如何在Nexmo用户验证API中禁用文本转语音功能？

Hey there! To turn off the text-to-speech (TTS) fallback in your Nexmo Verify API request, you just need to specify a workflow ID that limits verification to SMS only. Let's adjust your code to make that happen:

Modified Code #

const nexmo = require("./nexmo");
let requestId = null; // Switched to let since we're reassigning this value
module.exports = function sendVerificationCode( recipient ) {
  return new Promise((resolve, reject) => {
    nexmo.verify.request({ 
      number: recipient, 
      brand: 'Verification',
      workflow_id: 1 // This forces SMS-only verification, disabling TTS entirely
    }, function(err, result) {
      if (err) {
        return reject(err); // Properly reject the Promise when an error occurs
      }
      if (result.status === 0) {
        requestId = result.request_id;
        resolve(requestId); // Resolve with the request ID on success
      } else {
        reject(new Error(`Verification request failed: ${result.error_text}`));
      }
    });
  });
};

Key Changes Explained #

• workflow_id: 1: This parameter tells the Nexmo Verify API to use the SMS-only workflow. By default, the API might fall back to TTS if SMS delivery hits issues, but setting this ID ensures only SMS is used—completely disabling the text-to-speech mechanism.
• Fixed Promise Handling: I updated your Promise logic to properly resolve on success and reject when errors occur or the request returns a non-zero status code. Your original code wasn't triggering these, which could lead to unhandled Promise states.

Quick Workflow ID Reference (For Future Use) #

If you ever need to switch verification methods later, here are the common workflow IDs:

• 1: SMS only (what you need now)
• 2: TTS only
• 3: SMS first, then TTS after a delay
• 4: TTS first, then SMS after a delay
