Hello anybody know about fuel http client ?
I dont know why
fuel http header set the value as array of string instead of normal string

for example {Origin=[abc], Content-Type=[application/json] instead of {Origin=abc, Content-Type=application/json

is there any method to overide it to not use array of string?

[sitepodmatt]

if it bothers you and you know you wont have duplicated, maybe create an extesnion method with that wraps in the value in listOf<String>(v) ?

[davidasync]

@sitepodmatt is there any sample code how can I change the behaviour of listOf ?

[davidasync]

and how can I inject the extension function into fuel library ?

[gildor]

You cannot inject extension function to third party code

I’m not familiar with fuel, but what exactly wrong with array of strings instead of string? I believe it just supports multiple values separated with ; and you cannot change this behavior

[gildor]

but you can write some simple wrapper as Matt suggested

I’m not familiar with fuel, but what exactly wrong with array of strings instead of string? I believe it just supports multiple values separated with `;` and you cannot change this behavior

because the host http server cannot accept header value as array

[gildor]

because the host http server cannot accept header value as array

But how does resulting header in the request looks like? Your example above is just a header representation in code, server cannot accept header in this format too: {Origin=abc, Content-Type=application/json}, header is just a string, not even 2 strings
