may help you . If you have an express server, you can use the body-parser to get the data from the request body.
For example:
var bodyParser = require('body-parser');

app.route.post('/send', function(req, res){

  console.log( req.body.LoginTime );

wish of those help you can use it like this, in JSON format when you evaluate false value it will give you blank, and when you evaluate true it will give you 1.
$str = '[{"clientId":"17295c59-4373-655a-1141-994aec1779dc","channel":"\/meta\/connect","connectionType":"long-polling","ext":{"fm.ack":false,"fm.sessionId":"22b0bdcf-4a35-62fc-3764-db4caeece44b"},"id":"5"}]';

$arr = json_decode($str,true);

if($arr[0]['ext']['fm.ack'])    // suggested by **mario**
    echo "true";    
else {
    echo "false";   

How to read specific Json object from Json string in C#?

I wish did fix the issue. I'd recommend that you work with it as a JObject directly; this is the class you'd be using behind-the-scenes if you were using dynamic. Also, you need to separate out the selection of fmi from the normal path done in the recursive calls: here I have it in Main.
void Main()
    var resObj = JsonConvert.DeserializeObject<JObject>(jsonString);
    var result = GetKeyValuePairs((JObject)resObj["fmi"]);
private string GetKeyValuePairs(JObject resObj)
    string sDict = string.Empty;
    string fmitxt = string.Empty;
    string fmitxt2 = string.Empty;
    foreach (var pair in resObj)
      sDict += "<tr><td> " + pair.Key + "</td>";
      if (pair.Value is JObject)
        sDict += "<td>" + GetKeyValuePairs((JObject)pair.Value) + "</td></tr>";
        sDict += "<td>" + pair.Value.ToString() + "</td></tr>";
    return sDict;

Scala/Play How to use JSON read to handle JSON value that can be string or array and always return Set[String]

hop of those help? You can use the operator orElse on json Reads to create your custom reader:
val readsSet: Reads[Set[String]] = Reads.of[Set[String]].orElse(Reads.of[String].map(str => Set(str)))

val fooReads = (
  (__ \ "name").read[String] ~
  (__ \ "link").read[Set[String]](readsSet)
)(Foo.apply _)
