Android 应用程序示例的 Watson Personality Insights 服务

Question

我想使用 IBM 的 Personality Insights Service。我已经下载了 Hello Wold 示例代码并尝试在其中集成 Personality Insights Service。

我的代码如下。

MainActivity.java

package com.ibm.bms.samples.android.helloworld;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;

import com.ibm.mobilefirstplatform.clientsdk.android.core.api.BMSClient;
import com.ibm.mobilefirstplatform.clientsdk.android.core.api.Request;
import com.ibm.mobilefirstplatform.clientsdk.android.core.api.Response;
import com.ibm.mobilefirstplatform.clientsdk.android.core.api.ResponseListener;
import com.ibm.watson.developer_cloud.personality_insights.v2.PersonalityInsights;
import com.ibm.watson.developer_cloud.personality_insights.v2.model.Profile;

import org.json.JSONObject;

import java.io.PrintWriter;
import java.io.StringWriter;
import java.net.MalformedURLException;
import java.net.UnknownHostException;

public class MainActivity extends Activity implements ResponseListener {

    private static final String TAG = MainActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView buttonText = (TextView) findViewById(R.id.button_text);

        try {
            //initialize SDK with IBM Bluemix application ID and route
            //TODO: Please replace <APPLICATION_ROUTE> with a valid ApplicationRoute and <APPLICATION_ID> with a valid ApplicationId
            BMSClient.getInstance().initialize(this, "http://bluemixpersonality.mybluemix.net", "b8c06c80-83fa-4448-b770-3ff5b3f1fb84");
        } catch (MalformedURLException mue) {
            this.setStatus("Unable to parse Application Route URL\n Please verify you have entered your Application Route and Id correctly and rebuild the app", false);
            buttonText.setClickable(false);
        }
    }

    public void pingBluemix(View view) {

        TextView buttonText = (TextView) findViewById(R.id.button_text);
        buttonText.setClickable(false);

        TextView errorText = (TextView) findViewById(R.id.error_text);
        errorText.setText("Pinging Bluemix");

        Log.i(TAG, "Pinging Bluemix");

        // Testing the connection to Bluemix by sending a Get request to the Node.js application, using this Activity to handle the response.
        // This Node.js code was provided in the MobileFirst Services Starter boilerplate.
        // The below request uses the IBM Mobile First Core sdk to send the request using the applicationRoute that was provided when initializing the BMSClient earlier.
        new Request(BMSClient.getInstance().getBluemixAppRoute(), Request.GET).send(this.getApplicationContext(), this);
    }

    private void setStatus(final String messageText, boolean wasSuccessful) {
        final TextView errorText = (TextView) findViewById(R.id.error_text);
        final TextView topText = (TextView) findViewById(R.id.top_text);
        final TextView bottomText = (TextView) findViewById(R.id.bottom_text);
        final TextView buttonText = (TextView) findViewById(R.id.button_text);
        final String topStatus = wasSuccessful ? "Yay!" : "Bummer";
        final String bottomStatus = wasSuccessful ? "You Are Connected" : "Something Went Wrong";

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                buttonText.setClickable(true);
                errorText.setText(messageText);
                topText.setText(topStatus);
                bottomText.setText(bottomStatus);
            }
        });
    }

    // Implemented for the response listener to handle the success response when Bluemix is pinged
    @Override
    public void onSuccess(Response response) {

        Log.e("Response: ", response.getResponseText());

        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.";

        PersonalityInsights service = new PersonalityInsights();
        service.setUsernameAndPassword("{username}","{password}");

        Profile personalityProfile = service.getProfile(myProfile);
        Log.e("hahah: ", "" + personalityProfile);

        setStatus("", true);
        Log.i(TAG, "Successfully pinged Bluemix!");
    }

    // Implemented for the response listener to handle failure response when Bluemix is pinged
    @Override
    public void onFailure(Response response, Throwable throwable, JSONObject jsonObject) {
        // Blah Blah Code on Failing to connect to IBM.
    }
}

build.gradle

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "com.ibm.bms.samples.android.helloworld"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.0'

            transitive: true
    compile 'com.ibm.watson.developer_cloud:java-wrapper:1.0.3'
}

How to call Watson Insights Service using java

我遇到以下错误。

Error Image

注意：我已经为 Personality Insights 服务设置了正确的用户名和密码。

Answer 1

看起来您正在使用 java-wrapper:1.0.3。那已经很老了，自该版本发布以来，我们对库进行了很多修复和改进。 401 表示您没有提供正确的凭据或服务 URL 不正确。您可以通过调用 service.setEndPoint()

来设置服务 URL

参见下面的示例：

将 gradle 中的依赖项更新为：

'com.ibm.watson.developer_cloud:java-sdk:5.3.0'

然后使用此代码：

PersonalityInsights service = new PersonalityInsights();
service.setUsernameAndPassword("<username>", "<password>");
service.setEndPoint("https://gateway.watsonplatform.net/personality-insights/api")

String text = "your text goes here...."
ProfileOptions options = new ProfileOptions.Builder()
  .text(text)
  .build();

Profile profile = service.profile(options).execute();
System.out.println(profile);

确保您拥有 Personality Insights 服务（tiered 计划）的凭据。如果您需要帮助，请查看此 guide.
最后，您的服务凭证 不是 您的 Bluemix 凭证。
