System.ArgumentException: Invalid JSON primitive error
提问by Ortal
I am getting "System.ArgumentException: Invalid JSON primitive: pagenum" when I return "sdata" in the following code:
当我在以下代码中返回“sdata”时，我收到“System.ArgumentException：无效的 JSON 原语：pagenum”：
function getPageData() {
pagenum = parseInt(eSc("#resultsBtn").attr("data-pagenum"));
if (pageName === "Home") {
scrollPath = "/Home/GetResults/";
sdata = { "pagenum": pagenum, "sortType": sortType };
}
else if (pageName === "Search") {
scrollPath = "/SearchAjax/GetResultsKeyword/";
sdata = { "pagenum": pagenum, "sortType": sortType, "keyword": keyword };
}
else if (pageName === "Cat") {
scrollPath = "/SearchAjax/GetResultsCategory/";
sdata = { "pagenum": pagenum, "sortType": sortType, "ID": categoryId, "Level": level };
}
else if (pageName === "Merchant") {
scrollPath = "/SearchAjax/GetResultsMerchant/";
sdata = { "pagenum": pagenum, "sortType": sortType, "ID": merchantId };
}
}
}
and the init function on pageload:
以及页面加载上的 init 函数：
function init(a, b, c, d, e, f, g) {
getPageData();
eSc.ajax({
type: 'POST',
url: scrollPath,
data: sdata,
success: function (data) {
eSc("#moreResults").html(data);
}
});
}
}
users dont see an issue and the correct data is still returned, yet I am getting an error email every time someone loads more data from our site in production (doesnt happen in development so its hard to troubleshoot). When inspecting in firebug, I see the correct data is passed. So why am I still getting this error?!
用户没有看到问题，仍然返回正确的数据，但每次有人从我们的生产站点加载更多数据时，我都会收到一封错误电子邮件（在开发中不会发生，因此很难排除故障）。在萤火虫中检查时，我看到传递了正确的数据。那么为什么我仍然收到此错误？！
Any tips as to why this might be happening?
关于为什么会发生这种情况的任何提示？

function init(a, b, c, d, e, f, g) {
getPageData();
eSc.ajax({
type: 'POST',
url: scrollPath,
contentType: 'application/json',
dataType: 'json',
data: JSON.stringify(sdata ),
success: function (data) {
eSc("#moreResults").html(data);
}
});
pass sData in json format, using JSON.stringify to format data in json format.
以json格式传递sData，使用JSON.stringify将数据格式化为json格式。
It works in my case. Hope it work in your case.
它适用于我的情况。希望它适用于您的情况。

var param = "{'type': '" + type + "'}";
var paramSfy = JSON.stringify({ type: type})
var src = '/Physical_Inventory/Home/runZeroQtyDLIUpdate';
$.ajax({
type: "POST",
url: src,
dataType: "json",
contentType: "application/json; charset=utf-8",
data: paramSfy,
What I noticed is,
我注意到的是，
if you are using contentType: "application/json; charset=utf-8" then the data is expected as a string:
如果您使用的是 contentType: "application/json; charset=utf-8" 那么数据应该是一个字符串：
"{ "Param" : "Value" }"
this is best accomplished by using the JSON.stringify function.
这最好通过使用 JSON.stringify 函数来完成。
if you don't set a content type then the default is, "application/x-www-form-urlencoded; charset=UTF-8" If you use this content type, then the param and value are embeded into the url, and the data can be set in ajax like so:
如果您不设置内容类型，则默认值为 "application/x-www-form-urlencoded; charset=UTF-8" 如果您使用此内容类型，则将参数和值嵌入到 url 中，并且数据可以像这样在ajax中设置：
data: {Param : Value},

jQuery serializes $.ajax()'s data parameter using the URL encoded scheme, regardless of what Content-Type is specified. I recommend to use the content type in ajax:
jQuery 使用 URL 编码方案序列化 $.ajax() 的数据参数，无论指定什么 Content-Type。我建议在 ajax 中使用内容类型：
function init(a, b, c, d, e, f, g) {
getPageData();
eSc.ajax({
type: 'POST',
url: scrollPath,
contentType: 'application/json',
dataType: 'json',
data: sdata,
success: function (data) {
eSc("#moreResults").html(data);
}
});
Also you need to use quotes in data parameter. In your version it's a JavaScript object literal instead of JSON string.
您还需要在数据参数中使用引号。在您的版本中，它是一个 JavaScript 对象文字而不是 JSON 字符串。
function getPageData() {
pagenum = parseInt(eSc("#resultsBtn").attr("data-pagenum"));
if (pageName === "Home") {
scrollPath = "/Home/GetResults/";
sdata = '{ "pagenum":'+ pagenum +' , "sortType":'+ sortType +' }';
}
else if (pageName === "Search") {
scrollPath = "/SearchAjax/GetResultsKeyword/";
sdata = '{ "pagenum": ' + pagenum + ', "sortType": '+ sortType +', "keyword": ' + keyword +' }';
}
else if (pageName === "Cat") {
scrollPath = "/SearchAjax/GetResultsCategory/";
sdata = '{ "pagenum":'+ pagenum + ', "sortType":'+ sortType +', "ID":'+ categoryId +', "Level": '+level+' }';
}
else if (pageName === "Merchant") {
scrollPath = "/SearchAjax/GetResultsMerchant/";
sdata = '{ "pagenum":'+ pagenum +', "sortType":'+ sortType + ', "ID":'+ merchantId +'}';
}
I hope it helps.
我希望它有帮助。
