Discord注册API返回50035(Invalid Form Body)错误，如何修复？

Let's break down what's going wrong here and get your API call working properly.

1. You're Putting Request Body Data in Headers (And Using the Wrong Parameter) #

The biggest issue is that you're passing registration fields like email, password, and username in the headers instead of the request body. Discord's /auth/register endpoint expects these values in a JSON-formatted body, not as HTTP headers.

When you used the data parameter with requests.post(), it encodes the data as application/x-www-form-urlencoded (form data), which doesn't match what Discord's API is expecting. That's exactly why you're getting the Invalid Form Body error (code 50035).

2. Missing Critical Headers & Incorrect Data Types #

Discord's API also requires specific headers to accept your request, and some fields need the right data type (like consent should be a boolean, not a string).

Corrected Code #

Here's the fixed version of your code with all these issues addressed:

import requests

# Assume these variables are properly defined elsewhere
email = "your_valid_email@example.com"
password = "your_strong_password"
username = "your_desired_username"

# Required headers for Discord API
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36",
    "Content-Type": "application/json"
}

# Registration payload (this goes in the request body, not headers)
payload = {
    "consent": True,  # Use boolean instead of string "true"
    "date_of_birth": "2000-08-05",
    "email": email,
    "password": password,
    "username": username
}

response = requests.post(
    "https://discord.com/api/v9/auth/register",
    headers=headers,
    json=payload  # Use json parameter to send JSON-formatted body
)

print(f"Status Code: {response.status_code}")
print(response.text)

Key Fixes Explained: #

• Moved registration data to payload: This is the correct place for user registration details, not HTTP headers.
• Used json=payload instead of data: This tells requests to send the body as JSON and automatically sets the correct Content-Type (though we explicitly set it too for clarity).
• Fixed consent type: Changed from string "true" to boolean True—Discord's API strictly validates data types for this field.
• Added User-Agent header: Discord blocks requests without a valid user agent (it looks like a bot otherwise). Using a browser-like user agent helps avoid this.

If You Still Get Errors After This: #

Discord's registration process has additional safeguards that might block your request:

• Missing fingerprint: The API often requires a fingerprint field (a unique identifier generated by the Discord client). You can grab this from your browser's developer tools when registering manually.
• CAPTCHA Verification: Discord now requires human verification for most new registrations. Automating this is tricky, as you'd need to integrate a CAPTCHA-solving service (which violates Discord's Terms of Service in most cases).
