通过JMS Serializer反序列化REST请求已终止，但异常＆＃34;无法解码JSON，格式错误的UTF-8字符（编码错误？）＆＃34; 。当PHP函数json_las_error返回 JSON_ERROR_UTF8 值时，会引发此异常。我花了几个小时搜索原因（格式良好的UTF-8，BOM等）没有成功。 UTF-8定义明确。然后我尝试更改JMS Serializer的代码：
class JsonDeserializationVisitor extends GenericDeserializationVisitor
{
protected function decode($str)
{
$decoded = json_decode($str, true);
switch (json_last_error()) {
case JSON_ERROR_NONE:
return $decoded;
case JSON_ERROR_DEPTH:
throw new RuntimeException('Could not decode JSON, maximum stack depth exceeded.');
case JSON_ERROR_STATE_MISMATCH:
throw new RuntimeException('Could not decode JSON, underflow or the nodes mismatch.');
case JSON_ERROR_CTRL_CHAR:
throw new RuntimeException('Could not decode JSON, unexpected control character found.');
case JSON_ERROR_SYNTAX:
throw new RuntimeException('Could not decode JSON, syntax error - malformed JSON.');
case JSON_ERROR_UTF8:
throw new RuntimeException('Could not decode JSON, malformed UTF-8 characters (incorrectly encoded?)');
default:
throw new RuntimeException('Could not decode JSON.');
}
}
}
如下所示（json_last_error不直接在switch语句中）：
class JsonDeserializationVisitor extends GenericDeserializationVisitor
{
protected function decode($str)
{
$decoded = json_decode($str, true);
$error = json_last_error();
switch ($error) {
case JSON_ERROR_NONE:
return $decoded;
case JSON_ERROR_DEPTH:
throw new RuntimeException('Could not decode JSON, maximum stack depth exceeded.');
case JSON_ERROR_STATE_MISMATCH:
throw new RuntimeException('Could not decode JSON, underflow or the nodes mismatch.');
case JSON_ERROR_CTRL_CHAR:
throw new RuntimeException('Could not decode JSON, unexpected control character found.');
case JSON_ERROR_SYNTAX:
throw new RuntimeException('Could not decode JSON, syntax error - malformed JSON.');
case JSON_ERROR_UTF8:
throw new RuntimeException('Could not decode JSON, malformed UTF-8 characters (incorrectly encoded?)');
default:
throw new RuntimeException('Could not decode JSON.');
}
}
}
此更改后反序列化成功终止。对此行为有何解释？这是一个PHP错误？感谢。
