Invalid Malformed URL

[nathancassano]

The path of a URL contains a colon symbol which is causing the call to fail.

Using version com.squareup.retrofit2:retrofit:2.5.0

Code:

public interface ClientApi {
    @PUT("user:email={email}/login")
    Call<ResponseBody> login(@Path("email") String email, @Body String pass);

    @PUT("./user:email={email}/login")
    Call<ResponseBody> loginRelative(@Path("email") String email, @Body String pass);
...

Regular path Stack trace:

Caused by: java.lang.IllegalArgumentException: Malformed URL. Base: https://test.com/restapi/, Relative: user:email=me@test.com/login
        at retrofit2.RequestBuilder.get(RequestBuilder.java:221)
        at retrofit2.RequestFactory.create(RequestFactory.java:111)
        at retrofit2.OkHttpCall.createRawCall(OkHttpCall.java:190)
        at retrofit2.OkHttpCall.execute(OkHttpCall.java:173)
        at Service.login(Service.java:38)

Think the code needs to treat the relative portion of the URL like an absolute URL when parsing.

Relative path Using a retaliative path annotation ./ does not solve this issue. Stack trace:

Caused by: java.lang.IllegalArgumentException: @Path parameters shouldn't perform path traversal ('.' or '..'):

can I work on this issue?

[swankjesse]

No, we need to study to learn what the correct behavior is.

Is there any news about this issue? This problem causes a version lock to 2.4.0.

Hi, any update on this?

[roshanrajaratnam]

Hi any update on this? colon in a path variable seem to be encoded as %253A instead of just %3A.

Hey can I pick this issue?

[guyferguson]

Still an isue....

[sagar392]

The following interface doesn't even exists in the repository

[guyferguson]

I am using the latest retrofit version and this issue persists. Can you specify the specific Interface you say does not exist, or would it be better for me to find teh line in retrofit that generates the error msg?

Hi, any update here. The URL with only the :stuff can be workaround with ./ but if url has Path like {foo}:bar will completely broken
