解析值时遇到意外字符:j.路径''，第0行，位置0 [英] Unexpected character encountered while parsing value: j. Path '', line 0, position 0

问题描述

t无法反序列化/处理此json，我尝试使用不同的方法进行多种组合以尝试使此工作有效，但似乎无济于事...

t fails to deserialize/prase this json, ive tried multiple combinations with different methods to try and make this work but nothing seems to do it...

我正在使用的代码

WebClient wc = new WebClient();


var json = (JObject)JsonConvert.DeserializeObject(wc.DownloadString("http://services.runescape.com/m=website-data/playerDetails.ws?names=[%22" + Username.Replace(" ", "%20") + "%22]&callback=jQuery000000000000000_0000000000&_=0"));

json试图反序列化...

the json its trying to deserialize...

jQuery000000000000000_0000000000([{"isSuffix":true,"recruiting":false,"name":"Sudo Bash","clan":"Linux Overlord","title":"the Troublesome"}]);

推荐答案

在Json规范中，您可以看到[表示json对象的开始数组，而{表示新json对象的开始.

In Json specification you can see that [ indicates the begining array of json objects while { indicates beginning of new json object.

您的json字符串以[开头，因此它可以包含更多json对象(因为它是一个数组，并且包含jQuery000000000000000_0000000000(这是您的查询字符串参数.要摆脱查询字符串垃圾，您应该找出方案如果您的json字符串以[开头，则建议您使用JsonConvert.DeserializeObject<T>()方法将json字符串反序列化为List<JObject>(如果以{开头，请使用标准类型)；

Your json string starts with [ so it can contains more json objects ( because it's an array and it contains jQuery000000000000000_0000000000( which is your query string parameter. To get rid of the query string garbage you should find out the scheme of that garbage and then to process json object I would recommend you to deserialize your json string into List<JObject> using JsonConvert.DeserializeObject<T>() method if your json string starts with [ ( use standard type if it is starting with { );

示例:

string url = // url from @Darin Dimitrov answer
string response = wc.DownloadString(url);
// getting rid of the garbage 
response = response.Substring(response.IndexOf('(') + 1);
response = response.Substring(0, response.Length - 1);
// should get rid of "jQuery000000000000000_0000000000(" and last occurence of ")"
JObject result = null;
if(response.StartsWith('['))
{
    result = JsonConvert.DeserializeObject<List<JObject>>(response)[0];
}
else 
{
    result = JsonConvert.DeserializeObject<JObject>(response);
}
