Base64 字符串检查正常。我能够将其导出到另一个网站并再次下载它作为我的图像。当我尝试使用 Drive Javascript api 进行更新时，它只是不断返回此错误：

Invalidvaluefor:Notavalidbase64bytestring

我也确实使字符串 URL 安全。根据此页面 https://google-api-client-libraries.appspot.com/documentation/drive/v2/python/latest/drive_v2.files.html

我在这里做错了吗，文档说发送 Base64，字符串是有效的，并且字符串在整个过程中是完整的，但谷歌不会接受它？

我正在使用 javascript api，我认为使用 javascript api 发送缩略图可能存在错误。

这是请求

我遇到了这个确切的问题并挣扎了一段时间。似乎驱动器 API 不喜欢标准的 base64 格式，因为它不是 url 安全的（包含 '+'、'/' 和 '='）。

当使用 encodeURIComponent() 进行 url 编码时，它似乎也不喜欢 base64 字符串。

但是，它将接受Base64 的 base64url 格式。两者的唯一区别是，'+' 字符被替换为'-'，'/' 字符被替换为'_'。

当我像这样转换字符串时，我能够成功上传缩略图：

var rawBase64 = "iVBORw0KGgoAAAANSUh...UVORK5CYII="; // your raw base64
var data = rawBase64.replace(/\+/g, '-').replace(/\//g, '_');

希望这对其他人有帮助。驱动器文档对如何格式化字符串不是很清楚。
