Implementation Reference
- src/tools/api/requests.ts:34-73 (handler)The PostRequestTool class containing the execute method that implements the core logic for performing HTTP POST requests using Playwright's APIRequestContext.
export class PostRequestTool extends ApiToolBase { /** * Execute the POST request tool */ async execute(args: any, context: ToolContext): Promise<ToolResponse> { return this.safeExecute(context, async (apiContext) => { // Check if the value is valid JSON if it starts with { or [ if (args.value && typeof args.value === 'string' && (args.value.startsWith('{') || args.value.startsWith('['))) { try { JSON.parse(args.value); } catch (error) { return createErrorResponse(`Failed to parse request body: ${(error as Error).message}`); } } const response = await apiContext.post(args.url, { data: typeof args.value === 'string' ? JSON.parse(args.value) : args.value, headers: { 'Content-Type': 'application/json', ...(args.token ? { 'Authorization': `Bearer ${args.token}` } : {}), ...(args.headers || {}) } }); let responseText; try { responseText = await response.text(); } catch (error) { responseText = "Unable to get response text"; } return createSuccessResponse([ `POST request to ${args.url}`, `Status: ${response.status()} ${response.statusText()}`, `Response: ${responseText.substring(0, 1000)}${responseText.length > 1000 ? '...' : ''}` ]); }); } } - src/tools.ts:254-271 (schema)Input schema definition for the playwright_post tool, specifying parameters like url, value, token, and headers.
