node.js - 成员必须满足正则表达式模式：[\\S]+

问题描述

我正在尝试在 aws 上执行 lambda 以列出我的 cognito 用户池的用户。这是我在 nodejs 中的代码：

  const queryStringParameters = event.queryStringParameters;
  var paginationToken = '';
  if ( queryStringParameters && queryStringParameters.paginationToken ) {
    paginationToken = queryStringParameters.paginationToken;
  }
  var limit = '10';
  if ( queryStringParameters && queryStringParameters.limit ) {
    limit = queryStringParameters.limit;
  }

  var params = {};
  if ( paginationToken != '' ) {
    params = {
      UserPoolId: userPoolId, /* required */
      //Filter: 'STRING_VALUE',
      Limit: limit,
      PaginationToken: paginationToken
    };
  } else {
    params = {
      UserPoolId: userPoolId, /* required */
      //Filter: 'STRING_VALUE',
      Limit: limit,
      PaginationToken: paginationToken
    };
  }

  cognitoidentityserviceprovider.listUsers(params, function (err, data) {
    if (err) {
      response.code = "ERROR"
      response.message = "Han ocurrido errores"
      response.result = err
      callback(null, {
        statusCode: 500,
        headers,
        body: JSON.stringify(response)
      })
    }
    response.code = "OK"
    response.message = ""
    response.result = data
    callback(null, {
      statusCode: 200,
      headers,
      body: JSON.stringify(response)
    });
  });

我正在使用在其他调用中返回的 paginationToken 在邮递员上测试这个 lambda。返回此错误。

    "message": "Han ocurrido errores",
    "result": {
        "message": "1 validation error detected: Value 'CAISlAIIARLtAQgDEugBAEZixxOnN/v8zMwVa6CHVhw64qYzvU6Iyb5RkRwGsNS eyJAbiI6IlBhZ2luYXRpb25Db250aW51YXRpb25EVE8iLCJuZXh0S2V5IjoiQUFBQUFBQUFCYnYwQVFFQnU0V1pTVlZ1U0FDU1JZODJ4Mk9lL2RxVFRXbVZ3a3RScGVwQXNQT2JTWnBsYm1ZN01ETm1OREk0WVRNdFlqRmxZeTAwT0RZeExUaGpObVF0WkRZeU1ETXlZamd5T1RNek93PT0iLCJwcmV2aW91c1JlcXVlc3RUaW1lIjoxNTY1ODQ1MzU5NTU3fRog0tB4u0ATjZVYBFSGxE llc8AXn2 tEFfFFohzHQmeyY=' at 'paginationToken' failed to satisfy constraint: Member must satisfy regular expression pattern: [\\S]+",

        "retryable": false,
        "retryDelay": 12.077823285760259
    }
}

我正在尝试这个：

解决方案

问题是 PaginationToken 中的加号 (+)。端点接收带有空格而不是加号的令牌，因此简单的替换将修复它。

  PaginationToken = PaginationToken.replace(/\ /g,'+')
