zip -j helloworld.zip *.pyfunction_namehelloworld
package_filehelloworld.zip### Update the lambda code
aws lambda update-function-code \--function-name $function_name \--zip-file fileb://$package_file 或Java #!/bin/bash### Create the lambda package
mvn packagefunction_namehelloworld
package_filetarget/lambda-java-example-1.0-SNAPSHOT.jar### Update the lambda code
aws lambda update-function-code \--function-name $function_name \--zip-file fileb://$package_file 使脚本可执行文件chmod x update-lambda.sh并更新lambda ./update-lambda.sh 。 第2步传递一些东西给您的lambda 现在我们知道了如何更新云中的lambda让我们进行更改以便我们可以将某些内容作为参数传递。 与其说“你好世界” 我们希望它向任何人问好。 在Python中 def lambda_handler(event, context):return Hello {}!.format(event[to]) 或类似于Java中的以下内容 package example;import com.amazonaws.services.lambda.runtime.Context;public class Hello {public String lambdaHandler(Request request, Context context) {return Hello request.getTo() !;}
}class Request {private String to;public void setTo(String to) { this.to to; }public String getTo() { return to; }
}步骤3告诉Lambda与任何人打招呼 aws lambda invoke --invocation-type RequestResponse --function-name helloworld --payload {to: whomever} output.txt 你应该看到谁你好 在输出文本中 步骤4让我们添加其余的API 将以下脚本粘贴到诸如create-api.sh的文件中更改该文件的执行权限然后执行该脚本。 深吸一口气…… 注意此脚本期望定义AWS_REGION和AWS_ACCOUNT_ID环境变量 #!/bin/bash
set -eregion$AWS_REGION
account_id$AWS_ACCOUNT_IDecho Creating a new API and capturing its ID ...
api_id$(aws apigateway create-rest-api \--name HelloWorldAPI \--description Hello World API \--output text \--query id)
echo API ID is: $api_idecho Storing the API ID on disk - well need it later ...
echo $api_id api_id.txtecho Geting the root resource id for the API ...
root_id$(aws apigateway get-resources \--rest-api-id ${api_id} \--output text \--query items[?path/].[id])
echo root_id$root_idecho Creating a resource for the /hello path
resource_id$(aws apigateway create-resource \--rest-api-id ${api_id} \--parent-id ${root_id} \--path-part hello | jq -r .id)
echo Resource id is $resource_idecho Creating the GET method on the /hello resource
aws apigateway put-method \--rest-api-id ${api_id} \--resource-id ${resource_id} \--http-method GET \--authorization-type NONE echo Integrating the GET method to lambda. Note that the request tempalate uses API Gateway template language to pull in the query parameters as a JSON event for the lambda.
aws apigateway put-integration \--rest-api-id ${api_id} \--resource-id ${resource_id} \--http-method GET \--type AWS \--request-templates { application/json: {\n #foreach($param in $input.params().querystring.keySet())\n \$param\: \$util.escapeJavaScript($input.params().querystring.get($param))\ \n #end\n } } \--integration-http-method POST \--uri arn:aws:apigateway:${region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${region}:${account_id}:function:helloworld/invocationsecho Creating a default response for the GET method
aws apigateway put-method-response \--rest-api-id ${api_id} \--resource-id ${resource_id} \--http-method GET \--status-code 200 echo Creating a default response for the integration
aws apigateway put-integration-response \--rest-api-id ${api_id} \--resource-id ${resource_id} \--http-method GET \--status-code 200 \--selection-pattern .*echo Adding permission for the API to call the lambda for test so we can use the console to make the api call
aws lambda add-permission \--function-name helloworld \--statement-id apigateway-helloworld-get-test \--action lambda:InvokeFunction \--principal apigateway.amazonaws.com \--source-arn arn:aws:execute-api:${region}:${account_id}:${api_id}/*/GET/helloecho Adding permission for the API to call the lambda from any HTTP client
aws lambda add-permission \--function-name helloworld \--statement-id apigateway-helloworld-get \--action lambda:InvokeFunction \--principal apigateway.amazonaws.com \--source-arn arn:aws:execute-api:${region}:${account_id}:${api_id}/api/GET/helloecho Creating a deployment
aws apigateway create-deployment \--rest-api-id ${api_id} \--stage-name api echo All done! you can invoke the api on https://${api_id}.execute-api.${region}.amazonaws.com/api/hello?towhomever步骤5调用API 脚本的最后输出提供了可以粘贴到浏览器中的URL。 您应该看到“你好你好”的回答。 一旦您点击进入浏览器。 步骤6清理 您可以使用上delete.sh创建的delete.sh脚本删除lambda。 删除api粘贴以下脚本并照常执行。 #!/bin/bash
echo Reading API id that I store in my create-api script
api_id$(api_id.txt)echo Removing the permissions from the lambda
aws lambda remove-permission \--function-name helloworld \--statement-id apigateway-helloworld-get
aws lambda remove-permission \--function-name helloworld \--statement-id apigateway-helloworld-get-testecho Deleting the API
aws apigateway delete-rest-api \--rest-api-id ${api_id}步骤7放松……结束 … 目前 翻译自: https://www.javacodegeeks.com/2016/05/aws-lambda-api-gateway.html
