C语言将字符串转json

示例代码:

#include 
#include 
#include 

char *strrpc(char *str,char *oldstr,char *newstr){
	/*
		将一个字符串中的某些字符进行替换
		str 需要替换的字符串
		oldstr 旧的字符串
		newstr 新的字符串 	  
	*/ 
    char bstr[strlen(str)];//转换缓冲区
    memset(bstr,0,sizeof(bstr));
 
    for(int i = 0;i < strlen(str);i++){
        if(!strncmp(str+i,oldstr,strlen(oldstr))){//查找目标字符串
            strcat(bstr,newstr);
            i += strlen(oldstr) - 1;
        }else{
        	strncat(bstr,str + i,1);//保存一字节进缓冲区
	    }
    }
 
    strcpy(str,bstr);
    return str;
} 

char *split(char * src,char * str){
	/*
		传入一个数组进行p和一个以什么进行分割的str,返回切片后的值
	*/ 
	
	int i = 0, j = 0;
    char tmp[128][128] = {0};
    char *p1 = (char *)malloc(1024);
    char joint_result[300];
 
    while((p1 = (char *)strchr(src, *str)) != NULL) //必须使用(char *)进行强制类型转换
    {
        strncpy(tmp[i], src, strlen(src) - strlen(p1));
        src = p1 + 1;
        i ++;
    }
    strncpy(tmp[i], src, strlen(src)); 
 
 	//对分割后的结果再次进行拼接 
    for(j = 0; j <= i-1; j++){  //i-1因为不需要最后一个字段 
		if (j == 0){
			sprintf(joint_result,"%s%s%s","{\"",tmp[j],"\",");
		}else if (j != (i-1)){
			sprintf(joint_result,"%s%s%s%s",joint_result,"\"",tmp[j],"\",");
		}else{
			sprintf(joint_result,"%s%s%s%s",joint_result,"\"",tmp[j],"\"}");
		}				
	}
	
	return strrpc(joint_result,"=","\":\"");//调用strrpc将字符串中的【=】替换为【":"】并return最终结果
}
 
int main (void){

	char p[] = "name=laowang&id=001&money=1888.00&birthday=201808088888";
	char str[] = "&"; //分割的字符串 
	char * result;
	
    result = split(p,str);
    printf("%s",result); //输出最终结果
 
    return 0;
}
dev-c++中执行结果:
	{"name":"laowang","id":"001","money":"1888.00"}
