uniapp post error report

When developing the uniapp project, we sometimes encounter the problem of error reporting in post requests. This article will analyze the post request error problem in uniapp.

1. Error reporting phenomenon

When using uni.request to initiate a post request, if the following error message appears:

request:fail {"errMsg":"request:fail url not found"}

This means that the requested url does not exist.

2. Solution

1. Check whether the interface address is correct

First, we need to confirm whether the interface address is correct. You can test whether the interface is normal in tools such as postman. If the interface address is wrong, you can make corrections in time to avoid wasting time.

2. Check whether the parameters are correct

If the interface address is confirmed to be correct, then we need to carefully check whether the data sent by the post request is correct. You can print out the parameters of the post request on the server side to check if there are any errors. It is recommended to use tools such as postman to simulate requests to better troubleshoot problems.

3. Check cross-domain issues

When post requests encounter cross-domain issues, problems are likely to occur. We need to configure cross-domain request permission on the server side, or use the header attribute of uni.request to set the request header. For details, please refer to the relevant instructions in the uniapp official documentation.

4. Check whether the network connection is normal

Sometimes, our network connection is not stable and we may be unable to connect to the server. At this time, we need to check whether the network connection is normal, or use a third-party network debugging tool to detect network connectivity.

5. Check whether the back-end code is correct

If none of the above solutions solve the problem, then we need to carefully check whether the back-end code is correct. It may be a code logic error that prevents the request from being responded to properly.

3. Summary

When developing the uniapp project, the post request error problem may be caused by many reasons, and we need to investigate according to the specific situation. During the troubleshooting process, you can use logging and third-party network debugging tools to better handle the problem. I hope this article can help developers better handle post request error problems.
