contentType:"application/json; charset=utf-8", 作用是把数据整个按照json格式发送，接收的方法

Response.ClearContent();

按照你的方法获取的 数据
但是 后台怎么获取呢
我只一直没有获取到

[孟子E章]

也可以这样写
<script type="text/javascript">
$(document).ready(function () {
$.ajax({
type: "post",
url: "demo.aspx?" + (new Date()).valueOf(),
data: '{"param1":"8888","param2":"参数2"}',
contentType: "application/json; charset=utf-8",
dataType: "text",
success: function (result) {
alert(result);
}
});
});
</script>

注意data的格式差异

方法1
data: '{ "id":"C","name":"","sex":"男","department":"","companyPlace":"","in_job_date":"","job":"","jobPort":"","AdminRate":"","SubsidyRate":"","phone":"","benchId":"0","person_id":"","birthday":"","marriage":"未婚","census":"0","reg_place":"","reg_address":"","live_place":"","live_address":"","linkman":"","emergent_phone":"","zip_code":"","nationality":"汉族","politics":"群众","education":"","bank_account":"","bank_Name":"","bank_city":"","passport_id":"","contract_timeLimit":"","probation":"","contract_date_op":"","contract_date_ed":"","ceshi":"","ceshi2":"数据测试"}',

注意单引号，

后台接收
String s = (new System.IO.StreamReader(Request.InputStream)).ReadToEnd();

[孟子E章]

方法2
data: { "id":"C","name":"","sex":"男","department":"","companyPlace":"","in_job_date":"","job":"","jobPort":"","AdminRate":"","SubsidyRate":"","phone":"","benchId":"0","person_id":"","birthday":"","marriage":"未婚","census":"0","reg_place":"","reg_address":"","live_place":"","live_address":"","linkman":"","emergent_phone":"","zip_code":"","nationality":"汉族","politics":"群众","education":"","bank_account":"","bank_Name":"","bank_city":"","passport_id":"","contract_timeLimit":"","probation":"","contract_date_op":"","contract_date_ed":"","ceshi":"","ceshi2":"数据测试"},

接收
String s = Server.UrlDecode( (new System.IO.StreamReader(Request.InputStream)).ReadToEnd());

[孟子E章]

方法3
$(document).ready(function () {
$.ajax({
type: "post",
url: "demo.aspx?" + (new Date()).valueOf(),
data: { "id":"C","name":"","sex":"男","department":"","companyPlace":"","in_job_date":"","job":"","jobPort":"","AdminRate":"","SubsidyRate":"","phone":"","benchId":"0","person_id":"","birthday":"","marriage":"未婚","census":"0","reg_place":"","reg_address":"","live_place":"","live_address":"","linkman":"","emergent_phone":"","zip_code":"","nationality":"汉族","politics":"群众","education":"","bank_account":"","bank_Name":"","bank_city":"","passport_id":"","contract_timeLimit":"","probation":"","contract_date_op":"","contract_date_ed":"","ceshi":"","ceshi2":"数据测试"},
success: function (result) {
alert(result);
}
});
});

接收
Response.ClearContent();
for (int i = 0; i < Request.Form.Count;i++ )
Response.Write(Request.Form.Keys[i] + "=" + Request.Form[Request.Form.Keys[i]] + "\r\n");
Response.End();

这个返回的是个 XMLDocument()

[孟子E章]

dataType: "text",

Response.ContentType="text/plain"

[一米曙光]

仔细再检查一下代码呢

[aling_freedom]

demo.aspx?这个问号是在这里加的吗，我们java的是定义一个变量
data : {"id" : op.id},这个“id”就是后台要接收的参数

[Wicho开源开发中]

问题 解决 虽然很复杂 ，感谢 net_lover ，感谢大家！

[guolinyong]

请问下 你那个是什么原因造成的

[Ray_Yang]

最讨厌他妈的解决了问题不说答案的2B

[牛牛04089]

data : {"id" : op.id},这个“id”就是后台要接收的参数 不知道这个id怎么在后台获取呢？

[SiriusGuo]

曰了，解决了说下方案啊！

[何小强]

dataType: "text" data: "data=hello", 后台直接context.Request["data"]

[xcchcaptain]

版主正解
http://api.jquery.com/jQuery.ajax/ 对于contentType的描述

[支持中文找回密码]

引用 37 楼 helun2008 的回复:

dataType: "text" data: "data=hello", 后台直接context.Request["data"]

data: "data=hello",这种形式的data是正解

[支持中文找回密码]

并且contentType选项要去掉，即： $.ajax({ type: "post", cache: false, url: url, data: "data=hello&type=xxx", dataType: "json", //contentType: "application/json; charset=utf-8", processData: false, success: function(data) { code = data.code,msg = data.msg; return false; }, error: function() { alert('错误'); return false; } });

我也遇到这个问题，用“get”的方式传到后台就可以，但是用“post”传到后台就找不到数据，看了大家的评论后把contentType: "application/json; charset=utf-8"去掉就可以，不知道是为什么，求解释。
