Apollo graphql android在上传文件时给出http 400错误请求错误

如何解决Apollo graphql android在上传文件时给出http 400错误请求错误

当我在windows中使用curl上传文件到graphql服务器时，结果是成功的：

curl -X POST -F query="mutation { uploadAvatar(avatar: \"avatar\")}" -F avatar=@myImage.png  http://94.182.215.114:4000/api
{"data":{"uploadAvatar":"success"}}

但是当我在 Android 中上传基于 this document 的文件时，它给出了 HTTP 400 Bad Request 错误：

上传头像.graphql：

mutation UploadAvatar($file:Upload!) {
    uploadAvatar(avatar: $file)
}

java代码：

ApolloClient apolloClient = ApolloClient.builder().serverUrl("http://94.182.215.114:4000/api")
            .okHttpClient(new OkHttpClient.Builder().addInterceptor(new AuthorizationInterceptor(this)).build())
            .build();
    UploadAvatarMutation mutation = UploadAvatarMutation.builder()
            .file(new FileUpload("image/jpeg",new FileUtils(this).getPath(resultAvatarUri)))
            .build();

    ProgressDialog progressDialog = new ProgressDialog(this);
    progressDialog.setCancelable(false);
    progressDialog.show();

    apolloClient.mutate(mutation).enqueue(new ApolloCall.Callback<UploadAvatarMutation.Data>() {
        @Override
        public void onResponse(@NotNull Response<UploadAvatarMutation.Data> response) {
            runOnUiThread(() -> {
                progressDialog.dismiss();
                new AlertDialog.Builder(LoginActivity.this,R.style.RoundedCornersDialog)
                        .setMessage(response.toString())
                        .setNegativeButton(android.R.string.ok,null)
                        .show();
            });
        }

        @Override
        public void onFailure(@NotNull ApolloException e) {
            e.printstacktrace();
            runOnUiThread(() -> {
                progressDialog.dismiss();
                new AlertDialog.Builder(LoginActivity.this)
                        .setMessage("Failure " + e.getMessage())
                        .show();
            });
        }
    });

注意：Apollo 适用于其他查询。
