上传文件的本质是浏览器读取本地文件的内容，以二进制数据方式传输到服务端，服务端新建一个文件，将获取到的数据复制到文件中
LR中上传操作可以通过web_submit_data函数实现，支持录制
要点：
web_add_header(“Content-type”,”multipart/form-data”)或者Enctype=“multipart/form-data”
一般情况需要加 web_add_header(“Content-Type”,”multipart/form-data”);
Action()
{
web_reg_save_param("fin_msg",
"LB=",
"RB=",
"Ord=1",
"Search=Body",
LAST); web_add_header("Content-Type","multipart/form-data"); lr_start_transaction("form-data"); //上传文件---函数 web_submit_data
web_submit_data("Attachments", "Action=http://localhost:8080/pinter/file/api/upload", "Method=POST", "EncType=multipart/form-data", "TargetFrame=", "RecContentType=text/html", "Snapshot=t5.inf", "Mode=HTML", ITEMDATA, "Name=file", "Value=C:\\a.txt", "File=yes",
ENDITEM, LAST ); lr_convert_string_encoding(lr_eval_string("{fin_msg}"), LR_ENC_UTF8, LR_ENC_SYSTEM_LOCALE, "Account"); if(strcmp(lr_eval_string("{Account}"), "上传成功") == ){
lr_end_transaction("form-data", LR_PASS); }else{
lr_end_transaction("form-data", LR_FAIL); } return ;
}
