Twilio Studio - 向 API 发出请求时遇到问题

Question

我在使用 Twilio Studio 开发 IVR 时遇到问题。 目前，我需要使用 API 发出一些请求。默认情况下，要发出请求，必须通过身份验证端点，以便生成令牌，以便我可以在其他端点中使用它。我的问题是，如何在新函数中使用生成的令牌以便正确发出请求？

到目前为止，我已经尝试调用在新函数中请求令牌的小部件来验证其他事项，但它返回一个错误，指出无法访问内容。

• Widget Run Function - Authorization_API1 -> 负责生成token的函数。

• Widget Split 基于 - tokenCriado1 -> 负责验证返回是否为“成功”的函数。

• 小部件运行功能 - validaDebito - > 它根据生成的令牌执行新的 API 调用。

我的功能

const axios = require('axios');

exports.handler = function(context, event, callback) {
        
    // Get the CPF/CNPJ from the event
    const cpfCnpj = event.CPF_CNPJ;

    // Check if the CPF/CNPJ was provided
    if (!cpfCnpj) {
        return callback("CPF/CNPJ not provided.");
    }

    // Get the token generated by the Authorization_API1 widget
    const token = event.widgets.Authorization_API1.parsed.token;

    // Check if the token was provided
    if (!token) {
        return callback("Authorization token not provided.");
    }

    // Base URL of the endpoint
    const baseUrl = 'https://app.omnilink.com.br/apigateway/getcliente';

    // Complete URL with the 'CPF_CNPJ' parameter
    const endpointUrl = `${baseUrl}?CPF_CNPJ=${cpfCnpj}`;

    // Make an HTTP request to get the client's data
    axios.get(endpointUrl, {
        headers: {
            Authorization: `Bearer ${token}` // Add the token to the authorization header
        }
    })
    .then(response => {
        // Check if the response was successful
        if (response.status === 200) {
            // Check if ComunicacaoChip and ComunicacaoSatelital are true
            const cliente = response.data.Cliente;
            if (cliente.ComunicacaoChip && cliente.ComunicacaoSatelital) {
                // Client has no debts
                callback(null, { success: true, inadimplente: false });
            } else {
                // Client is in debt
                callback(null, { success: true, inadimplente: true });
            }
        } else {
            // Response was not successful
            callback(`Error in request: ${response.statusText}`);
        }
    })
    .catch(error => {
        // Error making the HTTP request
        callback(`Error obtaining client data: ${error}`);
    });
};

看起来您期望小部件对象自动传递给正在运行的函数。 Twilio 文档 [1] 提供了完整的示例，但您需要在“运行函数”小部件中添加函数参数以将数据传递给函数。

以下配置允许您将解析的令牌从 Authorization_API1 小部件响应传递给函数，该值将根据事件对象上的“token”键设置。

Key: token
Value: {{widgets.Authorization_API1.parsed.token}} 

如果您将 Twilio 函数的第 14 行更新为

const token = event.token

然后您应该能够使用令牌来调用您的 API。
