Question

我有一个在本地系统中运行的本地mesos设置（playa mesos）。我有一个要求，我需要分析来自不同从站的资源，还需要从mesos集群节点（主站和从站）获取调度信息。

我正在尝试使用curl来访问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

返回来自不同奴隶的产品。现在有许多与端点，作业执行等相关的HTTP端点无法正常工作。当我尝试使用curl访问它们时，它根本不工作并且不返回任何json数据。

我需要帮助才能为所有可用的resurces制作mesos http端点。我正在尝试关注mesos文档，但没有运气。如果有人可以发布示例curl命令工作，那将会很棒。谢谢

我相信你的卷曲命令会打击＆＃34; / health＆＃34;端点工作正常;你在命令行看不到任何东西，因为200 OK响应没有正文。要查看响应标头，请使用curl的-i选项：

~/src/mesos/build|master⚡  curl -i --header "Content-Type: application/json" --header "Accept: application/json" -X GET localhost:5050/master/health
HTTP/1.1 200 OK

Content-Length: 0

~/src/mesos/build|master⚡  curl -i --header "Content-Type: application/json" --header "Accept: application/json" -X GET localhost:5050/master/state
HTTP/1.1 200 OK
Date: Wed, 30 Mar 2016 19:16:54 GMT
Content-Type: application/json
Content-Length: 1504
