使用 Retrofit 消耗剩余 api

Consuming rest api using Retrofit

我正在研究 android studio。我正在尝试消费 Rest API。现在我正在使用 Postman 来完成我的工作。

Body部分

Header部分

回应

{
"data": [
    {
        "global_device_id": "982010",
        "msn": "002998002010",
        "relay_operate": "1"
    }
],
"message": "Auxiliary Relay Status",
"transactionid": "Abdfqwe332432423ti", 
"status": "1"
} 

我做了什么?

@POST("UIP/on_demand_parameter_read")
Call<UIPResponse> getRelayResponse(@Header("transactionid") String tid, @Header("privatekey") String pk, @Header("Content-Type") String ct,
                              @Body OnDemand onDemand);

按需class

public class OnDemand {

@SerializedName("global_device_id")
@Expose
private String global_device_id;
@SerializedName("type")
@Expose
private String type;



public String getGlobal_device_id() {
    return global_device_id;
}

public void setGlobal_device_id(String global_device_id) {
    this.global_device_id = global_device_id;
}


public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}


public OnDemand(String global_device_id, String type) {
    this.global_device_id = global_device_id;
    this.type = type;
}
}

UIP 响应 Class

package com.thumbsol.accuratemobileassetsmanagament.model;



import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

import java.util.List;


public class UIPResponse
{
@SerializedName("data")
@Expose
private List<Datum> data = null;
@SerializedName("message")
@Expose
private String message;
@SerializedName("transactionid")
@Expose
private String transactionid;
@SerializedName("status")
@Expose
private String status;

public List<Datum> getData() {
    return data;
}

public void setData(List<Datum> data) {
    this.data = data;
}

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

public String getTransactionid() {
    return transactionid;
}

public void setTransactionid(String transactionid) {
    this.transactionid = transactionid;
}

public String getStatus() {
    return status;
}

public void setStatus(String status) {
    this.status = status;
}

}

class Datum {

@SerializedName("global_device_id")
@Expose
private String globalDeviceId;
@SerializedName("msn")
@Expose
private String msn;
@SerializedName("relay_operate")
@Expose
private String relayOperate;

public String getGlobalDeviceId() {
    return globalDeviceId;
}

public void setGlobalDeviceId(String globalDeviceId) {
    this.globalDeviceId = globalDeviceId;
}

public String getMsn() {
    return msn;
}

public void setMsn(String msn) {
    this.msn = msn;
}

public String getRelayOperate() {
    return relayOperate;
}

public void setRelayOperate(String relayOperate) {
    this.relayOperate = relayOperate;
}

}

改装Class

public static Retrofit getOnDemandRequest() {
    if (retrofitSignalStrength == null) {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(logging)
                .connectTimeout(1000, TimeUnit.SECONDS)
                .readTimeout(1000,TimeUnit.SECONDS)
                .build();
        retrofitSignalStrength = new
                Retrofit.Builder().baseUrl(BASE_URL_STAT)
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();
    }
    return retrofitSignalStrength;
}

然后终于在我的按钮中onClick我完成了

 OnDemand onDemand = new OnDemand(global_device_id, type);

            Retrofit retrofit = RetrofitClient.getOnDemandRequest();
            RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);
            Call<UIPResponse> call = retrofitInterface.getRelayResponse(transactionid, privatekey, content_type, onDemand);

            call.enqueue(new retrofit2.Callback<UIPResponse>() {
                @Override
                public void onResponse(Call<UIPResponse> call, Response<UIPResponse> response) {

                    boolean isSuccess = false;

                    if(response.isSuccessful())
                    {

                    }


                }

                @Override
                public void onFailure(Call<UIPResponse> call, Throwable t) {

                }
            });

调试

调试时,我的速度低于日志

我一定是漏掉了一些我不知道的东西

非常感谢任何帮助。

访问 REST API 在 Android 开发人员指南中给出。尝试此处给出的示例:https://developers.google.com/android/guides/http-auth

如果没有,请在清单中添加 Internet 权限。你可以查一下https://developer.android.com/training/basics/network-ops/connecting

您尝试过使用其他 api 吗?如果没有,请先尝试。只需在 google 中找到一些 Dummy API。这是给你的例子 https://reqres.in/

我记得 okttp 要求安全 api。我可以看到你没有使用它。请参考此 link https://developer.android.com/training/articles/security-config 信任所有连接。您需要将其添加到清单中,但请先阅读。祝你好运

您是否像此处描​​述的那样初始化了库? https://amitshekhar.me/Fast-Android-Networking/adding_fan_to_your_project.html

如果它正在执行调用,您还可以启用日志记录并签入 logcat:

https://amitshekhar.me/Fast-Android-Networking/logging.html

使用@FormUrlEncoded

@Headers("Content-Type: application/x-www-form-urlencoded")
@FormUrlEncoded
@POST("UIP/on_demand_parameter_read")
Call<UIPResponse> getRelayResponse(
    @Header("transactionid") String tid, 
    @Header("privatekey") String pk,
    @Field("global_device_id") String deviceId,  
    @Field("type") String type
);
