nodejs https 狀態 200 但正文響應 null, ajax 調用有效但返回錯誤狀態 0

[英]nodejs https status 200 but body response null, ajax call works but returning error status 0

我正在使用 aws 文檔中的代碼在 static 站點上實現聯系表單。 當我測試nodejs lambda function 它是成功的,但返回的結果是null

API 網關中的 POST 測試結果相同。 它返回:

HTTP 狀態:200
響應正文:null

對於方法執行它說Models: application/json => Empty 有問題嗎? 如果是這樣,我不確定要更改什么。

var AWS = require('aws-sdk');
var ses = new AWS.SES();

var RECEIVER = 'name@example.com';
var SENDER = 'name@example.com';

var response = {
 "isBase64Encoded": false,
 "headers": { 'Content-Type': 'application/json', 'Access-Control-Allow-Origin': 'example.com'},
 "statusCode": 200,
 "body": "{\"result\": \"Success.\"}"
 };

exports.handler = function (event, context) {
    console.log('Received event:', event);
    sendEmail(event, function (err, data) {
        context.done(err, null);
    });
};

function sendEmail (event, done) {
    var params = {
        Destination: {
            ToAddresses: [
                RECEIVER
            ]
        },
        Message: {
            Body: {
                Text: {
                    Data: 'name: ' + event.name + '\nphone: ' + event.phone + '\nemail: ' + event.email + '\nnote: ' + event.note,
                    Charset: 'UTF-8'
                }
            },
            Subject: {
                Data: 'Website Contact Form: ' + event.name,
                Charset: 'UTF-8'
            }
        },
        Source: SENDER
    };
    ses.sendEmail(params, done);
}

From the html side, the contact form works as expected when I run the script (an email is delivered to my inbox with name, email, and message) but the ajax request returns an error status 0 HTTP Error: 0

function submitToAPI(e) {
       e.preventDefault();
       var URL = "https://Restful API URL";

            var name = /[A-Za-z]{1}[A-Za-z]/;
            if (!name.test($("#name-input").val())) {
                         alert ("Name cannot be less than 2 characters");
                return;

            var email = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,6})?$/;
            if (!email.test($("#email-input").val())) {
                alert ("Please enter valid email address");
                return;
            }

       var name = $("#name-input").val();
       var email = $("#email-input").val();
       var note= $("#note-input").val();
       var data = {
          name : name,
          email : email,
          note: note
        };

       $.ajax({
         type: "POST",
         url : "https://Restful API URL",
         dataType: "json",
         crossDomain: "true",
         contentType: "application/json; charset=utf-8",
         data: JSON.stringify(data),


         success: function () {
           alert("Thank you!");
           document.getElementById("contact-form").reset();
       location.reload();
         },
         error: function (response) {
           alert("HTTP Error: " + response.status);
           document.getElementById("contact-form").reset();
       location.reload();
         }});
     }

我在這里搜索了論壇並嘗試刪除dataType: "json"並且還檢查了 CORS 已啟用。 都沒有修好。 我被困住了。 誰能指出我正確的方向?

在我看來,您是在告訴您的 lambda 在回調中返回null 您可以改為返回您的響應變量:

exports.handler = function (event, context) {
    console.log('Received event:', event);
    sendEmail(event, function (err, data) {
        context.done(err, response); // <--- change null to response
    });
};
