4 1 Java SDK 1 Java SDK 1.1 Quick Start Environment Preparation 1. Obtain the API-related documents. For details about Application Programming Interface (APIs), see the API Reference. Access the Products with Open APIs page on HUAWEI CLOUD to obtain API references of other cloud services. 2. Enable the service: Log in to the Management Console, select a sub-service, and click Enable Service on the right. You only need to enable the service once. 3. Obtain the AK/SK of your HUAWEI CLOUD account. If no AK/SK has been generated, log in to HUAWEI CLOUD, enter the My Credential page, and choose Access Keys > Add Access Key to obtain the access keys. 4. Install the JDK. The Java SDK can run on JDK1.8 or later. SDK Acquisition and Installation Take Eclipse as an example. After creating a Java project, perform the following steps to import the JAR file to the new project: 1. Download the SDK JAR file from the following URL: target/frs-sdk-1.0-jar-with-dependencies.jar 2. Copy the downloaded JAR file to the project folder. 3. Open the project in Eclipse, right-click the project, and choose Properties. 4. In the displayed dialog box, click Java Build Path. On the Libraries tab, click Add JARs to add the downloaded JAR file. 5. Click OK. Services involved in this document use the same JAR file. Issue 02 ( ) Copyright Huawei Technologies Co., Ltd. 1
