我需要帮助..谢谢

推荐答案
可能是我遇到了问题.问题在这里 @GET("/v1/android_tutorials/single_advance?") 你有 ? 在你的 url 的末尾，你也有@Query("advance_id") 字段表示您的请求包含两个 ?.您当前的请求看起来像这样.
Might be i got the problem.
Problem is here @GET("/v1/android_tutorials/single_advance?") you have? in the end of your url and you also have @Query("advance_id") field that mean your request contain two ?. you request currently look like this.
/v1/android_tutorials/single_advance??advance_id="xxxx"
还记得当您将 @Query("advance_id") 添加到您的请求时，默认情况下将 ? 添加到您的请求中.所以从你的 url 端删除 ? .您的网址应如下所示
Remember when you add @Query("advance_id") to your request this by default add ? to your your. So remove? from your url end. Your url should look like this
@GET("/v1/android_tutorials/single_advance")
