不能使用jQuery的ASP.NET Web服务 [英] Can't consume ASP.NET Web Service from jQuery
问题描述
这是一个有趣的问题:
我有一些看起来像这样的jQuery:
I have some jQuery that looks like this:
$(document).ready(function() {
$.ajax({
type: "POST",
url: "http://localhost:63056/Service1.asmx/PrintOrderRecieptXml",
data: {
"CouponCode": "TESTCODE",
"Subtotal": 14.2600,
"ShippingTotal": 7.5000,
"TaxTotal": 0.0000,
"GrandTotal": 21.7600,
"OrderItemCollection": [{
"Total": 14.2600,
"Qty": 250
}]
},
dataType: "json",
contentType: "application/json",
error: function(xhr, msg) {
alert(xhr.statusText);
}
});
});
现在,我遇到的问题是它正在发送请求,但是Web服务未正确处理它.在IE中,我收到一个带有内部服务器错误"的警报框,而在FireFox中,我得到一个没有任何内容的警报框.
Now, the problem I'm having is that it's sending the request, but the web service isn't processing it correctly. In IE, I get an alert box with "Internal Server Error" and with FireFox I get an alert box with nothing in it.
奇怪的是,当我使用IE时,我的事件日志中没有出现错误事件,但是使用firefox时,我得到了(要弄清楚为什么是这样的奖励积分):
The strange thing is that when I use IE, I do not get an error event in my event log, but with firefox I get (bonus points for figuring out why this is):
异常消息:无法识别以'/PrintOrderRecieptXml结尾的URL的请求格式"
"Exception message: Request format is unrecognized for URL unexpectedly ending in '/PrintOrderRecieptXml"
我戳了一下,发现有时候你必须添加:
I poked around some and found out that sometimes you have to add:
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost" />
<add name="HttpPostLocalhost"/>
</protocols>
</webServices>
到您的Web.Config,我这样做了,但没有帮助.有趣的是,Web服务可以与SOAP或发送查询字符串一起正常工作,但不能与JSON一起工作.
To your Web.Config, which I did but it did not help. The interesting thing is that the web service works fine with SOAP or sending a query string, but not with JSON.
有什么想法吗?
推荐答案
您需要将输入的 data
属性作为JSON字符串而不是对象:
You need to give your input to the data
property as a JSON string, not as an object:
$(document).ready(function() {
$.ajax({
type: "POST",
url: "http://localhost:63056/Service1.asmx/PrintOrderRecieptXml",
data: '{"CouponCode":"TESTCODE","Subtotal":14.2600,"ShippingTotal":7.5000,"TaxTotal":0.0000,"GrandTotal":21.7600,"OrderItemCollection":[{"Total":14.2600,"Qty":250}]}',
dataType: "json",
contentType: "application/json",
error: function(xhr, msg) {
alert(xhr.statusText);
}
});
});
使用jQuery进行消费当与ASP.Net Web服务进行通信时,ASP.NET JSON Web服务很好地解释了这些要求.
Using jQuery to Consume ASP.NET JSON Web Services has a good explanation of the requirements when talking to ASP.Net Web Services.
