我正在使用Wordpress,将AJAX请求从网站上的表单发送到服务器,但是即使状态为200,也看不到响应消息。
页脚中的JS
var ajaxurl = '<?php echo admin_url("admin-ajax.php"); ?>';
var data = [somedata]
fetch(ajaxurl, {
method: 'POST',
headers: {
"Content-type": "application/x-www-form-urlencoded; charset=UTF-8"
},
dataType:'json',
credentials: 'include',
body: 'action=process_request&data='+data
}).then(function (result) {
console.log(result);
});
PHP
add_action('wp_ajax_process_request', 'process_request');
add_action('wp_ajax_nopriv_process_request', 'process_request');
function process_request() {
header("Content-type: application/json");
//do something with data
echo json_decode('my_response');
die();
}
服务器的响应
Response {type: "basic", url: "https://myserver.xyz/wp-admin/admin-ajax.php", redirected: false, status: 200, ok: true, …}
body: (...)
bodyUsed: false
headers: Headers {}
ok: true
redirected: false
status: 200
statusText: ""
type: "basic"
url: "https://myserver.xyz/wp-admin/admin-ajax.php"
__proto__: Response

您在 response.body 中具有响应正文。现在,您已获得有关响应的所有信息。
var ajaxurl = '<?php echo admin_url("admin-ajax.php"); ?>';
var data = [somedata]
fetch(ajaxurl, {
method: 'POST',
headers: {
"Content-type": "application/x-www-form-urlencoded; charset=UTF-8"
},
dataType:'json',
credentials: 'include',
body: 'action=process_request&data='+data
}).then(result => result.json())
.then(function (result) {
console.log(result);
});
和发送响应功能:
add_action('wp_ajax_process_request', 'process_request');
add_action('wp_ajax_nopriv_process_request', 'process_request');
function process_request() {
//do something with data
echo json_decode('{"a":1,"b":2,"c":3,"d":4,"e":5}', true);
wp_die();
}
您不能在此位置设置标题,这是行不通的。 WordPress有一个特殊的钩子。
在您的情况下:
add_action( 'send_headers', 'addHeader' );
function addHeader() {
header("Content-type: application/json");
}
以前,我忘记了将值转换为JSON,所以我编辑了答案!
问候,李子!
