我正在尝试通过skyscanner api访问票证数据并将其传递到我的视图，但是我无法实现这一点，因为我收到415错误代码，我正在使用Retrofit2并以编程方式添加标头。 我的界面如下所示：

public interface GetFlightDetails {

@POST("apiservices/pricing/v1.0/")

Call getFlightList(@Query("apiKey") String apiKey,

@Query("country") String country,

@Query("currency") String currency,

@Query("locale") String locale,

@Query("originPlace") String originPlace,

@Query("destinationPlace") String destinationPlace,

@Query("outboundPartialDate")String outboundPartialDate,

@Query("inboundPartialDate") String inboundPartialDate,

@Query("locationschema") String locationschema,

@Query("cabinclass") String cabinclass,

@Query("adults") int adults,

@Query("children") int children,

@Query("infants") int infants,

@Query("groupPricing") boolean groupPricing) ;

}

在我的活动中，当我准备提出请求时，我具有以下代码：

Gson gson = new GsonBuilder()

.setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ")

.create();

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

//adding logging

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();

logging.setLevel(HttpLoggingInterceptor.Level.BASIC);

httpClient.interceptors().add(logging);

//headers

httpClient.addInterceptor(new Interceptor() {

@Override

public okhttp3.Response intercept(Chain chain) throws IOException {

Request original = chain.request();

//adding header info

Request request = original.newBuilder()

.header("Content-Type", "application/x-www-form-urlencoded")

.header("Accept", "application/json")

.method(original.method(), original.body())

.build();

return chain.proceed(request);

}

});

Retrofit retrofit = new Retrofit.Builder()

.baseUrl(BASE_URL)

.addConverterFactory(GsonConverterFactory.create(gson))

.client(httpClient.build())

.build();

GetFlightDetails api = retrofit.create(GetFlightDetails.class);

Call mresponse = api

.getFlightList(API_KEY, country, currency, locale, from, to,

departDate.substring(0,10), returnDate.substring(0,10),

locationSchema, cabinClass, adult, children, infants, false);

mresponse.enqueue(new Callback()

{

@Override

public void onResponse(Call call, Response response) {

if (!response.isSuccessful()){

Log.d("UnSuccess", response.raw().toString());

return;

}

else {

progress.cancel(); //cancel progress dialog

Log.d("Success", response.raw().toString());

TicketData ticketData = response.body();

RecyclerAdapter adapter = new RecyclerAdapter(getApplicationContext(), ticketData);

mRecyclerView.setAdapter(adapter);

}

}

@Override

public void onFailure(Call call, Throwable t){

progress.setMessage("Retrofit Error Occured");

}

});

在我的日志文件中，看到以下错误：

com.example.ex D/OkHttp: --> POST http://partners.api.skyscanner.net/apiservices/pricing/v1.0/?apiKey=xxxxxxxx&country=US&currency=USD&locale=en-us&originPlace=SFO&destinationPlace=LAX&outboundPartialDate=2016-10-24&inboundPartialDate=2016-10-31&locationschema=iata&cabinclass=Economy&adults=1&children=0&infants=0&groupPricing=false http/1.1 (0-byte body)

com.example.ex D/OkHttp:

我不确定为什么会这样，因为我尝试在界面中添加标头。

Skyscanner文档参考1和参考2

谢谢！
