尝试调用API(内容安全策略)时出现错误

问题描述 投票:0回答:2

尝试从已部署的网站启动get功能并出现此错误:

Refused to connect to 'https://www.themealdb.com/api/json/v2/xxx/search.php?s=apple' because it violates the following Content Security Policy directive: "default-src 'self' http://*.google-analytics.com http://www.googletagmanager.com https://*.google.com https://*.google-analytics.com https://*.googletagmanager.com https://*.gstatic.com https://*.googleapis.com https://authedmine.com https://az743702.vo.msecnd.net https://sentry.io ws://localhost:4200". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

虽然在localhost服务器上运行网站,但一切正常。

将此meta tag添加到我的index.html中,仍然收到相同的错误消息。

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' http://* 'unsafe-inline'; script-src 'self' http://* 'unsafe-inline' 'unsafe-eval'">
angular api httprequest content-security-policy httphandler

您应检查您的已部署网站正在发送哪些CSP响应标头。添加元标记只能限制CSP的总数。

而且您正在尝试连接到”。如果您的预期URL在CSP中列为白色,但由于某些原因变为空白,则可能是失败的原因。

所以,起初我为index.html页面添加了元标记,但该标记无效。之后,我创建了interceptor,以将标题添加到get函数中。有关拦截器的更多信息,请访问https://angular.io/api/common/http/HttpInterceptor

仍然无法正常工作。然后我发现在server.ts文件中有以下几行代码:

app.use(helmet());
app.use(helmet.contentSecurityPolicy({
  directives: AppConfig.cspDirectives
}));

。有关helmet的更多信息:https://www.npmjs.com/package/helmet

然后在我的app.module提供商部分中,分配了{provide: APP_CONFIG, useValue: AppConfig}配置。

这是app.config.ts文件的外观:

import {InjectionToken} from '@angular/core';

export let APP_CONFIG = new InjectionToken('app.config');

export const AppConfig: any = {
  cspDirectives: {
    defaultSrc: [
      '\'self\'',
      'http://*.google-analytics.com',
      'http://www.googletagmanager.com',
      'https://*.google.com',
      'https://*.google-analytics.com',
      'https://*.googletagmanager.com',
      'https://*.gstatic.com',
      'https://*.googleapis.com',
      'https://authedmine.com',
      'https://az743702.vo.msecnd.net',
      'https://sentry.io',
      'https://www.themealdb.com/',
      'ws:<my-webpage-url>',
    ],
    styleSrc: [
      '\'self\'',
      '\'unsafe-inline\'',
      'https://*.googleapis.com'
    ],
    scriptSrc: [
      '\'self\'',
      '\'unsafe-inline\'',
      'http://*.googletagmanager.com',
      'https://*.google-analytics.com'
    ]
  }
};
