在 PHP 中，$id 變數應該從客戶端接收一個整數值。但是，當客戶端使用POST請求方法將id值作為整數傳送到PHP腳本時，當腳本上傳到WAMP伺服器時，它會自動轉換為PHP中的字串類型。另一方面，當腳本上傳到Bluehost伺服器上時，id值仍然是整數，不會轉換為字串，這正是我想要的。
這是一個簡單的 PHP 腳本：
<?php
$id = $_POST["id"];
if (is_int($id))
echo "It is integer"; // It will print this if the PHP script was uploaded to the Bluehost server.
else if (is_string($id))
echo "It is string"; // It will print this if the PHP script was uploaded to the WAMP server.
從客戶端發送的 id 值是透過 Android 應用程式發送的，這就是我將 id 值發送到 PHP 腳本的方式：
RetrofitManager 類別
public class RetrofitManager {
private static RetrofitManager.Api api;
public static RetrofitManager.Api getApi() {
if (api == null)
api = new Retrofit.Builder()
.baseUrl("http://192.151.5.721/API/")
.client(new OkHttpClient.Builder().readTimeout(3, TimeUnit.MINUTES).writeTimeout(3, TimeUnit.MINUTES).connectTimeout(25, TimeUnit.SECONDS).build())
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava3CallAdapterFactory.create())
.build()
.create(Api.class);
return api;
}
public interface Api {
@FormUrlEncoded
@POST("Countries/Get.php")
Single<CountryModelResponse> getCountries(@Field("id") int countryId);
}
}
CountriesRepository 類別
public class CountriesRepository {
public LiveData<Object> getCountries(Context context) {
MutableLiveData<Object> mutableLiveData = new MutableLiveData<>();
PublishSubject<String> retrySubject = PublishSubject.create();
RetrofitManager.getApi().getCountries(Navigation.findNavController(MainActivity.activityMainBinding.activityMainFragmentContainerViewContainer).getPreviousBackStackEntry() == null ? SharedPreferencesManager.getIntegerValue(context, SharedPreferencesManager.Keys.COUNTRY_ID.name()) : -1)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.doOnSubscribe(mutableLiveData::setValue)
.doOnError(throwable -> {
LinkedHashSet<Object> linkedHashSet = new LinkedHashSet<>();
linkedHashSet.add(!Utils.isInternetConnected(context) ? 100 : throwable instanceof SocketTimeoutException ? 200 : 300);
linkedHashSet.add(retrySubject);
mutableLiveData.setValue(linkedHashSet);
})
.retryWhen(throwableFlowable -> throwableFlowable.flatMap(throwable -> retrySubject.toFlowable(BackpressureStrategy.DROP).take(1), (throwable, s) -> s))
.subscribe(countryModelResponse -> {
if (countryModelResponse.getRequestStatus() == 100)
mutableLiveData.setValue(countryModelResponse);
else {
LinkedHashSet<Object> linkedHashSet = new LinkedHashSet<>();
linkedHashSet.add(300);
linkedHashSet.add(retrySubject);
mutableLiveData.setValue(linkedHashSet);
}
});
return mutableLiveData;
}
}
我不確定為什麼兩台伺服器之間會出現這種行為差異。
我正在使用最新版本的 PHP 和 WAMP 伺服器。
