我最近创建了一个Expo项目,该项目可以在iOS / Web上正常运行,但是在Android设备上却出现标题中描述的错误。
发生的事情是,该应用程序打开,并在按下按钮时打开了登录屏幕,该屏幕上显示了巫婆的登录屏幕。
POST请求看起来像这样:
_userLogin() {
let username = this.state.username;
let password = this.state.password;
fetch("https://domain/login-react", {
method: "POST",
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
'Accept-Encoding': 'gzip,deflate'
},
body: JSON.stringify({
username: username,
password: password,
}),
})
.then((response) => response.json())
.then((responseData) => {
if(responseData.status == 1) {
//saving user
this.setState({isLoggedIn: responseData.status});
this.setState({detaliiUser: responseData.detaliiUser});
AsyncStorage.setItem('USER_ID',JSON.stringify(this.state.detaliiUser['Id']));
//redirect to products page
this.props.navigation.navigate('Liste Utilizator');
}else{
this.setState({mesajEroare: responseData.status});
}
})
}
出于隐私原因,我替换了实际的提取网址
在我的app.json
中,android权限配置如下:
"android": {
"permissions" : ["ACCESS_COARSE_LOCATION", "ACCESS_FINE_LOCATION", "CAMERA", "INTERNET"],
"adaptiveIcon": {
"foregroundImage": "./assets/adaptive-icon.png",
"backgroundColor": "#FFFFFF"
},
"package": "app.htgps.listare"
},
我得到的错误:
[Unhandled promise rejection: TypeError: Network request failed]

另一个奇怪的事情是,当我运行expo build:android
时,该应用程序不会在我测试运行“ Android 10”的设备上请求任何许可
过去2天,我用Google搜索,并尝试了多种可能的解决方案,但找不到适合我的解决方案。
我可以提供任何帮助,也感谢任何形式的建议。
谢谢,CR
