【问题描述】：
我正在使用 NativeScript 构建应用程序，因此我的 android 手机通过 USB 数据线连接到计算机进行调试。
但是当我在运行应用程序后尝试从手机发帖时，它一直给我这个错误：
System.err: java.net.ConnectException: Connection timed out
我都试过了，至今不知道是什么问题。
***当我尝试从“邮递员”发布到服务器时，它工作正常。
谢谢！
import { Injectable } from "@angular/core";
import { User } from "../viewModels/userViewModel/userViewModel";
import { HttpClient } from '@angular/common/http';
@Injectable()
export class UserService {
private serverUrl= "http://192.168.14.155:61986/api/Users/PostUser";
constructor(private http: HttpClient) {}
register(user:User){
console.log("you are joing to use "+user.email+" as your Email");
const req = this.http.post(this.serverUrl, {
username: user.email,
email: user.email,
password: user.password
}).subscribe(
res => {
console.log(res);
},
err => {
console.log("Error occured");
}
);
}
}
这些是累积的错误：

【问题讨论】：
-
你的手机和电脑在同一个网络吗？
-
否，但我也尝试将它们连接到同一个网络，但没有成功，我还尝试从手机打开热点并从计算机连接.. 两者都没有帮助。跨度>

when I try to post to the server from "Postman" it works fine.。是的。邮递员在您的 PC 上。但是在你的手机上试试邮递员。或者你局域网中的另一台电脑。
