本地客户端或网关自动提取三维文件结构，完成文件哈希校验与去重。 // Assuming file structure extraction logic function extractFileStructure(input) { // Placeholder for actual implementation. Requires recursive traversal based on the file type (e.g. obj, stl, dxf) // and parsing the content. let structure = {}; // Simulate extraction if (input.endsWith('.obj')) { structure = { 'vertices': 1000, 'faces': 500 }; } return structure; } // Assuming hash calculation logic function calculateFileHash(fileContent) { // Placeholder for actual implementation. Uses a cryptographic hash (e.g., SHA-256) function. let hash = "placeholder_hash_" + Math.random().toString(36).substring(2, 15); // Simulate hashing return hash; } // Assuming deduplication logic function deduplicateFiles(fileHashes) { // Placeholder. Needs to compare calculated hashes, identify duplicates. let uniqueFiles = {}; for (let file of fileHashes) { if (!uniqueFiles[file.hash]) { uniqueFiles[file.hash] = file.filePath; } } return Object.values(uniqueFiles); // Return only unique filepaths } // Example Usage (replace with actual file input and output) let fileInput = "example.obj"; // Simulate filename let fileStructure = extractFileStructure(fileInput); // Simulate file content read let fileContent = "This is some dummy content for the file"; let fileHash = calculateFileHash(fileContent); // Consider a list of file hashes and path. let files = [{ filePath: "file1.obj", hash: "hash1" }, { filePath: "file2.stl", hash: "hash2" }, {filePath: "file1.obj", hash: "hash1"}]; // Simulate hash list let uniqueFiles = deduplicateFiles(files); console.log("Unique files:", uniqueFiles); // Construct the response in JSON format (simulated) let response = { 'fileStructure': fileStructure, 'fileHash': fileHash, 'uniqueFiles': uniqueFiles }; // Output - format this into whatever is requested for response document.write(JSON.stringify(response, null, 2));
