我们为什么要学网站开发,外贸网站建设加推广,中国建设app官方下载,建设网站前需考虑哪些问题一、介绍
我们在做数据上传时#xff0c;经常会用到Okhttp的开源库#xff0c;okhttp开源库也遵循html提交的MIME数据格式。
所以我们经常会看到applicaiton/json这样的格式在传。
但是如果涉及到其他文件等就需要详细的数据格式#xff0c;否则服务端无法解析
二、okHt…一、介绍

二、okHttp的MediaType类型
MediaType是指媒介类型在官方源码中有这样的描述 我们通过okhttp所有的post提交都是需要指定mime数据格式的否则导致服务端无法解析等
2.1RequestBody
在okhttp中请求是通过RequestBody来完成封装额外的数据封装RequestBody也可以多层封装将一些文件等通过RequestBody进行二次封装。但是任务都需要格式
RequestBody.create(mediaType, file) 三、MIME类型
通过上面的介绍我们知道post提交需要MIME指定的类型
