使用senchatouch2中的POST方法将数组作为参数发送

问题描述

使用此服务，我想使用senchatouch2中的POST方法将数组值存储到数据库中..服务写入(WCF)

Using this service i want to store array value into database using POST method in senchatouch2..Service is written in (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ajax请求访问了此服务，如下所示:

I accesssed this service through my ajax request as follows:

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);
    }
});

当我访问上述服务lik时，出现以下错误

When I accessed this service lik mentioned above i got following error

推荐答案

当v使用POST方法在SenchaTouch2中传递参数时，请在Ajax Request之类的 jsonData 中使用

When v use POST method to pass parameters in SenchaTouch2 use jsonData in Ajax Request like,
