Currently I use this:
curl -F 'access_token=token' https://somewebsite.com/oauth/like/id
Response I receive is:
{"meta":{"code":200},"data":null}
However, I'm sending many requests at the same time, so I don't know who's response that is. I would like to get a response to something like
{'123456': {"meta":{"code":200},"data":null} }
Where 123456 is some id I send with the request. A similar solution would be really appreciated. I've done this with PHP, however I want this to work through command-line.
Thank you.
Usually when you are pinging a server you should use a callback for when the response is called.
In the callback you should know what request it was from.

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
I'm using Guzzle that I installed via composer and failing to do something relatively straightforward.
I might be misunderstanding the documentation but essentially what I'm wanting to do is run a POST request to a server and continue executing code without waiting for a response. Here's what I have :
$client = new \GuzzleHttp\Client(/*baseUrl, and auth credentials here*/);
$client->post('runtime/process-instances', [
'future'=>true,
'json'=> $data // is an array
]);
die("I'm done with the call");
Now lets say the runtime/process-instances runs for about 5mn, I will not get the die message before those 5mn are up... When instead I want it right after the message is sent to the server.
Now I don't have access to the server so I can't have the server respond before running the execution. I just need to ignore the response.
Any help is appreciated.
Things I've tried:
$client->post(/*blabla*/)->then(function ($response) {});
It is not possible in Guzzle to send a request and immediately exit. Asynchronous requests require that you wait for them to complete. If you do not, the request will not get sent.
Also note that you are using post instead of postAsync, the former is a synchronous (blocking) request. To asynchronously send a post request, use the latter. In your code example, by changing post to postAsync the process will exit before the request is complete, but the target will not receive that request.
Have you tried setting a low timeout?
So, I have this method where I need to call an external url (different domain). It's something like http://192.168.2.2:9090/send?num=100&txt=text; Is there any way to do this without using curl?
I guess I should clarify that I have tried using curl with the yii-curl extension but somehow it doesn;t seem to work. It works when I supply a whole formatted url, but if I try to modify the url with params for num and txt, it doesn't work for some reason. Preferably I am looking for a solution without curl, but if that is not possible I could use some help with how to format and execute a proper url so I can also supply params to the url. Thanks.
Edit: I don't think file_get_contents() will work as the url is actually to an SMS gateway that sends sms. the phone number and sms text is supplied as params. Let me know if I am guessing it wrong.
Edit 2: This is what I tried after the suggestions here.
public function sendTXTSMS($sentToNum,$text)
{
$construct_url="http://192.168.2.2:9090/send?num={$sentToNum}&txt={$text}";
file_get_contents($construct_url);
}
And then calling it like,
$text='Lorem ipsum dolor ........ ';
$this->sendTXTSMS(XXXXXXXXXX,$text)
XXXXXXXXXX is of course the phone number masked here.
Now I am getting an HTTP request failed! HTTP/1.1 400 Bad Request error. allow_url_fopen is enabled and I can access the url fine by typing it on a browser. Also tried using urlencode on the url.
If it's a GET request you can use file_get_contents($url);.
If you need more options you can try the HTTP library, but there's little reason to not directly use libcurl. It's standard practice.
The fact it's connecting to a service related to SMS is irrelevant. If it's a URL for a web service on a server you can connect to, you can make a request to it.
file_get_contents() will work if allow_url_fopen is enabled in php.ini, but I think your problem is this:
It works when I supply a whole formatted url, but if I try to modify
the url with params for num and txt, it doesn't work for some reason.
You need to encode the data:
$test = urlencode($text);
$sentToNum = urlencode($sentToNum);
$construct_url = "http://192.168.2.2:9090/send?num={$sentToNum}&txt={$text}";
Yes you can use file_get_contents http://php.net/manual/en/function.file-get-contents.php
Using curl should be a better option since you can easily deal with http status code...
But with or without curl, you need to build your url correctly, urlencode should be used on params, not on url :
$sentToNum = urlencode($sentToNum);
$text = urlencode($text);
$construct_url="http://192.168.2.2:9090/send?num={$sentToNum}&txt={$text}";
An API I'm trying to program to requires multipart/form-data content with the HTTP GET verb. From the command line I can make this work like this:
curl -X GET -H "Accept: application/json" -F grant_type=consumer_credentials -F consumer_key=$key -F consumer_secret=$secret https://example.com/api/AccessToken
which seems like a contradiction in terms to me, but it actually works, and from what I see tracing it actually uses GET. I've tried a bunch of things to get this working using PHP's cURL library, but I just can't seem to get it to not use POST, which their servers kick out with an error.
Update to clarify the question: how can I get php's cURL library to do the same thing as that command line?

Not exactly. curl uses a feature of the HTTP/1.1. It inserts additional field to the header Expect: 100-continue, on which, if supported by server, server should response by HTTP/1.1 100 Continue, which tells the client to continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed.
Since they are insisting on HTTP GET, then just encode the form elements into query parameters on the URL you are GETing and use cURL's standard get options instead of posting multipart/formdata.
-X will only change the method keyword, everything else will remain acting the same which in this case (with the -F options) means like multipart formpost.
-F is multipart formpost and you really cannot convert that to a query part in the URL suitable for a typical GET so this was probably not a good idea to start with.
I would guess that you actually want to use -d to specify the data to post, and then you use -G to convert that data into a string that gets appended to the URL so that the operation turns out to a nice and clean GET.
I am attempting to utilize the USPS API to do some address verification/validation.
I'm sending this XML to http://testing.shippingapis.com/ShippingAPITest.dll:
<AddressValidateRequest%20USERID="xxxxx"><Address ID="0"><Address1></Address1><Address2>6406 Ivy Lane</Address2><City>Greenbelt</City><State>MD</State><Zip5></Zip5><Zip4></Zip4></Address></AddressValidateRequest>
This is the same XML that is shown in their documentation for test requests. However, I always get an HTML (instead of XML) response that is a 501 Not Implmented error. Anyone familiar with this API know what might be going on? I'm using curl (in php) to make the request
UPDATE: When I make the request by typing the url into a browser with get params, it seems to work fine, but i get the error mentioned above using php/curl or just curl from the command line.
UPDATE: If I use file_get_contents with the url, I get a 400 bad request error - but if i urlencode, it works great - solution accepted.
Not familiar with the API, but:
Do you need the %20 after AddressValidateRequest? Does it work when that is replaced by a space?
Also, do you need to use CURL? Could you just use fopen() or file_get_contents() and then use the GET parameters which you mention work OK?
