please I need your help.
I am working on a plagiarism api from Prepostseo, and I have been given this parameters to invoke using cURL. Now, I know little of cURL because I have been using file_get_contents. But now I am required to only use cURL. I have searched through their documentation, no reference material or source code available, not even on Github.
Here are the parameters, I need help please, on how to implement this:
curl -X POST https://www.prepostseo.com/apis/checkSentence \
-d "key=YOUR_KEY"
-d "query=Inside that cage there was a green teddy bear"
Thanks in advance!
For future reference, you can use the https://incarnate.github.io/curl-to-php
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.prepostseo.com/apis/checkSentence");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "key=YOUR_KEY&query=Inside that cage there was a green teddy bear");
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = "Content-Type: application/x-www-form-urlencoded";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close ($ch);
echo $result;
?>
This link explains everything you need to know about how to use cURL in PHP.
The code snippet below will POST through a URL-encoded query string to the specified URL.
When the cURL call is performed, the response is assigned to the $respsonse variable, and the cURL call is closed there after.
$payload = [
'key' => 'YOUR_KEY',
'query' = 'Inside that cage there was a green teddy bear'
];
$url = "https://www.prepostseo.com/apis/checkSentence";
//set up cURL - below is a general basic set up
$ch = curl_init( $url );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
//specify your method
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
//for the body values you wish to POST through
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($payload));
//specifiy any specific headers you need here in your array
curl_setopt($ch, CURLOPT_HTTPHEADER, []);
//execute and close cURL
$response = curl_exec($ch);
curl_close($ch);
I am trying to convert the following Curl command:
curl --digest --user "username:password" --verbose --url "http://127.0.0.1/ws?graph-uri=http://localhost/dataset/import/" -X POST -T /data/datasets/foo.n3
Here is the code that appears to be ok, but that doesn't work:
$args = array();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1/ws?graph-uri=http://localhost/dataset/import/');
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);
curl_setopt($ch, CURLOPT_USERPWD, "username:password");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);
$args['graph-uri'] = curl_file_create('/data/datasets/foo.n3');
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$result = curl_exec($ch);
It seems that the file is actually not uploaded with the PHP code, but everywhere I look the usage of curl_file_create() seems good.
Try this previous answer, substituting graph-uri for file_contents. Also, you are setting "graph-uri" as both GET and POST params, which could collide, and the graph-uri GET param is not URL encoded, which could behave differently in the shell vs. PHP. So you might try the following:
http://127.0.0.1/ws?graph-uri=http%3A%2F%2Flocalhost%2Fdataset%2Fimport%2F
What's the PHP equivalent of the following CURL command?
curl -X POST -d "html=<html><body><h1 style="color: red;">Hello World!</h1>" http://example.com/post"
Try something like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/post');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
$data = array('html' => '<html><body><h1 style="color: red;">Hello World!</h1>');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$output = curl_exec($ch);
curl_close($ch);
For future reference, it'd be useful to read PHP's documentation and scout out other examples before asking this type of question.
I have the following php code
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_USERAGENT, $this->_agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->_headers);
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_VERBOSE, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
curl_setopt($ch, CURLOPT_POST, 1);
But I don't understand why is not working . The API that I'm posting the JSON to says that the parameters were not received . Is there anything wrong in my code ? I think the whole trick is on the JSON parameters... I'm not sure how to send them as I couldn't see any "nave->value" pair with the http analyzer as it usually appears in simple forms ... just that JSON code without any "name".
You can try as follows.
Basically if we have a array of data then it should be json encoded using php json_encode. And you should also add content-type in header which can be defined in curl as curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$data = array("country"=>"US","states"=>array("MHASASAS"=>"MH","XYZABABA"=>"XYZ"));
$postdata = json_encode($data);
$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
you can use this and replace with
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
use this
$Parameters = array(
'MerchantCode' => $MerchantCode,
'PriceValue' => $amount,
'ReturnUrl' => $callback,
'InvoiceNumber' => $resnum,
);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($Parameters));
If:you use post method,you should know that:
CURLOPT_POST TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.
#see http://php.net/manual/en/function.curl-setopt.php
So:you can do like this:
$ar_form = array('name'=>'PHPJungle','age'=>66,'gender'=>'male');
$poststr = http_build_query($ar_form ); # important
$options[CURLOPT_HTTPGET] = false;
$options[CURLOPT_POST] = true;
$options[CURLOPT_POSTFIELDS] = $poststr ; //default type:application/x-www-from-urlencoded
curl_setopt_array ( $ch, $options );
# #todo your other codes
This is my class I have used for a long time.The class is based on PHP cURL.
It supports GET/POST，HTTP/HTTPS.
#see https://github.com/phpjungle/iHttp/
You can post a json data with curl like so:
Using Command Prompt:
curl -X POST -H "Content-Type: application/json" -d '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}' $url
Using PHP:
$data = array("folderId"=>"1","parameters"=>array("amount"=>3,"ascending"=>false,"offset"=>0,"sort"=>"date"));
$postdata = json_encode($data);
OR
$postdata = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
You haven't set the content type, so the post data is being sent as form data. Try setting the content type to application/json.
If that doesn't work, try wrapping the json string with an array.
$link = "http://test.domain/myquery";
$json = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$postdata = json_decode($json);
echo openurl($link, $postdata);
This works as json decode converts a json string into array.
function openurl($url, $postvars = "") {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, '3');
$content = trim(curl_exec($ch));
curl_close($ch);
return $content;
}
if your API endpoint using body for send request using json data may be you can use Guzzle the doc is here doc.
use GuzzleHttp\Client;
$client = new Client();
$request = $this->client->post($url,array(
'content-type' => 'application/json'
),array());
$request->setBody($json_data);
$response = $request->send();
return $response;
hope this work.
You can do it make by steps:
$data = array(
'folderId'=>"1","parameters"=>array(
"amount"=>"3","ascending"=>false,"offset"=>0,"sort"=>"date"
)
);
$data_string = http_build_query($data);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($data));
curl_setopt($ch,CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
I don't know if you need the header. I think that by default it is already application/x-www-form-urlencode
If it doesn't work, try changing the $data values in array. Think it helps. :)
I'm not sure, that this is the solution but this works for me when posting json, change the json from
'{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}'
to
"{'folderId':'1','parameters':{'amount':3,'ascending':false,'offset':0,'sort':'date'}}"
The only change i made was the double quotes are now on the outside, that works for me but I'm obviously posting to a different server
Only other help I could offer is to download a network debugging tool such as Fiddler or Charles proxy and monitor the requests sent/received, it could be a case that something else is wrong in your code.
Hope i helped :)
first of all
please check the curl http status code
$http_code= curl_get_info($exec_res,CURL_HTTP_CODE);
then modify this request header set with post header API server add a recorder to log those request info.
I'm trying to code this in PHP:
curl -F 'access_token=123' \
-F 'message=Hello, Arjun. I like this new API.' \
https://graph.facebook.com/arjun/feed
But I have no idea how to do it...
Any ideas?
Thanks
TheBounder.
You can't execute curl like this, you must first install a PHP extension (cUrl) (look here for documentation).
Then you can do things like this:
$url="https://graph.facebook.com/arjun/feed";
$ch = curl_init();
$vars = "message=YourMessage";
if($ch === FALSE){
echo "Errore init curl";
}else{
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);
$returned = curl_exec($ch);
$returned = html_entity_decode($returned);
curl_close ($ch);
I just copied some code that i used some time ago, take it as a starting point.
