API签名指南签名SDK与demo

请求签名与API调用

在Android工程中的“app/libs”目录下，加入SDK所需jar包。其中jar包必须包括：
- java-sdk-core-x.x.x.jar
- commons-logging-1.2.jar
- joda-time-2.9.9.jar

在“build.gradle”文件中加入okhttp库的依赖。

在“build.gradle”文件中的“dependencies”下加入“implementation 'com.squareup.okhttp3:okhttp:3.11.0'”。

     
          dependencies {    
    ...
    ...
    implementation 'com.squareup.okhttp3:okhttp:3.11.0'
}

创建request，输入AK和SK，并指定域名、方法名、请求uri和body。

    
         Request request = new Request();
try {
// Directly writing AK/SK in code is risky. For security, encrypt your AK/SK and store them in the configuration file or environment variables.
// In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, set environment variables HUAWEICLOUD_SDK_AK and HUAWEICLOUD_SDK_SK.
        request.setKey(System.getenv("HUAWEICLOUD_SDK_AK"));   
        request.setSecret(System.getenv("HUAWEICLOUD_SDK_SK"));
        request.setMethod("GET");
        request.setUrl("https://service.region.example.com3/v1/{project_id}/vpcs");
        request.addQueryStringParam("name", "value");
        request.addHeader("Content-Type", "text/plain");
        //request.setBody("demo");
} catch (Exception e) {
	e.printStackTrace();
	return;
}

对请求进行签名，生成okhttp3.Request对象来访问API。

    
         okhttp3.Request signedRequest = Client.signOkhttp(request);
OkHttpClient client = new OkHttpClient.Builder().build();
Response response = client.newCall(signedRequest).execute();
