DialogFlow (API.AI) REST with php - php

I work on DialogFlow recently and I need to send a POST to my own web services.
It's a Rest services work with Symfony et PHP.
So I tried something and it didn't work.
In the tutorial it worked with Google Cloud, but I don't want to work with it.
I changed the URL of Webhook with my own. I didn't change anything else in DialogFlow because it was good with google. There it is :
/**
* #Rest\View()
* #Rest\Post("/testDialogBot")
*/
public function testDialogBotAction( Request $request )
{
$re = "Test reponse";
$response = new Response(json_encode( array( "speech" => $re, "displayText" => $re )));
$response->headers->set('Content-Type', 'application/json');
return $response;
}
The JSON of DialogFlow return :
"status": {
"code": 206,
"errorType": "partial_content",
"errorDetails": "Webhook call failed. Error: Request timeout."
},
I'm sure it can work, I do something bad probably.
Thank's for help.

According to the official docs the response "should" have the following fields: speech, displayText, data, contextOut adn source. You are only sending speech and displayText. Maybe adding the others will do the trick.
Also, the limits stated on the docs for the response are:
Timeout for service response – 5 seconds. Data received in the
response from the service – up to 64K.
Check if your server can send the response within those parameters

Ok that's fine, you don't need every parameters. My URL was wrong and It seems that DialogFlow doesn't accept https but only http.

Posting Json data with Guzzle Client in Laravel

I am trying to post some data using a Guzzle Client Http request in Laravel. But for some reason the server respons with the message that it can't find the property Id in the JSON object, while the property Id is clearly in the request. The Guzzle documentation says that assigning the array to a json property in the request will result in a Json object being sent.
$url = "https://blablabla.com/api";
$key = "1234";
$data = [
'Id' => "4"
];
$response = Http::withHeaders([
"Authorization" => $key
])->post($url, [
'json' => $data
]);
Now I have tested the api in Postman and don't experience any problems. I even use the same api in a different php application using curl and it works perfect. So obviously there is something wrong with lines of code above and not with the api. I have tried different things but nothing works.. I have a feeling that the solution is so simple.. but for the last 6 hours I couldn't figure it out.. So please help before I go crazy :)
Laravel documentation on page HTTP Client says: "By default, data will be sent using the application/json content type". So you don't need to use 'json' property in post data. Just sent it directly: ->post($url, $data).

php http post response for web hook

I'm trying to create a web hook notification. The documentation of the service i want to use requires that i specify a URL where POST requests can be performed. This URL will receive the following object, in json format, and must respond with a Status Code between 200-299.
{
"type": "ping"
}
I don't know how to proceed making my server on localhost respond with a 200 status code. http_response_code(200) works well on live server but nothing seem to be happening on localhost.
Is there any way i can make it work with localhost?
I've included the link to the documentation here (i hope it's not against the rule).
I am thinking that you wouldn't have to send them the response. The webhook would know about the response. If it reached your URL successfully, it would be a 200 OK right off the bat. If the API is requesting a response back then I imagine that you would have to call it back somehow. Is this a well-known API? Any documentation?
The response code is in the response header, not in the content.
PHP defaults to a response code of 200, so if you don't mess with it at all, you should be good.
If you want to set a different response code (202 for example), just call:
http_response_code(202);
Or set the full header yourself:
header('HTTP/1.1 202 Accepted');
Proper way to explicitly set 200 (or any other) status code with http_response_code function is just as following (don't echo or json_encode it):
http_response_code(200);
It should force webserver to use 200 status code in it's response. However, webserver could possibly ignore it. To check what response code your webserver sends, use telnet or any REST tool like Postman

How to create a Webhook server like Telegram Webhook

I need to create a Webhook server like Telegram Webhook server.
I googled it but didn't find any resources!
I'm not talking about receiving Webhook requests. I'm talking about creating a complete Webhook server to send HTTP POST requests to specific URLs. And our clients could receive the requests in their URLs by :
$response = file_get_contents('php://input');
Any helps would be great appreciated.
P.S:
Sorry for my bad English.
you can try Captain Hook laravel package, which provides you to add webhook to your laravel application
What a webhook actually does is nothing more than sending a request. The most easy way to set this up is by using Guzzle (https://packagist.org/packages/guzzlehttp/guzzle).
What you need to set up is on your side a script which decides what url to call, when that happens, just create the post request via guzzle.
$postData = [];
$client = new GuzzleHttp\Client();
$response = $client->request('POST', $url, $postData);

Error trying to create webhook

I tried to create a webhook for a task in Asana but the only response I'm getting is this:
{
"errors": [
{
"message": "Could not complete activation handshake with target URL. Please ensure that the receiving server is accepting connections and supports SSL",
"help": "For more information on API status codes and how to handle them, read the docs on errors: https://asana.com/developers/documentation/getting-started/errors"
}
]
}
(Status: 400 Bad Request)
I am sending a POST Request via Postman to https://app.asana.com/api/1.0/webhooks with following content:
{
"data":
{
"resource": 123456789012345,
"target": "https://example.com/asana.php"
}
}
The asana.php looks something like this:
$headers = getallheaders();
$secret_token = $headers['X-Hook-Secret'];
header('X-Hook-Secret: ' . $secret_token);
What am I doing wrong? Am I missing something?
According to the Asana API Reference (https://asana.com/developers/api-reference/webhooks),
The target must respond with a 200 OK and a matching X-Hook-Secret header to confirm that this webhook subscription is indeed expected.
When you send the header, do you know what response code is being sent? Perhaps you might want to have a look at the $http_response_code argument in http://php.net/manual/en/function.header.php

retrofit2 sending a PUT request method is wrong for PHP

I am trying to send a PUT request method from my Android app to my PHP endpoint but in my endpoint the PUT request is not recognized as a PUT request so I return Request method is wrong! message from my endpoint.
Android interface and request execution
Interface for activation
#PUT("device/activate.php")
Call<DeviceRegistry> registryDevice();
Executing the request
DeviceRegistryAPI registryAPI =
RetrofitController.getRetrofit().create(DeviceRegistryAPI.class);
Call<DeviceRegistry> registryCallback = registryAPI.registryDevice();
response = registryCallback.execute();
With this I am expecting a response but I am getting my endpoint error message.
My PHP endpoint
if($_SERVER['REQUEST_METHOD'] == "PUT"){
//doing something with the data
} else {
$data = array("result" => 0, "message" => "Request method is wrong!");
}
I don't know why the $_SERVER['REQUEST_METHOD'] == "PUT" is false but I wonder if I am missing something on Retrofit 2.
More Info.
I am using Retrofit2.
Update 1: Sending json into the body
I am trying to send a json using the body.
It is my json:
{
"number": 1,
"infoList": [
{
"id": 1,
"info": "something"
},
{
"id": 2,
"info": "something"
}
]
}
There are my classes:
class DataInfo{
public int number;
public List<Info> infoList;
public DataInfo(int number, List<Info> list){
this.number = number;
this.infoList = list;
}
}
class Info{
public int id;
public String info;
}
I changed the PUT interface to this:
#PUT("device/activate.php")
Call<DeviceRegistry> registryDevice(#Body DataInfo info);
But I am getting the same problem.
Update 2: Do I need Header
I have this header in my REstfull client:
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Do I need to put this on my request configuration? How do I do that if I need it?
Update 3: checking the request type of my sending post.
Now I am checking the type of the request. Because I am having the same problem with the PUT/POST requests. So If can solved the problem with the put maybe all the problems will be solved.
When I execute the request and asking and inspect the request it is sending the the type (PUT/POST) but in the server php only detect or GET?? (the below example is using POST and the behavior is the same)
Call<UpdateResponse> requestCall = client.updateMedia(downloadItemList);
Log.i("CCC", requestCall .request().toString());
And the output is a POST:
Request{method=POST, url=http://myserver/api/v1/media/updateMedia.php, tag=null}
so I am sending a POST (no matter if I send a PUT) request to the sever but why in the server I am receiving a GET. I am locked!!! I don't know where is the problem.
Update 4: godaddy hosting.
I have my php server hosting on godaddy. Is there any problem with that? I create a local host and everything works pretty good but the same code is not working on godaddy. I did some research but I didn't find any good answer to this problem so Is possible that godaddy hosting is the problem?
PHP doesn't recognize anything other than GET and POST. the server should throw at you some kind of error like empty request.
To access PUT and other requests use
$putfp = fopen('php://input', 'r'); //will be a JSON string (provided everything got sent)
$putdata = '';
while($data = fread($putfp, filesize('php://input')))
$putdata .= $data;
fclose($putfp);
//php-like variable, if you want
$_PUT = json_decode($putdata);
did not tested, but should work.
I guess the problem is that you don't pass any data along with PUT request, that's why PHP recognizes the request as a GET. So I think you just need to try to pass some data using #FormUrlEncoded, #Multipart or probably #Body annotations
To add header in your retrofit2 you should create an interceptor:
Interceptor interceptor = new Interceptor() {
#Override
public okhttp3.Response intercept(Interceptor.Chain chain) throws IOException
{
okhttp3.Request.Builder ongoing = chain.request().newBuilder();
ongoing.addHeader("Content-Type", "application/x-www-form-urlencoded");
ongoing.addHeader("Accept", "application/json");
return chain.proceed(ongoing.build());
}
};
and add it to your client builder:
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.interceptors().add(interceptor);
PHP recognises 'PUT' calls. Extracted from PHP.net:
'REQUEST_METHOD' Which request method was used to access the page;
i.e. 'GET', 'HEAD', 'POST', 'PUT'.
You don't need to send any header if your server isn't expecting any
header.
Prior to use Retrofit or any other networking library, you should check the endpoint using a request http builder, like Postman or Advanced Rest Client. To debug the request/response when running your app or unit tests use a proxy like Charles, it will help you a lot to watch how your request/response really looks.
