使用wp rest api上传特色图片

问题描述

我正在尝试从我使用wp rest api创建的前端表单中上传特色图片，但是它不起作用..这是表单的代码

<form action="" enctype="multipart/form-data" id="form" method="post" name="form">
<div id="upload">
<input id="upload_img" name="upload_img" type="file">
</div>
<input id="submit" name="submit" type="submit" value="Upload">
</form>

点击提交后调用api，这是功能：

if (isset ( $_POST ['submit'] )) {
$api_url    = 'http://localhost:8081/api_insert/wp-json/w1/v1/test';
    $body = array (
        'product_name'  => "new test",'description'   => "test",'img' => $_FILES['upload_img'],);
    
    $args = array(
        'body'        => $body,'timeout'     => 5000,'headers'     => array(),'cookies'     => array(),); 
    
    $response = wp_remote_post( $api_url,$args );
    $body = wp_remote_retrieve_body( $response );  
    echo $body; 
    wp_die();
}

最后是API的代码：

add_action( 'rest_api_init',function () {
  register_rest_route( 'w1/v1','/test/',array(
        'methods' => 'POST','callback' => 'insertProduct'
        
      ) );
});

function insertProduct( $data ) { 
$title = $data->get_param('product_name') ; 
  $content = $data->get_param('description') ;
  $getimageFile = $data->get_param('img') ; 

 $product_post = array(
            'post_title'=>$title,'post_type'=>'products','post_content'=>$content,'post_status'=>  'publish'
          );
$the_post = wp_insert_post( $product_post );
$uploaddir = wp_upload_dir();
$file = $getimageFile['name'];
if ( wp_mkdir_p( $uploaddir['path'] ) ) {
  $uploadfile = $uploaddir['path'] . '/' . basename( $file );
}
else {
  $uploadfile = $uploaddir['basedir'] . '/' . basename( $file );
}


move_uploaded_file( $getimageFile['tmp_name'],$uploadfile );
$filename = basename( $uploadfile );


$wp_filetype = wp_check_filetype(basename($filename),null );

$attachment = array(
  'post_mime_type' => $wp_filetype['type'],'post_title' => sanitize_file_name( $filename ),'post_content' => '','post_status' => 'inherit'
);
include_once ABSPATH . 'wp-admin/includes/media.PHP';
include_once ABSPATH . 'wp-admin/includes/file.PHP';
include_once ABSPATH . 'wp-admin/includes/image.PHP';
require_once (ABSPATH . 'wp-includes/pluggable.PHP');

$attach_id = wp_insert_attachment( $attachment,$uploadfile );
$attach_data = wp_generate_attachment_Metadata( $attach_id,$uploadfile );
wp_update_attachment_Metadata( $attach_id,$attach_data );
$res2= set_post_thumbnail( $the_post,$attach_id );
}

它成功插入了帖子，但没有添加特色图片，有什么帮助吗？
