如何在YouTube Data API v3上传代码中设置chunksize减少查询量
Hey there! Let’s get this sorted out—adjusting the chunk size will absolutely help cut down on the number of API requests per video upload, which should ease that 10,000 daily query limit. Here’s exactly where and how to make the changes:
1. Target the cors_upload.js File
Since this file handles all the AJAX-based chunked upload logic, this is where we’ll define the chunk size. Look for the CORSUploader class constructor (or the main upload initialization function) and add/modify the chunkSize parameter:
// Inside cors_upload.js, find the CORSUploader constructor function CORSUploader(options) { this.file = options.file; this.url = options.url; // Add or update this line to set your desired chunk size (e.g., 20MB) this.chunkSize = options.chunkSize || 20 * 1024 * 1024; // 20 megabytes per chunk this.offset = 0; this.chunkReader = new FileReader(); // ... rest of the existing constructor code }
2. Pass the Chunk Size from upload_video.js
Next, we need to pass this custom chunk size when creating the CORSUploader instance in upload_video.js. Locate where the uploader is initialized (usually in a method like startUpload or when handling file selection):
// Inside upload_video.js, find the code that creates the CORSUploader var uploader = new CORSUploader({ file: file, url: uploadUrl, chunkSize: 20 * 1024 * 1024, // Match the value you set in cors_upload.js onProgress: this.onUploadProgress.bind(this), onComplete: this.onUploadComplete.bind(this), onError: this.onUploadError.bind(this) });
3. Choose the Right Chunk Size
- Why larger chunks help: Each video chunk requires a separate API request. A bigger chunk size means fewer total chunks, so fewer requests per upload.
- Recommended starting point: Try 10MB to 50MB. Avoid sizes larger than 100MB, as this could lead to timeouts or upload failures depending on your network stability.
- Test incrementally: Start with a moderate size, monitor your API query usage, and adjust if needed.
Quick Notes
- Ensure both files use the same chunk size value to avoid inconsistencies.
- If you don’t see a
chunkSizevariable incors_upload.jsinitially, you’ll also need to update thefile.slice()calls (look for where chunks are read from the file) to usethis.offsetandthis.chunkSizeto define each chunk’s range.
