Twitter OAuth 1.0 请求令牌时出现「215 Bad Authentication Data」错误排查求助

Hey there, sorry to hear you're hitting this frustrating 215 Bad Authentication Data error with Twitter's 3-legged OAuth—let's dive into the most likely fixes based on your setup and the differences between Twitter and LinkedIn's OAuth implementations:

Key Troubleshooting Steps #

• Remove the oauth_token parameter from your request header
  This is probably the biggest issue here. In the 3-legged OAuth flow, the request_token endpoint (first step) should only use your consumer key/secret to request a temporary token for user authorization. You don't need to include an oauth_token here—that parameter is used in later steps (like exchanging the authorized request token for an access token) or for 2-legged app-only auth. Including it here confuses Twitter's OAuth validation logic.

• Switch from GET to POST method
  Twitter's OAuth 1.0a specification requires the request_token request to use the POST method, even though LinkedIn might tolerate GET. Your current setup uses GET, which will cause signature validation to fail because the base string for signing will be incorrect. Update your WebActivity method to POST.

• Fix parameter formatting (for future steps)
  In your current header, you have a space in the oauth_token key-value pair: oauth_token = "<snipped>". OAuth parameters must not have spaces around the equals sign—correct format is oauth_token="<snipped>". While this isn't the main issue right now, it's a critical gotcha to watch for in later flow steps.

• Double-check callback URL exact match
  Twitter requires the oauth_callback value in your request to perfectly match the callback URL configured in your Twitter Developer Portal (including case, trailing slashes, and path details). Even minor mismatches (like unencoded vs encoded URLs between portal and request) will trigger this error. LinkedIn's validation is often more lenient here, making this a common failure point.

• Verify signature generation details
  Even though Postman generates this automatically, confirm:

  • The signature base string includes the correct HTTP method (POST, once updated), fully encoded request URL, and OAuth parameters sorted lexicographically.
  • The signing key is formatted as YOUR_CONSUMER_SECRET& (note the trailing ampersand, with nothing after it—since there's no token secret at the request_token step). If you accidentally included an access token secret here, the signature will be invalid.

• Check your Twitter app's status
  Ensure your app isn't in "Draft" status in the Twitter Developer Portal—draft apps can't make authorized API requests. Also confirm you've enabled OAuth 1.0a in your app's authentication settings.
