java http協議，添加header以及post傳參，以及服務端獲取

一、客戶端請求

public static String test(){
JSONObject obj = new JSONObject();
obj.put("cusName","禹州林業集團");
obj.put("socialCreditCode","11431000006542054G");
String parm = obj.toString();
String result = "";//BASE64加密的返回結果
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");
// 設置通用的請求屬性
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"); //設置header信息
// 發送POST請求必須設置如下兩行
conn.setDoOutput(true);
conn.setDoInput(true);
// 獲取URLConnection對象對應的輸出流
out = new PrintWriter(conn.getOutputStream());
// 發送請求參數
out.print(parm);//json傳參
// flush輸出流的緩沖
out.flush();
// 定義BufferedReader輸入流來讀取URL的響應
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塊來關閉輸出流、輸入流
try {
if (out != null) {
out.close();
}
if (in != null) {
in.close();
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
return result;
}

 

 

二、服務端獲取

@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");//獲取header中內容
if(StringUtils.isEmpty(token)){
resultObject.put("code","1111");
resultObject.put("msg","鑒權的token不能為空！");
return resultObject.toString();
}
if(!"ZGCDB".equals(token)){
resultObject.put("code","1111");
resultObject.put("msg","鑒權不成功！");
return resultObject.toString();
}else{
String parm = "";
BufferedReader in = null;
in = new BufferedReader(new InputStreamReader(request.getInputStream()));
String line;
while ((line = in.readLine()) != null) { //獲取參數
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","參數解析錯誤！");
return resultObject.toString();
}
}else{
resultObject.put("code","1111");
resultObject.put("msg","參數解析錯誤！");
return resultObject.toString();
}
}
return result;
}
