我在 Spring Cloud Security 和反应式堆栈上遇到了这个奇怪的问题。我设置了 Spring Cloud Gateway，同时，我将其设置为 RsourceServer，因此在这种情况下，所有传入请求都将从 Firebase 授予 JWT。这是我的配置的一些快照。

application.yml 设置 JWK 和 Issuer，告诉 Spring Security 如何验证 JWT。

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          jwk-set-uri: https://www.googleapis.com/service_accounts/v1/jwk/securetoken@system.gserviceaccount.com
          issuer-uri: https://securetoken.google.com/${project_name}

SecurityConfig

    @EnableWebFluxSecurity
    public class SecurityConfig {

      @Bean
      public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
        // @formatter:off
        http
            .csrf().disable()
            .authorizeExchange()
            .pathMatchers("/public").permitAll()
            .anyExchange().authenticated().and()
            .oauth2ResourceServer()
            .jwt();
        return http.build();
        // @formatter:on
      }
    }

最后是控制器

TestController 仅出于测试目的，我创建了 Controller 来检查是否设置了安全上下文。

@RestController
@Slf4j
public class TestController {

  @GetMapping("/public")
  public String getPublic() {
    if (SecurityContextHolder.getContext().getAuthentication() != null) {
      throw new …

我有一些类似fabric.js的绘图应用程序(http://fabricjs.com/freedrawing/)
我想嵌入像Photoshop这样的模糊工具(http://www.demowolf.com/tutorials/demo.php?id=1503&series = 85&format = html)

这是我的模糊功能,但是当我试图改变颜色时它工作不正常它出错了你可以看到下面的截图...

function boxBlurCanvasRGBA( id, top_x, top_y, width, height, radius, iterations ){
 if ( isNaN(radius) || radius < 1 ) return;

 radius |= 0;

 if ( isNaN(iterations) ) iterations = 1;
 iterations |= 0;
 if ( iterations > 3 ) iterations = 3;
 if ( iterations < 1 ) iterations = 1;

 var canvas  = document.getElementById( 'paper' );
 var context = canvas.getContext("2d");
 var imageData;

 try {
   try {
  imageData = context.getImageData( …

我想制作一个带有html5画布的绘图工具,它只能绘制水平和垂直线

例如,尽管我将拖动鼠标,但它必须绘制垂直或水平线.
下面我将展示一个图像,我将展示我需要的东西......

谁能给我一些代码示例？

我有一个像这样的数组字符串:

 Array
(
    [TRANSACTION_ID] => SFBT-U1005141804-18DZW
    [TRANSACTION_REFERENCE] => KRZTV
    [TRANSACTION_TYPE] => sale
    [TRANSACTION_STATUS_CODE] => SA
    [MERCHANT] => safebytes
    [AFFILIATE] =>
    [TRANSACTION_DATE] => 2014-05-10 18:04:51
    [CUSTOMER_AMOUNT] => 39.90
    [CUSTOMER_CURRENCY] => USD
    [CUSTOMER_NAME] => Robin Jennings
    [CUSTOMER_EMAIL] => nesiesurveys@aol.com
    [CUSTOMER_COUNTRY] => US
    [CUSTOMER_ADDRESS] =>
    [CUSTOMER_CITY] =>
    [CUSTOMER_REGION] => NJ
    [CUSTOMER_ZIP_POSTAL] => 07067
    [CUSTOMER_LANGUAGE] => EN
    [CUSTOMER_PHONE_NUMBER] =>
    [CUSTOMER_IP] => 96.225.124.15
    [CUSTOMER_IP_ADDRESS] => 96.225.124.15
    [PAYMENT_METHOD] => PAYPAL
    [SKU] => totalsystemcare/1pk1yr
    [ORDER_STATUS] => SUCCESS
    [NOTES] => NONE
    [PAYOUT_CURRENCY] => USD
    [PAYOUT_AMOUNT] => 36.13
    [TAXES_AMOUNT] …

我有一个阵列

dump($data);
*************************************

    array(10) {
      ["12-male"] => string(1) "2"
      ["11-male"] => string(1) "2"
      ["10-female"] => string(1) "2"
      ["16-female"] => string(1) "2"
      ["9-male"] => string(1) "2"
      ["17-male"] => string(1) "4"
      ["14-male"] => string(1) "4"
      ["15-female"] => string(1) "4"
      ["13-female"] => string(1) "5"
      ["18-female"] => string(1) "6"
    }

******************************************

我动态地从上面的数组中得到子数组

$rooms = array();
foreach ($data as $key => $value) {
    $rooms['room'.$value][] = $key;
        $rooms['room'.$value]['count'] = sizeof($rooms['room'.$value]);
}

        dump($rooms);

******************************************

我得到了这个结果

Dump => array(4) {
  ["room2"] => array(6) {             //array size=6
    [0] => …

我有一些关于串联php字符串到javascript字符串的问题...

例如:

php变量

$man = "Jamse";

并具有JavaScript功能

<script>
    if (document.getElementById("fname").value == "") {
        q = false;
        msg = <?php echo 'Please fill first name'.$formErrors['fname'].'\n' ?>;
    }
</script>

我想做这样的事可以有人帮助我吗？
