SBCL上的USocket：连接被拒绝（Drakma和Dex） [英] USocket on SBCL: connection refused (Drakma and Dex)
本文介绍了SBCL上的USocket：连接被拒绝（Drakma和Dex）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
运行简单的HTTP请求：
- 使用
dexador或drakma - 和SBCL 1.4.14
- 和OS X 10.13.6
- 带有
（ql：client-version）等于 2017-03-06和（defvar qlqs-info： *版本* 2015-01-28（我刚刚从 https://www.quicklisp.org/beta/ 通过 https：//beta.quicklisp .org / quicklisp.lisp ） - 通过Emacs + SLIME或仅通过命令行使用SBCL
（dex：get http：// localhost：8000 / wp-json / wp / v2 / posts）
失败，并显示错误（ dex stacktrace）

在 Clozure上运行相同的请求通用Lisp版本1.11.5（DarwinX8664）效果很好。
有人知道原因吗？

Running the same request on Clozure Common Lisp Version 1.11.5 (DarwinX8664) works good.
Does somebody know the reason?
解决方案
I had the same situation and I noticed my local services which Drakma tried to reach were ipv6 based, so they listened at ::1, when I set those service to listen at 127.0.0.1:xxxx explicitly instead of localhost:xxxx they became ipv4 and Drakma didn't complain any more.
这篇关于SBCL上的USocket：连接被拒绝（Drakma和Dex）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
