HTTP API

SRS provides HTTP api, to external application to manage SRS, and support crossdomain for js.

Once HTTP API enabled, you can use srs-console to connect to your SRS server.

Design Priciple

The HTTP API of SRS follows the simple priciple:

• Only provides API in json format, both request and json are json.
• Please use srs-console to access API.
• When error, response in HTTP status or code in json.

Build

SRS always enable the http api, read configure

./configure && make

Config

The config also need to enable it:

listen              1935;
# system statistics section.
# the main cycle will retrieve the system stat,
# for example, the cpu/mem/network/disk-io data,
# the http api, for instance, /api/v1/summaries will show these data.
# @remark the heartbeat depends on the network,
#       for example, the eth0 maybe the device which index is 0.
stats {
    # the index of device ip.
    # we may retrieve more than one network device.
    # default: 0
    network         0;
    # the device name to stat the disk iops.
    # ignore the device of /proc/diskstats if not configed.
    disk            sda sdb xvda xvdb;
}
# api of srs.
# the http api config, export for external program to manage srs.
# user can access http api of srs in browser directly, for instance, to access by:
#       curl http://192.168.1.170:1985/api/v1/reload
# which will reload srs, like cmd killall -1 srs, but the js can also invoke the http api,
# where the cli can only be used in shell/terminate.
http_api {
    # whether http api is enabled.
    # default: off
    enabled         on;
    # the http api listen entry is <[ip:]port>
    # for example, 192.168.1.100:1985
    # where the ip is optional, default to 0.0.0.0, that is 1985 equals to 0.0.0.0:1985
    # default: 1985
    listen          1985;
    # whether enable crossdomain request.
    # default: on
    crossdomain     on;
    # the HTTP RAW API is more powerful api to change srs state and reload.
    raw_api {
        # whether enable the HTTP RAW API.
        # default: off
        enabled             off;
        # whether enable rpc reload.
        # default: off
        allow_reload        off;
        # whether enable rpc query.
        # default: off
        allow_query         off;
        # whether enable rpc update.
        # default: off
        allow_update        off;
    }
}
vhost __defaultVhost__ {
}

The http_api enable the HTTP API, and stats used for SRS to stat the system info, including:

• network: Used for heartbeat to report the network info, where heartbeat used to report system info. Please read Heartbeat
• disk: Used to stat the specified disk iops. You can use command cat /proc/diskstats to get the right disk names, for instance, xvda.

Start

Start SRS: ./objs/srs -c http-api.conf

Access api, open the url in web browser: http://192.168.1.170:1985/api/v1

Remark: Please use your server ip instead.

Performance

The HTTP api supports 370 request per seconds.

Access Api

Use web brower, or curl, or other http library.

SRS provides api urls list, no need to remember:

• code, an int error code. 0 is success.
• urls, the url lists, can be access.
• data, the last level api serve data.

Root directory:

# curl http://192.168.1.102:1985/
    "urls": {
        "api": "the api root"
    }

The urls is the apis to access:

# curl http://192.168.1.102:1985/api/
    "urls": {
        "v1": "the api version 1.0"
    }

Go on:

# curl http://192.168.1.102:1985/api/v1/
    "urls": {
        "versions": "the version of SRS",
        "authors": "the primary authors and contributors"
    }

Go on:

# curl http://192.168.1.102:1985/api/v1/versions
        "major": 0,
        "minor": 9,
        "revision": 43,
        "version": "0.9.43"

Or:

# curl http://192.168.1.102:1985/api/v1/authors
        "primary_authors": "winlin,wenjie.zhao",
        "contributors_link": "https://github.com/ossrs/srs/blob/master/AUTHORS.txt",
        "contributors": "winlin<[email protected]> wenjie.zhao<[email protected]> xiangcheng.liu<[email protected]> naijia.liu<[email protected]> alcoholyi<[email protected]> "

The Api of SRS is self-describes api.

Error Code

SRS response error in both HTTP status or HTTP body.

For example, SRS response HTTP error, where HTTP status not 200:

winlin:~ winlin$ curl -v http://127.0.0.1:1985 && echo ""
< HTTP/1.1 404 Not Found
< Connection: Keep-Alive
< Content-Length: 9
< Content-Type: text/plain; charset=utf-8
< Server: SRS/2.0.184
< 
Not Found

For example, SRS response code not 0 when HTTTP Status 200:

winlin:~ winlin$ curl -v http://127.0.0.1:1985/api/v1/tests/errors && echo ""
< HTTP/1.1 200 OK
< Connection: Keep-Alive
< Content-Length: 12
< Content-Type: application/json
< Server: SRS/2.0.184
< 
{"code":100}

User should handle these two error style.

Crossdomain

SRS HTTP API supports js crossdomain, so the html/js can invoke http api of srs。

SRS support two main CROS styles:

• OPTIONS: JQuery can directly access the CROS, where the brower will send an OPTIONS first, then the API request.
• JSONP: JQuery/Angularjs can send JSONP CROS request to SRS API, where specifes the function name by QueryString callback.
• JSONP-DELETE: JSONP only support GET, so we use the method in QueryString to override the HTTP method for JSONP.

For example, the JSONP crossdomain request:

GET http://localhost:1985/api/v1/vhosts/?callback=JSON_CALLBACK
JSON_CALLBACK({"code":0,"server":13449})
GET http://localhost:1985/api/v1/vhosts/100?callback=JSON_CALLBACK&method=DELETE
JSON_CALLBACK({"code":0})

Server ID

Each response of api contains a server field, which identify the server. When ServerID changed, SRS already restarted, all information before is invalid.

API Nevigation

SRS provides the nevigation of APIs.

User can access the http://192.168.1.102:1985/api/v1, where:

API	Example	Description
server	4481	The identity of SRS

User can get the system summaries, for instance, the memory, cpu, network, load usage.

Please access the url http://192.168.1.170:1985/api/v1/summaries

Vhosts

SRS provides http api to query all vhosts.

The http api vhost url: http://192.168.1.102:1985/api/v1/vhosts

To process specified vhost by id, for instance http://192.168.1.102:1985/api/v1/vhosts/3756

Streams

SRS provides http api to query all streams.

The http api stream url: http://192.168.1.102:1985/api/v1/streams

To process specified stream by id, for instance http://192.168.1.102:1985/api/v1/streams/3756

Clients

SRS provides http api to query clients, default to get top 10 clients.

The http api client url: http://192.168.1.102:1985/api/v1/clients

To process specified client by id, for instance http://192.168.1.102:1985/api/v1/clients/3756

Kickoff Client

SRS provides HTTP RESTful api to kickoff user:

DELETE /api/v1/clients/{id}

User can get the id of client to kickoff:

GET /api/v1/clients

User can get the id of publish client from streams api:

GET /api/v1/streams
or GET /api/v1/streams/6745

The client cid is the info from stream api stream.publish.cid:

1. GET http://192.168.1.170:1985/api/v1/streams/6745
2. Response stream.publish.cid:
stream: {
    publish: {
        active: true,
        cid: 107
    }
}
3. DELETE http://192.168.1.170:1985/api/v1/clients/107

Remark: User can use HTTP REST Tool to send a request.

Remark: User can use linux tool curl to start HTTP request. For example:

curl -v -X GET http://192.168.1.170:1985/api/v1/clients/426 && echo ""
curl -v -X DELETE http://192.168.1.170:1985/api/v1/clients/426 && echo ""

Persistence Config

HTTP RAW API will reload and persistence config to file.

1. To reformat config without comments.
2. To support HTTP RAW API, please read HTTP RAW API.

Remark: Signal SIGUSR1 used for Log Rotate, not for persistence config anymore.

The config persistence file maybe:

listen 1935;
max_connections 1000;
daemon off;
srs_log_tank console;
pithy_print_ms 1000;
http_api {
    enabled on;
    listen 1985;
}
http_server {
    enabled on;
    listen 8080;
}
stream_caster {
    enabled off;
    caster flv;
    output rtmp://127.0.0.1/[app]/[stream];
    listen 8936;
}
vhost __defaultVhost__ {
    ingest livestream {
        enabled on;
        input {
            type file;
            url doc/source.200kbps.768x320.flv;
        }
        ffmpeg ./objs/ffmpeg/bin/ffmpeg;
        engine {
            enabled off;
            output rtmp://127.0.0.1:[port]/live?vhost=[vhost]/livestream;
        }
    }
    http_remux {
        enabled off;
        mount [vhost]/[app]/[stream].flv;
        hstrs on;
    }
}

HTTP RAW API

SRS supports powerful HTTP RAW API, while other server only support Read API, for instance, to get the stat of server. SRS supports Write API, which can Reload or change server state.

Remark: User must enable the HTTP RAW API, in config section http_api to enable the http_api.raw_api.enabled, or SRS will response error code 1061.

http_api {
    enabled         on;
    listen          1985;
    raw_api {
        enabled             on;
        allow_reload        on;
        allow_query         on;
        allow_update        on;
    }
}
