Jquery AJAX Post: 500 (Internal Server Error)?
提问by user5535577
I am trying post a string to web service but I am getting this error (Google Chrome Extension Project):
我正在尝试将字符串发布到网络服务，但出现此错误（Google Chrome 扩展项目）：
jquery-2.1.1.min.js:4 POST http://localhost:49242/Service.asmx/test500 (Internal Server Error)
jquery-2.1.1.min.js:4 POST http://localhost:49242/Service.asmx/test500（内部服务器错误）
Here is my ajax code:
这是我的ajax代码：
var data = {};
data.param1 = words[0];
$.ajax({
data: JSON.stringify({ 'data': data.param1 }),
dataType: 'application/json',
url: 'http://localhost:49242/Service.asmx/test',
type: 'POST',
contentType: 'application/json; charset=utf-8',
success: function (result) {
alert(result);
},
failure: function (errMsg) {
alert(errMsg);
}
});
My service:
我的服务：
[WebMethod]
[System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
public string test(string param1) {
return param1;
}
I am working on this problem about 3 days. Can you help me ?
我正在解决这个问题大约 3 天。你能帮助我吗 ？
By the way, I have a question. I am posting json variable to service with ajax(like you see), but service returning xml value. Is there a problem or [System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]this code block solving problem?
顺便说一下，我有一个问题。我正在使用 ajax 将 json 变量发布到服务（如您所见），但服务返回 xml 值。是否有问题或[System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]此代码块解决问题？

Your error come from your data parameter. Stringify dataobject instead of { 'data': data.param1 }:
您的错误来自您的数据参数。字符串化data对象而不是{ 'data': data.param1 }：
var data = {};
data.param1 = words[0];
$.ajax({
data: JSON.stringify(data),
dataType: 'application/json',
url: 'http://localhost:49242/Service.asmx/test',
type: 'POST',
contentType: 'application/json; charset=utf-8',
success: function (result) {
alert(result);
},
failure: function (errMsg) {
alert(errMsg);
}
});
Your stringifyed data will result in {"param1":"Words"}, then your service should be able to bind the param1parameter.
您的字符串化数据将导致{"param1":"Words"}，那么您的服务应该能够绑定param1参数。

I was facing this type of error on AJAX post response. I was spending too much time behind this issue and finally I caught it.
我在 AJAX 发布响应中遇到了这种类型的错误。我在这个问题上花了太多时间，最后我抓住了它。
It throws a 500 internal error because the AJAX response has a lot of content from the server so it returns a timeout of execution.
它抛出一个 500 内部错误，因为 AJAX 响应有很多来自服务器的内容，因此它返回执行超时。
So I just added the line below and it's working fine.
所以我只是添加了下面的行并且它工作正常。
Page.Server.ScriptTimeout = 300;
