我目前正在开发一个混合应用程序,它也可以在以后通过官方公司域在常规Web浏览器中运行。后端提供RESTful API,它支持所有类型的东西:获取条目,获取用户等。请求的来源至少是测试和应用程序,而不是域本身而是localhost。
现在导致问题的原因是使用POST
,Content-Type: application/json
和JSON正文发布。在浏览器中运行以进行测试时,Chrome会执行预检OPTIONS请求。我理解为什么,没有问题。不幸的是,请求的状态总是为403 - 我认为这与HTTP状态不对应,但更多的是基于响应本身对chrome的解释。 Chrome还表示缺少Access-Control-Allow-Origin标头。以下是我可以评估的一些事实:
从OPTIONS请求返回的Postman-header:
Access-Control-Allow-Origin: *
Access-Control-Allow-Headers: X-Auth-Token, Origin, X-Requested-With, Content-Type, Accept, Authorization
Access-Control-Allow-Methods: POST, PATCH, GET, PUT, OPTIONS, DELETE
有人可以帮助解决浏览器中的预检请求失败的原因吗?为什么OPTIONS响应在浏览器和Postman中不包含相同的标题?如果您需要更多信息,请告诉我们!我没有包含代码,因为OPTIONS请求是由浏览器启动的,而不是我。
非常感谢您提前和最好的问候。
