: The problem I have is if I try to parse this response in *php *using
: *json_decode()* I get a syntax error because of the '*\n*' s that are in
: the response. I could escape the before doing the *json_decode() *or at the
: point of submitting to the index but this seems wrong...
I don't really know anything about PHP, but i managed to muddle my way
through both of the little experiments below and couldn't reporoduce any
error from json_decode when the response contains "\n" (ie: the two byte
sequence represnting an escaped newline character) inside of a JSON
string, but i do get the expected error if a literal, one byte, newline
character is in the string. (something that Solr doesn't do)
are you sure when you fetch the data from Solr you aren't pre-parsing it
in some what that's evaluating hte "\n" and converting it to a real
newline?
: I am probably doing something silly and a good nights sleep will reveal
: what I am doing wrong ;-)
Good luck.
### Experiment #1, locally crated strings, one bogus json
hossman@frisbee:~$ php -a
Interactive shell
php > $valid = '{"id": "newline: (\n)"}';
php > $bogus = "{\"id\": \"newline: (\n)\"}";
php > var_dump($valid);
string(23) "{"id": "newline: (\n)"}"
php > var_dump($bogus);
string(22) "{"id": "newline: (
)"}"
php > var_dump(json_decode($valid));
object(stdClass)#1 (1) {
["id"]=>
string(12) "newline: (
)"
}
php > var_dump(json_decode($bogus));
NULL
php > var_dump(json_last_error());
int(4)
