Question

我正在使用改造为Reddit创建一个Android客户端。在logcat上获取toke工作正常，但是当我试图获取登录用户的信息时，我得到了＃34; 404 Not Found＆＃34;。这是我的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: User-Agent: MyRedditClient/0.1 by myusername
D/OkHttp: --> END POST
D/OkHttp: <-- 404 Not Found https://oauth.reddit.com/api/v1/me (677ms)

Answer 1

您对端点/api/v1/me的API调用是POST方法

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

根据他们http://www-stud.rbi.informatik.uni-frankfurt.de/~markus/antiword/的点/api/v1/me，您应该使用GET次请求。

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

我没有测试过该解决方案，但它似乎是404的原因，documentation它解决了问题（对于python）。

Answer 2

可能的原因之一可能是您的BASE URL。

根据Retrofit 2，基本网址不得以＆＃39; /＆＃39;结尾。

请删除＆＃39; /＆＃39;从基本URL并尝试一个。

在Retrofit 1.9中，它运行良好。

干杯!!!

Answer 3

由于Retrofit 2.0如何使用Http Resolve来解析端点的uri方案，如果你将baseurl指定为此http://hello.com，将端点URL指定为/ world / foo，它将会中断。

您需要使用基本网址http://hello.com/和端点网址world / foo。

/有所作为。

如果有帮助请通知我，否则我会给你另一个解决方案。您的问题与我认为的问题相同：Link

您可以查看此问题：Link

Answer 4

@POST("api/v1/me")

在第一个字符网址中删除“/”，因为改造2.0需要BASEURL必须以“/”结尾。我在代码中找不到其他问题。如果有任何空值，您应该检查您的标头，或者检查API链接

Answer 5

我终于找到了解决方案！我用错误的grant_type打电话！我改变它，现在它正在工作！
