如何使用 Angular 中的 delete 方法在 body 中传递数据？

exports.handler = async (event) => { 
    const product = JSON.parse(event.body);
    let sql;
    let msg;
    let values;
   if (product.action == 'delete')  {
        sql = "UPDATE product_table SET isDeleted=1, deletedon=? WHERE product_id=?";
        msg = 'The product has been sucessfully deleted';
        values = new Date();
    } else if (product.action == 'restore') {
        sql = "UPDATE product_table SET isDeleted=0, deletedon=? WHERE product_id=?";
        msg = 'The product has been successfully restored';        
        values = null;
    }
    
    try {    
        const data = await new Promise((resolve, reject) => {
            connection.getConnection(function (err) {   
                if (err) {
                    reject(err);     
                }
            connection.query(sql, [values, product.product_id], function (err, result) {
                    if (err) {  
                        console.log("Error->" + err);     
                        reject(err);        
                    }         
                    resolve(result);  
                });     
            });  
        }); 
        
        return { 
            statusCode: 200,  
            body: JSON.stringify(msg)
        };     
    } catch (err) {    
        return {   
            statusCode: 400,   
            body: JSON.stringify(err.message) 
        };
    }
};

deleteProductData(product_id:number,action:string) {
      const header: HttpHeaders = new HttpHeaders()
          .append('Content-Type', 'application/json; charset=UTF-8')
      const httpOptions = {
          headers: header,
          body:JSON.stringify({ "product_id": product_id,"action":action })
      };    
     return this.http.delete<any>(this.productGetUrl, httpOptions);
  }
