如何在HTTP请求的标头中添加Bearer令牌? [英] How do I add a Bearer Token to the header of a HTTP request?

问题描述

我在弄清楚如何设置以授权为密钥，以承载令牌为值的授权标头时遇到麻烦.

I am having trouble figuring out how to set authorization headers with authorization as the key and a bearer token as the value.

我已经完成了内置了身份验证的Web API.我已经在邮递员上对其进行了测试，并且一切正常.问题出在邮递员上，我将令牌副本通过它传递到新的键和值，在站点中，我不确定如何在Blazor项目中更改这些值.

I have completed a web API with authentication built into it. i have tested it on postman and it all works. the problem is on post man i take the token copy past it to a new key and value, in the site i am not sure how to change those values in a Blazor project.

在 http://testapi.com/api/token/ {username}/{password}，API发送回一个代码，我需要将该代码放入标头中.

When entering a Get to the API at http://testapi.com/api/token/{username}/{password} the API sends back a code i need to take that code and put it in the header.

推荐答案

如果您使用的是服务器端Blazor @Pascal R，答案应该会带您正确的路径. 对于客户端Blazor:

If you are using a server side Blazor @Pascal R. answer should bring you to the right path. For client side Blazor:

1. 将令牌保存到您应用的全局可访问存储中.就像本地存储或级联值一样
2. 每次需要进行经过身份验证的ws调用时，都会从存储中获取令牌并将其添加为标头.

要将令牌保存在本地存储中，我建议使用:过时的本地存储.

To save the token in local storage I recommend using: Blazored Local storage.
