socket協議分爲TCP、UDP兩種(區別與聯繫在此不作贅述),一種爲長鏈接、一種爲短鏈接。若是建立鏈接時在init中對應關閉鏈接在end中,則爲長鏈接;若是建立關閉鏈接都是在action則爲短鏈接。服務器
在這裏主要是對socket腳本調試過程當中遇到的問題作一下簡單記錄。socket
Q1:發送請求內容的組裝方式?ide
經常使用的有兩種,數據一種是data.ws文件中存放的,一種是直接經過函數存在參數中。函數
第一種,data.ws中直接把請求放進去就能夠了,請求內容的具體形式如(二進制、加密數據)等根據實際編寫就能夠。工具
Action() { int intConn; //鏈接成功標誌 int Count_ConnFail=0; //鏈接失敗統計 int Count_NoRecv=0; //返回報文爲空統計 int Count_Error=0; //交易失敗統計 //建立鏈接 intConn=lrs_create_socket("socket1", "TCP", "LocalHost=0", "RemoteHost=10.10.49.1:1000", LrsLastArg); lr_start_transaction ("彙總查詢"); if(intConn==0) // Socket鏈接建立成功 { lrs_set_send_timeout (120,0); // 設置發送報文的超時時間 lrs_send("socket1", "buf1", LrsLastArg); lrs_set_recv_timeout (120,0); // 設置返回報文的超時時間 lrs_receive("socket1", "buf2", LrsLastArg); //lrs_get_last_received_buffer ("socket1",&ActualBuffer,&NumofBytes); if(lrs_get_last_received_buffer_size ("socket1")<1) // 若是系統返回報文爲空 { Count_NoRecv++; lr_end_transaction("彙總查詢",LR_FAIL); lr_output_message ("返回報文爲空。爲空次數:%d",Count_NoRecv); } else { // 系統返回報文不爲空 //取ansCode:0爲成功 非0爲失敗 lrs_save_searched_string ("socket1",LRS_LAST_RECEIVED,"ansCode","LB=<ans_code>","RB=</ans_code>",1,0,-1); lr_output_message ("ansCode:%s",lr_eval_string ("<ansCode>")); //取ansInfo信息:「交易成功」即成功,其餘返回值均爲失敗 lrs_save_searched_string ("socket1",LRS_LAST_RECEIVED,"ansInfo","LB=<ans_info>","RB=</ans_info>",1,0,-1); //lr_output_message ("AnsInfo: %s",lr_eval_string("<ansInfo>")); if(strcmp(lr_eval_string("<ansCode>"),"0")==0) { lr_end_transaction ("彙總查詢",LR_PASS); lr_output_message ("交易結果:%s",lr_eval_string ("<ansInfo>")); } else { //交易失敗 Count_Error++; lr_end_transaction ("彙總查詢",LR_FAIL); //交易失敗 lr_output_message("交易結果:%s",lr_eval_string ("<ansInfo>")); lr_output_message ("交易失敗次數統計:%d",Count_Error); } } } else // Socket鏈接建立不成功 { Count_ConnFail++; lr_end_transaction ("彙總查詢",LR_FAIL); lr_output_message ("Socket 鏈接失敗! Error code=%d。鏈接失敗次數:%d",intConn,Count_ConnFail); } lrs_close_socket("socket1"); return 0; }
對應的data.ws中(buf1在這裏是必須的,這裏只截取實際報文的一部分,buf2可只指定長度)atom
;WSRData 2 1 send buf1 308 "0 601<ap><head><tr_code>900001</tr_code><corp_no><CorpNo><tr_acdt>2012" "1127</tr_acdt><tr_time>084724</tr_time><atom_tr_count>1</atom_tr_count><ch" "annel>1</channel><sign>11111111</sign><filename>No File</filename><ogl_ser" "ial_no> </ogl_serial_no><reserved> </reserved></head><body><start_date>201609<EndDay></start_date><start_time>090000</start_time><end_date></body></ap>" recv buf2 500 * //517 //"0510 <ap><head><tr_code>920201</tr_code><corp_no> </corp_no><req_no>600<" //"/req_no><ans_no>5230</ans_no><tr_acdt>20121112</tr_acdt><tr_time>085032</t" //"r_time><ans_code>0</ans_code><ans_info>交易成功</ans_info><particular_code" //">0000</particular_code><particular_code>0000</particular_code><particular_" //"info>交易成功</particular_info></head><body><field_num>7</field_num><record_num>1</record_num></body></ap>" -1
這種形式的發送數據就在data.ws中,後續對其參數化與普通的腳本沒有區別。加密
第二種,經過sprintf函數保存內容在參數中,見下例。spa
Action() { lr_start_transaction("Action_1000"); Action_1000(); lr_end_transaction("Action_1000",LR_AUTO); } Action_1000() { char szPacketContent[256]; //發送包的內容 char szRecvContent[256];//接收包的內容 int iSndPacketLen = 0; char szNumberOfBytesToRecv[256+1]; int iReceiveLen=0; int iRtn = 0; char* pReceiveBuf=NULL; char *p1=NULL; char *p2=NULL; char ResposeCode[256]; char ErrorMessage[1024]; //緩衝區清零 memset(szPacketContent,0,sizeof(szPacketContent)); memset(szRecvContent,0,sizeof(szRecvContent)); memset(szNumberOfBytesToRecv,0,sizeof(szNumberOfBytesToRecv) ); memset(ResposeCode,0,sizeof(ResposeCode)); memset(ErrorMessage,0,sizeof(ErrorMessage)); lr_think_time(1.2); //建立服務器鏈接 //****************************************** iRtn = lrs_create_socket("socket0", "TCP", "LocalHost=0","RemoteHost={IP}", LrsLastArg); //****************************************** if( 0 != iRtn ) { lr_error_message("Create TCP socket failed,code:%d",iRtn); return 0; } sprintf(szPacketContent,"%s",lr_eval_string("<TransactionCode>1000</TransactionCode>" "<IDCard>{IDCard}</IDCard>" "<Password>111111</Password>" "<Balance>10000000.00</Balance>" ) ); lr_start_transaction("1000_K"); //設置發送緩衝區 lrs_set_send_buffer("socket0", szPacketContent, 256); iRtn = lrs_send("socket0", "buf0", LrsLastArg); //將報文發送到服務器 if( 0 != iRtn ) { lr_end_transaction("1000_K",LR_FAIL); lr_error_message("Send packet failed,code:%d",iRtn); lrs_close_socket("socket0"); return 0; } #ifdef DEBUG lr_output_message("Send Bufffer is:%s",szPacketContent); lr_output_message("Send Buffer Lenght is:%d",iSndPacketLen); #endif //設置超時 lrs_set_recv_timeout(100, 0); sprintf(szNumberOfBytesToRecv,"NumberOfBytesToRecv=%d",256); //****************************************** //用lrs_receive_ex函數來收報文 iRtn=lrs_receive_ex("socket0","buf1",szNumberOfBytesToRecv,LrsLastArg); //****************************************** if( 0 != iRtn ) { lr_end_transaction("4700_KKH",LR_FAIL); lr_error_message("Receive packet failed,code:%d",iRtn); lrs_close_socket("socket0"); return 0; } //****************************************** //lrs_get_last_received_buffer函數得到收到報文的緩衝區 iRtn=lrs_get_last_received_buffer("socket0",&pReceiveBuf,&iReceiveLen); //****************************************** if( iRtn != 0 || NULL == pReceiveBuf ) { lrs_free_buffer(pReceiveBuf); lr_end_transaction("4700_KKH",LR_FAIL); lrs_close_socket("socket0"); lr_error_message("The Content of last receive buffer is NULL"); return 0; } #ifdef DEBUG // lr_output_message("The Content of last receive buffer is:\n%s",pReceiveBuf+sizeof(int)); #endif memcpy(szRecvContent,pReceiveBuf,iReceiveLen); p1=(char*)strstr(szRecvContent,"<ResponseCode>"); p2=(char*)strstr(szRecvContent,"</ResponseCode>"); if (p1==NULL ||p2==NULL) { lrs_free_buffer(pReceiveBuf); lr_end_transaction("1000_K",LR_FAIL); lrs_close_socket("socket0"); lr_error_message("can not find ResposeCode"); return 0; } memcpy(ResposeCode,p1+14,p2-p1-14); if( strcmp(ResposeCode,"000000") == 0 ) { lr_end_transaction("1000_K",LR_PASS); } else { lr_end_transaction("1000_K",LR_FAIL); p1=(char*)strstr(szRecvContent,"<ErrorMessage>"); p2=(char*)strstr(szRecvContent,"</ErrorMessage>"); memcpy(ErrorMessage,p1+14,p2-p1-14); lr_error_message("ResposeCode is : %s\n ErrorMessage is: %s",ResposeCode,ErrorMessage); } //釋放pReceiveBuf緩衝區,由於pReceiveBuf緩衝區是Loadrunner分配的,必須顯示的釋放 lrs_free_buffer(pReceiveBuf); //關閉鏈接 lrs_close_socket("socket0"); return 0; }
對應的data.ws中(無實際的buf0內容,只有buf0、buf1的長度,buf0內容在action中生成)調試
;WSRData 2 1 send buf0 256 recv buf1 256 -1
注意:code
一、請求報文的格式問題,根據實際請求來分析。報文可經過socketTool工具實際發送看看。好比請求報文每行要分行,在LR裏就須要添加\r\n。
二、若是請求報文在參數化時,沒法保證全部報文的長度是固定的。這時採起哪一種呢?第二種。好比取全部報文長度的最長值100,那直接參數定義爲100,若是實際報文長度爲80則該報文補0達到100。若是報文收發沒有問題,就能夠直接使用。
待補充。。。。。
