错误响应：使用 AWS SES、Lambda、网关时“JSON 中位置 1 出现意外的令牌 o”

Question

真的不知道如何解决以下错误。当用户通过我的网站提交联系我们表单页面提交时，我尝试返回更详细的响应。

{
  "errorType": "SyntaxError",
  "errorMessage": "Unexpected token o in JSON at position 1",
  "trace": [
    "SyntaxError: Unexpected token o in JSON at position 1",
    "    at JSON.parse (<anonymous>)",
    "    at Runtime.exports.handler (/var/task/index.js:6:53)",
    "    at Runtime.handleOnceNonStreaming (/var/runtime/Runtime.js:74:25)"
  ]
}

Lambda 函数如下：

const aws = require("aws-sdk");
const ses = new aws.SES({ region: "us-east-1" });
exports.handler = async function (event) {
  console.log('EVENT: ', event)
    // Extract the properties from the event body
  const { senderEmail, senderName, message } = JSON.parse(event.body)
  const params = {
    Destination: {
      ToAddresses: ["[email protected]"],
    },
        // Interpolate the data in the strings to send
    Message: {
      Body: {
        Text: { 
            Data: `You just got a message from ${senderName} - ${senderEmail}:
            ${message}` 
        },
      },
      Subject: { Data: `Message from ${senderName}` },
    },
    Source: "[email protected]",
  };

  return ses.sendEmail(params).promise();
};

我遇到了同样的问题，并通过从事件主体中删除

JSON.parse

来解决它。看起来

event

负载会自动从 JSON 解析为 JS 对象。

const { senderEmail, senderName, message } = event.body

或

const { senderEmail, senderName, message } = JSON.parse(JSON.stringify(event.body))

希望有帮助。

附注我正在使用

node 16.x

运行时
