Using an APIG (Dedicated) Trigger
For details about the APIG event source, see Supported Event Sources.
Prerequisites
You have created an API group, for example, APIGroup_test. For details, see Creating an API Group.
Creating an APIG Trigger
- Log in to the FunctionGraph console. In the navigation pane, choose Functions > Function List.
- On the Function List page, click Create Function in the upper right corner.
- Set the following parameters:
- Function Name: Enter a function name, for example, apig.
- Agency: Select Use no agency.
- Enterprise Project: Select default.
- Runtime: Select Python 2.7.
- Click Create.
- On the Code tab page, copy the following code to the code window and click Deploy.
# -*- coding:utf-8 -*- import json def handler (event, context): body = "<html><title>Functiongraph Demo</title><body><p>Hello, FunctionGraph!</p></body></html>" print(body) return { "statusCode":200, "body":body, "headers": { "Content-Type": "text/html", }, "isBase64Encoded": False }
- Choose Configuration > Triggers and click Create Trigger.
Figure 1 Creating a trigger
- Configure the trigger information.
Table 1 Trigger information Parameter
Description
Trigger Type
Select API Gateway (Dedicated Gateway).
API Instance
Select an instance. If no instance is available, click Create Instance.
API Name
Enter an API name, for example, API_apig.
API Group
An API group is a collection of APIs. You can manage APIs by API group.
Select APIGroup_test.
Environment
An API can be called in different environments, such as production, test, and development environments. APIG supports environment management, which allows you to define different request paths for an API in different environments.
To ensure that the API can be called, select RELEASE.
Security Authentication
There are three authentication modes:
- App: AppKey and AppSecret authentication. This mode is of high security and is recommended. For details, see App Authentication.
- IAM: IAM authentication. This mode grants access permissions to IAM users only and is of medium security. For details, see IAM Authentication.
- None: No authentication. This mode grants access permissions to all users.
Select None.
Protocol
There are two types of protocols:
- HTTP
- HTTPS
Select HTTPS.
Timeout (ms)
Enter 5000.
- Click OK.
Figure 2 Creating a trigger
NOTE:
- URL indicates the calling address of the APIG trigger.
- After the APIG trigger is created, an API named API_apig is generated on the APIG console. You can click the API name in the trigger list to go to the APIG console.
Invoking the Function
- Enter the URL of the APIG trigger in the address bar of a browser, and press Enter.
- View the execution result, as shown in Figure 3.
NOTE:
- The input for APIG invocation comes from an event template provided by the function. For details, see Table 2.
- The function response for APIG invocation is encapsulated and must contain body(String), statusCode(int), headers(Map), and isBase64Encoded(boolean).
Viewing the Execution Result
- Return to the FunctionGraph console. In the navigation pane, choose Functions > Function List.
- Click a function to go to the function details page.
- Choose Monitoring > Logs to query function running logs.
