C# 请求第三方接口方式

方式1
curl
string postData = JsonConvert.SerializeObject(requestData);
// 定义curl命令及其参数
string curlPath = “curl”; // 假设curl命令在系统的PATH环境变量中

string path = “-X POST -H “Content-Type: application/json;charset=UTF-8” -H “Accept-Charset: UTF-8” -H “Accept-Encoding: gzip, deflate” -H “Accept-Language: zh-CN,zh;q=0.9” -d " + Regex.Replace(postData, @”“”|\", “\$&”) + " " + GlobalInfo.BaseUrl + “/weightCheck/submitSpc”; // curl的参数，即你想要执行的HTTP请求

// 创建ProcessStartInfo对象来配置进程启动信息
ProcessStartInfo startInfo = new ProcessStartInfo
{
FileName = curlPath, // 命令行程序的名称或路径
Arguments = path, // 传递给命令行程序的参数
UseShellExecute = false, // 是否使用操作系统shell启动进程
RedirectStandardOutput = true, // 是否将输出重定向到Process.StandardOutput流
CreateNoWindow = true // 不创建新窗口
};
string output;
// 启动进程并执行命令
using (Process process = new Process { StartInfo = startInfo })
{
process.Start();

// 使用 UTF-8 编码的 StreamReader 异步读取进程的标准输出  
using (StreamReader reader = new StreamReader(process.StandardOutput.BaseStream, Encoding.UTF8))
{
    output = await reader.ReadToEndAsync(); // 异步读取所有输出
    Console.WriteLine(output); // 打印输出到控制台  
}

await process.WaitForExitAsync(); // 异步等待进程完成
process.Close();

}
var json = JsonConvert.DeserializeObject(output);
if (json.code.Equals(20000) && json.data != null)
{
Growl.Success(new GrowlInfo() { Message = “提交成功!”, WaitTime = 1 });
return JsonConvert.DeserializeObject<List>(json.data.ToString());
}
else
{
throw new Exception($“请确认网络连接是否正常!! - 错误码: {json.code}”);
}
方式2
HttpClient
using (var httpClient = new HttpClient())
{
httpClient.Timeout = TimeSpan.FromSeconds(20);

 var content = new StringContent(postData, Encoding.UTF8, "application/json");

 using (var response = await httpClient.PostAsync(GlobalInfo.BaseUrl + "/weightCheck/submitSpc", content))
 {
     if (response.IsSuccessStatusCode)
     {
         string responseBody = await response.Content.ReadAsStringAsync();
         var json = JsonConvert.DeserializeObject<ResponseDto>(responseBody);

         if (json.code == 20000 && json.data != null)
         {
             XTrace.WriteLine($"提交成功!");
             return JsonConvert.DeserializeObject<List<SpcLimitDto>>(json.data.ToString());
         }
     }
     else
     {
         // Handle unsuccessful response
         Console.WriteLine($"HTTP request failed with status code {response.StatusCode}");
     }
 }

}
方式3
RestSharp
try
{
var client = new RestClient(GlobalInfo.BaseUrl);
var request = new RestRequest(“/weightCheck/submitSpc”, Method.Post);
request.AddHeader(“Content-Type”, “application/json”);
request.AddHeader(“Accept”, “application/json”);
request.AddParameter(“application/json”, postData, ParameterType.RequestBody);

 RestResponse response = client.Execute(request);
 var content = response.Content;

 if (response.StatusCode == HttpStatusCode.OK)
 {
     var json = JsonConvert.DeserializeObject<ResponseDto>(content);

     if (json.code.Equals(20000) && json.data != null)
     {
         Growl.Success(new GrowlInfo() { Message = "提交成功!", WaitTime = 1 });
         spcDataList = JsonConvert.DeserializeObject<List<SpcLimitDto>>(json.data.ToString());
         return spcDataList;
     }
     else
     {
         throw new Exception($"请确认网络连接是否正常!! - 错误码: {json.code}");
     }
 }
 else
 {
     throw new Exception($"请求失败: {response.StatusCode}");
 }

}
catch (Exception ex)
{
Growl.Error(new GrowlInfo() { Message = $“提交失败! -{ex.Message}”, WaitTime = 2 });
throw; // 抛出异常以供调用者处理
}
