我有一个动作POST向服务器发出请求以更新用户的密码,但我无法处理链接的catch块中的错误.
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,这就是我所看到的:
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!
我在某个地方不知不觉地犯了错误吗？因为我正在处理来自不同请求的其他错误,但似乎无法正常工作.
Axios可能正在解析响应.我在我的代码中访问这样的错误:
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.
{
// `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 => )
编辑:
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.然后你可以看到它是一个物体.
console.log('errorType', typeof error);
console.log('error', Object.assign({}, error));
EDIT2:
经过一番调查之后,这就是您要打印的内容.这是一个Javascipt错误对象.爱可信则增强了这种错误与配置,代码和效应初探喜欢这样.
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'));
例
getUserList() {
return axios.get('/users')
.then(response => response.data)
.catch(error => {
if (error.response) {
console.log(error.response);
}
});
}
检查错误对象的响应,它将包含您正在查找的对象,以便您可以执行此操作 error.response.status
https://github.com/mzabriskie/axios#handling-errors
这是处理error对象的正确方法：
axios.put(this.apiBaseEndpoint + '/' + id, input)
.then((response) => {
// Success
})
.catch((error) => {
// Error
if (error.response) {
// The request was made and the server responded with a status code
// that falls out of the range of 2xx
// console.log(error.response.data);
// console.log(error.response.status);
// console.log(error.response.headers);
} else if (error.request) {
// The request was made but no response was received
// `error.request` is an instance of XMLHttpRequest in the browser and an instance of
// http.ClientRequest in node.js
console.log(error.request);
} else {
// Something happened in setting up the request that triggered an Error
console.log('Error', error.message);
}
console.log(error.config);
});
