(Don't include 183 | the brackets!) The text should be enclosed in the appropriate 184 | comment syntax for the file format. We also recommend that a 185 | file or class name and description of purpose be included on the 186 | same "printed page" as the copyright notice for easier 187 | identification within third-party archives. 188 | 189 | Copyright 2017 Intuit, Inc. 190 | 191 | Licensed under the Apache License, Version 2.0 (the "License"); 192 | you may not use this file except in compliance with the License. 193 | You may obtain a copy of the License at 194 | 195 | http://www.apache.org/licenses/LICENSE-2.0 196 | 197 | Unless required by applicable law or agreed to in writing, software 198 | distributed under the License is distributed on an "AS IS" BASIS, 199 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 200 | See the License for the specific language governing permissions and 201 | limitations under the License. 202 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | [![Rate your Sample](views/Ratesample.png)][ss1][![Yes](views/Thumbup.png)][ss2][![No](views/Thumbdown.png)][ss3] 2 | 3 | # OAuth2 - Java Sample App 4 | 5 | The [Intuit Developer team](https://developer.intuit.com) has written this OAuth 2.0 Sample App in Java to provide working examples of OAuth 2.0 concepts, and how to integrate with Intuit endpoints. 6 | 7 | ## Table of Contents 8 | 9 | * [Requirements](#requirements) 10 | * [First Use Instructions](#first-use-instructions) 11 | * [Running the code](#running-the-code) 12 | * [Configuring the callback endpoint](#configuring-the-callback-endpoint) 13 | * [Getting the OAuth Tokens](#getting-the-oauth-tokens) 14 | * [Scope](#scope) 15 | * [Storing the Tokens](#storing-the-tokens) 16 | * [Discovery document](#discovery-document) 17 | 18 | 19 | ## Requirements 20 | 21 | In order to successfully run this sample app you need a few things: 22 | 23 | 1. Java 1.8 24 | 2. A [developer.intuit.com](http://developer.intuit.com) account 25 | 3. An app on [developer.intuit.com](http://developer.intuit.com) and the associated client id and client secret. 26 | 27 | ## First Use Instructions 28 | 29 | 1. Clone the GitHub repo to your computer 30 | 2. Fill in the [`application.properties`](src/main/resources/application.properties) file values (OAuth2AppClientId, OAuth2AppClientSecret) by copying over from the keys section for your app. 31 | 32 | ## Running the code 33 | 34 | Once the sample app code is on your computer, you can do the following steps to run the app: 35 | 36 | 1. cd to the project directory 37 | 2. Run the command:`./gradlew bootRun` (Mac OS) or `gradlew.bat bootRun` (Windows) 38 | 3. Wait until the terminal output displays the "Started Application in xxx seconds" message. 39 | 4. Your app should be up now in http://localhost:8080/ 40 | 5. The oauth2 callback endpoint in the sample app is http://localhost:8080/oauth2redirect 41 | 6. To run the code on a different port, uncomment and update server.port property in application.properties 42 | 43 | ## Configuring the callback endpoint 44 | You'll have to set a Redirect URI in the Developer Portal ("Keys" section). With this app, the typical value would be http://localhost:8080/oauth2redirect, unless you host this sample app in a different way (if you were testing HTTPS, for example). 45 | 46 | Note: Using localhost and http will only work when developing, using the sandbox credentials. Once you use production credentials, you'll need to host your app over https. 47 | 48 | ## Getting the OAuth Tokens 49 | 50 | The sample app supports the following flows: 51 | 52 | **Sign In With Intuit** - this flow requests OpenID only scopes. Feel free to change the scopes being requested in `application.properties`. After authorizing (or if the account you are using has already been authorized for this app), the redirect URL (`/oauth2redirect`) will parse the JWT ID token, and make an API call to the user information endpoint. 53 | 54 | **Connect To QuickBooks** - this flow requests non-OpenID scopes. You will be able to make a QuickBooks API sample call (using the OAuth2 token) on the `/connected` landing page. Sample implementation for RefreshToken and RevokeToken is also available in that page. 55 | 56 | **Get App Now (Connect Handler)** - this flow requests both OpenID and non-OpenID scopes. It simulates the request that would come once a user clicks "Get App Now" on the [apps.com](https://apps.com) website, after you publish your app. 57 | 58 | ## Scope 59 | 60 | It is important to ensure that the scopes your are requesting match the scopes allowed on the Developer Portal. For this sample app to work by default, your app on Developer Portal must support Accounting scopes. If you'd like to support both Accounting and Payment, simply add the`com.intuit.quickbooks.payment` scope in the `application.properties` file. 61 | 62 | ## Storing the tokens 63 | This app stores all the tokens and user information in the session. For production ready app, tokens should be encrypted and stored in a database. 64 | 65 | ## Discovery document 66 | The app calls the discovery API during starup and loads all the endpoint urls. For production ready app, make sure to run this API once a day to get the latest urls. 67 | 68 | [ss1]: # 69 | [ss2]: https://customersurveys.intuit.com/jfe/form/SV_9LWgJBcyy3NAwHc?check=Yes&checkpoint=OAuth2-Java&pageUrl=github 70 | [ss3]: https://customersurveys.intuit.com/jfe/form/SV_9LWgJBcyy3NAwHc?check=No&checkpoint=OAuth2-Java&pageUrl=github 71 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | 2 | buildscript { 3 | repositories { 4 | mavenCentral() 5 | } 6 | dependencies { 7 | classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.0.RELEASE") 8 | } 9 | } 10 | 11 | apply plugin: 'java' 12 | apply plugin: 'eclipse' 13 | apply plugin: 'idea' 14 | apply plugin: 'org.springframework.boot' 15 | apply plugin: 'io.spring.dependency-management' 16 | 17 | jar { 18 | baseName = 'auth2-java' 19 | version = '0.1.0' 20 | } 21 | 22 | repositories { 23 | mavenCentral() 24 | } 25 | 26 | sourceCompatibility = 1.8 27 | targetCompatibility = 1.8 28 | 29 | dependencies { 30 | compile("org.springframework.boot:spring-boot-starter-web") 31 | compile("org.springframework.boot:spring-boot-starter-thymeleaf") 32 | compile("org.springframework.boot:spring-boot-devtools") 33 | compile('org.codehaus.jackson:jackson-core-asl:1.9.13') 34 | compile('org.codehaus.jackson:jackson-mapper-asl:1.9.13') 35 | compile("org.springframework.data:spring-data-rest-webmvc") 36 | compile("org.springframework:spring-test:4.1.4.RELEASE") 37 | compile("commons-lang:commons-lang:2.6") 38 | compile("org.apache.httpcomponents:httpcore") 39 | compile("org.apache.httpcomponents:httpclient") 40 | compile("log4j:log4j:1.2.17") 41 | compile (group: 'ant', name: 'ant', version: '1.7.0') 42 | compile group: 'org.json', name: 'json', version: '20180813' 43 | testCompile('org.springframework.boot:spring-boot-starter-test') 44 | 45 | } 46 | 47 | wrapper { 48 | gradleVersion = '2.3' 49 | } -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/IntuitDeveloper/OAuth2-Java/b5ae823011293287236178de211f73204850204d/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | #Tue Nov 15 10:38:19 PST 2016 2 | distributionBase=GRADLE_USER_HOME 3 | distributionPath=wrapper/dists 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists 6 | distributionUrl=https\://services.gradle.org/distributions/gradle-5.2.1-bin.zip 7 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bash 2 | 3 | ############################################################################## 4 | ## 5 | ## Gradle start up script for UN*X 6 | ## 7 | ############################################################################## 8 | 9 | # Add default JVM options here.
