如何在php中构造graphql突变查询请求

Question

I am having the hardest time figuring out how to properly format a graphql api mutation POST request in php.

If I hard code the string and use it as the data in my POST request it works like this: '{"query":"mutation{addPlay(input: {title: \"two\"}){ properties { title } } }"}'

But if I have a php array of the input values:

$test_data = array(
  'title' => 'two'
);

I can't seem to format it correctly. json_encode also puts double quotes around the keys which graphql is rejecting with the error Syntax Error GraphQL request (1:26) Expected Name, found String .

I ultimately need a solution that will convert a larger more complex array to something usable.

Answer 1

Reformatting the query allowed me to use JSON directly.

So my new query looks like this:

$test_data = array(
  'title' => 'two'
);

$request_data = array(
  'query' => 'mutation ($input: PlayInput) { addPlay(input: $input) { properties { title } }}',
  'variables' => array(
    'input' => $test_data,
  ),
);

$request_data_json = json_encode($request_data);

Then the $request_data_json is used in a POST http request.
