json 响应包含 \n \r
我正在客户端使用 ASP.NET 和 jQuery。
我正在使用 Json.NET 序列化服务器端数据库中的数据,并将其发送到当 Ajax 请求到达时客户端。
当我打开 FireBug 时,我看到以下 json:
{"d":"[\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"a\",\r\n \"Description\": \"123\",\r\n \"CategoryType\": \"Personal\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n },\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"b\",\r\n \"Description\": \"bla bla\",\r\n \"CategoryType\": \"Professional\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n },\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"c\",\r\n \"Description\": \"123\",\r\n \"CategoryType\": \"Personal\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n },\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"d\",\r\n \"Description\": \"bla bla\",\r\n \"CategoryType\": \"Professional\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n }\r\n]"}
我的服务器端代码:
[WebMethod]
public static string LoadRatingForm()
{
bll_Trait t1 = new bll_Trait();
t1.TraitID = 1;
t1.TraitName = "a";
t1.Description = "aaa";
bll_Trait t2 = new bll_Trait();
t2.TraitID = 1;
t2.TraitName = "a";
t2.Description = "aaa";
bll_Trait t3 = new bll_Trait();
t3.TraitID = 1;
t3.TraitName = "a";
t3.Description = "aaa";
bll_Trait t4 = new bll_Trait();
t4.TraitID = 1;
t4.TraitName = "a";
t4.Description = "aaa";
bll_Category c1 = new bll_Category();
c1.CategoryID = 1;
c1.CategoryName = "a";
c1.CategoryType = "Personal";
c1.Description = "123";
c1.Traits.Add(t1);
c1.Traits.Add(t2);
bll_Category c2 = new bll_Category();
c2.CategoryID = 1;
c2.CategoryName = "b";
c2.CategoryType = "Professional";
c2.Description = "bla bla";
c2.Traits.Add(t3);
c2.Traits.Add(t4);
bll_Category c3 = new bll_Category();
c3.CategoryID = 1;
c3.CategoryName = "c";
c3.CategoryType = "Personal";
c3.Description = "123";
c3.Traits.Add(t1);
c3.Traits.Add(t2);
bll_Category c4 = new bll_Category();
c4.CategoryID = 1;
c4.CategoryName = "d";
c4.CategoryType = "Professional";
c4.Description = "bla bla";
c4.Traits.Add(t3);
c4.Traits.Add(t4);
List<bll_Category> list = new List<bll_Category>();
list.Add(c1);
list.Add(c2);
list.Add(c3);
list.Add(c4);
return JsonConvert.SerializeObject(list, Formatting.Indented);
}
我的 jQuery 代码:
$.ajax({
type: "POST",
url: "MyProfile.aspx/LoadRatingForm",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var html;
var categories = response.d;
$.each(categories, function (i, category) {
// create
//while (category.CategoryType == "Professional") {
//
//}
html += category.CategoryName + " ";
});
dialog.append(html);
},
error: function () {
alert("ERROR");
}
});
'dialog' 变量是一个 jQuery UI 模式对话框,$.ajax 代码位于对话框的 'open' 事件处理程序中...
我应该怎么做才能使序列化结果成为“正确”的 json 格式,没有任何 '\n'、'\r' 和 '\' ?
提前致谢!
I'm working with ASP.NET and jQuery on client side.
I'm using Json.NET to serialize data from the DB on the server side and I'm sending it to the client when an Ajax request arrives.
When I open FireBug, I see the following json:
{"d":"[\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"a\",\r\n \"Description\": \"123\",\r\n \"CategoryType\": \"Personal\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n },\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"b\",\r\n \"Description\": \"bla bla\",\r\n \"CategoryType\": \"Professional\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n },\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"c\",\r\n \"Description\": \"123\",\r\n \"CategoryType\": \"Personal\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n },\r\n {\r\n \"CategoryID\": 1,\r\n \"CategoryName\": \"d\",\r\n \"Description\": \"bla bla\",\r\n \"CategoryType\": \"Professional\",\r\n \"Traits\": [\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n },\r\n {\r\n \"TraitID\": 1,\r\n \"TraitName\": \"a\",\r\n \"Description\": \"aaa\"\r\n }\r\n ]\r\n }\r\n]"}
My code from server side:
[WebMethod]
public static string LoadRatingForm()
{
bll_Trait t1 = new bll_Trait();
t1.TraitID = 1;
t1.TraitName = "a";
t1.Description = "aaa";
bll_Trait t2 = new bll_Trait();
t2.TraitID = 1;
t2.TraitName = "a";
t2.Description = "aaa";
bll_Trait t3 = new bll_Trait();
t3.TraitID = 1;
t3.TraitName = "a";
t3.Description = "aaa";
bll_Trait t4 = new bll_Trait();
t4.TraitID = 1;
t4.TraitName = "a";
t4.Description = "aaa";
bll_Category c1 = new bll_Category();
c1.CategoryID = 1;
c1.CategoryName = "a";
c1.CategoryType = "Personal";
c1.Description = "123";
c1.Traits.Add(t1);
c1.Traits.Add(t2);
bll_Category c2 = new bll_Category();
c2.CategoryID = 1;
c2.CategoryName = "b";
c2.CategoryType = "Professional";
c2.Description = "bla bla";
c2.Traits.Add(t3);
c2.Traits.Add(t4);
bll_Category c3 = new bll_Category();
c3.CategoryID = 1;
c3.CategoryName = "c";
c3.CategoryType = "Personal";
c3.Description = "123";
c3.Traits.Add(t1);
c3.Traits.Add(t2);
bll_Category c4 = new bll_Category();
c4.CategoryID = 1;
c4.CategoryName = "d";
c4.CategoryType = "Professional";
c4.Description = "bla bla";
c4.Traits.Add(t3);
c4.Traits.Add(t4);
List<bll_Category> list = new List<bll_Category>();
list.Add(c1);
list.Add(c2);
list.Add(c3);
list.Add(c4);
return JsonConvert.SerializeObject(list, Formatting.Indented);
}
My jQuery code:
$.ajax({
type: "POST",
url: "MyProfile.aspx/LoadRatingForm",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var html;
var categories = response.d;
$.each(categories, function (i, category) {
// create
//while (category.CategoryType == "Professional") {
//
//}
html += category.CategoryName + " ";
});
dialog.append(html);
},
error: function () {
alert("ERROR");
}
});
The 'dialog' variable is a jQuery UI modal dialog and the $.ajax code is in the dialog's 'open' event handler...
What should I do to make the serialization result in a "correct" json format without any '\n', '\r' and '\' ?
Thanks in advance!

您可以尝试
return JsonConvert.SerializeObject(list, Formatting.None);
您看过这个相关问题吗ASP.NET+jQuery,如何反序列化 JSON?。可能与 Content-Type 标头有关。
编辑:查看评论,没有解析 JSON。
You could try
return JsonConvert.SerializeObject(list, Formatting.None);
Have you looked at this related question ASP.NET+jQuery, how to deSerialize JSON?. Might be something to do with the Content-Type header.
EDIT: See comments, there was no parsing of the JSON.
根据 JSON 规范:“可以在任何标记对之间插入空格。”
http://www.json.org/
所以不用担心。
或者在此处阅读有关 JSON 格式的信息 http://james.newtonking.com/projects/json /help/ReducingSerializedJSONSize.html
According to the JSON spec: "Whitespace can be inserted between any pair of tokens."
http://www.json.org/
So don't worry about it.
Or read about JSON formatting here http://james.newtonking.com/projects/json/help/ReducingSerializedJSONSize.html
您不应该手动 JSON 序列化该列表。
当您通过 POST 调用 ASP.NET 并使用
application/json
内容类型时,ASP.NET 已经自动为您完成此操作。因此,您最终会得到一个双重序列化的响应,这就是为什么您发现在 jQuery 已经解析它一次之后需要再次解析它。如果您使用 List 的返回类型并直接返回列表,那么您应该处于良好状态。

You should not manually JSON serialize that List.
ASP.NET is already doing it for you automatically when you call it via POST and use a content-type of
application/json
. So, you're ending up with a doubly serialized response, and that is why you've found that you need to parse it a second time after jQuery has already parsed it once.If you use a return type of List and return the list directly, you should be in good shape.
