What to do if uniapp post does not take effect

As a UniApp developer, you may encounter some problems. One of the problems is caused by the post request not taking effect. This question may stress you out, but don't worry. In this article, we will explore some methods to solve the problem of UniApp post request not working.

First, check if your code is correct. When writing UniApp code, the correct way of writing is very important. Please make sure you don't enter the wrong code when sending the post request. When sending a POST request, you need to pay attention to the following points:

1. Whether the url link is correct
2. Whether 'Content-Type' is specified as 'application/json'
3. Whether the data to be sent is formatted correctly

Secondly, check whether there are cross-domain issues. Cross-origin is a very common problem that may cause post requests to fail. Cross-domain occurs when you send data to another domain name through a post request. The solutions generally include the following:

1. Add CORS cross-domain configuration to the back-end code
2. Use proxyTable for proxy forwarding in uni-app
3. In Add the withCredentials to true parameter when requesting

Again, check whether your server can receive the request. Sometimes, post requests are still sent to the server, but the server cannot parse the data correctly. At this time, we need to confirm whether the server can correctly receive the POST request.

Finally, if none of the above fixes the problem, you'll need to examine the code more deeply and debug it. You can use Chrome development tools to check whether the request is sent successfully and whether the server parses the request correctly. This will help you find errors faster and fix them.

To sum up, there may be many reasons and solutions for the problem of UniApp post request not taking effect. It should be noted that when writing code, try to reduce the chance of errors as much as possible, and at the same time do a good job in debugging and maintaining the code.
