CURL enviando parámetros por GET: HTTP request failed! HTTP/1.1 400 Bad Request

Si al mandar un CURL por GET da el error de HTTP request failed! HTTP/1.1 400 Bad Request mandar los datos de GET de la siguiente manera:


  $ch = curl_init();

  $url = "https://loquesea";

        $dataArray = [

CURL: Ejemplos de cabeceras de CURLOPT_HTTPHEADER


$headers = array(

 'Content-type: text/plain',

 'Content-length: 100'

);



$headers = array(

    'Content-type: application/xml',

    'Authorization: gfhjui',

);



$headers = array(

 'Content-Type: text/xml'

);



$headers = array(

            "POST ".$page." HTTP/1.0",

            "Content-type: text/xml;charset='utf-8'",

            "Accept: text/xml",

            "Cache-Control: no-cache",

            "Pragma: no-cache",

            "SOAPAction: 'run'",

            "Content-length: ".strlen($xml_data),

            "Authorization: Basic " . base64_encode($credentials)

        );



$headers = array(

 'Content-Type: application/x-www-form-urlencoded'

);



$headers =  array(

 'Content-Type:application/json'

);



$headers = array(

 "Authorization: Basic".base64_encode($usuario.":".$password)

);



$User_Agent = 'Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.43 Safari/537.31';

$headers = array(

 'User-Agent: '.$User_Agent,

 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'

);



curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

CURL: autentificación básica


$url = "https://otroservidor.com/api/v3/loquesea";



$username = "xxx";

$password = "xxxx";



$headers = array(

    'Content-Type: application/json',

    'Authorization: Basic '. base64_encode("$username:$password")

);



$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_POST, false);

$result = curl_exec($ch);

curl_close($ch);

print_r($result);

Autentificación básica y cómo recibe los datos el lado del servidor para chequear que el user y el pw es el correcto:


$username = "uno";

$password = "dos";

$headers = array(

    'Content-Type: application/json',

    'Authorization: Basic '. base64_encode("$username:$password")

);

$url = "https://www.midominio.com/curl/api2.php";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_POST, false);

$result = curl_exec($ch);

curl_close($ch);

echo $result;

Y en api2.php:


echo $_SERVER['PHP_AUTH_USER']."<br>";

echo $_SERVER['PHP_AUTH_PW']."<br>";

Otra forma de hacerlo sin $headers:


$url = "https://www.midominio.com/curl/api2.php";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

curl_setopt($ch, CURLOPT_USERPWD, '111:222');

curl_setopt($ch, CURLOPT_POST, false);

$result = curl_exec($ch);

curl_close($ch);

echo $result;

Y en api2.php:


echo $_SERVER['PHP_AUTH_USER']."<br>";

echo $_SERVER['PHP_AUTH_PW']."<br>";

OJO: Algunos servidores tienen capado que puedan recibir el PHP_AUTH_USER y el PHP_AUTH_PW.

Ejemplo general con autentificación y mandando datos por post:


$username = "111";

$password = "222";

$headers = array(

    'Content-Type: application/json',

    'Authorization: Basic '. base64_encode("$username:$password")

);



$parametros = '{

  "nombre": "Pepito",

  "apellidos": "Pérez García",

  "edad": "27",

  "ciudad": "Madrid",

  "email": "pepitoperez@gmail.com"

 }';



$url = "https://www.midominio.com/curl/api2.php";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt( $ch, CURLOPT_POSTFIELDS, $parametros);

$result = curl_exec($ch);

curl_close($ch);

echo $result;

En api2.php:


header("Content-Type:application/json");

if ((isset($_SERVER['PHP_AUTH_USER'])) && (isset($_SERVER['PHP_AUTH_PW']))) {

 if (($_SERVER['PHP_AUTH_USER'] == "111") && ($_SERVER['PHP_AUTH_PW'] == "222")) {

  $data = json_decode(file_get_contents('php://input'), true);

  echo "<h1>Datos recibidos</h1>";

  print_r($data);



 }

 else {

  echo "User o PW incorrecto";

 }

}

El servidor puede tener bloqueado el acceso a determinados ficheros (por ejemplo fecha.txt) para acceder al contenido del fichero:


$username = "111";

$password = "222";

$headers = array(

    'Content-Type: application/json',

    'Authorization: Basic '. base64_encode("$username:$password")

);



$url = "https://www.midominio.com/curl/readFile.php";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_POST, false);

$result = curl_exec($ch);

curl_close($ch);

echo $result;

Y el fichero readFile.php:


header("Content-Type:application/json");

if ((isset($_SERVER['PHP_AUTH_USER'])) && (isset($_SERVER['PHP_AUTH_PW']))) {

 if (($_SERVER['PHP_AUTH_USER'] == "111") && ($_SERVER['PHP_AUTH_PW'] == "222")) {

  echo "<h1>Fichero</h1>";

  echo file_get_contents("fecha.txt");

 }

 else {

  echo "User o PW incorrecto";

 }

}

CURL: Enviar datos por JSON y cómo tratarlos en el webservice que lo recibe


$data = array(

 "num" => $_GET["num"]

);

$url = "https://otroservidor.com/pruebas/curl/test.php";

$ch = curl_init($url);

$datosJSON = json_encode($data);

curl_setopt( $ch, CURLOPT_POSTFIELDS, $datosJSON);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

$result = curl_exec($ch);

curl_close($ch);

echo $result;

Para llamarlo:
http://localhost/pruebas/curl/sendAndGet/?num=124
En test.php del otro servidor:


header("Content-Type:application/json");

$data = json_decode(file_get_contents('php://input'), true);

foreach ($data as $clave=>$valor) {

 echo "<h2>La tabla de multiplicar de ".$valor." es:</h2>";

 for ($i=1;$i<=10;$i++) {

  echo $valor." * ".$i." = ".$valor*($i)."<br>";

 }

}

Otro ejemplo:


// add User

$url = "https://otroservidor.com/pruebas/curl/add_user.php ";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

 

$parametros = '{

  "nombre": "Pepito",

  "apellidos": "Pérez García",

  "edad": "27",

  "ciudad": "Madrid",

  "email": "pepitoperez@gmail.com"

 }';



curl_setopt( $ch, CURLOPT_POSTFIELDS, $parametros);

curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_POST, true);

$result = curl_exec($ch);

curl_close($ch);

print_r($result);

en add_user.php del otro servidor:


header("Content-Type:application/json");

$data = json_decode(file_get_contents('php://input'), true);



$host_name  = "localhost";

$database   = "mibasededatos";

$user_name  = "root";

$password   = "12345678";



$cnn = mysqli_connect($host_name, $user_name, $password, $database);



if (mysqli_connect_errno()) {

 echo "ERROR AL conectar: " . mysqli_connect_error();

}

else {

}



$sql = "insert into usuarios(nombre, apellidos, edad,ciudad,email) values ('".$data["nombre"]."','".$data["apellidos"]."','".$data["edad"]."','".$data["ciudad"]."','".$data["email"]."')";

$result = mysqli_query($cnn, $sql);

En el fichero dame_datos pondrá por ejemplo:


echo "Se ha identificado el usuario ".$_POST["usuario"]." y tiene el password: ".$_POST["password"]." y pertenece a la ciudad de ".$_GET["ciudad"];

// Conectar por CURL a un FTP


$curl = curl_init();

curl_setopt($curl, CURLOPT_URL,"ftp://ftp.gnu.org");

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);



$result = curl_exec($curl);

curl_close($curl);

echo $result;

Si se quisiera acceder a un FTP que requiere usuario y contraseña sería:


ftp://usuario:pw@midominio.com // aunque no funciona en todos los navegadores

// Detectar si una ULR existe y sino que de el error


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://www.midominio.com/get_datos.php");

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_POSTFIELDS, "usuario=pepe");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);



$valido = curl_exec($ch);

 $info = curl_getinfo($ch);

 // var_dump($info);

 if ($info["http_code"] == 200) // La web existe y por tanto devuelve algo

 echo $valido;

else

 echo "ERROR: ".$info["http_code"];

curl_close($ch);

Si se envía un CURL a una url con https puede que no funcione, para que no ocurra especificar:


curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

OJO: Usar siempre curl_getinfo($ch); // te da más información de los posibles errores
