Axios网络错误与React native, Nodejs, Express, MongoDB &

Question

我正试图开发使应用程序与服务器。我有下面的设置。
React native Expo-cli
nodejs + express
mongodb

有一些麻烦连接客户端程序和服务器程序与物理android手机和ios手机。
我通过ssh登录linux服务器程序，它的ip地址和使用的端口如下
服务器ip: 102.249.18.175
端口:443

部分前端代码如下

try {
const response = await axios.post(
"http://192.249.18.175:443/userAuth/signin",
{
email,
password,
}
);
console.log("signin response: ", response);
if (response.data.succ) {
return Alert.alert("로그인 성공");
} else {
// login fail ...
return Alert.alert("로그인 정보가 맞지 않습니다, 다시 입력해주세요");
}
} catch (e) {
const errorResponse = (e as AxiosError).response;
console.error(errorResponse);
// if (errorResponse) {
//   Alert.alert("알림", errorResponse.data.message);
// }
console.log("Hello world!");
return Alert.alert(`Error: ${JSON.stringify(e.response)}`);
}

这是后端代码的一部分

app.post("/userAuth/signin", async (req, res) => {
const { email, password } = req.body;
console.log(req.body);
isLocated = await userAuth.find({ email: email, password: password });
if (isLocated) {
res.status(200).json({ succ: true });
} else {
res.status(404).json({ succ: false });
}
});

这是控制台记录的输出，它是e.response

我成功连接到服务器和mongodb。

[nodemon] 2.0.19
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node index.js`
Server started at 443
connected to mongoDB

你对这个问题有什么见解吗?
感谢您阅读这篇文章。

问题可能是您尝试通过HTTP发出请求。对于android，尝试像这样启用明文网络流量:

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:usesCleartextTraffic="true"
...>
...
</application>
</manifest>

类似地，在iOS上，你有NSAppTransportSecurity设置。您可以修改"信息"。列表文件如下:

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

要小心，您应该只允许开发HTTP流量。请确保在生产环境中恢复这些更改。
