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");
1 Action() 2 { 3 web_reg_save_param("fin_msg", 4 "LB=", 5 "RB=", 6 "Ord=1", 7 "Search=Body", 8 LAST); 9 10 web_add_header("Content-Type","multipart/form-data"); 11 12 lr_start_transaction("form-data"); 13 14 //上传文件---函数 web_submit_data 15 web_submit_data("Attachments", 16 17 "Action=http://localhost:8080/pinter/file/api/upload", 18 19 "Method=POST", 20 21 "EncType=multipart/form-data", 22 23 "TargetFrame=", 24 25 "RecContentType=text/html", 26 27 "Snapshot=t5.inf", 28 29 "Mode=HTML", 30 31 ITEMDATA, 32 33 "Name=file", 34 35 "Value=C:\a.txt", 36 37 "File=yes", 38 ENDITEM, 39 40 LAST ); 41 42 lr_convert_string_encoding(lr_eval_string("{fin_msg}"), LR_ENC_UTF8, LR_ENC_SYSTEM_LOCALE, "Account"); 43 44 45 if(strcmp(lr_eval_string("{Account}"), "上传成功") == 0){ 46 lr_end_transaction("form-data", LR_PASS); 47 48 49 }else{ 50 lr_end_transaction("form-data", LR_FAIL); 51 52 53 } 54 55 56 return 0; 57 }
运行后日志如下：
