Oracle使用JAVA发送HTTP请求

create or replace and compile java source named pushmessage as
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class PushMessage
{
public static String sendGet(String url, String param) {
String result = "";
BufferedReader in = null;
try {
String urlNameString = url;
if(param!=null){
urlNameString+="?"+param;
}
URL realUrl = new URL(urlNameString);
// 打开和URL之间的连接
URLConnection connection = realUrl.openConnection();
// 设置通用的请求属性
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("connection", "Keep-Alive");
connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
connection.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
connection.setConnectTimeout(10000);
connection.setReadTimeout(10000);
// 建立实际的连接
connection.connect();
// 定义 BufferedReader输入流来读取URL的响应
in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (IOException e) {
e.printStackTrace();
}
// 使用finally块来关闭输入流
finally {
try {
if (in != null) {
in.close();
}
} catch (Exception e2) {
e2.printStackTrace();
}
}
return result;
}
}

create or replace procedure pushMessage(url varchar2,params varchar2)
as language java name
'PushMessage.sendGet(java.lang.String,java.lang.String)';
