@H_301_1@在登录屏幕上的react-native应用程序中,我正在努力在输入错误的用户名/密码组合后为用户提供良好的错误消息.要与API交互我正在使用Axios库.但是当我在catch语句中出现错误时,我收到这个丑陋的错误消息,说我有一个“未处理的承诺拒绝”,我不能做诸如设置组件状态或导航到新页面之类的事情.
我看不出我做错了什么,它看起来就像我在文档中看到的那样.
在我的表单提交功能中,我有：
axios.post('http://192.168.1.11:1337/login',{
email: this.state.username,password: this.state.password
}).then(function (response) {
// This stuff all seems to work great
console.log("The response we got: ",response);
if (response.status == 200) {
console.log("Status code equals 200");
Actions.homepage();
}
}).catch(function (err) {
// Run into big problems when I get an error
console.log("Got an error logging in,here's the message: ",err);
});
谁能看到我在这里做错了什么？
附：这是我从服务器返回的错误消息,它从该console.log中记录(“登录时出错,这里是消息：”,错误);：
"Got an error logging in,here's the message:"
