当使用spring-cloud-feign连接到本地主机时，Feign找不到url，而是给我以下错误消息。

我的假客户端:

@FeignClient(name = "php", url = "http://localhost:4061/test")
interface PhpClient {
    @RequestMapping(method = [RequestMethod.POST])
    fun login(postData: LoginAction): PhpResponse
}

例如，当我将网址更改为 google.com 时，我可以看到请求已正确发送，并且 google 给出了响应。

使用Feign时如何正确访问localhost？

我可以使用 Postman 到达端点，所以这不是问题。问题似乎具体在于 Feign 无法定位 localhost？

编辑:像这样切换到 OkHttp

Request.Builder()
            .url("http://localhost:4061/test")
            .build()

有效。为什么它不能与 feign 一起使用？

最佳答案

显然错误不是假装的，而是我试图连接到 phpstorm 内置服务器。

所以对我来说，解决方法是将 phpstorm 中的配置从 localhost 更改为 127.0.0.1。显然，当使用 localhost 时，phpstorm 更喜欢 IPv6。

关于java - Feign 无法连接到本地主机，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58835762/
