java微信小程序短链接生成

要在Java中生成微信小程序的短链接,您需要使用微信的短链接API。这需要您先在微信公众平台上申请并获取API密钥。
具体来说,您可以使用Java的网络编程库(如HttpURLConnection或Apache HttpClient)向微信的短链接API发送HTTP POST请求。请求中需要包含您的API密钥、需要生成短链接的长链接地址、以及一些其他的参数(例如是否需要返回二维码)。
下面是一个使用HttpURLConnection发送HTTP POST请求的示例代码:
```
String apiKey = "your_api_key";
String longUrl = "https://www.example.com";
String apiUrl = "https://api.weixin.qq.com/cgi-bin/shorturl?access_token=ACCESS_TOKEN";
// 构造请求内容
String requestBody = "{\"action\":\"long2short\"," +
"\"long_url\":\"" + longUrl + "\"}";
// 发送请求
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Authorization", "Bearer " + apiKey);
OutputStream outputStream = connection.getOutputStream();
outputStream.write(requestBody.getBytes());
outputStream.flush();
outputStream.close();
// 读取响应
InputStream inputStream = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder response = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
// 处理响应内容
JSONObject jsonObject = new JSONObject(response.toString());
String shortUrl = jsonObject.getString("short_url");
```
在上面的代码中,需要替换ACCESS_TOKEN为实
