1.httpClient和ScrollView
1 在服務器端使用sqllite編寫數據庫
常見命令是：sqlite3 tank.db
進入之后創建表：
| create table tscore ( id integer primary key autoincrement, username varchar(32) unique not null, totalscore integer not null, score integer not null );
|
在服務器端編寫程序：
| #include<stdio.h> #include<sqlite3.h> #include<string.h> #include<stdlib.h> ? int main() ???? printf("Content-type:text/html\n\n"); ???? //set Score to Database ???? char * queryString = getenv("QUERY_STRING"); ???? if(queryString == NULL) ???? { ???????? printf("Err:queryString is NULL"); ???????? return 0; ???? } ? ???? //totalscore=%d&score=%d&user=user%d ???? //獲取參數 ???? char *totalScore = strtok(queryString,"&"); ???? char *score = strtok(NULL,"&"); ???? char *username = strtok(NULL,"&"); ? ???? strtok(totalScore,"="); ???? totalScore = strtok(NULL,"="); ? ???? strtok(score,"="); ???? score = strtok(NULL,"="); ? ???? //寫數據庫 ???? sqlite3* db; ???? int ret = sqlite3_open("/usr/lib/cgi-bin/tank.db",&db); ???? if(ret != SQLITE_OK) ???? { ???????? printf("open database error:%s",sqlite3_errstr(sqlite3_errcode(db))); ???????? return 0; ???? } ? ???? char sql[2048]; ???? sprintf(sql,"insert into tscore(username,totalScore,score) values('%s',%s,%s)",usernam|??? ??e,totalScore,score); ???? ret = sqlite3_exec(db,sql,NULL,NULL,NULL); ???? printf("%s<br>",sql); ? ???? if(ret != SQLITE_OK) ???? { printf("insert data error:%s",sqlite3_errstr(sqlite3_errcode(db))); ???????? sqlite3_close(db); ???????? return 0; ???? } ? ???? return 0; } |
| 編譯： sudo gcc setScore.c -o setScore.cgi -lsqlite3 注意要加上最后面的-lsqlite3,不然 設置tank.db的權限
