Related to hugegraph/hugegraph-toolchain#103. POST /api/v1/tasks currently returns {"code":200} without creating a task, so clients can report a submission that never happened.

Return HTTP 405, Allow: GET and explicit /api/v1/tasks/create guidance for task-collection POST. Cover both versioned and legacy routes, several request bodies and authentication-filter ordering. Correct the native task/PageRank examples, including the flat parameter map and singular /task/{id} status route.

Validation: Go 1.23.7 go test -tags=dev ./apps/master/services -count=1 passes. The new rejection regression fails on the original code with HTTP 200 for all six route/body cases; the authentication regression continues to return 401 before the handler. The dev tag supplies the repository's development asset filesystem; no UI asset changes or large-dataset algorithm validation are claimed. gofmt and git diff --check pass.

Paired bilingual website docs: org #56 / apache #552. Coordinate the documented method behavior with the deployed Vermeer image. Change size: 201 lines including tests and corrected examples.

Summary by CodeRabbit

  • Bug 修复
    • 对任务集合发起 POST 请求时,现在会返回 HTTP 405,并通过 Allow: GET 标明该接口仅支持读取;错误信息会提示任务创建路径。
    • /tasks 和 /api/v1/tasks 均保留认证校验,未认证请求仍会收到 HTTP 401。
  • 文档
    • 更新 API 说明及 PageRank 示例,涵盖提交与轮询任务、查询结果、参数格式、权限要求和 Worker 输出路径。
    • 补充 HugeGraph 数据源参数及部署配置说明。

ASF upstream: 🔗 apache/hugegraph-computer #368

Return method-not-allowed instead of a false success for task collection POST.
Cover versioned and legacy routes and retain authentication filters.
Correct task submission and PageRank HTTP examples.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 2 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
