contents('php://input') returning string for JSON message
I am trying to read in a JSON message in my PHP app and this is my php code:
$json = file_get_contents('php://input');
$obj = json_decode($json, TRUE);
echo $obj->{'S3URL'};
When I do this I am getting the following error:
Trying to get property of non-object in setImage.php on line 25 (line 25 is the echo $obj->{'S3URL'}; line)
This is the request body of the request to the page:
Request Url: http://localhost:8888/setImage.php
Request Method: POST
Status Code: 200
Params: {
"S3URL": "http://url.com"
}
This is the request headers:
Accept: application/json
Content-Type: application/json
Connection: keep-alive
Origin: chrome-extension: //rest-console-id
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_1) AppleWebKit/537.36 (KHTML,
However, if I instead echo out the $json
variable I get the following:
S3URL=http%3A%2F%2Furl.com
So it looks like file_get_contents('php://input');
is reading it in as a string, and not as JSON, which will make parsing it more difficult.
Any idea why it isn't being returned as JSON, or how I can get it to be returned as JSON?
Your use of json_decode
is creating an associative array, not an object. You can treat it like an array, instead of an object. If you want an object, use this, instead:
$obj = json_decode($json);
See the documentation on the second parameter to json_decode()
:
assoc When TRUE, returned objects will be converted into associative arrays.
Also, as Johannes H. pointed out in the comments, the output of echo $json;
indicates that you are not actually receiving JSON, in the first place, so you will need to address that, as well. You asked why it isn't JSON; without seeing how you are requesting this script, it's impossible to say for sure.
The problem may be form php://input (is a read-only stream that allows you to read raw data from the request body). change some setting from php.ini , try to make "allow_url_fopen" on.
$obj = json_decode($json);
Just remove the true
