Answer 1

The values are sent in the request body, in the format that the content type specifies.

(值以内容类型指定的格式在请求正文中发送。)

Usually the content type is application/x-www-form-urlencoded , so the request body uses the same format as the query string:

(通常，内容类型为application/x-www-form-urlencoded ，因此请求正文使用与查询字符串相同的格式：)

parameter=value&also=another

When you use a file upload in the form, you use the multipart/form-data encoding instead, which has a different format.

(当您使用表单上载文件时，将改用multipart/form-data编码，格式不同。)

It's more complicated, but you usually don't need to care what it looks like, so I won't show an example, but it can be good to know that it exists.

(它更复杂，但是您通常不需要关心它的外观，因此我不会显示示例，但是知道它的存在可能会很好。)
