问题描述
我正在尝试运行示例Java应用程序，
i am trying to run the sample java application as described on
我已经能够正确设置我的自由服务器，并且能够使用我的帐户在bluemix服务器上创建一个应用程序.当我尝试在Eclipse中运行示例代码时，我可以看到watson q& a应用程序界面.但是当我按下询问"按钮时，我得到了
i have been able to set up my liberty server properly and i have been able to create an app on the bluemix server with my account. When i try to run the sample code in Eclipse, i can see the watson q&a app interface. But when i hit the Ask button, i get
Error: Connect to gateway.watsonplatform.net:443 [gateway.watsonplatform.net/23.246.237.54] failed: Connection timed out: connect
除了输入服务网址和用户名和密码的值外，我没有对代码进行任何更改.
i have not made any changes to the code except putting in the values for the url of my service and the username and password.
我需要设置另一个系统属性吗?
Is there another system property i need to set?
manifest.yaml
applications:
- services:
- question_and_answer
name: myDumbApp
path: webApp.war
memory: 512M
另外，当我运行命令时
cf marketplace -s question_and_answer
我明白了
service plan description free or paid
question_and_answer_free_plan Beta free
那是正确的吗?
试用QuestionAndAnswer API
import java.util.HashMap;
import java.util.Map;
import com.ibm.watson.developer_cloud.personality_insights.v2.PersonalityInsights;
import com.ibm.watson.developer_cloud.personality_insights.v2.model.Profile;
import com.ibm.watson.developer_cloud.question_and_answer.*;
import com.ibm.watson.developer_cloud.question_and_answer.v1.QuestionAndAnswer;
import com.ibm.watson.developer_cloud.question_and_answer.v1.model.QuestionAndAnswerDataset;
public class PersonalityInsightsExample {
public static void main(String[] args) {
QuestionAndAnswer qas = new QuestionAndAnswer();
qas.setUsernameAndPassword("uName", "Pass");
QuestionAndAnswerDataset qd = new QuestionAndAnswerDataset("TRAVEL");
/*
PersonalityInsights service = new PersonalityInsights();
service.setUsernameAndPassword("uName", "Pass");
String myProfile = "Call me Ishmael. Some years ago-never mind how long "
+ "precisely-having little or no money in my purse, and nothing "
+ "particular to interest me on shore, I thought I would sail about "
+ "a little and see the watery part of the world. It is a way "
+ "I have of driving off the spleen and regulating the circulation. "
+ "Whenever I find myself growing grim about the mouth; whenever it "
+ "is a damp, drizzly November in my soul; whenever I find myself "
+ "involuntarily pausing before coffin warehouses, and bringing up "
+ "the rear of every funeral I meet; and especially whenever my "
+ "hypos get such an upper hand of me, that it requires a strong "
+ "moral principle to prevent me from deliberately stepping into "
+ "the street, and methodically knocking people's hats off-then, "
+ "I account it high time to get to sea as soon as I can.";
Profile profile = service.getProfile(myProfile);
*/
qas.setDataset(qd);
System.out.println( qas.ask("How to get cold?"));
}
}
但我仍然得到
SEVERE: IOException
org.apache.http.conn.HttpHostConnectException: Connection to https://gateway.watsonplatform.net refused
请注意，当我跑步
System.out.println(qas.getEndPoint());
我明白了
https://gateway.watsonplatform.net/question-and-answer-beta/api
这与我的代码中的导入一致吗?
is that consistent with the imports in my code?
推荐答案
确保您具有服务凭证，并且没有使用Bluemix username和password.
Make sure you have service credentials and you are not using your Bluemix username and password.
由于您要使用Personality-Insights，我建议您首先从Main类开始，然后尝试看看您是否具有有效的凭据
Since you want to use Personality-Insights I would suggest you to first start with a Main class and try to see that you have valid credentials
- Download the Watson Developer Cloud Java SDK v1.1.1.
- In eclipse, create a java project(no web, plain java).
- Create a file and call it
PersonalityInsightsExample.java. Copy the code below.
import java.util.HashMap; 导入java.util.Map; 导入com.ibm.watson.developer_cloud.personality_insights.v2.model.Profile;
import java.util.HashMap; import java.util.Map; import com.ibm.watson.developer_cloud.personality_insights.v2.model.Profile;
公共类PersonalityInsightsExample {
public class PersonalityInsightsExample {
public static void main(String[] args) {
PersonalityInsights service = new PersonalityInsights();
service.setUsernameAndPassword("<username>", "<password>");
String myProfile = "Call me Ishmael. Some years ago-never mind how long "
+ "precisely-having little or no money in my purse, and nothing "
+ "particular to interest me on shore, I thought I would sail about "
+ "a little and see the watery part of the world. It is a way "
+ "I have of driving off the spleen and regulating the circulation. "
+ "Whenever I find myself growing grim about the mouth; whenever it "
+ "is a damp, drizzly November in my soul; whenever I find myself "
+ "involuntarily pausing before coffin warehouses, and bringing up "
+ "the rear of every funeral I meet; and especially whenever my "
+ "hypos get such an upper hand of me, that it requires a strong "
+ "moral principle to prevent me from deliberately stepping into "
+ "the street, and methodically knocking people's hats off-then, "
+ "I account it high time to get to sea as soon as I can.";
Profile profile = service.getProfile(myProfile);
System.out.println(profile);
}
}
替换username和password.
作为Java应用程序运行.
Run it as a Java Application.
If you still get an error following the steps above then try opening a browser and going to: https://gateway.watsonplatform.net/personality-insights/api/v2/profile, you should get a password prompt.
