报错：

[HPM] Error occurred while trying to proxy request /oauth/validate from localhost:8080 to localhost:8081 (ENOTFOUND) (https://nodejs.org/api/errors.html#errors_common_system_errors)

设置代理:

 '/xxxxx': {
            target:"localhost:8081",
            changeOrigin: true, //可否跨域
            pathRewrite: {
                '^/xxxxx': '' //重写接口，去掉/paas
            }
        }

代理要是完整的url, http://localhost:8081, http 不能少。
