HTTP Client 调用 ODI Scenario

HTTP-Client的官方实例如下：

http://svn.apache.org/viewvc/httpcomponents/oac.hc3x/trunk/src/examples/FormLoginDemo.java?revision=604567&view=markup

ODI官方文档中推荐HTTP URL方式调用Scenario

部分描述：

With the Metadata Navigator module, it is possible to launch a scenario from a web page or an
HTTP URL.
Note: To execute a scenario this way, you must first Install Metadata Navigator.
Principles
Metadata Navigator provides a StartScen servlet that responds to HTTP POST requests. This
servlet provides the same features as the OdiStartScen tool.
 The StartScen servlet is called by using an HTTP POST request on the /snpsrepexp/startscen.do resource of your Metadata Navigator Server. Appropriate

HTTP parameters should be passed with the request.
 The servlet returns an HTTP response in XML, HTML or plain text format.

The scenario execution returns a SOAP response as shown below:
<odi:invokeScenarioResponse xmlns:odi="xmlns.oracle.com/odi/OdiInvoke">
<odi:CommandResultType>
<odi:Ok>true</odi:Ok>
<odi:SessionNumber>1148001</odi:SessionNumber>
</odi:CommandResultType>
</odi:invokeScenarioResponse>

1、安装Metadata Navigator（参考Metadata Navigator安装及应用）

2、配置ODI Agent（参考ODI Scenario Scheduler Agent执行中的Agent配置文件设置->odiparams.bat设置）非必须

3、在ODI项目中创建Scenario（参考Running Scenario Using Variable）

4、创建JAVA应用

注：若oracledimn.war部署在远程服务器上，则

LOGON_SIT 与 LOGON_PORT需要改成对应的 IP 与 端口号

NameValuePair agentName = new NameValuePair("agent_name", "127.0.0.1");需要改成Agent所在机器的IP<如10.243.40.72>

创建ODIHttpWebService.java

import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.cookie.CookiePolicy;
import org.apache.commons.httpclient.cookie.CookieSpec;
import org.apache.commons.httpclient.methods.*;

public class ODIHttpWebservice {
static final String LOGON_SITE = "localhost";
static final int LOGON_PORT = 9090;
public ODIHttpWebservice() {
super();
}

public static void main(String[] args) throws Exception {
HttpClient client = new HttpClient();
client.getHostConfiguration().setHost(LOGON_SITE, LOGON_PORT, "http");
client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
CookieSpec cookiespec = CookiePolicy.getDefaultSpec();
PostMethod authpost = new PostMethod("/oracledimn/startscen.do");

// Prepare execute parameters(参数设置参照Oracle Data Integrator User's Guide/86)

NameValuePair agentName = new NameValuePair("agent_name", "127.0.0.1");
NameValuePair agentPort = new NameValuePair("agent_port", "20910");
NameValuePair masterDriver = new NameValuePair("master_driver","oracle.jdbc.driver.OracleDriver");
NameValuePair masterUrl = new NameValuePair("master_url", "jdbc:oracle:thin:@10.244.155.16:1521:ora10g");
NameValuePair masterUser = new NameValuePair("master_user", "EXTFWK");
NameValuePair masterPsw = new NameValuePair("master_psw", "cByXdik4DDOzPIqHygsc5Wp");
NameValuePair workRepository = new NameValuePair("work_repository", "EASAS WORK01");
NameValuePair snpsUser = new NameValuePair("snps_user", "SUPERVISOR");
NameValuePair snpsPsw = new NameValuePair("snps_psw", "fDyXwp0FX38Lh7SljxUs");
NameValuePair scenName = new NameValuePair("scen_name", "LOAD_ROLE_FUNCTIONS");
NameValuePair scenVersion = new NameValuePair("scen_version", "001");
NameValuePair contextCode = new NameValuePair("context_code", "GLOBAL");
NameValuePair logLevel = new NameValuePair("log_level", "2");
NameValuePair httpReply = new NameValuePair("http_reply", "XML");

//Add Project's Variable by using project code
NameValuePair projectParam1 = new NameValuePair("EASAS_PROJECT.roleCode", "'USER_MANAGE'");

authpost.setRequestBody(
new NameValuePair[] { agentName, agentPort, masterDriver, masterUrl,
masterUser, masterPsw, workRepository, snpsUser, snpsPsw, scenName,
scenVersion, contextCode, logLevel, httpReply, projectParam1});

client.executeMethod(authpost);
System.out.println("Project Param1: "+projectParam1.getValue()+" \nLogin form post: " + authpost.getResponseBodyAsString().toString());

// release any connection resources used by the method

authpost.releaseConnection();

}
}

5、启动Tomcat，确认Metadata Navigator应用正常

6、调用ODIAgent，确认Agent正常使用

7、运行JAVA应用，执行正常将在控制台得到输出信息，输出信息类似以下结构：

<odi:invokeScenarioResponse xmlns:odi="xmlns.oracle.com/odi/OdiInvoke">
<odi:CommandResultType>
<odi:Ok>true</odi:Ok>
<odi:SessionNumber>1148001</odi:SessionNumber>
</odi:CommandResultType>
</odi:invokeScenarioResponse>

8、到ODI中检查会话是否正常执行，检查参数传递是否生效
