这是一个 JavaScript 错误,指出在解析某个对象时,该对象未定义,因此无法读取其 gender 属性。由于错误信息中提供的代码片段不完整,很难确定问题的确切来源。但是,您可以尝试检查您的代码是否在访问对象之前正确地定义了它,或者检查对象的属性是否正确地命名和定义。此外,您还可以检查您的代码中是否存在其他语法错误或逻辑错误。如果您能提供更多上下文信息或代码示例,我将尽力帮助您解决问题。

这是一个 JavaScript 的错误信息,具体错误信息是 "ReferenceError: FormData is not defined",意思是 "未定义 FormData"。这通常是因为你在代码中使用了 FormData,但是没有引入相关的库或者浏览器不支持 FormData。你需要确认你的代码中是否引入了相关的库,并且在代码中正确使用 FormData。

这段错误信息中的问题与之前类似,是因为在尝试读取一个为 null 的对象的 openid 属性。建议你检查一下代码,确认该对象是否已经被正确地初始化了。你可以使用可选链操作符(?.)来避免出现类似的错误,例如:`const openid = obj?.openid`。或者,在读取对象属性前,先检查一下该对象是否为 null,例如:
```
if (obj !== null && obj.openid) {
// 这里执行读取 openid 属性的逻辑
}
```
另外,你也可以在全局的 `globalData` 对象中定义一个默认的 `openid` 值,例如:
```
App({
globalData: {
openid: null,
user: {}
},
onLaunch: function () {
// ...
}
})
```
这样,在其他地方使用 `getApp().globalData.openid` 时,如果 `openid` 还没有被初始化,就会返回 `null`,而不是抛出 TypeError 异常。
