Error in OPTIONS response

[freder]

for all my requests, I get the following error (on the OPTIONS request). the actual POST request works though.

{
  "errors": [
    {
      "message": "Syntax Error GraphQL request (1:1) Unexpected <EOF>\n\n1: \n   ^\n",
      "locations": [
        {
          "line": 1,
          "column": 1
        }
      ]
    }
  ]
}

• requests are done with react-apollo
• graphql-php version: 0.11.2

update: sending the same query with graphiql works just fine. if I'm not mistaken the main difference seems to be the content-type request header:

• apollo: application/json
• graphiql: text/plain;charset=UTF-8

🤔

You should not direct OPTIONS requests to GraphQL. They are sent by browser automatically (used for cross-origin resource sharing) and have nothing to do with GraphQL. Just process OPTIONS separately as required by CORS.

@vladar I should have mentioned: was indeed talking about the automatic OPTIONS request by the browser.

could you elaborate a bit on processing OPTIONS separately – I'm not entirely sure what you mean.

thank you.

Do you use any web framework? Most of them provide some means to handle different HTTP methods separately for the same URI.

Without a framework, you can just do something like this:

if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
    // Do your CORS logic here
} else {
    $server = new GraphQL\Server\StandardServer(/* $options */);
    $server->handleRequest();
}
