我尝试使用Firebase Admin SDK创建自定义令牌。但是，如图所示导入#include <stdio.h>
#include <time.h>
#include <string.h>
#include <stdlib.h>
struct string_list {
char **items;

// Simply iterate through the list and
// print every item
for (size_t i = 0 ; i < list->count ; ++i) {
fprintf(stdout, "item[%zu] = %s\n", i + 1, list->items[i]);
}
}
struct string_list *
string_list_create(size_t size)
{
struct string_list *list;
// Allocate space for the list object
list = malloc(sizeof *list);
if (list == NULL) // ALWAYS check this
return NULL;

// (starting with `size' items)
list->items = malloc(size * sizeof *list->items);
if (list->items != NULL) {
// Update the list size because the allocation
// succeeded
list->size = size;
} else {
// Be optimistic, maybe realloc will work next time
list->size = 0;
}
// Initialize the count to 0, because
// the list is initially empty
list->count = 0;
return list;
}
int
string_list_append(struct string_list *list, const char *const string)
{
// Check if there is room for the new item
if (list->count + 1 >= list->size) {
char **items;
// Resize the array, there is no more room
items = realloc(list->items, 2 * list->size * sizeof *list->items);
if (items == NULL)
return -1;
// Now update the list

list->size += list->size;
}

// increase the `count' and copy the string
list->items[list->count++] = strdup(string);
return 0;
}
void
string_list_destroy(struct string_list *const list)
{
// `free()' does work with a `NULL' argument
// so perhaps as a principle we should too
if (list == NULL)
return;
// If the `list->items' was initialized, attempt
// to free every `strdup()'ed string

我收到了错误import * as admin from 'firebase-admin';。
我正在使用
process.binding is not supported：browserify 14.0.0：firebase ^3.6.8：firebase-admin 有关如何解决此问题的任何想法？

由于您使用的是browserify和import语法而不是node.js module require syntax，因此您可能会尝试在浏览器中使用Firebase Admin SDK。 admin SDK仅供服务器使用，不适用于最终用户访问（请参阅Add the Firebase Admin SDK to your Server页面顶部的警告）。
如果您尝试使用JavaScript SDK进行最终用户访问，请改为使用this guide。
如果您在node.js服务器上使用此功能，请尝试使用require语法：
var admin = require("firebase-admin");

我正在使用Webpack作为使用firebase-admin的Node应用程序。解决方案似乎是将Webpack配置文件中的target设置为'node'。
