Question

我正在构建一个Android应用程序，我通过Mashape市场使用Internet Game Database API。我正在使用Retrofit来获取请求，并且从API获取数据需要API密钥。

我让它工作，但API只返回游戏ID，我想要游戏名称和其他信息，但我不知道如何添加字段。这是Mashape查询它的方式：

private List<Product> GetProductList() {
  List<Product> products = new List<Product>();
  for (int i = 0; i < 14; i++) {
    products.Add(new Product(i.ToString(), "Model_" + i, "Manufacture_" + i, "Cat_" + i, "SubCat_" + i));
  }
  return products;
}

这是我的Retrofit Interface

System.Data.DataTable dt = new System.Data.DataTable();

public Form2() {
  InitializeComponent();
}

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) {
  //List<Product> list = ((DataParameter)e.Argument).ProductList;
  System.Data.DataTable list = ((DataParameter)e.Argument).ProductList;
  string filename = ((DataParameter)e.Argument).FileName;
  Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
  Workbook wb = excel.Workbooks.Add(XlSheetType.xlWorksheet);
  Worksheet ws = (Worksheet)excel.ActiveSheet;
  excel.Visible = false;
  int index = 1;
  //int process = list.Count;
  int process = list.Rows.Count;
  //Add Column
  ws.Cells[1, 1] = "Item Number";
  ws.Cells[1, 2] = "Model";
  ws.Cells[1, 3] = "Manufacturer";
  ws.Cells[1, 4] = "Category";
  ws.Cells[1, 5] = "Subcategory";
   foreach (DataRow dr in list.Rows) {
    if (!backgroundWorker.CancellationPending) {
      backgroundWorker.ReportProgress(index++ * 100 / process);
      ws.Cells[index, 1] = dr.ItemArray[1].ToString();
      ws.Cells[index, 2] = dr.ItemArray[2].ToString();
      ws.Cells[index, 3] = dr.ItemArray[3].ToString();
      ws.Cells[index, 4] = dr.ItemArray[4].ToString();
      ws.Cells[index, 5] = dr.ItemArray[5].ToString();
    }
  }
  //Save file
  ws.SaveAs(filename, XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);
  excel.Quit();
}

struct DataParameter {
  public System.Data.DataTable ProductList;
  public string FileName { get; set; }
}

DataParameter _inputParameter;

private void Form2_Load(object sender, EventArgs e) {
  string ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\Test\Test3.accdb";
  using (OleDbConnection olcon = new OleDbConnection(ConnectionString)) {
    using (OleDbDataAdapter adapter = new OleDbDataAdapter()) {

      string command = "SELECT * FROM [Products]";
      //cmd.CommandText = "SELECT * FROM [" + sheetName + "]";

      OleDbCommand cmd = new OleDbCommand(command, olcon);
      //Fill Gridview with Data from Access
      try {
        dt.Clear();
        adapter.SelectCommand = cmd;
        adapter.Fill(dt);
        productBindingSource.DataSource = dt;
        dataGridView1.DataSource = productBindingSource;
      }
      catch (Exception ex) {
        MessageBox.Show(ex.ToString());
      }
      finally {
        olcon.Close();
        var totalWidth = dataGridView1.Columns.GetColumnsWidth(DataGridViewElementStates.None);
      }
    }
  }

}

 private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) {
  progressBar.Value = e.ProgressPercentage;
  lblStatus.Text = string.Format("Processing...{0}", e.ProgressPercentage);
  progressBar.Update();
}

private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) {
  if (e.Error == null) {
    Thread.Sleep(100);
    lblStatus.Text = "Your data has been successfully exported.";
  }
}

private void btnExport_Click(object sender, EventArgs e) {
  if (backgroundWorker.IsBusy)
    return;
  using (SaveFileDialog sfd = new SaveFileDialog() { Filter = "Excel Workbook|*.xls" }) {
    if (sfd.ShowDialog() == DialogResult.OK) {
      _inputParameter.FileName = sfd.FileName;
      //_inputParameter.ProductList = GetProductsList2();
      _inputParameter.ProductList = (System.Data.DataTable)productBindingSource.DataSource;
      progressBar.Minimum = 0;
      progressBar.Value = 0;
      backgroundWorker.RunWorkerAsync(_inputParameter);
    }
  }
}

我试着用这个

    HttpResponse<String> response = Unirest.get("https://igdbcom-internet-game-database-v1.p.mashape.com/games/?fields=name%2Crelease_dates")
.header("X-Mashape-Key", "API KEY HERE")
.header("Accept", "application/json")
.asString();

但没有运气，我也试过@Field，但也没用。有任何想法吗？谢谢。

编辑：只是为了澄清我添加public interface GamesAPIService { @GET("/games/") Call<List<GamesResponse>> gameList(@Query("mashape-key") String apikey); }的时间，我收到401 Unauthorized Error。

首先，我认为您需要为所有请求添加mashape密钥。

OkHttpClient httpClient = new OkHttpClient();
httpClient.addInterceptor(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request().newBuilder()
            .addHeader("X-Mashape-Key", "API_KEY_HERE")
            .addHeader("Accept", "application/json")
            .build();
        return chain.proceed(request);
    }
});
Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://igdbcom-internet-game-database-v1.p.mashape.com")
    .client(httpClient)
    .build();

然后这是信息查询。

public interface GamesAPIService {
    @GET("/games")
    Call<List<GamesResponse>> gameList(@Query("fields") String value);
}

最后一次打电话。

GamesAPIService gamesAPIService = retrofit.create(GamesAPIService.class);

Call<List<GamesResponse>> call = gamesAPIService.gameList("name,release_dates");
if (call!=null){
    call.enqueue(new Callback<List<GamesResponse>>() {

        @Override
        public void onResponse(Call<List<GamesResponse>> call, Response<List<GamesResponse>> response) {
            // handle success
        }

        @Override
        public void onFailure(Throwable t) {
            // handle failure
        }
   });
}

使用Retrofit将字段添加到URL
