请帮助我。最近,我在处理Chrome扩展时遇到了同样的问题。测试时,调用不会被触发。在我读完这篇文章之前:
要测试这些调用中的任何一个,您必须让您的文件在Web服务器上运行,因为Flash player限制本地文件和internet之间的调用

您可能需要阅读@格肖恩·巴拉斯写了这封信,也许能帮上忙。听起来他已经走过这条路了。@bean5谢谢你的评论。我查过了。但是,我的情况是在Chrome扩展上解决的。我认为许可是问题的核心。我找不到关于Chrome扩展的youtube api权限。您可能想阅读@格肖恩·巴拉斯写了这封信,也许能帮上忙。听起来他已经走过这条路了。@bean5谢谢你的评论。我查过了。但是,我的情况是在Chrome扩展上解决的。我认为许可是问题的核心。我找不到youtube api对Chrome扩展的许可。
