 图片参数  －  图片名  － 类型 －－ 本地图片路径 － － 其它参数



1、在iOS开发中，图片上传的请求体非常难写，格式要求非常严格，出一点错误都会造成上传失败，或请求数据失败，先看格式：

--Boundary+72D4CD655314C423
Content-Disposition: form-data; name="uploadFile"; filename="001.png"
Content-Type:image/png
Content-Transfer-Encoding: binary

... contents of boris.png ...
--Boundary+72D4CD655314C423--
这是一个不带其他任务参数，body中只有一张图就要写成这样
分别说明一下：
--Boundary+72D4CD655314C423   // 分割符，以“--”开头，后面的字随便写，只要不写中文即可
Content-Disposition: form-data; name="uploadFile"; filename="001.png"  // 这里注明服务器接收图片的参数（类似于接收用户名的userName）及服务器上保存图片的文件名
Content-Type:image/png  // 图片类型为png
Content-Transfer-Encoding: binary  // 编码方式
  // 这里是空一行，必不可少！！
... contents of boris.png ...  // 图片数据部分
--Boundary+72D4CD655314C423--  // 分隔符后面以"--"结尾，表明结束

2、如果有其他表单数据，如传用户ID等参数，也要写成以上格式：
--Boundary+72D4CD655314C423
Content-Disposition: form-data; name="userId"
     
254
--Boundary+72D4CD655314C423
Content-Disposition: form-data; name="shopId"
     
18718
