Java HTTPS Client – HttpsURLConnection Example

Here’s a simple Java HTTPS client to demonstrate the use of HttpsURLConnection class to print a https URL content and certificate detail.

Access https URL : https://www.google.com/

package com.mkyong.client;
 
import java.net.MalformedURLException;
import java.net.URL;
import java.security.cert.Certificate;
import java.io.*;
 
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLPeerUnverifiedException;
 
public class HttpsClient{
 
   public static void main(String[] args)
   {
        new HttpsClient().testIt();
   }
 
   private void testIt(){
 
      String https_url = "https://www.google.com/";
      URL url;
      try {
 
	     url = new URL(https_url);
	     HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
 
	     //dumpl all cert info
	     print_https_cert(con);
 
	     //dump all the content
	     print_content(con);
 
      } catch (MalformedURLException e) {
	     e.printStackTrace();
      } catch (IOException e) {
	     e.printStackTrace();
      }
 
   }
 
   private void print_https_cert(HttpsURLConnection con){
 
    if(con!=null){
 
      try {
 
	System.out.println("Response Code : " + con.getResponseCode());
	System.out.println("Cipher Suite : " + con.getCipherSuite());
	System.out.println("\n");
 
	Certificate[] certs = con.getServerCertificates();
	for(Certificate cert : certs){
	   System.out.println("Cert Type : " + cert.getType());
	   System.out.println("Cert Hash Code : " + cert.hashCode());
	   System.out.println("Cert Public Key Algorithm : " + cert.getPublicKey().getAlgorithm());
	   System.out.println("Cert Public Key Format : " + cert.getPublicKey().getFormat());
	   System.out.println("\n");
	}
 
	} catch (SSLPeerUnverifiedException e) {
		e.printStackTrace();
	} catch (IOException e){
		e.printStackTrace();
	}
 
     }
 
   }
 
   private void print_content(HttpsURLConnection con){
	if(con!=null){
 
	try {
 
	   System.out.println("****** Content of the URL ********");			
	   BufferedReader br = 
		new BufferedReader(
			new InputStreamReader(con.getInputStream()));
 
	   String input;
 
	   while ((input = br.readLine()) != null){
	      System.out.println(input);
	   }
	   br.close();
 
	} catch (IOException e) {
	   e.printStackTrace();
	}
 
       }
 
   }
 
}

Output…

Response Code : 200
Cipher Suite : SSL_RSA_WITH_RC4_128_SHA
 
Cert Type : X.509
Cert Hash Code : 7810131
Cert Public Key Algorithm : RSA
Cert Public Key Format : X.509
 
Cert Type : X.509
Cert Hash Code : 6042770
Cert Public Key Algorithm : RSA
Cert Public Key Format : X.509
 
****** Content of the URL ********
<!doctype html><html><head><meta http-equiv="content-type" ......

[轉(zhuǎn)載] JDom輸出UTF-8的XML出現(xiàn)中文亂碼完美解決

完美的解決方法從辟謠開始：
1）JDOM是否生成UTF-8的文件與Format是否設(shè)置無關(guān)，只有輸出其他字符編碼才需要設(shè)置，見下面的注釋。
2）JDOM輸出UTF-8文件亂碼的根本原因并非在JDOMAPI，而是在JDK。
具體描述：
    JDOM的輸出類XMLOutputter有兩個(gè)output接口，除了都具有一個(gè)Document參數(shù)外，分別接受Writer和 OutputStream參數(shù)。
    這給我們一個(gè)錯覺，兩個(gè)接口可以任意使用。
    首先我們用output(doc,System.out)來做測試，此時(shí)得到亂碼，
      然后我們改為output(doc,new PrintWriter(System.out))來測試，輸出不是亂碼，
      也就是說在控制臺的時(shí)候一定要用一個(gè)Writer接口包裝一下。
     然后我們用output(doc,new FileWriter(path))來做測試，結(jié)果卻得到亂碼，
      然后我們改為output(doc,new FileOutputStream(path))來測試，輸出不是亂碼，
      也就是說在輸出文件的時(shí)候一定要用一個(gè)OutputStream接口包裝一下。
     瘋了吧？呵呵，很搞笑是吧。經(jīng)過到JDOM的源碼中調(diào)試，發(fā)現(xiàn)沒有任何問題，問題出在了JDK里面。
JDK內(nèi)的對應(yīng)接口處理：
1）PrintWriter類有參數(shù)為OutputStream的構(gòu)造方法，因此可以從System.out包裝到PrintWriter
2）FileWriter類沒有參數(shù)為OutputStream的構(gòu)造方法，因此不能從FileOutputStream包裝到 FileWriter
3）如果PrintWriter類用了參數(shù)為Writer的構(gòu)造方法（Writer實(shí)現(xiàn)為FileWriter），最后輸出也是亂碼
4）如果用一個(gè)FileOutputStream來包裝一個(gè)控制臺輸出，也是亂碼
因此，對于JDK內(nèi)的各種輸出體系，各種InputStream、OutputStream、reader和writer要充分認(rèn)識，否則極容易出現(xiàn)一些意想不到的問題。

我的第一個(gè)oracle trigger

//建表：
-- Create table
create table EMP
(
ID         NUMBER,
ENAME      VARCHAR2(50),
EMPNO      VARCHAR2(50),
SALARY     NUMBER(10),
DEPTNO     VARCHAR2(50),
CREATETIME DATE default sysdate
)
tablespace USERS
pctfree 10
initrans 1
maxtrans 255
storage
(
    initial 64K
    minextents 1
    maxextents unlimited
);

建立歷史表：
create table emp_his as select * from emp where 1=2

建立oracle觸發(fā)器：
create or replace trigger tri_del_emp
before delete on emp
for each row
begin
insert into emp_his(id,ename,empno,salary,deptno,createtime) values
(:old.id,:old.ename,:old.empno,:old.salary,:old.deptno,:old.createtime);
end;

執(zhí)行測試操作：
delete emp where id=8

這個(gè)時(shí)候，歷史表，信息已經(jīng)插入進(jìn)去了，呵呵

oracle function異常

建立異常表：

-- Create table
create table ORACLEEXCEPTION
(
  ID          VARCHAR2(36),
  CREATETIME  DATE,
  SQLCODE1    NVARCHAR2(300),
  SQLERRM1    NVARCHAR2(300),
  MYEXCEPTION NVARCHAR2(100)
)
tablespace USERS
  pctfree 10
  initrans 1
  maxtrans 255
  storage
  (
    initial 64K
    minextents 1
    maxextents unlimited
  );

編寫oracle--function：

create or replace function getabin(abin in varchar2)
return varchar2
is
result varchar2(50);
sqlcode2 nvarchar2(500):='';
sqlerrm2 nvarchar2(500):='';
myexception nvarchar2(500):='';
exception1 exception;
begin
if(abin is not null) then
select count(1) into result from bing1 t where t.name1 like abin;
return(result);
elsif(abin is null) then
result:='there is a defined exception';
raise exception1;
end if;

exception
when exception1 then
sqlcode2:=sqlcode;
sqlerrm2:=sqlerrm;
begin
insert into oracleexception(id,createtime,sqlcode1,sqlerrm1,myexception) values (sys_guid(),sysdate,sqlcode2,sqlerrm2,'exception1');
commit;
end;
return(result);
when others then
result:='there is a other exception';
sqlcode2:=sqlcode;
sqlerrm2:=sqlerrm;
begin
insert into oracleexception(id,createtime,sqlcode1,sqlerrm1,myexception) values (sys_guid(),sysdate,sqlcode2,sqlerrm2,'others');
commit;
end;
return(result);
end;

測試oracle--function代碼：

declare
ename varchar2(50):='';
result varchar2(50);
begin
result:=getabin(ename);
dbms_output.put_line(result);
end;

我寫的oracle function

oracle函數(shù)一：
create or replace function getBin
return varchar2
is
result varchar2(50);
begin
select count(1) into result from bing1;
return(result);
end;

測試代碼：
declare
result varchar2(50);
begin
result:=getBin;
dbms_output.put_line(result);
end;

oracle函數(shù)二：
create or replace function getBin3(ename in varchar2)
return varchar2
is
result varchar(50);
begin
select count(1) into result from bing1 t where t.name1 like '%'||ename||'%';
return(result);
end;

測試代碼二：
declare
result varchar2(50);
ename varchar2(10):='a';
begin
result:=getBin3(ename);
dbms_output.put_line(result);
end;

oracle function用法

函數(shù)調(diào)用限制
1、SQL語句中只能調(diào)用存儲函數(shù)(服務(wù)器端),而不能調(diào)用客戶端的函數(shù)
2、SQL只能調(diào)用帶有輸入?yún)?shù),不能帶有輸出,輸入輸出函數(shù)
3、SQL不能使用PL/SQL的特有數(shù)據(jù)類型(boolean,table,record等)
4、SQL語句中調(diào)用的函數(shù)不能包含INSERT,UPDATE和DELETE語句

1.function函數(shù)的語法如下：

create or replace function function_name (

argu1 [mode1] datatype1, --定義參數(shù)變量

argu2 [mode2] datatype2 --定義參數(shù)變量

) return datatype --定義返回的數(shù)據(jù)類型

begin

end;

執(zhí)行 var v1 varchar2(100)
exec :v1:=function_name

2.不帶任何參數(shù)的定義

create or replace function get_user

return varchar2

Result varchar2(50); --定義變量

begin

select username into Result from user_users;

return(Result); --返回值

end get_user;

3.帶有in參數(shù)的

create or replace function get_sal(

empname in varchar2

) return number

Result number;

begin

select sal into Result from emp where ename=empname;

return(Result);

end;

執(zhí)行: SQL> var sal number
SQL> exec :sal:=get_sal('scott');

4.帶out參數(shù)的

create or replace function get_info(

e_name varchar2,

job out varchar2

) return number

Result number;

begin

select sal,job into Result,job from emp where ename=e_name;
return(Result);
end;

執(zhí)行: SQL> var job varchar2(20)
SQL> var dname varchar2(20)
SQL> exec :dname:=get_info('SCOTT',:job)

5.帶in out參數(shù)的

6.函數(shù)調(diào)用舉例

create or replace function f_sys_getseqid(
    v_seqname           IN VARCHAR2,
    v_provincecode      IN VARCHAR2    --省編碼
) return Varchar2
IS
    iv_date             VARCHAR2(8);
    iv_seqname          VARCHAR2(50);
    iv_sqlstr           VARCHAR2(200);
    iv_seq              VARCHAR2(8);
    iv_seqid            VARCHAR2(16);
BEGIN
    iv_seqname := LOWER(TRIM(v_seqname));
    iv_sqlstr := 'SELECT '||iv_seqname||'.nextval FROM DUAL';
    EXECUTE IMMEDIATE iv_sqlstr INTO iv_seq;--執(zhí)行動態(tài)的sql語句，執(zhí)行相似的一組語句
    IF v_seqname = 'SEQ_FUNCROLE_ID' THEN
      iv_seqid:= 'ESS' || LPAD(iv_seq,5,'0');
    ELSE
      SELECT substrb(v_provincecode,1,2)||TO_CHAR(SYSDATE,'yymmdd') INTO iv_date FROM DUAL;
      iv_seqid:= iv_date || LPAD(iv_seq,8,'0');
    END IF;
    RETURN iv_seqid;
EXCEPTION
    WHEN OTHERS THEN
    RETURN NULL;
END;

調(diào)用方式如下：

SELECT TO_NUMBER(F_SYS_GETSEQID('SEQ_TERMTRADE_ID', V_PROVINCE_CODE)) INTO V_BATCH_ID FROM DUAL;

EXECUTE IMMEDIATE的說明：執(zhí)行動態(tài)的sql語句。
