1、当 basename: “collections” 时,解码成功。如图1

2、当 basename: “collectiontitem” 时,解码失败。如图2

3、查看 解码 的代码实现
$result = json_decode($data, true);
if (json_last_error() !== \JSON_ERROR_NONE) {
$message = "Invalid json: $data".PHP_EOL;
if (function_exists('json_last_error_msg')) {
$message .= ': ' . json_last_error_msg();
}
throw new \RuntimeException($message);
}
4、先分析成功的流程,打印 json_last_error()
//var_dump($data);
$result = json_decode($data, true);
//var_dump($result);
var_dump(json_last_error());
if (json_last_error() !== \JSON_ERROR_NONE) {
//dd(json_last_error());
$message = "Invalid json: $data".PHP_EOL;
if (function_exists('json_last_error_msg')) {
$message .= ': ' . json_last_error_msg();
}
throw new \RuntimeException($message);
}

5、再分析失败的流程,打印 json_last_error(),其中一次失败的值等于 4。如图3

6、打印当值为 4 时的 $data、$result
//var_dump($data);
$result = json_decode($data, true);
//var_dump($result);
//var_dump(json_last_error());
//exit;
if (json_last_error() !== \JSON_ERROR_NONE) {
var_dump($data);
var_dump($result);
var_dump(json_last_error());
exit;
//dd(json_last_error());
$message = "Invalid json: $data".PHP_EOL;
if (function_exists('json_last_error_msg')) {
$message .= ': ' . json_last_error_msg();
}
throw new \RuntimeException($message);
}

}
}
}
}
}

7、当删除 “page”: {{ Request::query(‘page’) ?? ‘1’ }} 后,解析成功。最终分析得出原因在于 JSON_ERROR_SYNTAX 语法错误。如图4

if (json_last_error() === \JSON_ERROR_SYNTAX) {
echo 'JSON_ERROR_SYNTAX';
}
8、编辑 $data,需要将 “page”: {{ Request::query(‘page’) ?? ‘1’ }} 替换为 “”page”: {{ Request::query(‘page’) ?? ‘1’ }}”。但是,page 的值类型为 int ,现在这样已经变化为了 string 类型。最为根本的解决方案应该是想办法运行程序,将其变化为 “page”: 1 才是。如图5

$result = json_decode($data, true);
var_dump($data);
var_dump($result);
var_dump(json_last_error());
if (json_last_error() !== \JSON_ERROR_NONE) {
$message = "Invalid json: $data".PHP_EOL;
if (function_exists('json_last_error_msg')) {
$message .= ': ' . json_last_error_msg();
}
throw new \RuntimeException($message);

- ✅ Go / Gin 后端接口需要排查或优化
- ✅ WordPress 网站访问慢、报错或插件冲突
- ✅ Nginx / MySQL / Redis / Linux 服务器异常
- ✅ CDN / Cloudflare / DNS / HTTPS 配置问题
- ✅ 需要长期远程技术支持或兼职维护
