TypError when calling an API from a lambda function

问题

I need to call an API from my lambda function to send an OTP and for that for the path I need to pass some query strings so I do as shown below.

  1. const https = require('https');
  3. function postRequest(body) {
  4.   
  5.   const ans = body.answer
  6.   const phon = body.phone
  7.   
  8.   const options = {
  9.     hostname: 'app.xxx.xx',
  10.     path: '/api/v1/send?user_id=24xxx&api_key=3Yxxxx&sender_id=dEMO&to=' + phon + '&message=Your%OTP%is%' + ans + 'thanks',
  11.     method: 'POST',
  12.     port: 443,
  13.   };
  15.   return new Promise((resolve, reject) => {
  16.     const req = https.request(options, res => {
  17.       let rawData = '';
  19.       res.on('data', chunk => {
  20.         rawData += chunk;
  21.       });
  23.       res.on('end', () => {
  24.         try {
  25.           resolve(JSON.parse(rawData));
  26.         } catch (err) {
  27.           reject(new Error(err));
  28.         }
  29.       });
  30.     });
  32.     req.on('error', err => {
  33.       reject(new Error(err));
  34.     });
  36.     req.write(JSON.stringify(body));
  37.     req.end();
  38.   });
  39. }
  41. exports.handler = async (event, context, callback) => {
  42.   // Create a random number for OTP
  43.   const challengeAnswer = Math.random().toString(10).substr(2, 4);
  44.   const phoneNumber = event.request.userAttributes.phone_number;
  46.   console.log(event, context);
  47.  
  48.   await postRequest({
  49.       phone: phoneNumber,
  50.       answer: challengeAnswer,
  51.     },
  52.     function(err, data) {
  53.       if (err) {
  54.         console.log(err.stack);
  55.         console.log(data);
  56.         return;
  57.       }
  58.       console.log(`SMS sent to ${phoneNumber} and OTP = ${challengeAnswer}`);
  59.       return data;
  60.     });
  62.   callback(null, event);
  63. };

But when I do so I get this error,
'TypeError [ERR_UNESCAPED_CHARACTERS]: Request path contains unescaped characters'
How to fix this?

得分: 1

Here is the translated code snippet:

  1. 你可以尝试将以下代码部分替换为安全的 URL 格式：
  2. ```js
  3. const { phone, answer } = body;
  5. const options = {
  6.   hostname: 'app.xxx.xx',
  7.   path: encodeURI(`/api/v1/send?user_id=24xxx&api_key=3Yxxxx&sender_id=dEMO&to=${phone}&message=Your%OTP%is%${answer}thanks`),
  8.   method: 'POST',
  9.   port: 443,
  10. };

你也可以尝试对整个 options 对象进行 JSON.stringify() 处理，但需要确保你的 API 能够接受 JSON 格式的数据。

  2. <details>
  3. <summary>英文:</summary>
  4. You may try to replace:
  5. ```js
  6. const ans = body.answer
  7. const phon = body.phone
  8. const options = {
  9. hostname: &#39;app.xxx.xx&#39;,
  10. path: &#39;/api/v1/send?user_id=24xxx&amp;api_key=3Yxxxx&amp;sender_id=dEMO&amp;to=&#39;+{phon}+&#39;&amp;message=Your%OTP%is%&#39;+{ans}+&#39;thanks&#39;,
  11. method: &#39;POST&#39;,
  12. port: 443,
  13. };

By:

  1. const { phone, answer } = body;
  2.   
  3. const options = {
  4.   hostname: &#39;app.xxx.xx&#39;,
  5.   path: encodeURI(`/api/v1/send?user_id=24xxx&amp;api_key=3Yxxxx&amp;sender_id=dEMO&amp;to=${phone}&amp;message=Your%OTP%is%${answer}thanks`),
  6.   method: &#39;POST&#39;,
  7.   port: 443,
  8. };

in order to have an url safe format.
You may also try to JSON.stringify() the whole options object, but it will need to ensure your API can consume JSON.
