Question

（编辑我添加了一个小型演示测试）

我是Retrofit的新手。我需要做的是从服务器检索XML文件并将其转换为POJO。问题是我的测试服务器上的所有内容都与静态文件完美配合，但是当我在真实服务器上尝试此操作时，我无法使其与Retrofit2一起使用，但是当我直接使用时它确实有效使用OkHttp，因此我猜测生成的Request出了问题。

编辑：我将代码切换为使用字符串转换器，因为问题仅在于响应。

这是我的基本实现。

public interface ZedoClient {
@retrofit2.http.Headers({
        "User-Agent: Mozilla/5.0 (Linux; Android 5.1; Quattro_L50_HD LMY47D/Quattro_L50_HD)",
        "Cookie : ZCBC=1;FFcat=3533,3,90;FFad=0;FFMChanCap=5345280B3533,3#2605191|0,1#0,24:"
})
@GET("fns.vast")
Call<Vast> getVast(@QueryMap(encoded=true) Map<String, String> options);

我添加了两个Interceptor以设置headers和cookies： AddCookiesInterceptor.class

class AddCookiesInterceptor implements Interceptor {
    private final Headers headers;

    AddCookiesInterceptor(Headers headers) {
        this.headers = headers;
    }
    @Override
    public okhttp3.Response intercept(Chain chain) throws IOException {
        Request.Builder builder = chain.request().newBuilder();
        builder.headers(headers);
        return chain.proceed(builder.build());
    }
}

ReceivedCookiesInterceptor.class

class ReceivedCookiesInterceptor implements Interceptor {
    @Override
    public okhttp3.Response intercept(Chain chain) throws IOException {
        okhttp3.Response originalResponse = chain.proceed(chain.request());

        if (!originalResponse.headers("Set-Cookie").isEmpty()) {
            HashSet<String> cookies = new HashSet<>();
            for (String header : originalResponse.headers("Set-Cookie")) {
                cookies.add(header);
            }
        }
        return originalResponse;
    }
}

以下是我所做的测试，它显示了原始OkHttp如何按预期工作，但retrofit2失败了：

public static Vast test(String baseUrl, Map<String, String> queryParams, final Headers headers) {
    try {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient httpClient = new OkHttpClient.Builder().addInterceptor(logging).build();
        Request.Builder request = new Request.Builder()
                .url("http://********/fns.vast?v=vast2&d=90&ct=mnf%3AKARBONN%5Emdn%3AQuattro_L50_HD%5Emdu%3AQuattro_L50_HD%5Etyp%3ASmartPhone%5Econ%3Awifi%5Eosn%3AAndroid%5Evsn%3A5.1%5Eosv%3A22%5Ecn%3AUS%5Elng%3Aen%5E&s=3&n=3533&c=3&z=0.4933822377892413");
        if (headers != null) {
            request.headers(headers);
        }
        okhttp3.Response oldRespnse = httpClient.newCall(request.build()).execute();
        System.out.println("successsForOkhttp: " + oldResponse.isSuccessful());
        OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
        if (headers != null) {
            clientBuilder.networkInterceptors().add(logging);
            clientBuilder.networkInterceptors().add(new AddCookiesInterceptor(headers));
            clientBuilder.networkInterceptors().add(new ReceivedCookiesInterceptor());
        }
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .client(clientBuilder.build())
                .addConverterFactory(SimpleXmlConverterFactory.create())
                .build();

        ZedoClient client = retrofit.create(ZedoClient.class);
        Call<Vast> call = client.getVast(queryParams);
        Response<Vast> response = call.execute();
        System.out.println("successsForRetrofit: " + response.isSuccessful());
        if (response.isSuccessful()) {
            return response.body();
        } else {
            MyLog.e("error:" + response.raw().message());
            return null;
        }
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }

}

这是输出：

I/System.out: successsForOkhttp: true
I/System.out: successsForRetrofit: false
I/System.out: error:Bad Request

根据建议，我为Logging-Interceptor请求和OkHttp请求添加了Retrofit2，这是输出：

Althogth两个调用都使用相同的GET，Retrofit2调用失败了400.可能是Headers或Cookie，但我无法解决。

Answer 1

我认为最好在OkHttp中启用日志记录并检查

请求的网址是正确的
收到的数据也是正确的。

有关如何启用OkHttp Loggin的更多信息，请访问：https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor

在OkHttp工作正常的情况下，Retrofit2响应是错误的请求
