前言：

2天前小编发现微信小程序用户：【寒帅斌】提出了一个关于“我在使用微信的【服务端】APP下单的示例代码的时候一直报错？”的问题,在问题中开发者寒帅斌对该问题做了如下阐述：

问题类型：

API和组件:

问题描述：

@RequestMapping(“/ceshi”)
public String ceshi() throws IOException {
CloseableHttpClient httpClient = HttpClients.createDefault();

//请求URL
HttpPost httpPost = new HttpPost(“https://api.mch.weixin.qq.com/v3/pay/transactions/app”);
// 请求body参数
String reqdata = “{“
+ “”time_expire”:”2018-06-08T10:34:56+08:00″,”
+ “”amount”: {“
+ “”total”:1,”
+ “”currency”:”CNY””

+ “”unit_price”:828800″
+ “},”
+ “{“
+ “”goods_name”:”iPhoneX 256G”,”
+ “”wechatpay_goods_id”:”1001″,”
+ “”quantity”:1,”
+ “”merchant_goods_id”:”100025545″,”
+ “”unit_price”:828800″

+ “],”

+ “”scene_info”: {“

+ “”payer_client_ip”:”14.23.150.211″”
+ “}”
+ “}”;
StringEntity entity = new StringEntity(reqdata,“utf-8”);
entity.setContentType(“application/json”);
httpPost.setEntity(entity);
httpPost.setHeader(“Accept”, “application/json”);

//完成签名并执行请求
CloseableHttpResponse response = httpClient.execute(httpPost);

try {
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) { //处理成功
System.out.println(“success,return body = “ + EntityUtils.toString(response.getEntity()));
} else if (statusCode == 204) { //处理成功，无返回Body
System.out.println(“success”);
} else {
System.out.println(“failed,resp code = “ + statusCode+ “,return body = “ + EntityUtils.toString(response.getEntity()));
throw new IOException(“request failed”);
}
} finally {
response.close();
}
return EntityUtils.toString(response.getEntity());
}
这是代码 (有一些隐私东西不方便查看如商户号之类的)

一直报这个错是怎么回事
