在改造 2.0 中总是进入 onFailure

Question

我正在尝试访问 api：www.xyz.com/abc_cc/cc/userregister/newuser

这是我的代码：

    public class MainActivity extends AppCompatActivity {


    public static final String BASE_URL = "abc.com/abc_cc/cc/";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
.client(getUnsafeOkHttpClient())
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        Endpoints endpoints= retrofit.create(Endpoints.class);
        endpoints.newuser("{\"full_name\":\"sss\",\"states_id\":\"20\",\"mobile\":\"9876543210\",\"password\":\"******\",\"accept_terms\":true,\"Userid\":\"0\",\"refer\":\"\",\"ip-address\":\"1.2.3.4\",\"device_type\":\"samsung J5\",\"os-version\":\"5.0.1\",\"client\":\"app\",\"secret_key\":\"44\"}")
                .enqueue(new retrofit2.Callback<Items>() {
                    @Override
                    public void onResponse(retrofit2.Call<Items> call, retrofit2.Response<Items> response) {
                        System.out.println("onResponse : "+response.message());
                        System.out.println("onResponse : "+response.body());
                        System.out.println("onResponse : "+response.code());
                        System.out.println("onResponse : "+response.errorBody());
                        System.out.println("onResponse : "+response.isSuccessful());
                        System.out.println("onResponse : "+response.raw());
                        System.out.println("onResponse : "+response);
                    }

                    @Override
                    public void onFailure(retrofit2.Call<Items> call, Throwable t) {
                        System.out.println("onFailure"+call);

                    }
                });


    }

    public static OkHttpClient getUnsafeOkHttpClient() {

        try {
            // Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
                @Override
                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] chain,
                        String authType) throws CertificateException {
                }

                @Override
                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] chain,
                        String authType) throws CertificateException {
                }

                @Override
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new java.security.cert.X509Certificate[0];
                }
            } };

            // Install the all-trusting trust manager
            final SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, trustAllCerts,
                    new java.security.SecureRandom());
            // Create an ssl socket factory with our all-trusting manager
            final SSLSocketFactory sslSocketFactory = sslContext
                    .getSocketFactory();

            OkHttpClient okHttpClient = new OkHttpClient();
            okHttpClient = okHttpClient.newBuilder()
                    .sslSocketFactory(sslSocketFactory)
                    .hostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER).build();

            return okHttpClient;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }

    }

}

界面：

public interface Endpoints {
    @POST("/userregister/newuser")
    @FormUrlEncoded
    Call<Items> newuser(@Field("Data") String Data);

}

POJO 类：

public class Items {
    @SerializedName("Response-Status")
    @Expose
    private Boolean responseStatus;
    @SerializedName("Response-Validate")
    @Expose
    private Boolean responseValidate;
    @SerializedName("Response-Message")
    @Expose
    private String responseMessage;
    @SerializedName("Response-Data")
    @Expose
    private ResponseData responseData;

    public Boolean getResponseStatus() {
        return responseStatus;
    }

    public void setResponseStatus(Boolean responseStatus) {
        this.responseStatus = responseStatus;
    }

    public Boolean getResponseValidate() {
        return responseValidate;
    }

    public void setResponseValidate(Boolean responseValidate) {
        this.responseValidate = responseValidate;
    }

    public String getResponseMessage() {
        return responseMessage;
    }

    public void setResponseMessage(String responseMessage) {
        this.responseMessage = responseMessage;
    }

    public ResponseData getResponseData() {
        return responseData;
    }

    public void setResponseData(ResponseData responseData) {
        this.responseData = responseData;
    }

}

我收到了这样的回复：

{protocol=http/1.1, code=404, message=Not Found, url=www.xyz.com/userregister/newuser}

我已经给出了正确的网址，为什么它只占用了一半？

我已经尝试了https://code.tutsplus.com/tutorials/sending-data-with-retrofit-2-http-client-for-android--cms-27845 中的示例。此示例和示例中给出的链接工作正常，但如果我对我的 url 执行相同操作，则会收到上述错误

Answer 1

我希望请检查您的解析问题可能发生。

 @Override
public void onFailure(retrofit2.Call<Items> call, Throwable t) {
 System.out.println("onFailure"+call);

//添加这个lije你有例外。

 t.printStackTrace();
 }

Answer 2

请参阅docs for Retrofit.Builder 以获得更详细的说明，但要特别注意这些位：

基本 URL 应始终以 / 结尾。

尾随 / 确保端点值是相对路径 将正确地将自己附加到具有路径组件的基础。

...

包含前导 / 的端点值是绝对值。

绝对值仅保留来自 baseUrl 的主机并忽略任何 指定路径组件。

正如目前所写，在您对 Endpoints.newuser() 的调用中引用的路径是绝对路径，因此您的基本 URL 中的主机之后的路径段将被删除（因为这是记录在案的行为）。

因此，您应该更改您的Endpoints 接口以使用相对路径，如下所示：

    public interface Endpoints {
        @POST("userregister/newuser")
        @FormUrlEncoded
        Call<Items> newuser(@Field("Data") String Data);
    }

Answer 3

为此更改您的Endpoints 界面：

public interface Endpoints {
    @POST("userregister/newuser")
    @FormUrlEncoded
    Call<Items> newuser(@Field("Data") String Data);

}

请注意，我删除了尾部斜杠 /。这样，Retrofit 会将您定义的路径附加到 BASE_URL。
