  • 转:Loadrunner上传文件解决办法(大文件)

    最近再做一个跟海量存储相关的项目测试,需要通过LR模拟用户大量上传和下载文件,请求是Rest或Soap,同时还要模拟多种大小尺寸不一的文件
      通常情况下,都是使用简单的post协议即可:
      方法一:
    web_submit_data("importStudent.do",
    "Action=https://testserver/console/importStudent.do",
    "Method=POST",
    "EncType=multipart/form-data",
    "RecContentType=text/html",
    "Referer=https://testserver/console/displayStudentList.do",
    "Snapshot=t12.inf",
    "Mode=HTTP",
    ITEMDATA,
    "Name=uploadFile", "Value=D://Excel//data161955.zip", "File=yes", ENDITEM,
    LAST);
      后续对上传的文件进行MD5值比较,发现不一致,仔细查看后,发现上传的文件内容被loadrunner添加了几行额外的值,content-type等,无奈下,重写读文件的方式,我通过如下程序实现了1到10M文本文件的上传,如果上传二进制文件,body的写法有变化:
      方法二:
    vuser_init()
    {
    char fileName[] = "D:/Script/CreateObj_10M/tools.zip";
    int len = 0;
    int readLen=0;
    int tmpLen=1;
    int  runLen =104857;
    int  cLen = 0;
    if ( (file_stream = fopen(fileName, "rb")) == NULL)
    {
    lr_message("open file failed! ");
    return -1;
    }
    fseek(file_stream, 0, 2);
    len = ftell(file_stream);
    lr_message("file length is: %d bytes",  len);
    readbuf = (char *) malloc(len+1);
    memset(readbuf, 0, len+1);
    if ( runLen > len) {
    runLen = len;
    }
    fseek(file_stream, 0, 0);
    while(feof(file_stream)== 0){
    tmpLen = fread(readbuf + readLen, 1,runLen , file_stream);
    readLen += tmpLen;
    cLen = readLen + runLen;
    if (cLen > len) {
    runLen = cLen - len;
    }
    if (tmpLen==0) {
    break;
    }
    }
    //关闭文件句柄
    fclose(file_stream);
    //保存参数
    lr_save_string(readbuf,"bodys");
    }
    Action()
    {
    lr_start_transaction("CreateObj_1M");
    web_add_header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8..");
    web_add_header("Content-Type", "text/plain; charset=UTF-8");
    web_add_header("Authorization", "YWS {userkey}:XXXXXXX");
    web_custom_request("CreateObj",
    "URL=http://smartstorage{id}.yoyoyws.com:38080/test00bucket00/{IterationNum}-10M",
    "Method=PUT",
    "TargetFrame=",
    "Resource=0",
    "RecContentType=application/xml",
    "Referer=",
    "Mode=HTML",
    "Body={bodys}",       //如果是二进制文件,可以改成BodyBinary
    LAST );
    returnCode = web_get_int_property(HTTP_INFO_RETURN_CODE);
    if ( returnCode!=201 ) {
    lr_end_transaction("CreateObj_1M",LR_FAIL);
    }else{
    lr_end_transaction("CreateObj_1M",LR_PASS);
    }
    return 0;
    }
      

      但是这个程序依然有问题,当打开是二进制文件,或者文件内容过大的时候,依然会出现文件内容不一致的问题,我后续试验后,会持续更新。
