static async Task Main(string[] args)
{
using (HttpClient client = new HttpClient())
{
// 设置请求的URL
string url = "https://example.com/api/resource";
// 创建要发送的数据
var content = new StringContent(
"{\"key1\":\"value1\", \"key2\":\"value2\"}",
Encoding.UTF8,
"application/json"
);
try
{
// 发送POST请求并获取响应
HttpResponseMessage response = await client.PostAsync(url, content);
// 确保请求成功
response.EnsureSuccessStatusCode();
// 读取响应内容
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
catch (HttpRequestException e)
{
Console.WriteLine($"Request error: {e.Message}");
}
}
}
}
这个示例展示了如何使用C#发送一个POST请求,并处理响应。
