Loadrunner上传文件解决办法（大文件）

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!\n");

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;
