我尝试使用Retrofit2向Neo4j服务器发送请求。
服务界面如下所示：
Retrofit client = new Retrofit.Builder()
.baseUrl(Globals.BASE_CLIENT_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
PhonebookContactAPI service = client.create(PhonebookContactAPI.class);
Call<List<PhonebookContact>> call = service.getContacts("PhoneBook");
call.enqueue(new Callback<List<PhonebookContact>>() {
@Override
public void onResponse(Call<List<PhonebookContact>> call, Response<List<PhonebookContact>> response) {
Log.d("Call request", call.request().toString());
Log.d("Response raw", String.valueOf(response.raw().body()));
Log.d("Response code", String.valueOf(response.code()));
if(response.isSuccessful()) {
Log.d("Response body", new Gson().toJson(response.body()));
}
else {
Log.d("Response errorBody", String.valueOf(response.errorBody()));
}
}
@Override
public void onFailure(Call<List<PhonebookContact>> call, Throwable t) {
Log.d("onFailure", t.toString());
}
});
当我致电该服务时：
05-15 18:51:58.777 D/Call request: Request{method=GET, url=http://myneo4jserver.com/db/data/label/PhoneBook/nodes, tag=null}
05-15 18:51:58.777 D/Response raw: retrofit2.OkHttpCall$NoContentResponseBody@aec27d4
05-15 18:51:58.777 D/Response code: 200
05-15 18:51:58.791 D/Response body: [{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{}]
我收到了这个堆栈跟踪：
index('sawyer.txt',['hello','cloud','cherry','tree'])
hello 824,965
cloud 583, 16403
cherry 345, 561, 7891
tree 11, 45, 651
正如您所看到的，正文包含正确数量的项目，但它们都是空的。
有什么问题？
