I have this reponse as JSON object.
Object {auth_token: "60a483bc0b1bc4dc0231ff0b90a67be1dad6ef45"}
auth_token:"60a483bc0b1bc4dc0231ff0b90a67be1dad6ef45"
proto
:
Object
I want to extract "60a483bc0b1bc4dc0231ff0b90a67be1dad6ef45" from this object. How can I do that?
If you've assigned that response to a variable:
var someObject = {auth_token: "60a483bc0b1bc4dc0231ff0b90a67be1dad6ef45"};
You can extract the value by using object.key notation
var valueForKey_auth_token = this.someObject.auth_token;
console.log("valueForKey_auth_token", valueForKey_auth_token);
And you'll see this on the console
valueForKey_auth_token 60a483bc0b1bc4dc0231ff0b90a67be1dad6ef45

How do i write an expression to obtain the value "lastUpdated" in the below json response data
{"resourceType":"Parameters","parameter":[{"name":"medication","resource":{"resourceType":"Bundle","id":"956ffe6a-08ed-4cb6-82ca-41065a4a9923","meta":{"lastUpdated":"2020-08-24T19:09:18.5649325+00:00",
I have tried this but it does not work:
regex("\"lastUpdated\": \"(.*?)\"").saveAs("lastUpdated")
this also does not work:
jsonPath("$..[?(#.use==\"lastUpdated\")].value").saveAs("lastUpdated"))
Your input is a little cut off but here is what I've got:
myJSONString = '{"resourceType":"Parameters","parameter":[{"name":"medication","resource":{"resourceType":"Bundle","id":"956ffe6a-08ed-4cb6-82ca-41065a4a9923","meta":{"lastUpdated":"2020-08-24T19:09:18.5649325+00:00"}}}]}'
myJSONObject = JSON.parse(myJSONString)
myLastUpdated = myJSONObject.parameter[0].resource.meta.lastUpdated
console.log(myLastUpdated)
Basically you convert it from a json object into a javascript object. Then you can just traverse down the tree to your intended target.
I am creating a JSON model in UI5 from a json object. But it is missing the columns array in the JSON model. I checked the model in the console and the odata property had no columns. Check image for proof.
https://ibb.co/hLmYpZb
Hence I want to know how I can get the column to show up.
Here is my code.
var emptyModel = {
"columns": []
};
this.setModel(new JSONModel(JSON.stringify(emptyModel)), "selcontent");
I expect column to show up in the JSON model under the odata property.
JSONModel awaits a plain object or a URL string as the first argument.
Either the URL where to load the JSON from or a JS object (source)
The result of the stringified emptyModel is "{"columns":[]}" which is neither an object nor a URL.
I am trying to use com.jayway.jsonpath.JsonPath to read key/values from a JSON string:
String contentAsString = mvcResult.getResponse().getContentAsString();
System.out.println(contentAsString);
Object value = JsonPath.read(contentAsString, "$.key");
But I get the error:
Expected to find an object with property ['key'] in path $ but found 'net.minidev.json.JSONArray'. This is not a json object according to the JsonProvider: 'com.jayway.jsonpath.spi.json.JsonSmartJsonProvider'.
Printing contentAsString gives:
[{"firstName":"N","key":"mykey"}]
Is contentAsString not valid JSON?
The blob that you posted is not a valid JSON Object, however, it IS a valid JSON Array.
To read this using JsonPath, try using this:
Object value = JsonPath.read(contentAsString, "$[0].key");
This will get the value of the key object, from the 0th element of the initial array.
Anybody has any idea how to parse below type of JSON object where same object named objects are present in master object. Below is an example
abc{
"abc":"123"
}
How to parse the child abc value?
You can use Json.NET it is vary easy to use. Json.NET handles JSON arrays natively, and will parse them into any type, string,int etc.
Are you currently using a JSON framework? Maybe check out Json.NET: http://www.newtonsoft.com/json.
Then you could do something like:
int onetwothree = jObject.SelectToken("abc.abc");
You can use http://www.newtonsoft.com/json to parse any json string on c#:
Your example :
var jsonString= "{\"abc\":{ \"abc\":\"123\" }}";
var jObj = JObject.Parse(jsonString);
var abcValue = jObj.SelectToken("abc.abc").Value<string>();
I'm trying to deserialize some JSON coming back from couchbase into a dynamic type.
The document is something like this so creating a POCO for this would be overkill:
{
UsersOnline: 1
}
I figured that something like this would do the trick, but it seems to deserialize into a dynamic object with the value just being the original JSON
var jsonObj = _client.GetJson<dynamic>(storageKey);
results in:
jsonObj { "online": 0 }
Is there anyway I can get the couchbase deserializer to generate the dynamic type for me?
Cheers
The default deserializer for the client uses .NET's binary serializer, so when you save or read a JSON string, it's just a string. GetJson will always just return a string. However, there are a couple of options:
You could convert JSON records to Dictionary instances:
var appJson = "{ \"UsersOnline\" : 1, \"NewestMember\" : \"zblock\" }";
var result = client.ExecuteStore(StoreMode.Set, "userCount", appJson);
var item = client.GetJson<Dictionary<string, object>>("userCount");
Console.WriteLine("There are {0} users online. The newest member is {1}.",
item["UsersOnline"], item["NewestMember"]);
Or you could use a dynamic ExpandoObject instance:
var appJson = "{ \"UsersOnline\" : 1, \"NewestMember\" : \"zblock\" }";
var result = client.ExecuteStore(StoreMode.Set, "userCount", appJson);
dynamic item = client.GetJson<ExpandoObject>("userCount");
Console.WriteLine("There are {0} users online. The newest member is {1}.",
item.UsersOnline, item.NewestMember);
In either case you're losing static type checking, which seems like it's OK for your purposes. In both cases you get access to the JSON properties without having to parse the JSON into a POCO though...
Edit: I wrote a couple of extension methods that may be useful and blogged about them at http://blog.couchbase.com/moving-no-schema-stack-c-and-dynamic-types
