C 使用hiredis将带空格的多字字符串rpush到redis
我正在尝试将多字字符串rpush到redis键 但是everyword作为一个新元素被添加进来了 我怎样才能避免这种情况C 使用hiredis将带空格的多字字符串rpush到redis,c,redis,hiredis,C,Redis,Hiredis,我正在尝试将多字字符串rpush到redis键 但是everyword作为一个新元素被添加进来了 我怎样才能避免这种情况 #include <stdio.h> #include <stdlib.h> #include <string.h> #include <hiredis.h> int main(int argc, char **argv) { redisContext *c; redisReply *reply;

我希望响应是3个值，但我得到6个值，这是预期的行为。您应该使用参数占位符来生成命令。请看一下这本书 摘自hiredis源代码：
/* Format a command according to the Redis protocol. This function
* takes a format similar to printf:
*
* %s represents a C null terminated string you want to interpolate
* %b represents a binary safe string
*
* When using %b you need to provide both the pointer to the string
* and the length in bytes. Examples:
*
* len = redisFormatCommand(target, "GET %s", mykey);
* len = redisFormatCommand(target, "SET %s %b", mykey, myval, myvallen);

reply = redisCommand(c,"RPUSH mylist %s","element 0"); freeReplyObject(reply);
reply = redisCommand(c,"RPUSH mylist %s","element 1"); freeReplyObject(reply);
reply = redisCommand(c,"RPUSH mylist %s","element 2"); freeReplyObject(reply);
