【问题描述】：
我正在尝试使用 Ion Koush 库从我的后端 API 获取一些 json。 我可以在其中一个 API 路由中成功，但在另一个我有以下答案：响应不可缓存。为了更好地理解问题，这里是代码：
Ion.with(clientSummaryActivity.this)
.load("GET",url)
.setLogging("LOG",Log.VERBOSE)
.addQuery("format","json")
.setHeader("Authorization",getIntent().getExtras().getString("token"))
.asJsonArray()
.setCallback(new FutureCallback<JsonArray>() {
@Override
public void onCompleted(Exception e, JsonArray result) {
// do stuff with the result or error
if(e != null){
Toast.makeText(clientSummaryActivity.this, "Erro na Query: " + e, Toast.LENGTH_LONG).show(); //cria balao de texto na view indicada
Log.v("Query Error2: ",""+e);
return;
}
if(result == null)
Log.v("Error: ","resultado vazio");
else
Log.v("Teste: ",""+result);
return;
}
});
}
这里是调试日志：

这是浏览器 REST 客户端获取的 Json：
{
"id_comentario": 5,
"id_venda_vendas": {
"id_venda": 139,
"id_cliente_cliente": {
"id_cliente": 22,
"nome": "nome",
"telefone": "nao_tem_ainda_layout",
"cpf": "cpf",
"endereco": "endereco",
"primeira_vez": true,
"data_nascimento": "dob",
"observacao": null,
"foto": null,
"email": "nao_tem_ainda_layout",
"id_ultima_compra": {}
},
"id_loja_loja": {
"id_loja": 2,
"nome": "nome",
"nome_fantasia": "nomefantasia",
"cnpj": "cnpj"
},
"data": "2016-11-18",
"hora": "15:36:02"
},
"id_funcionario_funcionario": {
"id_funcionario": 2,
"nome": "nome",
"cargo": "cargo"
},
"id_tipo_comentario_tipo_comentario": {
"id_tipo_comentario": 2,
"tipo": "Tipo"
},
"descricao": "nao tem descricao"
}
]
关键是，为什么我可以从 REST 客户端获取它，而 Ion 却说 Response 不可缓存？又是什么意思？
OBS：我可以从其他查询中获得成功的结果。不过因为篇幅太长，这里就不贴了。
