QueryTemplate Bug in 10.x

[zhangruican]

RequestTemplate template = new RequestTemplate().query("url", "{url}").query("b", "{b}");
Map<String, String> vars = Maps.newHashMap();
vars.put("url", "http://www.baidu.com/?a=1&b=2");
vars.put("b", "3");
template = template.resolve(vars);
System.out.println(template.url());  // output /?url=http:%2F%2Fwww.baidu.com%2F%3Fa=1&b=2&b=3

should /?url=http:%2F%2Fwww.baidu.com%2F%3Fa=1%26b=2&b=3
QueryTemplate use Template.parseTemplate

What exactly is the issue in the result?

[zhangruican]

an issue with URI template encoding , '&' encoding

[kdavisk6]

That is intentional. Feign will consider the value for a template variable in its entirety when resolving the template. It will also encode the entire value before substitution. I suspect the output you are looking for is:

/?url=http:%2F%2Fwww.baidu.com%2F%3Fa=1%26b=2%26b=3

If that is the case, you will need to provide the complete value as {ur}l.
