java - Play Framework strips "=" from URL during a Web Services call with empty values (Resulting in a 500 error at the end point)

Question

Can you tell Play Framework to call an exact URL without messing around with the URL?

I want to do a GET Request with empty values.

However while inspecting the request done by Play, even though I have hand written an exact URL the Play Framework destroys my URL and make one up by itself.

An example would be something like:

• My handwritten request:   http://address/?id=&filter=
• Play frameworks request: http://address/?id&filter

I'm well familiar with that the equals sign is optional for empty values but this is of no interest when the endpoint exposing the rest API don't.

这与您的问题没有直接关系，但我遇到了这个谷歌线程，它解释了如何调用具有多个参数的方法......

其他情况：

GET     /nice-test/:id/:name   controllers.Application.test(id:Long,
name:String) will match /nice-test/10/james

和

GET     /ugly-test             controllers.Application.test(id:Long ?=
0, name:String ?= "") will match /ugly-test?id=10&name=james

它们都将被正确传递给同一个动作，但丑陋的情况只是......丑陋：

public static Result test(Long id, String name){
    return ok("The "+name+" has id "+id);
}

在您看来，您还应该以相同的方式为这两种情况构建 url：

<a href="@routes.Application.delete(user.id, user.name)">Show me user</a>

当我尝试 Play 时，我会在这里写更多；我希望这引发了一些想法。

将空字符串设置为值应该可以为您解决问题：

 http://address/?id=""&filter=""
