post接口_form表单上传

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 ;
 }

运行后日志如下：
