经过一段时间的工作和使用，因为开发的客户端要跟服务器中提供的Web API进行频繁的数据交换，所有将与API调用的部分抽象出了几个方法，今天跟大家一起方法，当然方法不限于此，只是为大家做一个引导。 1、通过GET方式有参获取对象
/// <summary>
/// 通过GET方式获取对象
/// </summary>
/// <typeparam name="TInput">输入类型</typeparam>
/// <typeparam name="TOutput">输出类型</typeparam>
/// <param name="url">请求地址</param>
/// <param name="msg">提示消息</param>
/// <param name="prm">参数</param>
/// <param name="hasProcessDialog">是否需要Loading</param>
/// <param name="activity">窗体</param>
/// <returns></returns>
public static async Task<TOutput> GetObjectByGet<TInput, TOutput>(string url, string msg, TInput prm, bool hasProcessDialog, Activity activity) where TOutput : class
{
var dialog = new ProgressDialogHelper();
if (hasProcessDialog)
{
dialog.ShowProgressDialog(activity, ProgressDialogStyle.Spinner, msg);
}
var urlNew = url + "?" + QuerystringConvert.ConvertFromObject(prm);
var client = new HttpClient();
try
{
var httpResponse = await client.GetAsync(urlNew);
var result = httpResponse.Content;
var txtStream = await result.ReadAsStreamAsync();
if (hasProcessDialog)
{
dialog.CloseProgressDialog();
}
return JsonConvert.DeserializingObject<TOutput>(txtStream);
}
catch (Exception ex)
{
if (hasProcessDialog)
{
dialog.CloseProgressDialog();
}
return null;
}
}2、通过GET方法无参获取对象
/// <summary>
/// 通过GET方法无参数获取对象
/// </summary>
/// <typeparam name="TOutput">输出类型</typeparam>
/// <param name="url">请求地址</param>
/// <param name="msg">提示消息</param>
/// <param name="hasProcessDialog">是否需要Loading</param>
/// <param name="activity">窗体</param>
/// <returns></returns>
public static async Task<TOutput> GetObjectByGetWithNoParameter<TOutput>(string url, string msg, bool hasProcessDialog, Activity activity) where TOutput : class
{
var dialog = new ProgressDialogHelper();
if (hasProcessDialog)
{
dialog.ShowProgressDialog(activity, ProgressDialogStyle.Spinner, msg);
}
var client = new HttpClient();
try
{
var httpResponse = await client.GetAsync(url);
var result = httpResponse.Content;
var txtStream = await result.ReadAsStreamAsync();
if (hasProcessDialog)
{
dialog.CloseProgressDialog();
}
return JsonConvert.DeserializingObject<TOutput>(txtStream);
}
catch (Exception ex)
{
if (hasProcessDialog)
{
dialog.CloseProgressDialog();
}
return null;
}
}3、通过POST方式有参获取对象
/// <summary>
/// 通过POST方式获取对象
/// </summary>
/// <typeparam name="TInput">输入类型</typeparam>
/// <typeparam name="TOutput">输出类型</typeparam>
/// <param name="url">请求地址</param>
/// <param name="msg">提示消息</param>
/// <param name="prm">参数</param>
/// <param name="hasProcessDialog">是否需要Loading</param>
/// <param name="activity">窗体</param>
/// <returns></returns>
public static async Task<TOutput> GetObjectByPost<TInput, TOutput>(string url, string msg, TInput prm, bool hasProcessDialog, Activity activity) where TOutput : class
{
var dialog = new ProgressDialogHelper();
if (hasProcessDialog)
{
dialog.ShowProgressDialog(activity, ProgressDialogStyle.Spinner, msg);
}
var client = new HttpClient();
try
{
var jsonString = JsonConvert.SerializeObject(prm);
if (jsonString == null)
{
return null;
}
var httpResponse = await client.PostAsync(url, new StringContent(jsonString, Encoding.UTF8, "application/json"));
var result = httpResponse.Content;
var txtStream = await result.ReadAsStreamAsync();
if (hasProcessDialog)
{
dialog.CloseProgressDialog();
}
return JsonConvert.DeserializingObject<TOutput>(txtStream);
}
catch (Exception ex)
{
if (hasProcessDialog)
{
dialog.CloseProgressDialog();
}
return null;
}
}4、通过GET方式获取字符串
/// <summary>
/// 通过GET方式获取字符串
/// </summary>
/// <typeparam name="TInput">输入类型</typeparam>
/// <param name="url">请求地址</param>
/// <param name="msg">提示信息</param>
/// <param name="prm">参数</param>
/// <param name="activity">窗体</param>
/// <returns></returns>
public static async Task<string> GetStringByGet<TInput>(string url, string msg, TInput prm, Activity activity)
{
var dialog = new ProgressDialogHelper();
dialog.ShowProgressDialog(activity, ProgressDialogStyle.Spinner, msg);
var urlNew = url + QuerystringConvert.ConvertFromObject(prm);
var client = new HttpClient();
try
{
var httpResponse = await client.GetAsync(urlNew);
var result = httpResponse.Content;
dialog.CloseProgressDialog();
var txt = await result.ReadAsStringAsync();
return txt;
}
catch (Exception ex)
{
dialog.CloseProgressDialog();
return null;
}
}5、通过POST方式取字符串
/// <summary>
/// 通过POST方式取字符串
/// </summary>
/// <typeparam name="TInput">输入类型</typeparam>
/// <param name="url">请求地址</param>
/// <param name="msg">提示信息</param>
/// <param name="prm">参数</param>
/// <param name="activity">窗体</param>
/// <returns></returns>
public static async Task<string> GetStringByPost<TInput>(string url, string msg, TInput prm, Activity activity)
{
var dialog = new ProgressDialogHelper();
dialog.ShowProgressDialog(activity, ProgressDialogStyle.Spinner, msg);
var client = new HttpClient();
try
{
var jsonString = JsonConvert.SerializeObject(prm);
if (jsonString == null)
{
return null;
}
var httpResponse = await client.PostAsync(url, new StringContent(jsonString, System.Text.Encoding.UTF8, "application/json"));
var result = httpResponse.Content;
dialog.CloseProgressDialog();
var txt = await result.ReadAsStringAsync();
return txt;
}
catch (Exception ex)
{
dialog.CloseProgressDialog();
return null;
}
}
