Java SDK
A synchronous function execution SDK is used as an example. To use the sample code, you must add the SDK dependency with the same language.

The request/response parameters and example requests/responses of the SDK are the same as those of the corresponding APIs. For details about the parameters and examples, see the API for executing a function synchronously.
SDK Request Example
package com.huaweicloud.sdk.test; import com.huaweicloud.sdk.core.auth.ICredential; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ConnectionException; import com.huaweicloud.sdk.core.exception.RequestTimeoutException; import com.huaweicloud.sdk.core.exception.ServiceResponseException; import com.huaweicloud.sdk.functiongraph.v2.region.FunctionGraphRegion; import com.huaweicloud.sdk.functiongraph.v2.*; import com.huaweicloud.sdk.functiongraph.v2.model.*; public class InvokeFunctionSolution { public static void main(String[] args) { // This example is only used for testing purposes. Do not hardcode your AK/SK in the production environment. String ak = "<YOUR AK>"; String sk = "<YOUR SK>"; ICredential auth = new BasicCredentials() .withAk(ak) .withSk(sk); FunctionGraphClient client = FunctionGraphClient.newBuilder() .withCredential(auth) .withRegion(FunctionGraphRegion.valueOf("<region>")) .build(); InvokeFunctionRequest request = new InvokeFunctionRequest(); Map<String, Object> listbodyInvokeFunctionRequestBody = new HashMap<>(); listbodyInvokeFunctionRequestBody.put("k", "v"); request.withBody(listbodyInvokeFunctionRequestBody); request.withFunctionUrn("urn:fss:<region>:<project_id>:function:default:<func_name>:<version>"); request.withXCffLogType("tail"); request.withXCFFRequestVersion("v1"); try { InvokeFunctionResponse response = client.invokeFunction(request); System.out.println(response.toString()); } catch (ConnectionException e) { e.printStackTrace(); } catch (RequestTimeoutException e) { e.printStackTrace(); } catch (ServiceResponseException e) { e.printStackTrace(); System.out.println(e.getHttpStatusCode()); System.out.println(e.getErrorCode()); System.out.println(e.getErrorMsg()); } } }
Obtain AK/SK, region (endpoint), and project_id by referring to AK/SK Signing and Authentication Guide.
Obtain func_name and version from the function details page.
X-CFF-Request-Version indicates the response body format. v0: text format; v1: JSON format. Select this format when using an SDK.
