Axios无法按预期处理500。遵循Axios error handling提供的方式,但是不起作用。
POST正在发送用户名/电子邮件和密码,但是故意将密码设置为不正确的密码以测试错误处理。如果设置了正确的密码,则可以正常使用。
axios.post(
config.apiGateway.URL + ".../signin",
payload
).then(response => {
console.log(response)
if(response.status == 200){
console.log("Login successfull");
this.setState({token: response.data.JWT_TOKEN});
} else {
console.log(response.status)
this.setError()
}
}).catch(error => {
this.setError()
console.log(error)
if (error.response) {
console.log("--------------------------------------------------")
// 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) {
console.log("*************************")
// 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 {
console.log("++++++++++++++++++++++++")
// Something happened in setting up the request that triggered an Error
console.log('Error', error.message);
}
console.log(error.config);
})
应该执行是否执行了(error.response),但实际上执行了否则执行了 if(error.request)。

在Chrome开发者工具中,OPTIONS方法返回200,如下所示。

POST方法返回预期的500。

在Ubuntu 18 LTS中具有Google Chrome 70.0.3538.77的AXios 0.18.0。
请建议如何正确处理500个。
How to catch and handle error response 422 with Redux/Axios?似乎具有相同的错误问题,即将其设置为堆栈跟踪,并且似乎未填充响应。
编辑: 我仍然不明白为什么记录错误会返回该堆栈消息。我试图这样记录它。然后您实际上可以看到它是一个对象。
答案 0 :(得分:2)
您的问题只是...
为什么
error.response
不存在?
如果是这样,原因是因为处理您的POST
请求的资源没有响应Access-Control-Allow-Origin
标头,即使它针对飞行前的OPTIONS
请求也是如此。
由于有CORS政策,因此您的客户端代码被拒绝访问,因此未定义error.response
。
在错误处理程序中,您可以假定空的response
属性等于网络级问题。
