Javascript 获取xhr.js:184获取http://localhost:8600/user-service/userbyid/[object%20Object]400甚至url是否正确?
获取xhr.js:184获取http://localhost:8600/user-服务/userbyid/[object%20Object]400用于(“http://localhost:8600/user-service/userbyid/“+{used})其中used是分配给props值的变量? 任何我能够在我的console.log中打印“used”值的方法都是正确的,即使在我使用postman获取它时,也会给我输出。那么为什么这个反应部分没有给出输出呢Javascript 获取xhr.js:184获取http://localhost:8600/user-service/userbyid/[object%20Object]400甚至url是否正确?,javascript,reactjs,spring,spring-mvc,Javascript,Reactjs,Spring,Spring Mvc,获取xhr.js:184获取http://localhost:8600/user-服务/userbyid/[object%20Object]400用于(“http://localhost:8600/user-service/userbyid/“+{used})其中used是分配给props值的变量? 任何我能够在我的console.log中打印“used”值的方法都是正确的,即使在我使用postman获取它时,也会给我输出。那么为什么这个反应部分没有给出输出呢 import axios from
