Question

我正在研究一个项目，该项目通过HTTPS POST请求将数据导入Web服务。为了创建HTTPS请求，我使用Retrofit2。这是我关于如何创建请求和评估响应的方法：

我正在创建一个存储信息的对象
我调用Object的方法，该方法将数据转换为适合请求的格式（JSON格式）
我创建了Retrofit Client并打电话。
最后一点是评估响应（此时，它会跳过onResponse（）方法，并使用JsonSyntaxException进入onFailure（）方法

我已经尝试过DateDeserializer ...很遗憾，没有任何结果

这是请求的格式：

tokenid=ABCDEFG
&bookuser=testuser
&input= {
    "0": {
        "ISSUEKEY": "ABC-81",
        "STARTDATE": "15.12.2016 09:00",
        "ENDDATE": "15.12.2016 11:30",
        "BOOKINGTEXT": "Testeintrag 1. Stephan Perner ISSUEKEY, ohne Sekunden"
    },
    "1": {
        "ISSUEKEY": "ABC-82",
        "STARTDATE": "15.12.2016 12:00",
        "ENDDATE": "15.12.2016 17:45",
        "BOOKINGTEXT": "Testeintrag 2. Stephan Perner, ohne Sekunden"
    }
}

这是当我按下按钮以开始发送过程时将调用的方法：


        w.setBookingtext("testeintrag#2");
        System.out.println("String: " + w.toRequest());
        String token = loadToken();
        Log.e(TAG, token);

        Call call = jiraService.postWorktime(token, "mschwar", "{\"0\":" + w.toRequest() + "}");

这是我为填充POST请求的正文而创建的改造库的调用：

    @POST("postWorktime")
    Call<PostWorkTimeResponse> postWorktime(@Field("tokenid") String token, @Field("bookuser") String bookuser, @Field("input") String input);

这是POJO：

import com.google.gson.annotations.SerializedName;

import org.json.JSONObject;

import java.sql.SQLOutput;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import java.util.TimeZone;

public class Worktime
{

    @SerializedName("ISSUEKEY")
    private String projectKey;
    @SerializedName("STARTDATE")
    private Date from;
    @SerializedName("ENDDATE")
    private Date to;
    @SerializedName("BOOKINGTEXT")
    private String bookingtext;

    public Worktime(Date from, Date to, String projectKey) {
        this.from = from;
        this.to = to;
        this.projectKey = projectKey;
    }

    public Date getFrom() {
        return from;
    }

    public void setFrom(Date from) {
        this.from = from;
    }

    public Date getTo() {
        return to;
    }

    public void setTo(Date to) {
        this.to = to;
    }

    public String getProjectKey() {
        return projectKey;
    }

    public void setProjectKey(String projectKey) {
        this.projectKey = projectKey;
    }

    public String getBookingtext() {
        return bookingtext;
    }

    public void setBookingtext(String bookingtext) {
        this.bookingtext = bookingtext;
    }

    @Override
    public String toString() {
        return "Worktime{" +
                "from=" + from +
                ", to=" + to +
                ", projectKey='" + projectKey + '\'' +
                ", bookingtext='" + bookingtext + '\'' +
                '}';
    }

    public String toRequest()
    {
        SimpleDateFormat df = new SimpleDateFormat("dd.MM.yyyy HH:mm", Locale.GERMANY);
        Date dStart = from;
        Date dEnd = to;
        dEnd.setHours(15);
        return String.format("{" +
                        "\"ISSUEKEY\":\"%s\"," +
                        "\"STARTDATE\":\"%s\"," +
                        "\"ENDDATE\":\"%s\"," +
                "\"BOOKINGTEXT\":\"%s\"" +
                               "}", projectKey, df.format(dStart), df.format(dEnd), bookingtext);
    }
}

这是我实现Callback接口的类：

package com.ssi.zeiterfassungsapp.webservice;

import android.content.Context;
import android.util.Log;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.reflect.TypeToken;
import com.ssi.zeiterfassungsapp.beans.PostWorkTimeRelated.PostWorkTimeResponse;
import com.ssi.zeiterfassungsapp.util.AsyncDelegate;

import java.lang.reflect.Type;

import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;

public class WorktimeImporter implements Callback
{
    private static final String TAG = "WorktimeImporter";
    private Context mContext;
    private AsyncDelegate delegate;
    private Gson gson;

    public WorktimeImporter(Context mContext, AsyncDelegate delegate) {
        this.mContext = mContext;
        this.delegate = delegate;
        gson = new GsonBuilder().setLenient().serializeNulls().setDateFormat("dd.MM.yyyy HH:mm").create();
    }

    @Override
    public void onResponse(Call call, Response response) {
        Type type = new TypeToken<PostWorkTimeResponse>(){}.getType(); //Creates instance of the Type (PostWorkTimeResponse)
        PostWorkTimeResponse workTimeResponse = null;
        Log.e(TAG, "Error in onResponse()");
        if(response.code() == 200){
            workTimeResponse = (PostWorkTimeResponse) response.body();

        }else
        {
            try {
                workTimeResponse = gson.fromJson(response.errorBody().string(), type); //Converts the response to LoginResponse
                Log.e(TAG, response.errorBody().string());
            } catch (Exception e) {
                Log.e(TAG, "Error: " + e.getMessage());
            }
        }
        Log.e(TAG, workTimeResponse.toString());
    }

    @Override
    public void onFailure(Call call, Throwable t) {
        t.printStackTrace();
    }
}

这是printStackTrace()的结果：

我希望有人可以帮助我解决这个问题，我对Retrofit和向Webservices发出请求相对较新。预先谢谢您，我将非常感谢您的帮助

请求的响应应如下所示：

{
"status": "Ok",
"token": "ABCDEFG",
"user": "testuser",
"origin": "XXX",
"target": "IF",
"bookuser": "testuser",
"booking": 
{
0: 
{
"ISSUEKEY": "ABC-81",
"STARTDATE": "15.12.2016 09:00",
"ENDDATE": "15.12.2016 11:30",
"BOOKINGTEXT": "Testeintrag 1. Stephan Perner auf korrekten ISSUEKEY, ohne Sekunden"
}
,
1: 
{
"ISSUEKEY": "ABC-82",
"STARTDATE": "15.12.2016 12:00",
"ENDDATE": "15.12.2016 17:45",
"BOOKINGTEXT": "Testeintrag 2. Stephan Perner auf korrekten ISSUEKEY, ohne Sekunden"
}
}
}

Answer 1

您可以像下面那样更新pojo

getFromAsDate()

您可以从getToAsDate()和{{1}}中获取对象的开始日期和结束日期

如何在日期转换时修复“ JsonSyntaxException”
