Question

当我使用浏览器下载图像时，我得到答案。

我使用相同的服务器使用Android和Retrofit2下载图像，图像完全上传，我在终端中看到了处理结果，但我在应用程序中什么也没得到。

resultCall.enqueue(new Callback<Result>() {

        @Override
        public void onResponse(Call<Result> call, Response<Result> response) {
            // Response Success or Fail
            if (response.isSuccessful()) {
                if (response.body().getResult().equals("success")) {
                    Snackbar.make(parentView, R.string.string_upload_success, Snackbar.LENGTH_LONG).show();
                    Log.i("onResponse", "File Uploaded Successfully");
                } else {
                    Snackbar.make(parentView, R.string.string_upload_fail, Snackbar.LENGTH_LONG).show();
                    Log.i("onResponse", " Something went wrong");
                }
            } else {
                Snackbar.make(parentView, R.string.string_upload_fail, Snackbar.LENGTH_LONG).show();
                Log.i("onResponse", " Something went wrong");
            }

        }

        @Override
        public void onFailure(Call<Result> call, Throwable t) {
            Log.i("onFailure", t.getMessage());
            Log.e("onFailure", Arrays.toString(t.getStackTrace()));
        }
    });

以下是错误

com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:220), 
retrofit2.converter.gson.GsonResponseBodyConverter.convert(GsonResponseBodyConverter.java:37), 
retrofit2.converter.gson.GsonResponseBodyConverter.convert(GsonResponseBodyC onverter.java:25), retrofit2.ServiceMethod.toResponse(ServiceMethod.java:116),
retrofit2.OkHttpCall.parseResponse(OkHttpCall.java:211),

java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588),
java.lang.Thread.run(Thread.java:818)

并且

java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $

结果类：

public class Result {

    @SerializedName("result")
    @Expose
    private String result;

    /**
     * @return The result
     */
    public String getResult() {
        return result;
    }

    /**
     * @param result The result
     */
    public void setResult(String result) {
        this.result = result;
    }

}

我遇到了同样的错误，主要问题

您从API获得的响应是数组格式

但你正试图进入对象格式。

检查您的响应模型。

没有得到响应retrofit2
