c#httpclient中get、 POST、PUT、DELETE、HEAD、OPTIONS、TRACE方法代码实现
1. GET方法
```csharp
using System.Net.Http;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 发送GET请求
HttpResponseMessage response = await client.GetAsync("http://www.example.com");
string responseBody = await response.Content.ReadAsStringAsync();
```
2. POST方法
```csharp
using System.Net.Http;
using System.Text;
using System.Text.Json;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 准备POST请求数据
var data = new { name = "John", age = 30 };
var jsonContent = JsonSerializer.Serialize(data);
var content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
// 发送POST请求
HttpResponseMessage response = await client.PostAsync("http://www.example.com", content);
string responseBody = await response.Content.ReadAsStringAsync();
```
3. PUT方法
```csharp
using System.Net.Http;
using System.Text;
using System.Text.Json;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 准备PUT请求数据
var data = new { name = "John", age = 30 };
var jsonContent = JsonSerializer.Serialize(data);
var content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
// 发送PUT请求
HttpResponseMessage response = await client.PutAsync("http://www.example.com", content);
string responseBody = await response.Content.ReadAsStringAsync();
```
4. DELETE方法
```csharp
using System.Net.Http;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 发送DELETE请求
HttpResponseMessage response = await client.DeleteAsync("http://www.example.com");
string responseBody = await response.Content.ReadAsStringAsync();
```
5. HEAD方法
```csharp
using System.Net.Http;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 发送HEAD请求
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Head, "http://www.example.com");
HttpResponseMessage response = await client.SendAsync(request);
```
6. OPTIONS方法
```csharp
using System.Net.Http;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 发送OPTIONS请求
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Options, "http://www.example.com");
HttpResponseMessage response = await client.SendAsync(request);
```
7. TRACE方法
```csharp
using System.Net.Http;
// 创建HttpClient对象
HttpClient client = new HttpClient();
// 发送TRACE请求
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Trace, "http://www.example.com");
HttpResponseMessage response = await client.SendAsync(request);
```
JAVA和C#调用CSB服务示例
这里提供一个简单的JAVA调用CSB服务的示例代码:
```java
import com.alibaba.csb.sdk.*;
import com.alibaba.fastjson.JSON;
import java.util.HashMap;
import java.util.Map;
public class TestCSBJAVA {
public static void main(String[] args) throws Exception {
String ak = "your access key";
String sk = "your secret key";
String endpoint = "your endpoint";
String api = "your api path";
String version = "your api version";
String protocol = "http";
Map<String, Object> params = new HashMap<String, Object>();
params.put("name", "test");
params.put("age", 20);
// 构建请求对象
Request request = new Request();
request.setAk(ak);
request.setSk(sk);
request.setEndpoint(endpoint);
request.setApi(api);
request.setVersion(version);
request.setProtocol(protocol);
request.setMethod(MethodType.POST);
request.setRequestData(JSON.toJSONString(params)); // 转换成JSON格式
// 发送请求
Response response = HttpCaller.invoke(request);
// 解析响应结果
if (response.isSuccess()) {
String result = response.getResponseData();
System.out.println(result);
} else {
System.out.println(response.getMessage());
}
}
}
```
这里提供一个简单的C#调用CSB服务的示例代码:
```csharp
using Com.Alibaba.Csb.Sdk;
using Newtonsoft.Json;
using System.Collections.Generic;
public class TestCSBCSharp
{
public static void Main(string[] args)
{
string ak = "your access key";
string sk = "your secret key";
string endpoint = "your endpoint";
string api = "your api path";
string version = "your api version";
string protocol = "http";
Dictionary<string, object> parameters = new Dictionary<string, object>();
parameters.Add("name", "test");
parameters.Add("age", 20);
// 构建请求对象
Request request = new Request();
request.Ak = ak;
request.Sk = sk;
request.Endpoint = endpoint;
request.Api = api;
request.Version = version;
request.Protocol = protocol;
request.Method = MethodType.POST;
request.RequestData = JsonConvert.SerializeObject(parameters);
// 发送请求
Response response = HttpCaller.Invoke(request);
// 解析响应结果
if (response.IsSuccess())
{
string result = response.GetResponseData();
Console.WriteLine(result);
}
else
{
Console.WriteLine(response.GetMessage());
}
}
}
```
以上示例代码仅供参考,具体实现需要根据自己的需求进行调整。
