I want to index JsonObjects with NEST, after posting the properties are in the index but the values are empty "[]". When I post the same json with Postman the result is correct.
Index:
string indexName = "testindex";
IIndexResponse response = client.Index<JObject>(docItem, i => i.Type("my_type").Index(indexName));
json in docItem:
{
"Source":"test",
"CreatedAt": "2018-05-26 12:23:33",
"SessionId":"1234",
"ResponseParam":{
"ItemA":"bla",
"ItemB": 123
}
}
search query:
http://[IP]:9200/testindex/_search
search result
{
"took": 8,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 4,
"max_score": 1,
"hits": [
{
"_index": "testindex",
"_type": "my_type",
"_id": "u44ucmMB687Uyj7O8xKY",
"_score": 1,
"_source": {
"Source": [],
"CreatedAt": [],
"SessionId": [],
"ResponseParam": {
"ItemA": [],
"ItemB": []
}
}
},
If you're using JObject as the document type, or your document contains JObject, you will need to also reference the NEST.JsonNetSerializer nuget package and hook up the JsonNetSerializer as follows
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var connectionSettings =
new ConnectionSettings(pool, sourceSerializer: JsonNetSerializer.Default);
var client = new ElasticClient(connectionSettings);
This is required because NEST 6.x removed the direct dependency on Json.NET by IL-merging, internalizing and re-namespacing it. One of the changes this brings about is that now, NEST does not know how to specially handle Newtonsoft.Json.Linq.JObject, so the dependency on NEST.JsonNetSerializer which does know how to handle that type specially, is needed.

I am trying to integrate Shippo to our application and wish to obtain a specific value out of a Json response.

I am using this call:
WebClient webClient = new WebClient();
webClient.Headers.Add("Authorization: ShippoToken " + authToken);
var result = JsonValue.Parse(webClient.DownloadString("https://api.goshippo.com/shipments/"+ theObject.ObjectId + "/rates/USD"));
My question is how could I get just the "amount" value from the response?
Thank you for any help!
Instead of recreating the json layout as a class model you can work with Newtonsofts JToken. Which will leave you with less boilerplate code to create:
var json = "your json data";
// Parse the whole json string
var obj = JObject.Parse(json);
// Extract the results data as JArray
var results = (JArray)obj["results"];
// Iterate over all array entries and get the amount property
foreach(var result in results)
{
var amount = result["amount"].ToString();
// Do something with the amount
}
You could create some classes based on json then deserialize using JsonConvert
e.g https://www.newtonsoft.com/json/help/html/DeserializeObject.htm
tip:
Copy the json and put in json viewer like https://jsonformatter.curiousconcept.com/
Use https://www.newtonsoft.com/json to deserialize the json response. If you didn't want that you could use a series of string.Split()'s to get the amount. But using newtonsoft (via the nuget package manager) would be the easiest.
I am trying to retrieve an array containing a BSON document using C#. Below is the document structure and the code that I'm using in order to do that.
"_id": 199,
"name": "Rae Kohout",
"scores": [{
"type": "exam",
"score": 82.11742562118049
},
{
"type": "quiz",
"score": 49.61295450928224
},
{
"type": "homework",
"score": 28.86823689842918
},
{
"type": "homework",
"score": 5.861613903793295
}]
}
var db = client.GetDatabase("school");
var studentCol = db.GetCollection<BsonDocument>("students");
var builderDoc = Builders<BsonDocument>.Filter;
var filter=builderDoc.ElemMatch("scores", builderDoc.Eq("type","homework" ));
var result = studentCol.Find(filter);
When I execute this statement, the value of the result is coming as {find({ "scores" : { "$elemMatch" : { "type" : "homework" } } })}. If I apply .tolist(), I am seeing the data coming properly, but as a generic collection, where I'm not able to do any mongo querying on it.
How can I retrieve the document as an array?

You will have to create a class named as cases and then you need to map your json to the List then you can iterate through the list hope it will work for you .
List<cases> = new JavaScriptSerializer().Deserialize<List<cases>>(your json string);
You can install Json.Net package from Nuget and then add this line of code in you project
var myList = Newtonsoft.Json.JsonConvert.DeserializeObject("Your Json String..!!");
this should do it

I am trying to parse this using JSON.Net and i have tried this code.
var obj = JObject.Parse(json);
var query =
from JProperty ev in obj.AsJEnumerable()
from JProperty evid in ev.Value.AsJEnumerable()
let value = (JObject)evid.Value
select new
{
Description = (string)value["Description"]
};
I am getting this error "Unable to cast object of type 'Newtonsoft.Json.Linq.JValue' to type 'Newtonsoft.Json.Linq.JObject'."
i also want to read event_id which is inside results and dividents. Can anyone tell me what i am doing wrong here
Currently, you're getting the properties of the properties - and then trying to cast each of the values to JObject, and then taking the Description of that. That's one level too deep, as you have:
The root object
Each property of the root object, which genuinely has an object as its value
Each property of each of those values... most of which are just string properties, so the value can't be cast to JObject
It's not clear why you're using AsJEnumerable() at all, but all you need is the properties of the root object, which is easily obtained with the Properties() method. Likewise it's not clear why you're using an anonymous type, rather than just getting a sequence of strings. This works fine:
var query =
from ev in obj.Properties()
select (string) ev.Value["Description"];
Or without the query syntax:
var query = obj.Properties.Select(ev => (string) ev.Value["Description"]);
Next:
i also want to read event_id which is inside results and dividents
In the data you've given, that's always the same as the value of the EventID property in the top-level type. So you'd be better off with:
var query =
from ev in obj.Properties()
select new { Description = (string) ev.Value["Description"],
Id = (string) ev.Value["EventID"] };
If you really want to get at the values in the dividends and results, you'll need to work out how you'll handle the multiple entries in those properties.
I am using the NEST API (v0.12.0.0) to interface with an ElasticSearch (v1.0.1) index and I just started receiving a JsonSerializationException when retrieving my data. I'm not sure if this is a NEST issue or otherwise, but it just randomly started happening and we haven't made any major changes to our implementation or infrastructure.
I am attempting to retrieve the Ids of my data (stored as a Guid) with a typed Search<>() and I am getting an exception when the data is processed by JSON.NET.
client.Search<ESEventItem>(s =>
s.Index("dev-events004")
.Fields(f => f.Id).Size(100000)
.Type("event").MatchAll()).Documents.ToList()
Running this same query manually in Sense produces no noticeable issues:
POST /dev-events004/event/_search
{
"size": 100000,
"query": {
"match_all": {}
},
"fields": [
"id"
]
}
{
"took": 2088,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 19257,
"max_score": 1,
"hits": [
{

"_score": 1,
"fields": {

"670a1055-cbe3-480e-b807-a2b500f9dfb3"
]
}
},
/* ... additional results ... */
]
}
}
If I perform a raw, untyped query Fields(new[] { "Id" }) it does not throw an exception. Likewise, if I return the whole ESEventItem object, rather than just the Id fields, it also works without an exception.
To the NEST developer: this question is mirrored as an issue on the github project.
This is due the fact that elasticsearch 1.0 changed how fields are returned. The upcomming NEST 1.0 will support this.
