字符串分段处理

[yel617]

在做一个嵌入式web服务器，现在要实现读取html发过来的信息，name1=value1&name2=nalue2&name2=nalue2&name3=nalue3&name4=nalue4&name5=nalue5&name6=nalue6&name7=nalue7&name8=nalue8
现在定义了2个数组，分别存放name和value
char *argName[8];
char *argValue[8];
c = getchar（）
可以怎么将c分割，分别存放在这2个数组里啊？

一一对应的数据，你定义个结构体数组来存放更合理和整齐。
至于分割，=和&不是都可以做分割标记么，自己写个字符串处理函数就可以了。

char *
skip(char **buf, const char *delimiters)
{
char *p, *begin_word, *end_word, *end_delimiters;

begin_word = *buf;
end_word = begin_word + strcspn(begin_word, delimiters);
end_delimiters = end_word + strspn(end_word, delimiters);

for (p = end_word; p < end_delimiters; p++)
*p = '\0';

*buf = end_delimiters;

return (begin_word);
}

void
parse_http_headers(char **buf, struct mg_request_info *ri)
{
int i;

for (i = 0; i < (int) ARRAY_SIZE(ri->http_headers); i++) {
ri->http_headers[i].name = skip(buf, ": ");
ri->http_headers[i].value = skip(buf, "\r\n");
if (ri->http_headers[i].name[0] == '\0')
break;
ri->num_headers = i + 1;
}
}

同意,不该让人变懒

还是说个思路让他自己写去吧,有问题再来问,思路应该就是二楼的了
