Implementation Reference
- src/index.ts:540-583 (handler)The handler function that implements the core logic of the 'get-function' tool. It retrieves detailed information about a specific function from Alibaba Cloud Function Compute (FC), including checks for custom domain configuration, using the FC SDK client.async (args) => { const { functionName, region } = args; const accessKeyId = process.env.ALIBABA_CLOUD_ACCESS_KEY_ID; const accessKeySecret = process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET; if (!accessKeyId || !accessKeySecret) { return { isError: true, content: [{ type: "text", text: `执行失败，请设置ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET, ALIBABA_CLOUD_SECURITY_TOKEN环境变量` }] }; } const accountId = await getAccountId(); if (!accountId) { return { isError: true, content: [{ type: "text", text: `执行失败，获取accountId异常` }] }; } const fcClient = createFcClient(region); let getFunctionResult; try { const getFunctionRequest = new GetFunctionRequest({}) getFunctionResult = await fcClient.getFunction(functionName, getFunctionRequest) } catch (error) { return { isError: true, content: [{ type: "text", text: `获取函数信息失败：${JSON.stringify(error as any)}` }] }; } const functionInfo = { ...getFunctionResult.body, } const autoDomainName = getAutoCustomDomainName(accountId, functionName, region); let getCustomDomainResult; try { getCustomDomainResult = await fcClient.getCustomDomain(autoDomainName); } catch (error: any) { if (error.statusCode !== 404) { return { isError: true, content: [{ type: "text", text: `获取函数域名信息失败：${JSON.stringify(error as any)}` }] }; } getCustomDomainResult = null; } if (getCustomDomainResult) { const routes = getCustomDomainResult.body?.routeConfig?.routes if (routes && routes.length == 1) { const route = routes[0]; if (route.functionName == functionName) { functionInfo.domain = autoDomainName; } } } return { content: [{ type: "text", text: `获取函数信息: ${JSON.stringify(functionInfo)}` }] }; }
