Volcengine SDK Generator

Generate ordinary Volcengine API call examples by default. Keep the default output focused on the API call itself: authentication setup, request object/params, invocation, and printing the response. Do not add retry, proxy, connection pool, debug logging, or other advanced SDK configuration unless the user explicitly asks for those topics.

For advanced SDK configuration questions, use the language-specific files under references/. These reference files are self-contained; answer from them directly.

Core Rules

• API discovery uses scripts/rg_rank.py, which calls API Explorer search with both Channel=service and Channel=api. After a concrete API is selected, call scripts/make_code.py in direct mode with --service-code, --api-version, and --action.
• API discovery is online-only. The search endpoint does not require cookies, login state, UID, DID, UUID, or browser-specific headers. The script sends only Query, Channel, Limit, and Offset as query parameters.
• rg_rank.py preserves Channel=api order except for version selection: when the same service_code + action has multiple versions and the user did not specify one, it moves the result with IsRecommended=1 ahead of the other versions in that group. It also includes Channel=service results as separate service metadata.
• If online search fails, report the returned search errors. Do not guess an API or fall back to a bundled catalog.
• Use the user's original request as --query; do not rewrite it into a guessed API name or SDK method.
• Extract a shorter --query only when the user clearly self-corrects with words such as 等等, 不对, 重新来, 我改主意, 其实想要, 其实是想要, 应该是, or 改成; the extracted query must be a continuous substring from the user request, not a guessed API name.
• When multiple resources or services appear without a clear self-correction, run rg_rank.py once with the original request. If the returned candidates remain ambiguous, list them concisely and ask the user to choose.
• Pure-generic queries such as api, sdk, or demo are sent online but are likely to be ambiguous. Refine the query with a concrete resource or action word.
• ServiceCode is case-sensitive. Preserve the exact service_code value from the selected API record when calling make_code.py; for example, Kafka is not kafka.
• When the same service_code + action appears in multiple API versions and the user did not specify a version, select the result with is_recommended=true even if its remote_rank is lower. If the user specified a version, use that exact version.
• Fetch api-swagger only after a concrete API is selected.
• The api-swagger fetch may include both Version and APIVersion because that endpoint expects them; the make-code payload must not include Version.
• Call make-code with ApiAction, ServiceCode, APIVersion, Region, and Params.
• Do not send Version to make-code.
• Params must come from the user. Do not auto-fill from swagger demos.
• Swagger is used for API metadata, required parameter hints, and lightweight validation. Do not serialize query arrays, form arrays, or .N parameters for make-code; pass the user’s JSON object as Params.
• If the user omits required top-level parameters, mock only those top-level required parameters and clearly mark them as mock values. Do not mock optional parameters. If a required top-level parameter is an object or array, recursively fill only required child fields/items.
• Mock values must be derived from the fetched swagger first: prefer example, then examples, then default, then enum, then type/constraint-aware fallback. If a swagger example is masked, such as **** or XX, skip it and use a valid fallback value.
• Mock comments must be in Chinese by default and placed near the mocked assignment line when the target language supports line comments; do not add a duplicate mock banner at the top of the returned code.
• Returned SDK code must print the API response value. The script post-processes fixed make-code templates for Python, Go, Java, and PHP to assign the response and print it.
• Return the code generated by scripts/make_code.py as the primary SDK example. Do not rewrite SDK request construction, authentication setup, or response handling into a custom application unless the user explicitly asks for that. If optional formatting or convenience logic is added, keep the generated active response print, such as print(resp), fmt.Println(resp), System.out.println(resp), print_r($response), or console.log(response).
• If language is not specified, return all languages from DemoSdk.
• SDK install/dependency info is a separate, on-demand capability. Only when the user explicitly asks how to install the SDK or which package/version to use (keywords such as 依赖, 安装, install, 版本, 包, maven, go get, pip, composer, npm), run scripts/sdk_info.py with --service-code and --api-version (reuse the selected API's values; add --language to filter to one of go/python/java/php/nodejs). It returns the live install command (RunCommand) plus package and version per language. Do NOT run it during normal code generation.
• If the API match is ambiguous, show concise candidates and ask the user to choose one. Do not add follow-up execution boilerplate such as saying that you will fetch swagger, mock required params, and call make-code after the user chooses.

Workflow

1. Parse the user request:

   • API hint: action, Chinese name, service code, or natural-language description.
   • Language: Python, Go, Java, PHP, cURL, Node.js, or unspecified.
   • Params: JSON object supplied by the user.
   • Region: user value or default cn-beijing.

2. Locate or validate the API once for every request. If the user already provides service_code, api_version, and action, use those exact values in direct mode; make_code.py verifies them through the online api-swagger response. For natural-language requests, call scripts/rg_rank.py with --query first. Use the full original request unless a clear self-correction keyword points to a later target; in that case use the final target substring.

3. After selecting service_code, api_version, and action, call scripts/make_code.py in direct API mode with --service-code, --api-version, and --action. If top-level required params are missing, the script fills only those required top-level params with swagger-derived mock values and annotates the returned code in Chinese. Ask for clarification only when API selection is genuinely ambiguous in the online results; in that clarification, only list candidates and ask the user to choose.

4. Once params are available, call make-code through the script and return the official code. Do not transform the generated sample into a hand-written utility; any custom formatting must be secondary and must preserve the active response print.

Commands

Search online candidates:

python3 scripts/rg_rank.py \
  --query '角色扮演' \
  --limit 10 \
  --format text

Direct API mode:

In TRN examples, <account-id> is the Volcengine account ID segment, such as a masked 2134xxxyyy.

python3 scripts/make_code.py \
  --service-code sts \
  --api-version 2018-01-01 \
  --action AssumeRole \
  --language python \
  --params-json '{"DurationSeconds":3600,"RoleSessionName":"demo","RoleTrn":"trn:iam::<account-id>:role/demo"}'

Use --refresh-swagger when API Explorer metadata has just changed or generated code looks stale:

python3 scripts/make_code.py \
  --service-code sts \
  --api-version 2018-01-01 \
  --action AssumeRole \
  --refresh-swagger \
  --params-json '{}'

Fetch SDK install/dependency info on demand (only when the user asks about install, package, or version):

python3 scripts/sdk_info.py \
  --service-code sts \
  --api-version 2018-01-01 \
  --language go
