HTTP request component

A component that calls remote services.

An HTTP request component lets you access remote APIs or services by providing a URL and an HTTP method, and then receive the response. You can customize headers, parameters, proxies, and timeout settings, and use common methods like GET and POST. It’s useful for exchanging data with external systems in a workflow.

Prerequisites

An accessible remote API or service.
Add a Token or credentials to the request header, if the target service requires authentication.

Configurations

Url

Required. The complete request address, for example: http://api.example.com/data.

Method

The HTTP request method to select. Available options:

GET
POST
PUT

Timeout

The maximum waiting time for the request, in seconds. Defaults to 60.

Headers

Custom HTTP headers can be set here, for example:

http

{
  "Accept": "application/json",
  "Cache-Control": "no-cache",
  "Connection": "keep-alive"
}

Proxy

Optional. The proxy server address to use for this request.

Clean HTML

Boolean: Whether to remove HTML tags from the returned results and keep plain text only.

Parameter

Optional. Parameters to send with the HTTP request. Supports key-value pairs:

To assign a value using a dynamic system variable, set it as Variable.
To override these dynamic values under certain conditions and use a fixed static value instead, Value is the appropriate choice.

:::tip NOTE

For GET requests, these parameters are appended to the end of the URL.
For POST/PUT requests, they are sent as the request body. :::

Example setting

Example response

html

{ "args": { "App": "RAGFlow", "Query": "How to do?", "Userid": "241ed25a8e1011f0b979424ebc5b108b" }, "headers": { "Accept": "/", "Accept-Encoding": "gzip, deflate, br, zstd", "Cache-Control": "no-cache", "Host": "httpbin.org", "User-Agent": "python-requests/2.32.2", "X-Amzn-Trace-Id": "Root=1-68c9210c-5aab9088580c130a2f065523" }, "origin": "185.36.193.38", "url": "https://httpbin.org/get?Userid=241ed25a8e1011f0b979424ebc5b108b&App=RAGFlow&Query=How+to+do%3F" }

Output

The global variable name for the output of the HTTP request component, which can be referenced by other components in the workflow.

Result: string The response returned by the remote service.

Example

This is a usage example: a workflow sends a GET request from the Begin component to https://httpbin.org/get via the HTTP Request_0 component, passes parameters to the server, and finally outputs the result through the Message_0 component.
