c - sscanf 多字符串扫描

Question

我想用 sscanf 在 c 中捕获以下字符串

"1=Salam Khobi|FC93F8A120F491F3A8=Rial|F191FEA4"

但 sscanf 只用“Salam Khobi”填充 &customInput.type 和 customInputTitle[0]，而不会扫描字符串的其他部分。

 #include <stdio.h>
#include <stdlib.h>

typedef enum {
    INPUT_NUMBER = 0,
    INPUT_NORMAL = 1,
    INPUT_PASSWORD = 2,
    INPUT_PAYAMOUNT = 3,
} inputType;

typedef struct {
    char * title[2];
    char * extra[2];
    inputType type;
    unsigned minLen:6;
    unsigned maxLen:6;
    unsigned forceLen:1;
    unsigned editable:1;
    unsigned char data[100];
} lcdInput;
#define CUSTOM_INPUT_LENGTH     40
static unsigned char customInputTitle[2][CUSTOM_INPUT_LENGTH];
static unsigned char customInputExtra[2][CUSTOM_INPUT_LENGTH];
const char * payload = "1=Salam Khobi|FC93F8A120F491F3A8=Rial|F191FEA4";
#define CUSTOM_INPUT_REGX       "%d=%[^|]s|%[^=]s=%[^|]s|%s"
static lcdInput customInput = {
        .title = {&customInputTitle[0], &customInputTitle[1]},
        .extra = {&customInputExtra[0], &customInputExtra[1]},
        .type = INPUT_NORMAL,
        .editable = 1,
        .forceLen = 0,
};

int main()
{
    memset(&customInputTitle, 0, CUSTOM_INPUT_LENGTH << 1);
    memset(&customInputExtra, 0, CUSTOM_INPUT_LENGTH << 1);

    sscanf(payload, CUSTOM_INPUT_REGX,
           &customInput.type,
           &customInputTitle[0], &customInputTitle[1],
           &customInputExtra[0], &customInputExtra[1]);

    return 0;
}

Answer 1

"%d=%[^|]|%[^=]=%[^|]|%s" 是正确的格式。
