在 PHP 中，$id 变量应该从客户端接收一个整数值。但是，当客户端使用POST请求方法将id值作为整数发送到PHP脚本时，当脚本上传到WAMP服务器时，它会自动转换为PHP中的字符串类型。另一方面，当脚本上传到Bluehost服务器上时，id值仍然是整数，不会转换为字符串，这正是我想要的。
这是一个简单的 PHP 脚本：
<?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.
从客户端发送的 id 值是通过 Android 应用程序发送的，这就是我将 id 值发送到 PHP 脚本的方式：
RetrofitManager 类
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 类
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;
}
}
我不确定为什么两台服务器之间会出现这种行为差异。
我正在使用最新版本的 PHP 和 WAMP 服务器。
