Return JSON PHP POST query

Question

I have this script in PHP, but I can’t see the result of the POST [Body]. It sends a CPF query and should return a json with the data. But nothing appears in the query.

<?php 
$array = '{ 
    "cpf_cnpj": "83899526000182"
}'; 

$json = json_encode($array);
$ch = curl_init('http://mobi.ieptb.org.br/consulta');

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

curl_setopt($ch, CURLOPT_POSTFIELDS, $json);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(

    'Content-Type: application/json',

    'Content-Length: ' . strlen($json))

);


$jsonRet = json_decode(curl_exec($ch));

?> 

It should return the following JSON (DATA I WANT TO GET):

[
{
"uf": "SC",
"codigo_cartorio": 1,
"codigo_cidade": 4205407,
"descricao": "2º TABELIONATO DE NOTAS E 1º PROTESTO DE TÍTULOS",
"endereco": "Rua Tenente Silveira, 221 , Centro - Florianópolis - SC - Telefone: 4830391991",
"telefone": "4830391991",
"data_atualizacao": "16/10/2019",
"quant_protestos": 1,
"protestos":[
{
"data_protesto": "15/05/2018",
"valor_protestado": "R$88.545,00",
"valor_protestado_o": 88545
}
]
},

Answer 1

You created this which is a string:

$array = '{ 
    "cpf_cnpj": "83899526000182"
}';

And tried applying json_encode:

$json = json_encode($array);

That is to say nay goes to Curl like this:

{ 
    "cpf_cnpj": "83899526000182"
}

Go like this:

"{ \n    \"cpf_cnpj\": \"83899526000182\"\n}"

this because simply you want a string to turn json, which has no sense, just pass the string straight, since it already has the json format:

<?php 
$json = '{ 
    "cpf_cnpj": "83899526000182"
}'; 

$ch = curl_init('http://mobi.ieptb.org.br/consulta');

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

curl_setopt($ch, CURLOPT_POSTFIELDS, $json);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(

    'Content-Type: application/json',

    'Content-Length: ' . strlen($json))

);


$jsonRet = json_decode(curl_exec($ch));

Or if you want to use an array to manipulate the value of cpf_cnpj before sending, just use an array even, example if it came from a POST:

<?php
if (empty($_POST['cpfCnpj'])) die('informe o cpf');

$array = array( 
    "cpf_cnpj" => $_POST['cpfCnpj']
);

$json = json_encode($array);

$ch = curl_init('http://mobi.ieptb.org.br/consulta');

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

curl_setopt($ch, CURLOPT_POSTFIELDS, $json);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(

    'Content-Type: application/json',

    'Content-Length: ' . strlen($json))

);

$jsonRet = json_decode(curl_exec($ch));

Another possibility is that the target server is targeting HTTPS, meaning your PHP is not configured in php.ini for secure connections, so to do this follow the tips of these answers:

• SSL error with file_get_contents

Which is basically enabling openssl in php.ini and setting up the certificate in php.ini more or less like this:

curl.cainfo = /caminho/cacert.pem

You can download the certificate on: https://curl.haxx.se/ca/cacert.pem

If you can’t or are developing something fast is to turn off the security check like this:

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

$jsonRet = json_decode(curl_exec($ch));

Of course, this will leave the data exposed to netizers halfway through, so as soon as possible set up SSL on Curl, if your hosting is having this problem then ask Helpdesk for it to enable security (but I think it is unlikely a stay without this)

Answer 2

I have a simpler method with file_get_contents. Do a test there.

<?php

    $url = 'http://mobi.ieptb.org.br/consulta';

    $body = '{"cpf_cnpj": "83899526000182"}';

    $opts = [
        'http' =>
            [
            'method'  => 'POST',
            'header'  => "Content-Type: application/json\r\n". 'Content-Length: ' . strlen($body),
            'content' => $body,
            'timeout' => 60
        ]
    ];
    $context  = stream_context_create($opts);
    $a = file_get_contents($url, false, $context, -1, 40000);
    echo '<pre>' ;
    print_r(json_decode($a));

Expected exit

[0] => stdClass Object
        (
            [uf] => SC
            [codigo_cartorio] => 1
            [codigo_cidade] => 4205407
            [descricao] => 2º TABELIONATO DE NOTAS E 1º PROTESTO DE TÍTULOS

            [telefone] => 4830391991
            [data_atualizacao] => 16/10/2019
            [quant_protestos] => 1
            [protestos] => Array
                (
                    [0] => stdClass Object
                        (
                            [data_protesto] => 15/05/2018

                        )

                )

        )
