How to repeat Chrome requests as curl commands?


The way I did it was:

  1. Access websites when the developers tools open.
  2. Issue requests, make sure they are logged in the console.
  3. Right click on the requests, select 'Save as HAR with content', and save to a file.
  4. Then run the following php script to parse the HAR file and output the correct curls:

script:

<?php    $contents=file_get_contents('/home/elyashivl/har.har');$json = json_decode($contents);$entries = $json->log->entries;foreach ($entries as $entry) {  $req = $entry->request;  $curl = 'curl -X '.$req->method;  foreach($req->headers as $header) {    $curl .= " -H '$header->name: $header->value'";  }  if (property_exists($req, 'postData')) {    # Json encode to convert newline to literal '\n'    $data = json_encode((string)$req->postData->text);    $curl .= " -d '$data'";  }  $curl .= " '$req->url'";  echo $curl."\n";}


Don't know in which version they added this feature, but Chrome now offers a "Save as cURL" option:

You can access this by going under the Network tab of the Developer Tools, and right clicking on a XHR request


Building upon the code by ElyashivLavi, I added a file name argument, error checking when reading from the file, putting curl in verbose mode, and disabling the Accept-encoding request header, which usually results in getting back compressed output that would make it hard to debug, as well as automatic execution of curl commands:

<?phpfunction bail($msg){    fprintf(STDERR, "Fatal error: $msg\n");    exit(1);}global $argv;if (count($argv) < 2)    bail("Missing HAR file name");$fname = $argv[1];$contents=file_get_contents($fname);if ($contents === false)    bail("Could not read file $fname");$json = json_decode($contents);$entries = $json->log->entries;foreach ($entries as $entry){    $req = $entry->request;    $curl = 'curl --verbose -X '.$req->method;    foreach($req->headers as $header)    {        if (strtolower($header->name) === "accept-encoding")            continue; // avoid gzip response        $curl .= " -H '$header->name: $header->value'";    }    if (property_exists($req, 'postData'))    {        # Json encode to convert newline to literal '\n'        $data = json_encode((string)$req->postData->text);        $curl .= " -d '$data'";    }    $curl .= " '$req->url'";    echo $curl."\n";    system($curl);}
