httpclient 例子
作为一个AI语言模型,我无法提供wechatpay-apache-httpclient的完整用例,但我可以为您提供一些参考资料和建议:
1. 我们可以在官方文档中找到wechatpay-apache-httpclient的使用方法。可以参考https://wechatpay-api.gitbook.io/wechatpay-api-v3/chang-jian-wen-ti/httpclient-ru-he-shi-yong
2. 首先,需要在项目中引入wechatpay-apache-httpclient的依赖,例如在Maven项目中,可以在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>com.wechatpay</groupId>
<artifactId>wechatpay-apache-httpclient</artifactId>
<version>6.5.6</version>
</dependency>
```
3. 接下来,我们需要配置httpClient,包括设置连接池、连接超时时间、读取超时时间等。例如:
```java
PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager();
connectionManager.setMaxTotal(100); // 最大连接数
connectionManager.setDefaultMaxPerRoute(20); // 单个路由最大连接数
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(5000) // 连接超时时间
.setSocketTimeout(5000) // 读取超时时间
.build();
CloseableHttpClient httpClient = HttpClients.custom()
.setConnectionManager(connectionManager)
.setDefaultRequestConfig(requestConfig)
.build();
```
4. 然后,我们可以使用httpClient发送请求,并处理响应结果。例如:
```java
HttpPost httpPost = new HttpPost("https://api.mch.weixin.qq.com/v3/pay/transactions/jsapi");
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Wechatpay-Serial", "XXXXXXXXXXX");
httpPost.setHeader("Authorization", "WECHATPAY2-SHA256-RSA2048 " + accessToken);
StringEntity entity = new StringEntity(requestJson, "UTF-8");
httpPost.setEntity(entity);
HttpResponse httpResponse = httpClient.execute(httpPost);
int statusCode = httpResponse.getStatusLine().getStatusCode();
String responseJson = EntityUtils.toString(httpResponse.getEntity(), "UTF-8");
if (statusCode == HttpStatus.SC_OK) {
// 处理成功响应结果
} else {
// 处理失败响应结果
}
```
以上代码仅为示例,具体使用方法还需根据实际情况进行调整。同时,为了保证代码的可读性和可维护性,建议使用封装好的工具类来处理httpClient请求和响应结果。
