Wordpress Rest API 部分显示 rest_no_route 错误

如何解决Wordpress Rest API 部分显示 rest_no_route 错误

我为我的自定义插件创建了一个自定义 API。当我添加更多 if 条件如下

if($product_maximum_qty <  $input_weight_amt){
 return new WP_Error("invalid_data",__('Product Not Found'),array( 'status' => 400 )); }

我收到 {"code":"rest_no_route","message":"No route was found matching the URL and request method","data":{"status":404}} 错误。

当我删除上面的代码时。我收到了成功响应。

add_action( 'rest_api_init','woo_weight_based_pricing_rest_api_init',10,0 );
 
  function woo_weight_based_pricing_rest_api_init() {
     
     $namespace = 'woo-weight-based-pricing-api';
     
     register_rest_route($namespace,'getproductweightprices',array('args'=>array(),array('methods' => 'POST','callback' => getproductweightprice() ),));
  }
 
 
 
 function getproductweightprice(){
     
      $json = file_get_contents('php://input');
        
      $params = json_decode($json,TRUE);
      
      $product_id=trim( $params['product_id'] );
      
      $input_weight_amt=trim( $params['input_weight_amt'] ); 
      
      if(!isset($product_id) || !$product_id){  return new WP_Error( "invalid_data",__('product_id is required'),array( 'status' => 400 ) ); }  
      
      $product_data = get_post_meta($product_id);
      
      if(!$product_data){ return new WP_Error("invalid_data",array( 'status' => 400 )); }
      
      $product_maximum_qty=isset($product_data ['wwbp_max_qty'][0]) && $product_data ['wwbp_max_qty'][0] > 0 ? $product_data ['wwbp_max_qty'][0] : 0;
      
      if (!isset($input_weight_amt) || $input_weight_amt <= 0) { return new WP_Error( "invalid_data",__('Please Enter Valid Weight'),array( 'status' => 400 ) ); }
      
      if($product_maximum_qty <  $input_weight_amt){
          
          return new WP_Error("invalid_data",array( 'status' => 400 ));
      }
      
      $product = wc_get_product($product_id);
               
      $regular_price = $product->get_price();
            
      $wastage = isset($product_data['wwbp_wastage_percentage_val'][0]) && $product_data ['wwbp_wastage_percentage_val'][0] > 0 ? $product_data ['wwbp_wastage_percentage_val'][0] : 0;
                
      $product_weight= (float)$input_weight_amt;
                            
      $exact_westage= ($wastage/100)*$product_weight;
               
      $actual_weight= $product_weight - $exact_westage;
            
      $actual_price=$regular_price*$product_weight;
               
      $actual_weight_format=number_format($actual_weight,2,'.','');
               
      $actual_price_format= wc_price($actual_price,array('decimals' =>2)); 
      
      wp_send_json_success(array('actual_weight' => $actual_weight_format,'actual_price'=>$actual_price_format));
         
 }
