Disable authentication for OPTIONS requests in Tomcat

喜夏-厌秋 提交于 2020-02-06 05:56:30
问题 I have an API protected by basic auth. When I want to make AJAX requests against the API, the browser send an OPTIONS request which doesn't carry the Authorization header so it gets rejected and thus my AJAX call is not allowed by the browser. I tried to configure Tomcat to not authenticate OPTIONS requests but I don't manage to get it work. Someone to help me to get it works? Thanks :) 回答1: I found the solution, I had to specify the list of HTTP methods on which the authentication was

谷歌浏览器cors policy跨域问题

问题 最近想在自己的电脑上写一些pixi js 的 demo, 编辑器是VScode,配置open in browser 插件,使用默认谷歌浏览器打开html之后发现因为cros policy 的问题,文件不能打开本地的图片文件。报错如下: 解决方案一 按照网上大家的建议,我在桌面上添加了谷歌浏览器的图标,修改属性: 修改完毕之后VScode默认的打开方式还是不能访问本地图片,但是将链接复制到从桌面图标处打开的浏览器中可以正常访问本地图片了。到此问题算是解决了一半,每次写完效果想在浏览器中查看时,快捷键alt + b 打开的默认浏览器模式还是不能正常访问,要把链接复制粘贴到另一个窗口才行,操作起来很是麻烦。目前还没有找到解决办法。。。。 解决方案二 方案一不是一劳永逸的方法。参考了这篇博客发现可能是VScode和open in browser插件的问题,我直接在html文件中插入本地图片是可以的,但是换了pixi js 就不行了。使用live server 插件后再打开浏览器就没问题了。问题最终使用live server 插件解决。 来源: CSDN 作者: 在养一只虎纹� 链接: https://blog.csdn.net/yutingwu816/article/details/104180030

django前后段分离之跨域问题解决

一曲冷凌霜 提交于 2020-02-04 00:28:43
最近在学django前后端分离开发时遇到一点跨域问题,笔记如下: 1,打开虚拟环境 先打开命令cmd终端,然后命令打开自己的虚拟环境workon your_ENV。 2,安装cors pip install django - cors - headers 如果习惯用pycharm开发的朋友,也可以直接在 Terminal 中安装cors,不用通过cmd打开虚拟环境。 3,将 corsheaders 配置到 项目setting.py 文件中的**INSTALLED_APPS = []**中 INSTALLED_APPS = [ . . . 'crispy_forms' , . . . 'rest_framework' , 'corsheaders' , . . . ] 4,将 corsheaders.middleware.CorsMiddleware 配置到 项目setting.py 文件中的 MIDDLEWARE = [] 中,最好放在第一位,如果不放在第一位,加载时可能会有其他的先后顺序的冲突错误, 并将 CORS_ORIGIN_ALLOW_ALL 设置为 True ,在最初的srtting.py文件中CORS_ORIGIN_ALLOW_ALL属性并没有写入,其值默认为False,所以为防止拼写错误,直接复制本文代码即可。 MIDDLEWARE = [ 'corsheaders
