What happens when uniapp third-party login does not display?

Recently, some UniApp developers found that the login button could not be displayed properly when using third-party login. This problem not only troubles developers, but also inconveniences users. So, what are the reasons for this? How to solve it?

1. Possible reasons

1. The third-party login plug-in version is too low

Using third-party login in UniApp usually requires the help of a plug-in. If the plug-in version is too low, some problems may occur. Therefore, developers need to update plug-ins in a timely manner to ensure that the plug-in version is the latest.

2. The third-party platform configuration is incorrect

When implementing third-party login, we also need to configure the relevant information of the third-party platform. This information includes:

(1) AppID: The ID number that identifies the application and is the unique identifier for interaction with third-party platforms.

(2) AppSecret: Application key, used to verify the legitimacy of the application.

(3) Redirect URL: callback address, used to guide users back to our application from the third-party platform.

If these information are configured incorrectly, the login button will not be displayed properly.

3. The authorized domain name is not set

When using a third-party login, we need to set the authorized domain name to our application domain name. If the authorized domain name is not set or is set incorrectly, the login button will not be displayed properly.

2. How to solve the problem?

1. Update the third-party login plug-in

If the third-party login plug-in version is too low, we need to upgrade the plug-in in time. For specific operation methods, please refer to UniApp official documentation.

2. Check the third-party platform configuration

Open the developer backend of the third-party platform and check whether the AppID, AppSecret and Redirect URL are configured correctly. If there are errors, the configuration needs to be modified in time.

3. Set the authorized domain name

In the developer backend of the third-party platform, set the authorized domain name to our application domain name. Generally, the authorized domain name needs to be the same as the application domain name.

4. Check the network connection

Sometimes, the login button cannot be displayed normally because the network connection is unstable. Developers can check whether the network connection is normal to ensure that the login button can be displayed normally.

In short, UniApp’s third-party login function is very practical and provides convenience to users. However, when using this function, we need to pay attention to the configuration and ensure that all parameters are set correctly. If you encounter a problem, we can troubleshoot it according to the above methods. I hope this article can help you better use UniApp’s third-party login function.
