从网址

Question

我从服务器获取URL输入如下：

http://10.0.0.70/distance=150/angle=60

现在如何从此URL获取距离和角度参数并将其存储到另一个变量中？

我必须在Arduino编程语言中使用它。

Answer 1

这应该有效

char str[] = "http://10.0.0.70/distance=150/angle=60";
char * pch;
char *ptr;
long ret;

pch = strchr(str,'='); // find '='
ret = strtoul(pch, &ptr, 10); // take the number after it (here ret = 150)

pch = strchr(pch+1,'='); // find the next '='
ret = strtoul(pch, &ptr, 10); // take the number after it (here ret = 60)
