TMultipartFormData上传文件

java写的后台，上传文件时出错。

运行时异常:Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: the request was rejected because no multipart boundary was found

解决方法：

//必须设置boundary
NetHTTPClient1->ContentType ="multipart/form-data;boundary=1";
