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;
}
