I've been trying to read this JSON with PHP:
{
"total_found":"49",
"1":{
"title":"Maze Runner-The Scorch Trials 2015 HD-TS x264-Garmin",
"category":"video",
"seeds":2141,
"leechs":1176,
"torrent_size":1122230176,
"torrent_hash":"29d3e7062825a62abdd877ee96dc3fea41183836"
},
"2":{
"title":"Maze.Runner-The.Scorch.Trials.2015.720P.HD-TS.x264.AC3.HQ.Hive-CM8",
"category":"hdrip",
"seeds":395,
"leechs":1856,
"torrent_size":3999751475,
"torrent_hash":"e1e14a5ccf540a739907db2e1e0d810ecdb8bebc"
}
}
How can I get each title and torrent_size?
The easiest thing to do is to decode the JSON to an array. PHP has a built-in function for this:
$results = json_decode($json_data);
http://php.net/manual/en/function.json-decode.php
To clearly see the array structure, try dumping the variable $results using print_r();, i.e.:
print_r($results);
Then you simply need to access the data using the array.
It will be something like $results[1]['torrent_size'];.

I have the following JSON format
{
"name":"xyz",
"age-group":"bb"
}
How to get sort out this JSON
I use the following code
const array = [{ "name":"xyz", "age-group":"bb"} ]
array.map((element) => {
Console.log(element.age-group)
});
I got an error:
Can't find variable: group
1st thing is you can't map object.
and in your case you set json object in array and then you are maping it.
so it must be like:
array[0].name;
but in second property, it has hyphen which looks like "age-group" to access object property containing hyphen is:
array[0].obj["age-group"] //this is return `bb`
so in your code it will be:
array.map((element) => {
console.log(element.obj["age-group"])
});
to access object property with hyphen(-) you need to use notation with square brackets.
I am working on Angular 6 and i want to post an array of JSON objects using a service class.
The following is my function
getrerun(data,file){
this.post=[];
for(var i=0;i<data.length;i++)
{
this.rerun.storeno=data[i].storeNo;
this.rerun.filetype=data[i].loadtype;
this.rerun.outboundsystem[0]=file;
this.rerun.createdate=data[i].createdDate;
this.post[i]=this.rerun;
console.log("------>"+JSON.stringify(this.rerun)+"------->"+JSON.stringify(this.post));
}
this.newurl=this.devurl+"rerun";
return this.http.post<any>(this.newurl,this.post);
}
newurl is the url of the rest api that i want to hit and this.post is the array that i am sending
The value of data is following:
[{"lastDate":"2019-02-20 12:36:27","storeNo":"G015","country":"SG","serviceStatus":"FAIL","createdDate":"2019-01-04 11:53:56","loadtype":"F"},{"lastDate":"2019-02-20 10:54:00","storeNo":"G121","country":"SG","serviceStatus":"FAIL","createdDate":"2019-01-23 16:29:33","loadtype":"F"}]
and file is 'TP';
However the post array that I am getting is this:
[{"outboundsystem":["TP"],"storeno":"G121","filetype":"F","createdate":"2019-01-23 16:29:33"},{"outboundsystem":["TP"],"storeno":"G121","filetype":"F","createdate":"2019-01-23 16:29:33"}]
this basically means that both the entries in the array are the same i.e this.post[0].storeno is same as this.post[1].storeno. However, they should have two different values.
What do I do about this?
I'm new to angularjs. I have a json.
{
"first": {
"content": {
"admin.nv.example.com": {
"start": "2016-02-24 06:04:12.772141"
}
}
}
}
This is my JSON response i want to obtain value of property name (start) in this whole response but whenever i try to access this property value by first.content.admin.example.com.start
it shows error:Cannot read property 'nv' of undefined(angularjs)
You should use a different syntax to access the dotted property name. In fact it is better to avoid names like 'admin.nv.example.com' containing dots.
This should work:
first.content['admin.example.com'].start
use first.content['admin.nv.example.com']
You should use the ["admin.nv.example.com"] notation.
You should understand the proper way of writing JSON. But you should use like this:
test['first']['content']['admin.nv.example.com'];
JSON formats
I have JSON array of Objects that comes from user page
{[1].id=10, [0].name=banana, [1].measurementSystem=g, [1].name=bacon, [0].id=2, [0].cal=23, [1].cal=23, [0].measurementSystem=g}
How can I get all IDs from this object array into a integer Java array?
I tried this:
DynamicForm data = Form.form().bindFromRequest();
for (String s : data.data().values()){
System.out.println(s);
}
But it returns the array of all values.
So how can I get those ids only?
If the DynamicForm isn't working, I'd suggest trying to just parse the JSON as JSON. You can get a JsonNode object from the request using this code:
JsonNode json = request().body().asJson();
Using this you can then process the JSON to pull out whatever data you need.
Working with JSON in Play should be documented here.
i have a list of lat/long objects on my server.
eg.
public class LatitudeLongitude
{
public float Latitude;
public float Longitude;
}
simple.
now, can i return a collection of these, in json format .. BUT ... i do not want to list the key, just the values.
This means the normal result would be something like ...
{ { lat: 111, long : 222 }, { lat: 333, long : 444 } } ..
but i'm hoping for...
{ {111, 222}, {333, 444} ..... }
{ {obj1.Lat, obj1.Long}, {obj2.Lat, obj2.Long} ... etc. ... }
Is this possible? I mean, i can make that string on the server side easily. But is that a correct JSON output format?
Can someone please confirm, etc.
cheers :)
PS. I hardly know any Json, so please don't hesitate to correct my poor examples above.
Use JSON arrays:
[ [111, 222], [333, 444], ... ]
Ayman's proposal isn't quite correct JSON syntax. As an object {..} is always composed of fields having a name. So we again would have object with 2 fields of type 'array' that don't have a name -> not valid json for an object.
There is a very good description of how a json string can look like at www.json.org. Looking at this description you'll see an object is not allowed without a name String for a field so this {111,222} is not a valid object in json, but this is valid [111,222] array. This is not a valid object {[111,222]} but this is {array1 : [111,222]}.
I guess what you actually want is most likely an array of arrays like this not encapsulated as an object.
[[111,222],[333,444]].
This approach would give you the choice to add as much arrays of lat/long as you like to the enclosing array and at the same time you can process the inner arrays no matter what size the outer array is with an javascript loop.
Hope that helped.
cheers

If you need to access it using the keys in JSON, you'll need to specify it (or use a JS to convert arrays to objects on the client side). Otherwise, arrays should work:
var json = [ [123, 456], [234, 567] ];
var convertedJson = [];
for (i = 0; i < json.length; ++i) {
var thisObj = new Object();
thisObj.latitude = json[i][0];
thisObj.longitude = json[i][1];
convertedJson[i] = thisObj;
}
But is that a correct JSON output
format?
You can paste in JSON at jslint.com to validate your JSON
The ASP.NET MVC JSON serializer should convert a IList<LatitudeLongitude> to something like this:
[{"Latitude":111,"Longitude":222},{"Latitude":333,"Longitude":444} .. ]
I believe that under the ASP.NET MVC JSON serializer is just a hot-wired .NET core Javascript serializer.
I dont think it's possible from .NET using a serializer. Prob need to render the string manually.
