英文:
why retrofit is setting previous response on reloading data?
问题
我正在开发一个应用程序，该应用程序提供一组练习或考试问题，在测试结束时，我们提供重新测试您技能的选项，但是每当用户刷新以进行重新测试时，它显示与第一次尝试中相同的响应，但如果我尝试从php文件的URL获取数据，则显示不同的数据集。
只是在想是否与缓存有关。
连接文件：
RestAdapter.Builder builder = new RestAdapter.Builder();
builder.setEndpoint("xyz.com/Android/");
builder.setLogLevel(RestAdapter.LogLevel.FULL);
builder.setClient(new OkClient(new OkHttpClient()));
RestAdapter adapter = builder.build();
return(adapter.create(SetDataToDatabase.class));
@GET("/phpFile.php")
void abc(@Query("sub") String subject, Callback
请求数据的方法：
con.abc(subject, new Callback<BeanFile>() {
@Override
public void success(BeanFile bean, Response response) {
adapter = new TestPaperAdapter(bean.data, Test.this, id, answers, attempt, choosedAnswer);
recyclerView.setAdapter(adapter);
}
@Override
public void failure(RetrofitError error) {
if (error.getKind().equals(RetrofitError.Kind.NETWORK)) {
Toast.makeText(Test.this, "No Internet connection found.", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(Test.this, error.toString(), Toast.LENGTH_SHORT).show();
}
}
});

（这是一系列日志消息，显示了应用程序的操作和响应，包括网络请求、数据获取等。）

I am working on an application which provides set of question for practice or exam and at end of test we provide an adoption to retest your skills but whenever user refresh for a retest it shows same response as in the first attempt but if I try to fetch data from phpfile url It shows different set of data
just wondering that any cache to do with this.
just ignore the URLs because of restrictions all of them are edited
Connection File
RestAdapter.Builder builder=new RestAdapter.Builder();

我正在回答自己的问题
我刚找到了一个临时解决方法，但无法找到Retrofit和Android内部发生了什么以及原因
@GET("/phpFile.php")
void abc(@Query("sub") String subject, @Query("aaaa") int x, Callback<BeanFile> testQuestion_beanCallback);
在PHP文件中，我接收了任何变量但没有使用它
Random rand = new Random();
int n = 0;
n = rand.nextInt(anyValue);
con.abc(subject, n, new Callback<BeanFile>() {
@Override
public void success(BeanFile bean, Response response) {
adapter = new TestPaperAdapter(bean.data, Test.this, id, answers, attempt, choosedAnswer);
recyclerView.setAdapter(adapter);
}
@Override
public void failure(RetrofitError error) {
if (error.getKind().equals(RetrofitError.Kind.NETWORK)) {
Toast.makeText(Test.this, "未找到网络连接。", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(Test.this, error.toString(), Toast.LENGTH_SHORT).show();
}

I am answering my own question
I just found a temporary solution but failed to find what is happening inside retrofit and android and why
@GET("/phpFile.php")
void abc(@Query("sub") String subject,@Quesry("aaaa") int x, Callback<BeanFile> testQuestion_beanCallback);
and in PHP file I received any variable but kept it unused
Random rand = new Random();
int n = 0;
n = rand.nextInt(anyValue);
con.abc(subject,n, new Callback<BeanFile>() {
@Override
public void success(BeanFile bean, Response response) {
adapter = new TestPaperAdapter(bean.data, Test.this, id, answers, attempt, choosedAnswer);
recyclerView.setAdapter(adapter);
}

你可以根据以下文档从OkHttp中调试缓存：
事件 - https://square.github.io/okhttp/events/
缓存解释 - https://square.github.io/okhttp/caching/
你可以通过像使用虚拟参数一样覆盖缓存，或者通过明确覆盖行为来进行覆盖。
https://square.github.io/okhttp/4.x/okhttp/okhttp3/-cache/
Request request = new Request.Builder()
.cacheControl(new CacheControl.Builder().noCache().build())
.url("http://publicobject.com/helloworld.txt")
.build();
英文:
You can debug caching from OkHttp by following these docs
Events - https://square.github.io/okhttp/events/
Cache explanation - https://square.github.io/okhttp/caching/
You can override caching either as you have with a fake param, or by specifically overriding the behaviour
https://square.github.io/okhttp/4.x/okhttp/okhttp3/-cache/
Request request = new Request.Builder()
.cacheControl(new CacheControl.Builder().noCache().build())
.url("http://publicobject.com/helloworld.txt")
.build();
