I am completely new to Log4Javascript and the concept of logging, so please bear with me.
My current task involves sending logs to a CouchDB server using a POST request. However, I keep encountering an error from the server:
{"error":"bad_request","reason":"Document must be a JSON object"}
Alright, it seems like the issue lies in the format not being a JSON Object, which is something I can easily correct.
The challenge now is figuring out how to make this correction.
This is the code snippet I am working with:
var log = log4javascript.getLogger();
var ajaxAppender = new log4javascript.AjaxAppender(url);
var layout = new log4javascript.JsonLayout(true, false);
ajaxAppender.addHeader("Content-Type", "application/json");
ajaxAppender.setLayout(layout);
log.addAppender(ajaxAppender);
// Test the logger
log.debug(JSON.stringify("Hello world!"));
After researching, it appears that this code should send the data as a JSON object, leading me to believe it is implemented correctly.
Upon inspecting the request payload, I discovered that the formatting might be the reason for the CouchDB server's rejection:
[
{
"logger": "[anonymous]",
"timestamp": 1487961971605,
"level": "DEBUG",
"url": "url.to.couchdb",
"message": "\"Hello world!\""
}
]
The structure consists of a JSON object within an array, potentially causing the problem at hand.
Therefore, my inquiries are:
- Did I overlook any configuration settings for the
AjaxAppenderandJsonLayout? - Is there a method within log4javascript to modify the Request Payload format?
- If not, does CouchDB offer a solution where I can intercept and alter the Request Payload upon document submission, eliminating the problematic array?
Thank you for your assistance.
