Does uniapp WeChat authorization require a button?

In uniapp, if you need to use the WeChat authorized login function, do you have to use a button to trigger it? This is a problem that many developers often encounter.

First, let’s understand the relationship between uniapp and WeChat authorization. Based on the development of uniapp, we can obtain the code value in the WeChat interface through the uni.login() method, but if we want to obtain more user information, such as user avatar, nickname and other information, we need to use WeChat's authorized login interface . Therefore, using the WeChat authorized login function allows us to obtain more user information, thereby better conducting user data analysis and user behavior analysis.

Next, back to the question itself, does it have to be triggered by a button to authorize login? The answer is not necessarily. According to the developer's needs and actual situation, appropriate triggering methods can be selected in different scenarios.

For example, for a small program, since the page itself has a Tab bar at the bottom, we can choose to provide a Tab in it and directly set it to "Authorized login", and the user can click to authorize. At this point, we don't need to use buttons to trigger.

In addition, for some scenarios of connecting with other social media platforms, we can choose to add a social media authorized login tab at the top of the page. After the user clicks, the login buttons of multiple social media platforms will be displayed, including WeChat. Login button. At this time, in this scenario, we can also trigger without using buttons.

But it should be noted that if we set a button inside the page for WeChat authorized login, then before the user clicks this button, we need to use the uni.getUserInfo() method to obtain the user's authorization. Information, if the user is not authorized, an authorization request pop-up box will pop up. After obtaining the user's authorization, a prompt will be displayed on the button, and the user will click to authorize the login.

To sum up, for uniapp and WeChat authorized login, we do not need to use buttons to trigger, but need to judge based on the actual situation and choose the appropriate trigger method to achieve better user experience experience.
