[英]Unable to convert Json String to Json Object in c#
I have an Json string which is receiveCount({\\"url\\":\\"http://www.google.com\\",\\"count\\":75108})
我有一个Json字符串,它是
receiveCount({\\"url\\":\\"http://www.google.com\\",\\"count\\":75108})
My complete Method is 我完整的方法是
public void GetPinCount(string url)
{
string QUrl = "https://api.pinterest.com/v1/urls/count.json?callback=receiveCount&url=" + url;
System.Net.HttpWebRequest Request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(QUrl);
Request.ContentType = "text/json";
Request.Timeout = 10000;
Request.Method = "GET";
string content;
using (WebResponse myResponse = Request.GetResponse())
{
using (System.IO.StreamReader sr = new System.IO.StreamReader(myResponse.GetResponseStream(), System.Text.Encoding.UTF8))
{
content = sr.ReadToEnd();
}
};
var json = JObject.Parse(content);
var share_count = json["receiveCount"]["count"].ToString();
Console.WriteLine("Share Count :" + share_count);
}
When I am trying to access the count i am getting an exception like 当我尝试访问计数时,出现了类似的异常
Unexpected character encountered while parsing value: r. Path '', line 0, position 0.
Please tell me how this can be done. 请告诉我该怎么做。
Your string is not valid JSON : 您的字符串不是有效的JSON:
receiveCount(`{\"url\":\"http://www.google.com\",\"count\":75108}`)
The valid JSON part is the parameter : 有效的JSON部分是参数:
{"url":"http://www.google.com","count":75108}
You must extract the valid JSON part from your string to deserialize it. 您必须从字符串中提取有效的JSON部分以反序列化。
You are calling the wrong property. 您正在调用错误的属性。
You should use 你应该用
var share_count = json["count"].ToString();
instead of, 代替,
var share_count = json["receiveCount"]["count"].ToString();
Code to use with response: 用于响应的代码:
var json = JObject.Parse (content);
var share_url = json["url"];
Console.WriteLine ("Share URL:" + share_url);
var share_count = json["count"];
Console.WriteLine ("Share Count:" + share_count);
EDIT 1: 编辑1:
// Gets only the JSON string we need
content = content.Replace ("receiveCount(", "");
content = content.Remove (content.Length - 1);
// Converts JSON string to Object
var json = JObject.Parse (content);
var share_url = json["url"];
Console.WriteLine ("Share URL:" + share_url);
var share_count = json["count"];
Console.WriteLine ("Share Count:" + share_count);
