layui上传图片接口

mvc中

前台调用接口

 url："../upload/uploadfiles/"

 

然后开始接口

 

代码：

string a = "";

try

{

HttpFileCollection file = context.Request.Files;//获取选中的文件

for (int i = 0; i < file.Count; i++)

{

string cFileName = Path.GetFileName(file[i].FileName.Trim());

//没有扩展名的文件名

string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(file[i].FileName.Trim());

string cFileType = Path.GetExtension(file[i].FileName.Trim());

if (file == null || string.IsNullOrWhiteSpace(file[i].FileName) || file[i].ContentLength == 0 || cFileType.Length < 2)

{

a = "{"code":"0","src":"","name":"","msg":"失败"}";

context.Response.Write(a);

}

string local = "images\up";

string filePathName = string.Empty;

string localPath = Path.Combine(HttpRuntime.AppDomainAppPath, local);

string tmpName = context.Server.MapPath("../images/up/");

string tmp = file[i].FileName.Trim();

int tmpIndex = 0;

while (System.IO.File.Exists(tmpName + tmp))

{

tmp = fileNameWithoutExtension + "_" + ++tmpIndex + cFileType;

}

//不带路径最终文件名

filePathName = tmp;

if (!System.IO.Directory.Exists(localPath))

{

System.IO.Directory.CreateDirectory(localPath);

}

string localURL = Path.Combine(local, filePathName);

file[i].SaveAs(Path.Combine(local, filePathName));//保存图片

a = "{"code":"1","src":"","name":"","msg":"成功"}";

context.Response.Write(a);

}

}

catch (Exception)

{

a = "{"code":"0","src":"","name":"","msg":"上传出错"}";

context.Response.Write(a);

}
