fetch

问题 I'm having a problem with my fetch() call not working correctly. I have a recursion method that calls itself within this function, but once it passes the if statement, the data itself is not being resolved to the .then() call below. I would like to keep the recursion method within this function. Because the system that this function is calling will change the data.result to a different result that is not null. I just don't know when that will happen, hence that is why I'm using the recursion

问题 I am trying to use fetch() API POST method in order to grab the POST data in PHP. Here is what I have tried: var x = "hello"; fetch(url,{method:'post',body:x}).then(function(response){ return response.json(); }); PHP: <?php if(isset($_GET['x'])) { $get = $_GET['x']; echo $get; } ?> Is this correct? 回答1: It depends: If you want to $_GET['x'] , you need to send the data in the querystring: var url = '/your/url?x=hello'; fetch(url) .then(function (response) { return response.text(); }) .then
