The loadrunner socket script will not be recorded, write to see

Loadrunner socket script writing: [loadrunner recording script will not be used, and I don’t understand it very well, let’s write it]

1. Create a windows socket script, as shown in the figure

2. Script in Action:

 

#include "lrs.h"

Action()
{
    char *noticeReply;
    char *result;
    int rc=0;
    int receive_code;
    //建立socket
    rc=lrs_create_socket("socket0","TCP","RemoteHost=127.0.0.1:8082",LrsLastArg);
    if (0==rc) {
        lr_output_message("Socket was successfully created ");
    }
    else
    {
        lr_output_message("An error occurred while creating the socket, Error Code: %d",rc);
    }

    //Start transaction
    lr_start_transaction("socket_trans");

    //Send data
    lrs_send("socket0", "buf0", LrsLastArg); 

    //end sending
    //lrs_disable_socket("socket0", DISABLE_SEND);

    //Receive the data sent back by the server
    receive_code=lrs_receive("socket0", "buf1", LrsLastArg); 

    //Receive the return message in real time, intercept the return message, 4 characters after the 64th bit in the string, four 0000
     lrs_save_param("socket0",NULL,"noticeReply",61,4);

    // Deal with Chinese garbled characters
     lr_convert_string_encoding(lr_eval_string("<noticeReply>"),"utf-8",NULL,"result");

    //Print the message after processing Chinese garbled characters
    lr_output_message("correlation=%s", lr_eval_string("<result>"));

    //The four 0000s in the message I returned are success, so judge like this
    if (strcmp(lr_eval_string("<result>"),"0000")==0){         lr_end_transaction("socket_trans",LR_PASS);     }     else     {         lr_end_transaction("socket_trans",LR_FAIL);     }     //Close the open socket     lrs_close_socket("socket0");

    return 0;
}

3. For the example in the data.ws file, change it according to your own situation

;WSRData 2 1

send buf0 40

"00000032{'name':'zyw','address':'12345'}"

recv buf1 256

-1

4. Problems encountered.

①. After receiving the returned data, Chinese characters are garbled.

 lr_convert_string_encoding(lr_eval_string("<noticeReply>"),"utf-8",NULL,"result");

②. Acquisition of the sign to judge whether the script thing is successful, Baidu downloads this method, understand and change it

 lrs_save_param("socket0",NULL,"noticeReply",61,4);

③. Modify the message response success sign

strcmp(lr_eval_string("<result>"),"0000")==0
