Deserialization of REST request via JMS Serializer was terminated with exception "Could not decode JSON, malformed UTF-8 characters (incorrectly encoded?)". This exception is raised when PHP function json_las_error returns JSON_ERROR_UTF8 value. I spend hours of searching the cause (well formed UTF-8, BOM, etc.) with no success. UTF-8 was well defined. Then I've try change code of JMS Serializer:
class JsonDeserializationVisitor extends GenericDeserializationVisitor
{
protected function decode($str)
{
$decoded = json_decode($str, true);
switch (json_last_error()) {
case JSON_ERROR_NONE:
return $decoded;
case JSON_ERROR_DEPTH:
throw new RuntimeException('Could not decode JSON, maximum stack depth exceeded.');
case JSON_ERROR_STATE_MISMATCH:
throw new RuntimeException('Could not decode JSON, underflow or the nodes mismatch.');
case JSON_ERROR_CTRL_CHAR:
throw new RuntimeException('Could not decode JSON, unexpected control character found.');
case JSON_ERROR_SYNTAX:
throw new RuntimeException('Could not decode JSON, syntax error - malformed JSON.');
case JSON_ERROR_UTF8:
throw new RuntimeException('Could not decode JSON, malformed UTF-8 characters (incorrectly encoded?)');
default:
throw new RuntimeException('Could not decode JSON.');
}
}
}
As folows (json_last_error is not directly in switch statement):
class JsonDeserializationVisitor extends GenericDeserializationVisitor
{
protected function decode($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.');
}
}
}
After this change was deserialization terminated with success. Any explanation for this behaviour? It's a PHP bug? Thanks.
