ejabberd - Ejabberd Rest-api - Rest-API 调用上的 JSON 输入无效
问题描述
我正在 Windows 10 上设置 ejabberd-19.02 服务器，将其配置为通过 rest-api 调用管理命令。我已按照ejabberd-doc中的文档进行操作。我还能够生成 oauth 令牌。
http://localhost:5443/oauth/authorization_token?access_token=0GXCPVJa0l3jFH3Yrn9dIZFMftrNTBFa&token_type=bearer&expires_in=31536000&scope=ejabberd:admin&state=
但是在调用 rest-api 方法时，使用 curl 命令，如文档中所示：
curl -v -X POST -H "X-Admin: true" -H "Authorization: Bearer 0GXCPVJa0l3jFH3Yrn9dIZFMftrNTBFa" http://localhost:5443/api/get_roster -d '{"user": "anas", "server": "localhost"}'
我收到以下消息：
Note: Unnecessary use of -X or --request, POST is already inferred.

解决方案
您尝试提供 JSON 数据，但如您所见，curl 仅发送 7 个字节的内容。7 个字节只有 7 个字符，看这个例子：
$ curl -v -X POST -H "X-Admin: true" -H "Authorization: Bearer UsGV4Ap1zHaaNxJNLiYncn9QG5TRXfEW" http://localhost:5443/api/get_roster -d '{"abcde'
.....
> Content-Length: 7
> Content-Type: application/x-www-form-urlencoded
>
* upload completely sent off: 7 out of 7 bytes
....
所以你用来运行curl的控制台或程序肯定有问题，导致命令行被截断。如您所见，在此示例中，一个好的 JSON 数据需要 40 个字节（在我的情况下，问题是我没有设置管理员权限）：
$ curl -v -X POST -H "X-Admin: true" -H "Authorization: Bearer UsGV4Ap1zHaaNxJNLiYncn9QG5TRXfEW" http://localhost:5443/api/get_roster -d '{"user": "user1", "server": "localhost"}'
Note: Unnecessary use of -X or --request, POST is already inferred.
