c#调用接口上传base64编码的照片

工作中使用到的，记录一下
boundary后面的横线数量需要注意

[WebMethod]
public static string UploadCustomerLogo(string img_64)
{
   
   
    try
    {
   
   
        // 去除base64头
        string pure_base64 = img_64.Replace("data:image/jpeg;base64,","").Replace("data:image/png;base64,","").Replace("data:image/jgp;base64,","");
        // base64解码
        byte[] imgBytes = Convert.FromBase64String(pure_base64);
