# HTTP Client Examples
|
|
|
|
Complete, runnable examples for various languages.
|
|
|
|
## Bash / curl
|
|
|
|
### Complete Script with Auto-Login
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
set -e
|
|
|
|
# Configuration
|
|
BASE_URL="${FLVX_BASE_URL:?FLVX_BASE_URL not set}"
|
|
USERNAME="${FLVX_USERNAME:?FLVX_USERNAME not set}"
|
|
PASSWORD="${FLVX_PASSWORD:?FLVX_PASSWORD not set}"
|
|
|
|
# Login and get token
|
|
echo "Logging in..."
|
|
LOGIN_RESPONSE=$(curl -s -X POST "${BASE_URL}/api/v1/user/login" \
|
|
-H "Content-Type: application/json" \

|
TOKEN=$(echo "$LOGIN_RESPONSE" | jq -r '.data.token // empty')
|
|
|
|
if [ -z "$TOKEN" ]; then
|
|
echo "Login failed: $(echo "$LOGIN_RESPONSE" | jq -r '.msg')"
|
|
exit 1
|
|
fi
|
|
|
|
echo "Logged in successfully"
|

# API call helper
|
|
api_call() {

|
|
local data="${2:-{}}"
|
|

# Examples
|
|
echo "=== My Package Info ==="
|
|
api_call "/api/v1/user/package" | jq '.'
|
|
|
|
echo -e "\n=== Node List ==="
|
|
api_call "/api/v1/node/list" '{}' | jq '.data.list[] | {name, status: (.status == 1)}'

|
|
### Create Forward Script
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
BASE_URL="${FLVX_BASE_URL}"
|
|
TOKEN="${FLVX_TOKEN}" # Pre-obtained token
|
|
|
|
create_forward() {
|
|
local name="$1"
|
|
local tunnel_id="$2"
|
|
local remote_addr="$3"
|
|
|
|
curl -s -X POST "${BASE_URL}/api/v1/forward/create" \
|
|
-H "Authorization: ${TOKEN}" \
|
|
-H "Content-Type: application/json" \
|
|
-d "{
|
|
\"name\": \"${name}\",
|
|
\"tunnelId\": ${tunnel_id},
|
|
\"remoteAddr\": \"${remote_addr}\",
|
|
\"strategy\": \"fifo\"
|
|
}" | jq '.'
|
|
}
|
|
|
|
# Usage: ./create-forward.sh "my-web" 1 "192.168.1.100:80"
|
|
create_forward "$@"
