# 历史、设计、未来

不久前，<a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">曾有 **FastAPI** 用户问过</a>：

> 这个项目有怎样的历史？好像它只用了几周就从默默无闻变得众所周知……

在此，我们简单回顾一下 **FastAPI** 的历史。

## 备选方案

有那么几年，我曾领导数个开发团队为诸多复杂需求创建各种 API，这些需求包括机器学习、分布系统、异步任务、NoSQL 数据库等领域。

作为工作的一部分，我需要调研很多备选方案、还要测试并且使用这些备选方案。

**FastAPI** 其实只是延续了这些前辈的历史。

正如[备选方案](alternatives.md){.internal-link target=_blank}一章所述：

        for (Thread thread : threads) {
            thread.join();
        }

        // Then - should complete without errors
        assertTrue(true, "Concurrent setFileId calls should complete without issues");
    }

    @Test
    @DisplayName("Should handle file ID with special patterns")
    void testSpecialFileIdPatterns() {
        // Test various special patterns
        byte[] allZeros = new byte[16];
