请帮忙 CloseableHttpClient请求用这个格式Content-Type:application/json

可以使用 HttpEntity 来设置 Content-Type 为 application/json。代码示例:
```
StringEntity entity = new StringEntity(jsonString);
entity.setContentType("application/json");
HttpPost request = new HttpPost(url);
request.setEntity(entity);
CloseableHttpResponse response = httpClient.execute(request);
```
其中 jsonString 为 json 格式的请求体。

java如何接受curl -H "Content-Type: application/json" -X POST -d '{"user_id": "123", "coin":100, "success":1, "msg":"OK!" }'中-d中的POST内容
在Java中,可以使用Apache HttpClient库来发送HTTP请求,并接收cURL命令中-d参数的POST内容。以下是示例代码:
```java
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
public class CurlToJava {
public static void main(String[] args) {
CloseableHttpClient httpClient = HttpClients.createDefault();
try {
HttpPost httpPost = new HttpPost("http://example.com/api/endpoint");
// 设置请求头
httpPost.setHeader("Content-Type", "application/json");
// 设置请求体
String jsonBody = "{\"user_id\": \"123\", \"coin\":100, \"success\":1, \"msg\":\"OK!\" }";
StringEntity entity = new StringEntity(jsonBody);
httpPost.setEntity(entity);
// 发送请求
HttpResponse response = httpClient.execute(httpPost);
// 获取响应内容
HttpEntity responseEntity = response.getEntity();
String responseBody = EntityUtils.toString(responseEntity);
System.out.println(responseBody);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
httpClient.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
```
在上述代码中,我们创建了一个HttpPost对象,并设置了请求URL、请求头和请求体。通过执行`httpClient.execute(httpPost)`方法发送请求并获取响应。最后,我们将响应内容转换为字符串并进行处理。
header.accountId = 12345678, header.serviceName CreateOrder, header.version 1.0, header.sign = 4F 72 64 65 72 42 6F 64 , body = rO0ABXNyABZqYXZhLnV0aWwuTGlzdGluZ0wzNDPartaL。 接口URL:POST http://localhost:9010/mini/index Content-Type:application/json 认证方式:无需认证 请求参数= { "header" : { "accountId" : "", "serviceName" : "", "version" : "1.0", "sign" : "" }, "body" : "" } Java怎么调用这个URL接口
可以使用Java的HttpClient库来调用这个URL接口。具体步骤如下:
1. 创建HttpClient对象:
```
CloseableHttpClient httpclient = HttpClients.createDefault();
```
2. 创建HttpPost对象,并设置URL和请求体:
```
HttpPost httpPost = new HttpPost("http://localhost:9010/mini/index");
StringEntity entity = new StringEntity("{\"header\":{\"accountId\":\"12345678\",\"serviceName\":\"CreateOrder\",\"version\":\"1.0\",\"sign\":\"4F 72 64 65 72 42 6F 64\"},\"body\":\"rO0ABXNyABZqYXZhLnV0aWwuTGlzdGluZ0wzNDPartaL\"}", ContentType.APPLICATION_JSON);
httpPost.setEntity(entity);
```
3. 发送请求并获取响应:
```
CloseableHttpResponse response = httpclient.execute(httpPost);
HttpEntity responseEntity = response.getEntity();
String responseStr = EntityUtils.toString(responseEntity, "UTF-8");
```
其中,responseStr即为接口返回的响应内容。需要注意的是,该接口请求中的信息可能已经过时或被修改,使用时请以实际情况为准。
