如何与Web服务连接

Question

我正在尝试从Web服务获取一些数据：

$.ajax({
    type: 'POST',
    url: "http://192.******.asmx?op=GetJSONString",
    method: "serverCallback",
    data: "Select con.cod as codigo, con.res as descripcion from con where ide>0",
    success: function(data){alert(data)},    
});

如何获取返回的JSON数据？

Answer 1

这是我的电话的样子。你能更具体地说明你遇到的问题吗？

$.ajax({
    type: "POST", 
    data: "SOME DATA",      
    dataType: "json",
    url : "/myapp/service.json",
    cache: false,
    error: function() {     
                         alert("There was an issue");
        }
    ,
    success: function(data) 
    {                   
            processJson(data); 
    }
});

我还将发布与asmx服务有关的内容。

在下面的示例中，对于“url”：“/ service /Details.asmx / Reject”，“/ Reject”是Web服务（asmx）文件中的方法名称。

  $.ajax({
            "dataType": 'json',
            "contentType": "application/json; charset=utf-8",
            "type": "POST",
            "url": "/service/Details.asmx/Reject",
            "data": "{\"itemId\":\"" + id + "\",\"comment\":\"" + comms + "\"}",
            "success":
                        function (msg) {
                          alert("Yea it worked!");
                            });
                        }
        });
