I want to get tmX, tmY from this json, but I can not get it.
How can I get a value?
I do not think there's anything more to write ...
{
"list":[
{
"_returnType":"json",
"map":"",
"numOfRows":"10",
"pageNo":"1",
"tmX":"196543.111337",
"tmY":"173653.845412"
}
],
"totalCount":1
}
QString tmX, tmY;
if (jsonObj.contains("list")) {
QJsonObject listObj = jsonObj["list"].toObject();
if (listObj.contains("tmX"))
tmX = listObj["tmX"].toString();
if (listObj.contains("tmY"))
tmY = listObj["tmY"].toString();
}

in this json file I want to get original_ur but when i cant get it , can some one help me how to get it please
{
"orders": {
"order_items":[
{
"product_min":{
"colors":[
{
"media":[
{
"original_url": b
"https://royalpetiq.com/royalpet2/public//storage/10628/msg5212971698-890.jpg",
}
]
}
]
}
}
]
}
}
go on quicktype id site and create model from this json after just creat object of that claass and parse this json response and after that you can get valu like
x.orders.order_items[0].product_min.colors[0].media[0].original_url
here is your json path
x.orders.order_items[0].product_min.colors[0].media[0].original_url
try {
var json = """{
"orders": {
"order_items":[
{
"product_min":{
"colors":[
{
"media":[
{
"original_url": "https://royalpetiq.com/royalpet2/public//storage/10628/msg5212971698-890.jpg"
}
]
}
]
}
}
]
}
}""";
var data = jsonDecode(json);
var url = data["orders"]["order_items"][0]["product_min"]["colors"][0]
["media"][0]["original_url"];
print("Url: $url");
} catch (e) {
print(e);
}
I think your json should be like that.
Here the url has a b at the beginning and a comma after the url which is not the correct syntax for json
Hope anybody could guide me here. I spend some hours on it and can't understand what's going on.
Mission: Replace a json element by a jsonpath search tag. (sort of $ref feature)
In my code example below i want to replace the value of DataReaderUser by a value found by the json path search $.UsersAndGroups.Users[?(#.Name == 'OMDASAccountUser')].Username . In this case it should result in the value "contoso\SVCSCOM-DO-OMDAS"
The code below works as expected.. the issue is below this code ..
https://dotnetfiddle.net/gEjggK
using System;
using Newtonsoft.Json.Linq;
public class Program
{
public static void Main()
{
string json = #"{
""SQLServer"": {
""SQLReportingServices"": {
""AccountSettings"": {
""DataReaderUser"": {""$JsonPath"": ""$.UsersAndGroups.Users[?(#.Name == 'OMDASAccountUser')].Username""},
}
}
},
""UsersAndGroups"": {
""Users"": [
{
""Name"": ""OMActionAccountUser"",
""Username"": ""contoso\\SVCSCOM-DO-OMDAS"",
},
{
""Name"": ""OMDASAccountUser"",
""Username"": ""contoso\\SVCSCOM-DO-OMDAS"",
}
]
}
}";
JObject jo = JObject.Parse(json);
var JsonPath = jo.SelectToken("..$JsonPath");
JsonPath.Parent.Parent.Replace(jo.SelectToken(JsonPath.ToString()));
Console.WriteLine(jo.ToString());
}
}
The output will be :
{
"SQLServer": {
"SQLReportingServices": {
"AccountSettings": {
"DataReaderUser": "contoso\\SVCSCOM-DO-OMDAS"
}
}
},
"UsersAndGroups": {
"Users": [
{
"Name": "OMActionAccountUser",
"Username": "contoso\\SVCSCOM-DO-OMDAS"
},
{
"Name": "OMDASAccountUser",
"Username": "contoso\\SVCSCOM-DO-OMDAS"
}
]
}
}
Now the issue:
I want to do the same for all possible jsonpaths refers. So i use the SelectTokens and an foreach . But it looks like the behavior is different , the parents are null.
https://dotnetfiddle.net/lZW3XP
using System;
using Newtonsoft.Json.Linq;
public class Program
{
public static void Main()
{
string json = #"{
""SQLServer"": {
""SQLReportingServices"": {
""AccountSettings"": {
""DataReaderUser"": {""$JsonPath"": ""$.UsersAndGroups.Users[?(#.Name == 'OMDASAccountUser')].Username""},
}
}
},
""UsersAndGroups"": {
""Users"": [
{
""Name"": ""OMActionAccountUser"",
""Username"": ""contoso\\SVCSCOM-DO-OMDAS"",
},
{
""Name"": ""OMDASAccountUser"",
""Username"": ""contoso\\SVCSCOM-DO-OMDAS"",
}
]
}
}";
JObject jo = JObject.Parse(json);
var JsonPaths = jo.SelectTokens("..$JsonPath");
foreach (var JsonPath in JsonPaths )
{
JsonPath.Parent.Parent.Replace(jo.SelectToken(JsonPath.ToString()));
}
Console.WriteLine(jo.ToString());
}
}
And the output:
Run-time exception (line 34): Object reference not set to an instance of an object.
Stack Trace:
[System.NullReferenceException: Object reference not set to an instance of an object.]
at Newtonsoft.Json.Linq.JsonPath.PathFilter.GetNextScanValue(JToken originalParent, JToken container, JToken value)
at Newtonsoft.Json.Linq.JsonPath.ScanFilter.<ExecuteFilter>d__4.MoveNext()
at Program.Main() :line 34
would be great to get some directions since i am spinning my head here.

SelectTokens uses lazy evaluation and if you modify the token while enumerating all matches it can break in unexpected ways. A simple fix is to add ToArray() to force eager evaluation:
var JsonPaths = jo.SelectTokens("..$JsonPath").ToArray();
I need to take out 1000 from this Key-Value Pair in node Js
"msg":"amamm : ErrorResponse {\"abcd1\":{\"Status\":\"E\",\"rem\":{\"Code\":\"1000\",\"message\":\"Unable to access your information at this time.(1000)\"}}}"
The JSON what you have posted is invalid. May be your JSON should be like the following:
var json = {
"msg": {
"amm": {
"ErrorResponse": {
"abcd1": {
"Status": "E",
"rem": {
"Code": "1000",
"message": "Unabletoaccessyourinformationatthistime.(1000)"
}
}
}
}
}
}
Then in node.js you have get the value using dot notation like as follows:
json.msg.amm.ErrorResponse.abcd1.rem.code
Will give you the value 1000
Assuming you can get the string
amamm : ErrorResponse {\"abcd1\":{\"Status\":\"E\",\"rem\":{\"Code\":\"1000\",\"message\":\"Unable to access your information at this time.(1000)\"}}}
by doing err.msg
You can get the json and then get the string you want. I copied the content of the msg into a variable str just to test the regex
var re = /\{.*?\}$/;
var str = 'amamm : ErrorResponse {\"abcd1\":{\"Status\":\"E\",\"rem\":{\"Code\":\"1000\",\"message\":\"Unable to access your information at this time.(1000)\"}}}';
var m;
if ((m = re.exec(str)) !== null) {
if (m.index === re.lastIndex) {
re.lastIndex++;
}
var content = JSON.parse(m[0]);
console.log(content);
console.log(content.abcd1.rem.Code);
}
Here's a working example: http://jsfiddle.net/sger1gk6/
I have this json:
{
"Message": "The request is invalid.",
"ModelState": {
"Email": [
"The Email field is required."
]
}
}
I want to find the ModelState(if it exists) and then loop through all the errors that re in there.
I can figure out how to do this. I don't want to make a concrete class as the data might change depending on what happens on the sever.
I also can use dynamic as I am on WPF7
JObject jsonObj = JObject.Parse(response.Content);
foreach (var j in jsonObj)
{
var t = j.Value;
}
this is what I have so far.
JObject jsonObj = JObject.Parse(response.Content);
var modelState = jsonObj["ModelState"];
if (modelState != null)
{
// The JSON contains a property called ModelState
// so we can start looping through it:
foreach (JProperty item in modelState)
{
Console.WriteLine(item.Name);
foreach (JValue error in item.Values())
{
Console.WriteLine(error);
}
}
}
I'm working on something that involved using the Bit.ly API, and allow the user to select theformat (Text, XML, Json) the text & XML are completed. This is the Json result that is returned when you shorten a URL:
{
"status_code": 200,
"status_txt": "OK",
"data":
{
"long_url": "http:\/\/panel.aspnix.com\/Default.aspx?pid={Removed}",
"url": "http:\/\/rlm.cc\/gtYUEd",
"hash": "gtYUEd",
"global_hash": "evz3Za",
"new_hash": 0
}
}
And this C# code works just fine to parse it and get the short URL:
var serializer2 = new JavaScriptSerializer();
var values2 = serializer2.Deserialize<IDictionary<string, object>>(json);
var results2 = values2["data"] as IDictionary<string, object>;
var shortUrl2 = results2["url"];
expandedUrl = results2["url"].ToString();
return results2["url"].ToString();
Now here's the Json sent back when expanding a URL:
{
"status_code": 200,
"status_txt": "OK",
"data":
{
"expand":
[
{
"short_url": "http:\/\/rlm.cc\/gtYUEd",
"long_url": "http:\/\/panel.aspnix.com\/Default.aspx?pid={Removed}",
"user_hash": "gtYUEd",
"global_hash": "evz3Za"
}
]
}
}
Ad that's where my problem begins, how can I change my current C# to be able to handle both scenarios, because as you can see their vastly different from each other. Any ideas?
I usually use Json.NET to cherrypick values out of JSON documents. The syntax is very concise. If you reference NewtonSoft.Json.dll and use Newtonsoft.Json.Linq, you can write the following:
var job = JObject.Parse(jsonString);
if (job["data"]["expand"] == null)
{
Console.WriteLine((string)job["data"]["url"]);
}
else
{
Console.WriteLine((string)job["data"]["expand"][0]["long_url"]);
}
If jsonString is:
string jsonString = #"{""status_code"": 200, ""status_txt"": ""OK"", ""data"": {""long_url"": ""http:\/\/panel.aspnix.com\/Default.aspx?pid={Removed}"", ""url"": ""http:\/\/rlm.cc\/gtYUEd"", ""hash"": ""gtYUEd"", ""global_hash"": ""evz3Za"", ""new_hash"": 0 }}";
the routine will display http://rlm.cc/gtYUEd.
If jsonString is:
string jsonString = #"{""status_code"": 200, ""status_txt"": ""OK"", ""data"": { ""expand"": [ { ""short_url"": ""http:\/\/rlm.cc\/gtYUEd"", ""long_url"": ""http:\/\/panel.aspnix.com\/Default.aspx?pid={Removed}"", ""user_hash"": ""gtYUEd"", ""global_hash"": ""evz3Za"" } ] } }";
the routine will display http://panel.aspnix.com/Default.aspx?pid={Removed}.
Not sure I got your problem. Why aren't you testing, if you got a shortening result or a expanding result? Since they are different, this could easily be done via simple 'if ()' statements:
if (results2.ContainsKey("expand")) {
// handle the expand part
} else {
// handle the shorten part
}
Assuming that the provider is consistent with which form it sends, do you need to have code that handles both? It should be direct to handle each individually.
If you can't know ahead of time which format you will get back, you can do the following:
if (results2.ContainsKey("expand"))
{
//Second example
}
else
{
//First example
}
