android - 改造2中的响应{协议(protocol)= http/1.1，代码= 404，消息=未找到，url = https://sub.domain.com}

Question

在iis 7中，我们成功地使用应用程序获取令牌，但是当我们将应用程序服务器从iis7升级到iis 8时，应用程序服务器返回以下错误…
响应{protocol=http/1.1，代码=404，消息=not found，url=https://sub.domain.com}
我们的改装2单吨级如下

public class RetrofitSingleton {

public static final String BASE_URL = "https://sub.domain.com";

private static Retrofit retrofit = null;
private static Context sContext;
private static Retrofit sRetrofit;

public RetrofitSingleton() {
}

public synchronized static Retrofit getInstance(Context context) {
    sContext=context;
    if(sRetrofit==null){
        createRetrofit();
    }
    return sRetrofit;
}

private static void createRetrofit(){

    TrustManagerFactory trustManagerFactory = null;
    try {
        trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    try {
        trustManagerFactory.init((KeyStore) null);
    } catch (KeyStoreException e) {
        e.printStackTrace();
    }
    TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
    if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
        throw new IllegalStateException("Unexpected default trust managers:" + Arrays.toString(trustManagers));
    }
    X509TrustManager trustManager = (X509TrustManager) trustManagers[0];
    SSLContext sslContext = null;
    try {
        sslContext = SSLContext.getInstance("SSL");
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    try {
        sslContext.init(null, new TrustManager[] { trustManager }, null);
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
    SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

    OkHttpClient okHttpClient= null;
    okHttpClient = new OkHttpClient.Builder()
            .sslSocketFactory(new TLSSocketFactory(),trustManager)
            .connectTimeout(2, TimeUnit.MINUTES)
            .readTimeout(2, TimeUnit.MINUTES)
            .writeTimeout(2, TimeUnit.MINUTES)
            //.sslSocketFactory(sslSocketFactory, trustManager)
            .followRedirects(false)
            .followSslRedirects(false)
            .retryOnConnectionFailure(false)
            .cache(null)//new Cache(sContext.getCacheDir(),10*1024*1024)
            .build();

    sRetrofit= new Retrofit.Builder()
            .client(okHttpClient)
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();
}

在我们的改装2 API接口之后

@FormUrlEncoded
@POST("/Api/Token")
Call<TokenInfo> getTokenAccess(@Field("grant_type") String grantType);

我们无法理解，由于将IIS 7升级到IIS 8，需要更改make anywhere的配置/代码。任何建议都非常感谢。
提前谢谢。
注：

 1. Using Postman we get token from our Asp.net Web api but from our android 
   app we cannot get token using retrofit 2.

 2. In IIS 7, our application & app works successfully.

你的改装单品课看起来不错。这可能不是您的IIS问题。对于ssl，iis 8比iis 7提供了更多的灵活性。在我的例子中，我遇到了iis 8的ssl配置不完整的问题。尝试使用正确的IIS SSL配置。遵循给定的链接：
