Discord机器人调用Fortnite Tracker API自定义Header请求失败问题

Let's break down what's going wrong here and how to fix it:

The Core Issue #

You're making a common mistake: you're using the API endpoint URL (r.url) directly as your image source, instead of extracting the actual store image URL from the API's response.

When you send r.url to Discord's embed, Discord's client tries to fetch that URL directly—but it doesn't include your TRN-Api-Key header. That's why you're seeing the "no API key specified" error. The r.url is just the address of the API endpoint, not the image itself.

Corrected Code #

Here's how to properly fetch and use the store image from the API response:

import requests
import discord

# Initialize session with your API key
session = requests.Session()
session.headers.update({'TRN-Api-Key': 'Insert my API Key here'})

# Make the API request
r = session.get('https://api.fortnitetracker.com/v1/store')

# First, check if the request succeeded
if r.status_code == 200:
    # Parse the JSON response from the API
    store_data = r.json()
    # Extract the store image URL (adjust the key if needed—check the API docs for exact field name)
    # From Fortnite Tracker's docs, the store image is usually under 'imageUrl' or similar
    image_url = store_data.get('imageUrl')  # Or check nested fields if needed
    
    if image_url:
        embed = discord.Embed()
        embed.set_image(url=image_url)
        await client.say(embed=embed)
    else:
        # Handle case where image URL isn't found in response
        await client.say("Could not find store image URL.")
else:
    # Handle API request errors (e.g., invalid API key, rate limiting)
    await client.say(f"API Request failed with status code: {r.status_code}")

Key Fixes Explained #

• Parse the API Response: The Fortnite Tracker API returns JSON data containing the store details (including the image URL). Use r.json() to turn that response into a Python dictionary you can work with.
• Extract the Correct Image URL: Dig into the parsed JSON to find the actual image URL field (refer to the API docs if you need to confirm the exact key name—common ones are imageUrl or bannerUrl).
• Error Handling: Add checks for successful requests and missing image URLs to avoid silent failures in your bot.

Additional Troubleshooting Tips #

• Double-check that your TRN-Api-Key is valid and hasn't expired.
• If you're still getting API key errors, try sending the header directly in a requests.get call to rule out session issues:

  r = requests.get(
      'https://api.fortnitetracker.com/v1/store',
      headers={'TRN-Api-Key': 'Insert my API Key here'}
  )
  

• Verify the API response structure by printing store_data to the console—this will help you confirm the exact path to the image URL.
