C短信接口開發(fā)示例代碼

//接口類型：短信接口//測試環(huán)境：centos7.8gcc4.8.5//測試日期：2022-01-26//使用說明：demo只包含了對接時需要的傳參和解析的核心代碼，可參考整合到自己的系統(tǒng)中，具體業(yè)務細節(jié)代碼可根據(jù)自己的需要進行調(diào)整及優(yōu)化。//linux下的編譯：gcc-otest./test.c//linux下的執(zhí)行：./test//接口類型：互億無線觸發(fā)短信接口，支持發(fā)送驗證碼短信、訂單通知短信等。//賬戶注冊：請通過該地址開通賬戶/register.html//注意事項：//（1）調(diào)試期間，請用默認的模板進行測試，默認模板詳見接口文檔；//（2）請使用APIID（查看APIID請登錄用戶中心->驗證碼短信->產(chǎn)品總覽->APIID）及APIkey來調(diào)用接口；//（3）該代碼僅供接入互億無線短信接口參考使用，客戶可根據(jù)實際需要自行編寫；#include#include<sys/socket.h>#include<sys/types.h>#include#include#include#include#include#include#include<sys/wait.h>#include<sys/time.h>#include<netinet/in.h>#include<arpa/inet.h>#include#definehost"106."#definePORT80#defineBUFSIZE4096intmain(intargc,char**argv){intsockfd,ret,i,h,srandnum;structsockaddr_inservaddr;charstr1[4096],str2[4096],buf[BUFSIZE],*str;socklen_tlen;fd_sett_set1;structtimevaltv;if((sockfd=socket(AF_INET,SOCK_STREAM,0))<0){//創(chuàng)建套接字printf("createconnecterror!\n");//創(chuàng)建網(wǎng)絡連接失敗exit(0);};bzero(&servaddr,sizeof(servaddr));//每個字節(jié)都用0填充servaddr.sin_family=AF_INET;//使用IPv4地址servaddr.sin_port=htons(PORT);//端口if(inet_aton(host,&servaddr.sin_addr)==0){structhostent*he;he=gethostbyname(host);if(he==NULL)return-1;memcpy(&servaddr.sin_addr,he->h_addr,sizeof(structin_addr));}charipbuf[128];strncpy(ipbuf,inet_ntoa(servaddr.sin_addr),128);//將域名轉(zhuǎn)成IPif(inet_pton(AF_INET,ipbuf,&servaddr.sin_addr)<=0){printf("inet_ptonerror!\n");//創(chuàng)建網(wǎng)絡連接失敗exit(0);};if(connect(sockfd,(structsockaddr*)&servaddr,sizeof(servaddr))<0){printf("connecterror!\n");exit(0);}printf("connectsuccess!\n\n");//發(fā)送數(shù)據(jù)memset(str2,0,4096);strcat(str2,"account=xxxxxxxx&password=xxxxxxxxxxxx&mobile=139xxxxxxxx&content=您的驗證碼是：7328，請不要把驗證碼泄露給其他人。");str=(char*)malloc(128);len=strlen(str2);sprintf(str,"Content-Length:%d\r\n\r\n",len);memset(str1,0,4096);strcat(str1,"POST/webservice/sms.php?method=Submit&format=jsonHTTP/1.1\r\n");strcat(str1,"Host:");strcat(str1,host);strcat(str1,"\r\n");strcat(str1,"Content-Type:application/x-www-form-urlencoded\r\n");strcat(str1,str);strcat(str1,str2);strcat(str1,"\r\n\r\n");printf("RequestData:\n%s\n",str1);ret=write(sockfd,str1,strlen(str1));if(ret<0){printf("senddatafail！errno:%d,errmsg:'%s'\n\n",errno,strerror(errno));exit(0);}else{printf("senddatasuccess,length:%dbyte!\n\n",ret);}FD_ZERO(&t_set1);FD_SET(sockfd,&t_set1);while(1){//sleep(1);tv.tv_sec=0;tv.tv_usec=0;h=select(sockfd+1,&t_set1,NULL,NULL,&tv);printf("h:%dsec:%ldusec:%ld\n\n",h,tv.tv_sec,tv.tv_usec);if(h==0){memset(buf,0,4096);i=read(sockfd,buf,4095);if(i==0){close(sockfd);//關閉套接字printf("0.connectclose！\n");//讀取數(shù)據(jù)報文時發(fā)現(xiàn)遠端關閉return-1;}printf("ResponseData:\n%s\n",buf);close(sockfd);//關閉套接字printf("1.connectclose！\n");return1;}if(h>0){close(sockfd);//關閉套接字printf("2.connectclose！\n");return-1;};if(h<0){close(sockfd);//關閉套接字printf("3.con
