使用经典的strtok_r 切割字符串

#include<string>
#include<string.h>
#include<stdio.h>
using namespace std;

int main(int args,char **argv){

	char data[]="/hello:a=2,b=4,c=5";
	char delim[]=":";
	char* saveptr=nullptr;
	char* sub=strtok_r(data,delim,&saveptr);
	printf("sub:%s \n",sub);

	char delim2[]=",";
	char* sub2;
	while(sub2=strtok_r(saveptr,delim2,&saveptr))
	{
        	char delim3[]="=";
		char* saveptr2=nullptr;
		char *key = strtok_r(sub2,delim3,&saveptr2);
		char* value=saveptr2;
		printf("key:%s,val:%s \n",key,value);
	}	

	
	return 0;
}

g++ testStrtok.cpp -o testStrtok 

执行 ./testStrtok
