## 问题 ##

OkHttp请求后端接口， 控制台报错  
请求失败：java.net.ConnectException: failed to connect to localhost/127.0.0.1 (port 8080) from /127.0.0.1

### 详细问题 ###

2022-09-18 11:21:19.838 16731-18584/com.example.electronicmall D/ControlsProviderService: 请求失败：java.net.ConnectException: failed to connect to localhost/127.0.0.1 (port 8080) from /127.0.0.1 (port 56738) after 10000ms: isConnected failed: ECONNREFUSED (Connection refused)

### 解决方案 ###

采用本机网络地址替代localhost（在局域网的环境下考虑使用本机的地址169.254.x.x来代替localhost或者127.0.0.1）  
即将原url

String url = "http://localhost:8080/demo/getUserById"

改为该url

String url = "http://169.254.x.x:8080/demo/getUserById"
