What should I do if 'Error: timeout of xxxms exceeded' occurs when using vue-resource in a Vue application?

In Vue application development, using vue-resource to make HTTP requests is a common operation. Although vue-resource provides many convenient functions, sometimes we encounter error messages such as "Error: timeout of xxx ms exceeded". This error is usually caused by a request timeout. So, in this case, how should we solve this problem?

1. Increase the request timeout period

First, we can try to solve the problem by increasing the request timeout period. In vue-resource, we can set the request timeout by configuring timeout. By default, the timeout is 30000ms (ie 30 seconds). If the request is not completed within this time, the "Error: timeout of xxxms exceeded" error will be returned.

We can set the timeout to 60 seconds in the following way:

Vue.http.options.timeout = 60000;

If you are making a particularly complex or lengthy request, you may consider setting the timeout longer. This allows enough time for the request to be responded to.

2. Check the network connection

In some cases, the "Error: timeout of xxxms exceeded" error may be caused by an unstable or disconnected network connection. Therefore, we need to check if our network connection is working properly. If your network connection is unstable or disconnected, you will need to reconnect to the network and re-execute your request.

3. Check whether the requested target is available

When we make an HTTP request, we are likely to request a target that does not exist or has not been started. In this case we also encounter “Error: timeout of xxxms exceeded” error. Therefore, we need to ensure that our request target is available and started.

4. Reduce the amount of requested data

In some cases, the "Error: timeout of xxxms exceeded" error may be caused by the amount of requested data being too large. If the amount of data we request is too large, the request will take longer to complete. In this case, we need to reduce the amount of requested data to shorten the request time.

5. Use a more efficient request method

If you make extensive use of sending multiple requests in a short period of time, it is recommended that you use a more efficient request method such as websocket or socket.io. This way you can respond to requests faster.

Summary

When using vue-resource to make HTTP requests in a Vue application, you may encounter the error message "Error: timeout of xxxms exceeded". This error is usually caused by request timeout, unstable network connection, unavailable request target, excessive request data volume, etc. To solve this problem, we can avoid or solve this problem by increasing the request timeout, checking the network connection, checking whether the request target is available, reducing the amount of request data, and using more efficient request methods.
