Background Worker Pool

BWP can handle different jobs and proceed them in the background. This will be useful when you need to execute long-time request from php or any other fast context without possibility of waiting for a response.

Features:

  • Job http -- Execute http request.
  • Setup IP from which http requests will be sent.
  • Graceful restart from updated binary

Web API

POST /post/http -- Submit new http request

The method accepts raw json content in the request body with the following format:

{
  "url": "https://google.com",
  "method": "GET", // Optional, GET by default
  "body": "base64 encoded raw body", // Optional
  "parameters": { // Optional, on GET or HEAD this will be appended to the url, othervise parameters will be in the POST args
    "foo": "bar"
  },
  "headers": { // Optional, any custom headers
    "X-Auth-Email": "example@example.com",
    "Cookie": "foo=bar"
  }
}

Multiple requests can also be sent at once using an array.

There is another way to send multiple requests:

{
  "method": "POST",
  "body": "eyJoZWxsbyI6IndvcmxkIn0=",
  "headers": {"X-Sender": "me"},
  "clones": [{
    "url": "https://first-secret-domain.com",
    "headers": {"X-Secret": "puppies"}
  }, {
    "url": "https://second-secret-domain.com",
    "headers": {"X-Secret": "kittens"}
  }]
}

As a result of the above request, bwp will send 2 http requests to https://first-secret-domain.com and https://second-secret-domain.com with the same body from the parent request.

GET /metrics -- Prometheus metrics page
