方框oauth2：无效的grant_type参数或缺少参数 [英] Box oauth2: Invalid grant_type parameter or parameter missing
问题描述
我不知道我做错了什么，但是每次我尝试获取令牌时（当然是在用户身份验证之后），结果始终是无效的grant_type参数或缺少参数
I don't know what I do wrong, but everytime I tried to obtain the token (after user authentication of course), the result is always Invalid grant_type parameter or parameter missing
可能与框相关API在获取访问令牌时始终返回无效的grant_type参数
这是我的提琴手结果：
POST https://api.box.com/oauth2/token HTTP/1.1
Host: api.box.com
Content-Length: 157
Expect: 100-continue
Connection: Keep-Alive
grant_type=authorization_code&code=nnqtYcoik7cjtHQYyn3Af8uk4LG3rYYh&client_id=[myclientId]&client_secret=[mysecret]
结果：

即使在curl示例之后也给出了相同的错误。任何帮助将不胜感激。
Even following the curl example gives the same error. Any help would be appreciated.
编辑：尝试使用其他redirect_uri参数，但仍存在相同错误
tried with additional redirect_uri params but still the same error

推荐答案
像Box要求正确的 Content-Type：application / x-www-form-urlencoded 请求标头，以及对参数进行正确的URL编码。似乎同样适用于刷新和撤消请求。
Looks like Box requires a correct Content-Type: application/x-www-form-urlencoded request header in addition to properly URL encoding the parameters. The same seems to apply to refresh and revoke requests.
此外，根据 RFC 6749 ， redirect_uri 仅
必需，如果如第4.1.1节所述，授权请求
中包含 redirect_uri参数，则其值必须相同。
REQUIRED, if the "redirect_uri" parameter was included in the authorization request as described in Section 4.1.1, and their values MUST be identical.
