如何访问mesos http端点以获取集群信息

我有本地系统中运行的本地mesos设置（playa mesos）。我有一个需求，我需要分析来自不同从站的资源提供，还需要从mesos群集节点（主站和从站）获取调度信息。如何访问mesos http端点以获取集群信息

我正在尝试使用curl打击mesos文档中提到的HTTP端点并尝试获取信息。

curl --no-buffer -X POST -H "Content-Type: application/json" --data '{"type":"SUBSCRIBE","subscribe":{"framework_info":{"user":"root","name":"democurl"}}}' http://<ip address>:5050/master/api/v1/scheduler

这是返回来自不同奴隶的产品。现在有很多HTTP端点与调度，作业执行等无关。当我试图用curl访问它们时，它根本无法工作，也没有返回任何json数据。

我需要帮助来制作所有可用的resurces的mesos http端点woking。我正在尝试关注mesos文档，但没有运气。如果有人能发布示例curl命令，它将会很棒。谢谢

你找哪家HTTP状态代码（2XX，3XX，4XX，5XX）？我只是在0.28 Mesos集群上试过你的curl命令，它工作正常。 –

等等，现在这是两个完全不同的问题。 IDK什么是Java的问题是没有上下文，但在/健康的情况下，这是预期的行为 - 返回200，请阅读文档：http://mesos.apache.org/documentation/latest/endpoints/master/health/ –

从java代码尝试时，我得到的一般是4XX。但“curl -header”Content-Type：application/json“--header”Accept：application/json“：5050/master/health”; url只是没有返回任何命令提示符。 – psaha4

我相信你的curl命令击中“/健康”端点工作正常;您在命令行中看不到任何内容，因为200 OK响应没有任何内容。要查看响应头为好，使用-i选项，卷曲：

~/src/mesos/build|master⚡ curl -i --header "Content-Type: application/json" --header "Accept: application/json" -X GET localhost:5050/master/health
