Re: Discuss Amazon API Signed Request Helper 6 years 9 months ago #85

Hi,

This code works great but I get sometimes 403 error (Forbidden) when sending some request like
for example when I'm querying Amazon with the ISBN number of a book (ex: ISBN: 9780813343747).
Any thoughts on the probable causes of the problem ?

Do you get this error consistencly for a particular ISBN or it just appears randomly? I am aware of such error when you try to access Amazon Web Services too frequently within short period of time. But if it happens just for particular ISBN means it is restricted.

Found and fixed a big bug.
In your PercentEncodeRfc3986 method, you need to set str = str.Replace(...).
The Replace method just returns a string. You need to set it back to itself for all the replace methods to stick. Also, all "+" need to be replaced with "%20"
