http://api.aero-dev.xyz/bin/Captcha/CaptchaId.php?i=2 The server tells me "Error 400, Your browser sent an invalid request." The issue is with the x-csrf-token, when I put it as a string "x-csrf-token: j8acha7hffh" it works. When I put it as "x-csrf-token: $data" it returns an error. I have tried different ways of approaching this error. I have changed the headers. Tried different ways of requesting it. Still nothing fixes my error. I am new with PHP, please help!

CodePudding user response：

You are using the $header as an array however it contains long string as I suspect the line delimiter /r/n in the long string makes trouble here.

So change the one value array full of new line delimiters

$headers = [
    "x-csrf-token: $data\r\n".
    "Content-Type: application/json\r\n".
    "Accept: application/json\r\n"
];

to this array with multiple values

$headers = [
    "x-csrf-token: $data",
    "Content-Type: application/json",
    "Accept: application/json",
];

CURLOPT_HTTPHEADER An array of HTTP header fields to set, in the format array('Content-type: text/plain', 'Content-length: 100')

More details in https://www.php.net/manual/en/function.curl-setopt.php

Try doing this:

"x-csrf-token: ".$data."\r\n".
