Chaos Mesh does _NOT_ have the workflow node of the type `HTTPRequest`. This feature is based on `Task` node, and you can send HTTP requests more conveniently by using the feature.

## Create an HTTP request through Chaos Dashboard
|
|
|
|
You can create an HTTP request in Chaos Dashboard as the following steps that take sending a message through Slack Webhook as an example.
|
|
|
|
### Step 1. Create a workflow node with the type `HTTPRequest`
|
|
|
|
Select "HTTP Request" as the task type:
|
|
|
|
|
|
|
|
### Step 2. Configure an HTTP request
|
|
|
|
Configure the followings:
|
|
|
|
- node name: `send-slack-message`
|
|
- request URL: `https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX`
|
|
- request method: `POST`
|
|
- request body: `{"text": "Hello, world."}` , then check "For JSON content".
|
|
|
|
|
|
|
|
### Step 3. Submit the workflow node
|
|
|
|
Click the "Submit" button to see the task in the preview window:

## Field description

|
|
|
| Parameter | Type | Description | Default value | Required | Example |
|
|
| --- | --- | --- | --- | --- | --- |
|
|
| Name | string | Name of the workflow node | | Yes | `send-slack-message` |
|
|
| URL | string | URL of an HTTP request | | Yes | `https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX` |
|
|
| Method | string | Method of an HTTP request | | Yes | `POST` |
|
|
| Body | string | Body of an HTTP request | | No | `{"text": "Hello, world."}` |
|
|
| Follow 301/302 Location | boolean | The value of this parameter corresponds to the `-L` parameter of `curl`. | `false` | No | `false` |
|
|
| Json Content | boolean | The parameter appends `Content-Type: application/json` to the header of an HTTP request. | `false` | No | `false` |
|
|
|
|
The value of the `name` field of the generated task node adds the suffix `http-request` to the end of "name".
