为什么我的JSON没有直接从客户端转移到服务器端

标签: json node.js mongodb

我有以下JSON:

{
  "fields":[
    {"name":"thom","techname":"rgom","description":"dfgkjd","type":"text"},
    {"name":"thom","techname":"rgom2","description":"dfgkjd","type":"text"}
   ]
}

当我使用此代码将其发布到NodeJS服务器时:

    $.ajax({ 
      data : data, 
      type: 'POST',
      dataType: 'json',
      timeout: 10000,         
      url : '/schema/create', 
      success : function(response) {
        console.log(response)
      },
      complete : function() {
      },
      error: function(x, t, m) {
        if(t==="timeout") {
          alert("Timeout");
        } else {
          alert("Der opstod følgende fejl:" + t + x + m + ". Kontakt COWI");
        }
      }

    });

然后插入:

db.collection('schemas').insert(fields, {upsert:true}, function(err, result) {
  if(!err){
    console.log("written");
    console.log(result);

  }
});

在MongoDB中我有:

"_id" : ObjectId("5512ed12ecacf6e01da7aaa4"),
"fields[0][name]" : "thom",
"fields[0][techname]" : "rgom",
"fields[0][description]" : "dfgkjd",
"fields[0][type]" : "text",
"fields[1][name]" : "thom",
"fields[1][techname]" : "rgom2",
"fields[1][description]" : "dfgkjd",
"fields[1][type]" : "text"

我在期待:

{
  "_id":ObjectId("5512ed12ecacf6e01da7aaa4"),
  "fields":
  [
    {
      "name":"thom", 
      "techname" : "rgom",
      "description" : "dfgkjd",
      "type" : "text"
    },
    {
      "name":"thom", 
      "techname" : "rgom2",
      "description" : "dfgkjd",
      "type" : "text"
    }
  ]
}

修改 在插入之前记录:

[ { 'fields[0][name]': 'thom',
    'fields[0][techname]': 'rgom',
    'fields[0][description]': 'dfgkjd',
    'fields[0][type]': 'text',
    'fields[1][name]': 'thom',
    'fields[1][techname]': 'rgom2',
    'fields[1][description]': 'dfgkjd',
    'fields[1][type]': 'text',
    _id: 5512ed12ecacf6e01da7aaa4 } ]

编辑2 在插入之前记录控制台(使用JSON.stringify()):

{
        "_id" : ObjectId("5512f0d4606391f41ddd16d1"),
        "{"fields":[{"name":"sdkljg","techname":"fgklj","description":"dfgklj","
type":"text"}]}" : ""
}

在db插入之前记录fields时获得的格式表示您将数据作为params从客户端发送到服务器。如果这样做,您必须手动将其转换回要插入mongodb的对象。如果您只是将其作为json字符串发送,那么您就不必在服务器端进行转换。

data: JSON.stringify(data),
contentType: 'application/json'
