POST Json API by PHP

[Thibault CHAUSSON]

Hello,

I’m looking for a method to generate LaTex files by using a docker.

I found a solution proposed by latex-online on github but I encountered difficulties with the sending of the dependencies. An exemple of a dependency I’m trying to send is an image that is included in a .tex file.

Does your solution allow the sending of curl from php (see the following exemple for the code).

//https://www.codexworld.com/post-receive-json-data-using-php-curl/

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "POST https://latex.ytotech.com/builds/sync");

curl_setopt($ch, CURLOPT_POST, true);

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

    $datas = {
        "compiler": "lualatex",
        "resources": [
            {
                "main": true,
                "content": "\\documentclass{article}\n \\usepackage{graphicx}\n  \\begin{document}\n Hello World\\\\\n \\includegraphics[height=2cm,width=7cm,keepaspectratio=true]{logo.png}\n \\include{page2}\n \\end{document}"
            },
            {
                "path": "logo.png",
                "url": "https://www.ytotech.com/images/ytotech_logo.png"
            },
            {
                "path": "page2.tex",
                "file": "VGhpcyBpcyB0aGUgc2Vjb25kIHBhZ2UsIHdoaWNoIHdhcyBwYXNzZWQgYXMgYSBiYXNlNjQgZW5jb2RlZCBmaWxl"
            }
        ]
    }

curl_setopt($ch, CURLOPT_POSTFIELDS, $datas);

$response = curl_exec($ch);

curl_close($ch);

Thank you,

Yes, Curl from PHP would do, as any HTTP client.

Have you succeeded to compile a payload?

You will need to read and convert your dependency file content to base64, to include it in a entry with a property file:

{
   "resources": [
      {
          "main": true,
          "content": "\\documentclass{article} ...."
      },
      {
        "path": "image.png",
        "file": "<base64 of image>"
      }
   ]
}

Thank you for the information, I'm gonna try it now.

@thibault-chausson have you done what you wanted?

I close but you can ask again for issues or just guidance. (examples could serve others)
