Java获取Token，含Authorization参数以及body参数
代码如下：
public String getAccesstoken () { String result = null; //请求地址 Properties pro = getProperties(); String url = pro.getProperty("getToken"); String responseInfo = ""; String appId= ""; String appSecret = ""; //body中的参数 String grant_type = ""; String scope=""; //参数设置 List<NameValuePair> parameForToken = new ArrayList<NameValuePair>(); parameForToken.add(new BasicNameValuePair("grant_type", grant_type)); parameForToken.add(new BasicNameValuePair("scope", scope));//使用base64进行加密 byte[] tokenByte = Base64.encodeBase64((appId+":"+appSecret).getBytes()); //将加密的信息转换为string String tokenStr = Base.bytesSub2String(tokenByte, 0, tokenByte.length); //Basic YFUDIBGDJHFK78HFJDHF== token的格式 String token = "Basic "+tokenStr; // 获取httpclient CloseableHttpClient httpclient = HttpClients.createDefault(); CloseableHttpResponse response = null; try { //创建post请求 HttpPost httpPost = new HttpPost(url); //PostMethod pMethod = new PostMethod(url); // 设置请求和传输超时时间 RequestConfig requestConfig = RequestConfig.custom() .setSocketTimeout(20000).setConnectTimeout(20000).build(); httpPost.setConfig(requestConfig); // 提交参数发送请求 UrlEncodedFormEntity urlEncodedFormEntity = new UrlEncodedFormEntity(parameForToken); httpPost.setEntity(urlEncodedFormEntity); //把认证信息发到header中 httpPost.setHeader("Authorization",token); response = httpclient.execute(httpPost); // 得到响应信息 int statusCode = response.getStatusLine().getStatusCode(); // 判断响应信息是否正确 if (statusCode != HttpStatus.SC_OK) { // 终止并抛出异常 httpPost.abort(); throw new RuntimeException("HttpClient,error status code :" + statusCode); } HttpEntity entity = response.getEntity(); if (entity != null) { //result = EntityUtils.toString(entity);//不进行编码设置 result = EntityUtils.toString(entity, "UTF-8"); } EntityUtils.consume(entity); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { //关闭所有资源连接 if (response != null) { try { response.close(); } catch (IOException e) { e.printStackTrace(); } } if (httpclient != null) { try { httpclient.close(); } catch (IOException e) { e.printStackTrace(); } } } System.out.println(result); return result; }

getProperties()方法：
public Properties getProperties() {
InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("resources/constant.properties");
Properties p = new Properties();
try {
p.load(inputStream);
} catch (IOException e1) {
System.out.println("读取constant.properties文件失败"+ e1);
e1.printStackTrace();
}
return p;

Base.java中的bytesSub2String()方法：
/*** * @input src 待截取字节数组 * start 待截取字节数组的开始位置 * src_size 截取的长度 == 数据类型的长度 * * @output String 字节截取转换成String后的结果 * * **/ public static String bytesSub2String(byte[] src,int start,int src_size) { byte[] resBytes = new byte[src_size]; System.arraycopy(src, start, resBytes, 0, src_size); // System.out.println(" len ==" +resBytes.length // + " sub_bytes = " + bytes2Int1(resBytes)); return bytes2String(resBytes); }// byte[] --> String public static String bytes2String(byte b[]){ String result_str = new String(b); return result_str; }

常量全在constant.properties中写着。接下来一般都是把这个写入定时任务中，因为token一般都有有效时间，过了有效时间需要重新申请。所以写入定时任务中，让定时任务执行并获取token。
