Question

使用此代码，我创建了一个创建一些JSON数据并将其发送到server.js（我的节点服务器）的函数。

function deleteEmail(i) {
    emailObj.splice(i, 1);
    var general = {};
    var table = []
    general.table = table;
    for (var i = 0; i < emailObj.length; i++) {
      var dataHtml = emailObj[i].html;
      var html = {
        "html": dataHtml
      }
      general.table.push(html);
    }
    console.log(JSON.stringify(general));
    $.post("email2", general);
  }

server.js中用于捕获JSON数据的代码是：

app.post("/email2", function(req, res){
   console.log(req.body);
});

这是函数创建并发送到server.js的JSON数据：

{"table":[{"html":"<b>ID email:</b> #1481145671503<br><b>Form journey:</b> General<br><b>Work Request Title:</b> <br><b>Data Request:</b> <br><b>Request By:</b> <br><b>Department:</b> <i>not specified</i><br><b>Business Owner:</b> <br><b>Contact Details:</b> <br><b>Request Overview:</b> <br><b>Platform Impacted:</b> undefined<br><b>Business Objectives:</b> <br><b>Business Benefits Justifications:</b> <br><b>Project Drive:</b> <br><b>Additional Information:</b> <br>"},{"html":"<b>ID email:</b> #1481214851188<br><b>Date:</b> Thu Dec 08 2016 16:34:11 GMT+0000 (GMT)<br><b>Form journey:</b> General<br><b>Work Request Title:</b> <br><b>Data Request:</b> <br><b>Request By:</b> <br><b>Department:</b> <i>not specified</i><br><b>Business Owner:</b> <br><b>Contact Details:</b> <br><b>Request Overview:</b> <br><b>Platform Impacted:</b> undefined<br><b>Business Objectives:</b> <br><b>Business Benefits Justifications:</b> <br><b>Project Drive:</b> <br><b>Additional Information:</b> <br>"}]}

这是服务器正在接收的JSON数据：

 { 'table[0][html]': '<b>ID email:</b> #1481145671503<br><b>Form journey:</b> General<br><b>Work Request Title:</b> <br><b>Data Request:</b> <br><b>Request By:</b> <br><b>Department:</b> <i>not specified</i><br><b>Business Owner:</b> <br><b>Contact Details:</b> <br><b>Request Overview:</b> <br><b>Platform Impacted:</b> undefined<br><b>Business Objectives:</b> <br><b>Business Benefits Justifications:</b> <br><b>Project Drive:</b> <br><b>Additional Information:</b> <br>',
  'table[1][html]': '<b>ID email:</b> #1481214851188<br><b>Date:</b> Thu Dec 08 2016 16:34:11 GMT+0000 (GMT)<br><b>Form journey:</b> General<br><b>Work Request Title:</b> <br><b>Data Request:</b> <br><b>Request By:</b> <br><b>Department:</b> <i>not specified</i><br><b>Business Owner:</b> <br><b>Contact Details:</b> <br><b>Request Overview:</b> <br><b>Platform Impacted:</b> undefined<br><b>Business Objectives:</b> <br><b>Business Benefits Justifications:</b> <br><b>Project Drive:</b> <br><b>Additional Information:</b> <br>' }

为什么要这样做？如何在发送时保留完全相同的格式和数据，并通过server.js对其进行解释。

Answer 1

您永远不会将JSON数据发送到服务器。

console.log(JSON.stringify(general));

在上面一行中你：

选择general，一个JavaScript对象
将其转换为JSON
记录

$.post("email2", general);

在上面一行中，您将general（仍然不是JSON！）传递给$.post。

当您传递post个对象时，jQuery会将其转换为application/x-www-form-urlencoded编码数据并发送。

如果您想发送JSON，则需要：

假设您要发送JSON
实际上发送JSON

这样：

$.ajax({
    url: "email2",
    method: "POST",
    data: JSON.stringify(general),
    contentType: "application/json"
});

发送到节点服务器时{J}对象被更改
