看代码里面主要是：

    getSocketPath() {
        /* istanbul ignore if */ /* only running tests on Linux; Window support is for local dev only */
        if (/^win/.test(process.platform)) {
            const path = require('path');
            return path.join('\\\\?\\pipe', process.cwd(), `server-${this.socketPathSuffix}`);
        } else {
            return `/tmp/server-${this.socketPathSuffix}.sock`;
        }
    }

官方文件说明这个长度是：It gets truncated to sizeof(sockaddr_un.sun_path) - 1, which varies on different operating system between 91 and 107 bytes. Identifying paths for IPC connections

我使用的是 阿里云的 fun 命令，不晓得 docker 是在什么环境下执行，请问如何才能查看查看这个具体的长度？

另外，这里文件长度变小一点，或者直接监听端口有没有问题？ 刚开始用Node，基础问题了解不多

同样的问题，你解决了吗

[ytfei]

没有解决。使用 unix file 做通信就有这个问题。我改了代码，用 端口通信就正常。

[basicfu]

用了这个包装所有的服务响应时间都增加了大概300ms左右，有知道是为什么吗，官方给的例子也是，本地最快响应也要300ms左右，去掉这个几ms就响应了

[ytfei]

你可以正常运行么？

[muxiangqiu]

已经解决
