Node.js &引用；无效的\u请求。。。缺少授权类型“；当从NodeJs调用某些OAuth2而不是从具有完全相同头的curl调用时

我非常困惑，为什么从NodeJs节点rest客户端调用它时，从springsecurityoauth2得到“missingsgranttype”错误

我通过“嗅探器”检查，我可以看到我发布的标题和正文完全相同。我注意到的唯一区别是“Content-Type:application/x-www-form-urlencoded”在从NodeJs调用时不是settup，但据我所知，node-rest客户端不允许这样做。我不认为这会产生影响，因为我可以看到“grant_type=password&username=a&password=a”的格式与curl中的格式完全相同

据我所知，在curl中，“-u greencard trusted client:greencard secret”意味着我传递它的抛出头和“-d”grant_type=password&username=a&password=a”作为主体，因此，我理解我使用节点rest客户端的方式与下面使用curl的方式相同

如有任何建议，将不胜感激

curl-u myapp可信客户端：myapp secret-k-d“grant_type=password&username=a&password=a”-H“内容类型：application/x-www-form-urlencoded”

我认为您应该在值

application/x-www-form-urlencoded

中添加标题

Content Type

。您是对的。刚刚修好了。请留下您的评论作为答案，然后我会选择它作为答案。我认为您应该在

应用程序/x-www-form-urlencoded

的值中添加标题
