Android Retrofit2 reddit 404 Not Found

Question

ich Retrofit bin mit einem Android-Client für den Reddit zu erstellen. Bei logcat, um die Toke zu bekommen ist gut, aber wenn ich versuche, die Informationen des Login-Benutzers zu bekommen, bekomme ich "404 Not Found". Hier ist meine logcat:

D/OkHttp: --> POST https://oauth.reddit.com/api/v1/me http/1.1 
D/OkHttp: Content-Length: 0 
D/OkHttp: Authorization: bearer myToken

D/OkHttp: --> END POST 
D/OkHttp: <-- 404 Not Found https://oauth.reddit.com/api/v1/me (677ms)

Answer 1

Ich finde endlich meine Lösung! Ich habe mit falschem grant_type telefoniert! Ich ändere es und jetzt funktioniert es!

Answer 2

Eine mögliche Ursache kann Ihr BASE URL sein.

Nach Retrofit 2, URL Basis darf nicht mit '/' enden.

Bitte entfernen Sie ‚/‘ von Basis-URL und eine versuchen.

In Retrofit 1,9, arbeitet es in Ordnung.

Prost !!!

Answer 3

Aufgrund der Verwendung von Http Resolve für die Auflösung des URI-Schemas Ihrer Endpunkte durch Retrofit 2.0 wird die baseurl wie diese http://hello.com und die Endpunkt-URL als/world/foo angegeben.

Sie benötigen Basis-URL http://hello.com/ und Endpunkt-URL Welt/foo zu verwenden.

Der/macht den Unterschied.

Wenn es Ihnen hilft, bitte informieren Sie mich, oder ich gebe Ihnen eine andere Lösung. Ihr Problem ist das gleiche wie dieses Problem, das ich denke: Link

und Sie können diese Fragen prüfen: Link

Answer 4

@POST("api/v1/me")

entfernen "/" auf den ersten Zeichen url weil Nachrüstung 2.0 müssen baseURL muss mit "beenden/".. Ich kann kein anderes Problem in Ihrem Code finden. Sie sollten Ihren Kopf überprüfen, ob es einen Nullwert oder die API-Link

Anruf

Answer 5

Ihre API prüfen für Endpunkt /api/v1/mePOST Methode ist

@POST("/api/v1/me") 
Call<Authorize> retrieveMyInfo(); 

Nach ihrer documentation für enpoint /api/v1/me Sie GET Anfragen verwendet werden soll.

@GET("/api/v1/me") 
Call<Authorize> retrieveMyInfo(); 

Ich habe nicht diese Lösung testen, aber es scheint die Ursache zu sein für 404, as in another post es das Problem gelöst (für Python).
