Bad json array Python post request to PHP

Question

I'm trying to send a post request with Python to PHP (I'm using Phalcon PHP).

Python Code:

array_hash =["0x348eb29f3295fedc10b5b869c751fb5479585c7e65169512c3a5ff474bc0e85a", "0x63b2590119f7ea533ed93e6b2e6112410fbf49f99157bc6d7e0ce7469d3d23a8", "0xfbcdc555a3783b5cfa495ad7a5d14a159657a3f0f6b6a68583fb06ebdf984d70"]

json_data = json.dumps({"data_hash": array_hash})

requests.post(php_url, json=json_data)

My Python print array is good, I have this :

{  
   "data_hash":[  
      "0x348eb29f3295fedc10b5b869c751fb5479585c7e65169512c3a5ff474bc0e85a",
      "0x63b2590119f7ea533ed93e6b2e6112410fbf49f99157bc6d7e0ce7469d3d23a8",
      "0xfbcdc555a3783b5cfa495ad7a5d14a159657a3f0f6b6a68583fb06ebdf984d70"
   ]
}

But now when I'm trying to get it with PHP my array is empty and when I make a loop on the array I have this error :

Invalid argument supplied for foreach()

Here is my PHP code :

if($this->request->isPost()){
    error_log($this->request->getPost('data_hash')[0]);
    foreach ($this->request->getPost('data_hash') as $value) {
        error_log($value);
    }
}

But when I send just json string like this :

{"test1": "hello", "test2": "world"}

I can get it in PHP and it works. So... What is wrong with my Python array ?

You may need to use data instead of json argument with headers argument as well:

requests.post(php_url, data=json_data, headers={'Content-Type': 'application/json', 'Accept':'application/json'})

Take a look at this in requests documentation More complicated POST requests

In your PHP code you need to use the following: (as your request specifies json for the content type)

$rawBody = $this->request->getJsonRawBody(true);

Thanks for your answer. I already tried to use data but I have the same problem.

Did you add headers and you still have the same issue?

Yes I have the same issue with the headers :/

did you test with small hashes in your list?

When I remove json.dumps and headers, data_hash is not empty but it contains just the last hash as a string... not an array. I have the same error with a simple array like ['test', 'test2', 'test3']
