通过请求标头发送数据与通过请求正文发送数据 [英] Sending data via request header vs sending data via request body

问题描述

通过请求标头发送数据和通过请求正文发送数据之间有什么区别.在什么情况下，我们必须通过标头/正文发送数据，什么时候不应该通过标头/正文发送数据?

What is the difference between sending data through the request header and sending data through the request body. Under what circumstances, we have to send the data through the header/body and when shouldn't we send the data through header/body ?

推荐答案

通常最好使用元数据头和业务逻辑所用数据的正文.

It is usually a good idea to use the headers for metadata and the body for the data that is used by the business logic.

需要考虑的几点:

1)如果数据是通过HTTP而不是HTTPS发送的，则代理服务器可以修改标头.

1) If the data is sent via HTTP instead of HTTPS, the proxy servers can modify the headers.

2)如果您使用REST协议在微服务之间进行通信，则互操作性可能很重要.大多数API通常不提供添加/修改自定义标头的功能.

2) If you are using the REST protocol for communication among microservices, interoperability could be important. Most APIs usually do not provide the capability to add/modify custom headers.

3)最好在HTTP标头中包含路由器/防火墙使用的数据，并将正文限制为特定于应用程序的信息.

3) It is better to have the data that is used by routers/firewalls in the HTTP header and limit the body to application specific information.
