Step 1. Prepare COS Bucket
Last updated: 2018-09-03 15:27:41PDF
Notes: 1. The source Bucket, target Bucket and function must reside in the same region. In this tutorial, South China (Guangzhou) region is used. 2. Two COS Buckets are required. If you use the same Bucket as both source and target buckets, each thumbnail uploaded to source bucket may trigger function again, therefore unnecessary recursion is generated.
1) Log in to the Tencent Cloud console, and select Cloud Object Storage.
2) Click the Create Bucket button in the Bucket List tab to create a new source COS Bucket.
3) Configure the name of COS Bucket, such as
mybucket, and set the region to
South China, access permission to default
Public read & Private write, CDN acceleration to default
Disabled, and click Save to create a new COS Bucket.
4) Create the target Bucket
mybucketresized in the same way.
5) Upload any image file to the source Bucket (i.e. mybucket). In this example, we use an image HappyFace.png for demonstration. (Before COS is associated, when manually calling the function to perform test and verification, you need to pass the sample data that contains this file to SCF, so that SCF can locate corresponding file according to this data. Therefore, you first need to create this sample object.)
