Having trouble viewing the header in devtools for $http requests?

The data in the request header is not visible to me.

Here's what I'm using:

$http.post('http://localhost/api/validate', {}, { headers: key } );

https://i.sstatic.net/yioTT.png

The form that gets passed during runtime is shown below:

https://i.sstatic.net/2Wjhc.png

I am puzzled as to why I can't see any data set in the header within the devtools. On the server side, I receive null values as well. Not sure where my mistake lies.

After reading through the comments and answers, I attempted something different, but unfortunately, it did not fix the issue.

http.post('http://localhost/api/validate',key,
    { headers: { 'Content-Type': 'aplication/json'}}
}

Unfortunately, the results remain the same :(

As requested in the comments, here's how it appears in Firefox: https://i.sstatic.net/y2gwK.png

javascriptangularjshttphttp-headers

Answer №1

It seems like the issue with the POST call lies in the second argument, which should be a data object(PARAMS). Additionally, ensure that the header is structured as follows: { headers: {key:value}

$http.post('http://localhost/api/validate',{}, { headers: {key:value}} );

For example:

   $http.post("url", requestData, {
        headers: { 'Content-Type': 'aplication/json'},

    }).success(function(responseData) {
        //do stuff with response
    });

Keep in mind:

The message "CAUTION: Provisional headers are shown." displayed in DevTools indicates that the headers visible are not the actual headers sent to the server.

If you're experiencing issues, it could be due to AdBlock causing interference. Consider disabling it and trying again.
