如何通过AJAX调用Web服务来返回Json数据？

Question

我有一个Web服务，它返回JSON数据，下面我用来调用Web服务的代码。

jQuery.ajax({ 
 
    url: 'http://localhost:5606/xyz', 
 
    type: "POST", 
 
    contentType: "application/json; charset=utf-8", 
 
    dataType: 'json', 
 
    data: '{"a":"b"}', 
 
    success: function(responses, textStatus, XMLHttpRequest) { 
 
    alert(responses); 
 
    }, 
 
    error: function(xhr, err) { 
 
    console.log("readyState: " + xhr.readyState + "\nstatus: " + xhr.status); 
 
    console.log("responseText: " + xhr.responseText); 
 
    }, 
 
    complete: function() {} 
 
}); 
 
};

其返回警报输出成功的功能像[目标对象]但我想它在正确的JSON格式。

您必须阅读JSON.stringify()

使用alert(JSON.stringify(data))

例子：

var response = {}; 

response.status ="success"; 
response.data="Your data"; 

alert(response); //It will give you [object object] 
console.log(response); //Gives JSON data in console 
alert(JSON.stringify(response)); //Alerts json string 

if(response.status == "success") 
    //Pass response.data to the next webservice it will still be in the json format.
