java http协议，添加header以及post传参，以及服务端获取

一、客户端请求

public static String test(){
    JSONObject obj = new JSONObject();
    obj.put("cusName","禹州林业集团");
    obj.put("socialCreditCode","11431000006542054G");
    String parm = obj.toString();
    String result = "";//BASE64加密的返回结果
    String res = "";//解密后的字符串
    PrintWriter out = null;
    BufferedReader in = null;
    try {
        java.net.URL realUrl;
        realUrl = new URL("http://127.0.0.1:9998/test/c/getC");
        HttpURLConnection conn = (HttpURLConnection) realUrl.openConnection();
        conn.setRequestMethod("POST");
        // 设置通用的请求属性
        conn.setRequestProperty("accept", "*/*");
        conn.setRequestProperty("connection", "Keep-Alive");
        conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
        conn.setRequestProperty("Content-Type", "text/plain;charset=utf-8");
        conn.addRequestProperty("token","11111");  //设置header信息
        // 发送POST请求必须设置如下两行
        conn.setDoOutput(true);
        conn.setDoInput(true);
        // 获取URLConnection对象对应的输出流
        out = new PrintWriter(conn.getOutputStream());
        // 发送请求参数
        out.print(parm);//json传参
        // flush输出流的缓冲
        out.flush();
        // 定义BufferedReader输入流来读取URL的响应
        in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = in.readLine()) != null) {
            result += line;
        }
        System.out.println(res);
        System.out.println(result);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {// 使用finally块来关闭输出流、输入流
        try {
            if (out != null) {
                out.close();
            }
            if (in != null) {
                in.close();
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
    return result;
}

 

 

 

二、服务端获取

@RequestMapping(value = "/c/getC",method=RequestMethod.POST)
public String getCustomerInfoForGGIP(HttpServletRequest request) throws Exception{
    String cusName = "";
    String socialCreditCode = "";
    String result = "";
    BASE64Encoder base64Encoder = new BASE64Encoder();
    JSONObject resultObject = new JSONObject();
    String token = request.getHeader("token");//获取header中内容
    if(StringUtils.isEmpty(token)){
        resultObject.put("code","1111");
        resultObject.put("msg","鉴权的token不能为空！");
        return resultObject.toString();
    }
    if(!"ZGCDB".equals(token)){
        resultObject.put("code","1111");
        resultObject.put("msg","鉴权不成功！");
        return resultObject.toString();
    }else{
        String parm = "";
        BufferedReader in = null;
        in = new BufferedReader(new InputStreamReader(request.getInputStream()));
        String line;
        while ((line = in.readLine()) != null) {   //获取参数
            parm += line;
        }
        if(parm!=null){
            JSONObject paramJson = JSONObject.fromObject(parm);
            if(!paramJson.isNullObject()){
                cusName = paramJson.getString("cusName");
                socialCreditCode = paramJson.getString("socialCreditCode");
                result = customerBo.getCustomerInfoForGGIP(cusName,socialCreditCode,request);
            }else{
                resultObject.put("code","1111");
                resultObject.put("msg","参数解析错误！");
                return resultObject.toString();
            }
        }else{
            resultObject.put("code","1111");
            resultObject.put("msg","参数解析错误！");
            return resultObject.toString();
        }
    }
    return result;
}
