如何使用 Redux/Axios 捕获和处理错误响应 422? [英] How to catch and handle error response 422 with Redux/Axios?
问题描述
我有一个操作向服务器发出 POST
请求以更新用户的密码,但我无法处理链式 catch 块中的错误.
I have an action making a POST
request to the server in order to update a user's password, but I'm unable to handle the error in the chained catch block.
return axios({
method: 'post',
data: {
password: currentPassword,
new_password: newPassword
},
url: `path/to/endpoint`
})
.then(response => {
dispatch(PasswordUpdateSuccess(response))
})
.catch(error => {
console.log('ERROR', error)
switch (error.type) {
case 'password_invalid':
dispatch(PasswordUpdateFailure('Incorrect current password'))
break
case 'invalid_attributes':
dispatch(PasswordUpdateFailure('Fields must not be blank'))
break
}
})
当我记录错误时,这是我看到的:
When I log the error this is what I see:
当我检查网络选项卡时,我可以看到响应正文,但由于某种原因我无法访问这些值!
When I check the network tab I can see the response body, but for some reason I can't access the values!
我是不是在不知不觉中犯了一个错误?因为我正在处理来自不同请求的其他错误,但似乎无法解决这个问题.
Have I unknowingly made a mistake somewhere? Because I'm handling other errors from different request fine, but can't seem to work this one out.
推荐答案
Axios 可能正在解析响应.我在我的代码中访问这样的错误:
Axios is probably parsing the response. I access the error like this in my code:
axios({
method: 'post',
responseType: 'json',
url: `${SERVER_URL}/token`,
data: {
idToken,
userEmail
}
})
.then(response => {
dispatch(something(response));
})
.catch(error => {
dispatch({ type: AUTH_FAILED });
dispatch({ type: ERROR, payload: error.data.error.message });
});
来自文档:
请求的响应包含以下信息.
The response for a request contains the following information.
{
// `data` is the response that was provided by the server
data: {},
// `status` is the HTTP status code from the server response
status: 200,
// `statusText` is the HTTP status message from the server response
statusText: 'OK',
// `headers` the headers that the server responded with
headers: {},
// `config` is the config that was provided to `axios` for the request
config: {}
}
所以 catch(error => )
实际上只是 catch(response => )
我仍然不明白为什么记录错误会返回该堆栈消息.我试着像这样记录它.然后你就可以真正看到它是一个对象.
I still dont understand why logging the error returns that stack message. I tried logging it like this. And then you can actually see that it is an object.
console.log('errorType', typeof error);
console.log('error', Object.assign({}, error));
编辑 2:
在查看更多这之后您正在尝试打印.这是一个 Javascipt 错误对象.Axios 然后通过配置、代码和响应来增强这个错误,比如 this.
After some more looking around this is what you are trying to print. Which is a Javascipt error object. Axios then enhances this error with the config, code and reponse like this.
console.log('error', error);
console.log('errorType', typeof error);
console.log('error', Object.assign({}, error));
console.log('getOwnPropertyNames', Object.getOwnPropertyNames(error));
console.log('stackProperty', Object.getOwnPropertyDescriptor(error, 'stack'));
console.log('messageProperty', Object.getOwnPropertyDescriptor(error, 'message'));
console.log('stackEnumerable', error.propertyIsEnumerable('stack'));
console.log('messageEnumerable', error.propertyIsEnumerable('message'));
