Question

How Do I Get By The Basic Authentication Handshake When Using Fiddler To Test A WCF REST Service?

Solution

You need to base64 encode your username:password and then prefix it with Basic. It will end up looking something like:

Authorization: Basic VEFWSVNcZGFycmVsOg==

You then enter this in the request headers field.

Darrel, what format should the text file that I am encoding be in? It looks like when it gets decoded on the server I am getting [email protected]. I am guessing these are spaces but I don't have any leading spaces in my file.

@Code Sherpa What textfile? In the RequestBuilder tab in fiddler, there is a Request Headers textbox. Just paste your authorization header in there.

Yes, but the username:password needs to be encoded into a base64 string first... I have a utility that takes a file and outputs the contents to base 64 but am getting leading ????.

OK, the Fiddler Text Encode/Decode utility worked... I forgot about this. Thanks for your help

@Code Sherpa I had no idea about that Fiddler utility :-) Now I do!

For the record, this handy utility (which I also just discovered) is in Tools -> Text Encode/Decode....

In Fiddler 4.4.2.1 (beta) it's in Tools -> Text Wizard. :)
