需要如何解决uni.startWifi is not a function

这个错误通常是因为在uni-app中调用了不存在的方法。可能的原因是：

1. 你的代码中调用了一个不存在的函数，或者函数名拼写错误。
2. 你的代码中调用了在当前环境中不可用的函数，比如在小程序端调用了H5端的函数。

为了解决这个问题，你可以尝试以下几个步骤：

1. 确认代码中调用的函数名称是否正确，包括大小写是否匹配。
2. 确认你的代码中是否正确引入了uni-app提供的API，可以参考uni-app官方文档中的API列表。
3. 确认你的代码是否在正确的环境中运行，例如在H5端调用了小程序端的API。

如果仍无法解决问题，建议将出错的代码段提供出来，以便更好地定位问题。

uni.startWifi is not a function

The error message "uni.startWifi is not a function" indicates that the method "startWifi" is not available in the current context.

This could be caused by a few different things.

Firstly, make sure that you are calling this method in the correct context, such as within a Vue component or in a JavaScript file that has access to the uni object.

Secondly, check if the "startWifi" method is supported by the version of the framework or library you are using. It is possible that this method is not available in the version you are using and you may need to update to a newer version.

Lastly, it could also indicate a typo in the method name or a missing import statement. Make sure that you have properly imported any necessary modules or libraries and that you have spelled the method name correctly.

uni.onShareAppMessage is not a function

根据提供的引用内容，当遇到"uni.onShareAppMessage is not a function"的错误时，可能是因为系统自带的空的onShareAppMessage函数覆盖了自定义的函数[^1]。解决这个问题的方法是在自定义的onShareAppMessage函数中调用uni.onShareAppMessage方法，而不是直接覆盖它。以下是一个示例代码：

onShareAppMessage: function() {
  // 在自定义的onShareAppMessage函数中调用uni.onShareAppMessage方法
  return uni.onShareAppMessage();
}

这样做可以确保调用系统的onShareAppMessage方法，从而解决"uni.onShareAppMessage is not a function"的错误。
