使用此服务我想在senchatouch2中使用POST方法将数组值存储到数据库中.Service写在(WCF)
服务声明:
[OperationContract]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "/Check1")]
int Psngr(string[] FirstName);
服务定义:
public static int Psngr(string[] FirstName)
{
List<Psgr> psgr = new List<Psgr>();
var getVal = from s in FirstName select s;
int count = getVal.Count();
SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["db"].ToString());
con.Open();
using (var cmd = new SqlCommand("SP_InsertCheck1", con))
{
int result;
cmd.CommandType = CommandType.StoredProcedure;
for (int i = 0; i < count; i++)
{
cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("@FirstName", FirstName[i]);
using (var Da = new SqlDataAdapter(cmd))
using (var Ds = new DataSet())
{
Da.Fill(Ds);
result = Convert.ToInt16(Ds.Tables[0].Rows[0]["Result"].ToString());
}
}
return 1;
}
}
我通过我的ajax请求访问此服务,如下所示:
Ext.Ajax.request({
url:'http://ws.easy4booking.com/E4b.svc/Check1',
method:'POST',
disableCaching: false,
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
params: {
FirstName:fname_toString, //FirstName:["Sam","Paul"],
},
success:function(response) {
console.log(response);
}
});
当我访问上面提到的这个服务时,我得到了以下错误
请求错误:
服务器在处理请求时遇到错误。异常消息是'格式化程序在尝试反序列化消息时引发异常:反序列化操作'Psngr'的请求消息正文时出错。遇到意想不到的字符'F'。'。请参阅服务器日志以获取更多详异常堆栈跟踪是:

当v使用POST方法在SenchaTouch2中传递参数时,在Ajax请求中使用 jsonData ,
Ext.Ajax.request({ 网址: '', 方法: 'POST', disableCaching:假的, 标题:{ '接受': '应用/ JSON', “内容类型”:“应用/ JSON” }, jsonData :{ FirstName:fname // {“FirstName”:[“Sam”,“paul”]} }, 成功:功能(响应) { 的console.log(response.responseText); }, 失败:功能(响应) { 的console.log(response.responseText); }, });

当您的客户端向WCF Rest服务发出请求时,原始请求应如下所示:
POST http://localhost/SampleService/RestService/Check1 HTTP/1.1
User-Agent: Fiddler
Content-Type: application/json
Host: localhost
Content-Length: 33
{"FirstName":["Sam","paul"]}
好像你的sencha代码正在传递WCF无法反序列化的字符串[]。您可以考虑将其作为jsonData而不是param传递。
另请查看这可能有用的link。(他们尝试使用的服务是在Spring MVC中,但我想它对于WCF服务也应该是相同的)
