问题描述
我正在开发一个运行在 Capacitor 之上的 Ionic React 应用程序。它适用于浏览器中的 axios 请求,但在 Android 上我有 CORS
问题,这就是我使用 community HTTP plugin
的原因:https://github.com/capacitor-community/http
示例:我点击了我的登录按钮。我的电子邮件和密码等数据应该通过 HTTP post 发送,但它捕获了我在那里放置的错误:再试一次。
你知道它为什么会发生吗?
也没有关于 Android Studio 请求的错误日志。只有这些:
/system_process E/ClipboardService: Denying clipboard access to com.google.android.googlequicksearchBox,application is not in focus nor is it a system service for user 0
E/netmgr: qemu_pipe_open_ns:62: Could not connect to the ‘pipe:qemud:network’ service: Invalid argument
E/netmgr: Failed to open QEMU pipe ‘qemud:network’: Invalid argument
E/wifi_forwarder: qemu_pipe_open_ns:62: Could not connect to the ‘pipe:qemud:wififorward’ service: Invalid argument
E/wifi_forwarder: RemoteConnection Failed to initialize: RemoteConnection Failed to open pipe
为了解决这些错误,我在 application
元素中添加了此设置:
android:usesCleartextTraffic=“true”
但错误仍然发生。
Android 模拟器已连接到 Internet。

登录.tsx:
import React from "react";
import { useHistory } from "react-router-dom";
import { useState,useContext } from "react";
import MyContext from "../my-context";
import {
IonPage,IonHeader,IonContent,IonButton,IonInput,IonLabel,IonItem,IonGrid,IonCol,IonAlert,} from "@ionic/react";
import { Http,HttpResponse } from "@capacitor-community/http";
const Login = () => {
const history = useHistory();
const {
email,setEmail,password,setPassword
} = useContext(MyContext);
const doLogin = async (e: any) => {
e.preventDefault();
const loginData = {
email: email,password: password,};
//https://github.com/capacitor-community/http
const options = {
url: "https://xx/login,data: loginData,};
const response: HttpResponse = await Http.post(options)
.then((response) => {
if (response.data.token) {
history.push("/home");
window.location.reload();
}
return response.data;
})
.catch((error) => {
setMessage(
"Try again!"
);
setIserror(true);
});
};
return (
<IonPage>
<IonContent className="ion-padding ion-text-center">
<IonGrid>
<IonRow>
<IonCol>
<IonAlert
isOpen={iserror}
onDiddismiss={() => setIserror(false)}
header={"Info!"}
message={message}
buttons={["Ok"]}
/>
</IonCol>
</IonRow>
<h1>Login</h1>
</IonCardTitle>
<IonItem>
<IonLabel position="floating">Email</IonLabel>
<IonInput
name="email"
type="email"
value={email}
onIonChange={(e) => setEmail(e.detail.value!)}
/>
</IonItem>
<IonItem>
<IonLabel position="floating">Password</IonLabel>
<IonInput
name="password"
type="password"
value={password}
onIonChange={(e) => setPassword(e.detail.value!)}
/>
</IonItem>
<IonButton onClick={doLogin}>Login</IonButton>
</IonGrid>
</IonContent>
</IonPage>
);
};
export default Login;
我从 3 天起就一直被这个问题困扰,所以任何帮助都会非常非常感激。谢谢!
解决方法
服务器是否收到了 HTTP 请求?您可以尝试打印日志以供判断。
这样我们就可以进行下一步了
,对于任何感兴趣的人,我找到了解决方案。在此文档 https://github.com/capacitor-community/http 中,Android 配置 缺失。
1- 因此,在 add http plugin
android\app\src\main\java\\MainActivity.java
package com.myapp.com;
import android.os.Bundle;
import com.getcapacitor.BridgeActivity;
import com.getcapacitor.Plugin;
import java.util.ArrayList;
import com.getcapacitor.plugin.http.Http; //added
public class MainActivity extends BridgeActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Initializes the Bridge
this.init(savedInstanceState,new ArrayList<Class<? extends Plugin>>() {{
// Additional plugins you've installed go here
// Ex: add(TotallyAwesomePlugin.class);
add(Http.class); //added
}});
}
}
2- 在 Android Studio 中同步 gradle 文件:
File --> Sync Project with Gradle Files
我根据自己的需要编写了请求,现在它完美无缺。
