HttpsURLConnection http = (HttpsURLConnection) _url.openConnection();
        // 连接超时
        http.setConnectTimeout(25000);
        // 读取超时 --服务器响应比较慢，增大时间
        http.setReadTimeout(25000);
        http.setRequestMethod(method);
        http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        http.setRequestProperty("User-Agent",
                "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36");
        if (null != headers && !headers.isEmpty()) {
            for (Map.Entry<String, String> entry : headers.entrySet()) {
                http.setRequestProperty(entry.getKey(), entry.getValue());
            }
        }
        http.setSSLSocketFactory(ssf);
        http.setDoOutput(true);
        http.setDoInput(true);
        http.connect();
        return http;
    }

添加证书管理：

// 证书管理
class CustomX509TrustManager implements X509TrustManager {

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }

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

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