如何从HttpServletRequest创建okhttp3请求？

implementation 'com.squareup.okhttp3:okhttp:版本号'

HttpServletRequest request = ...; // 获取HttpServletRequest对象的方式根据具体的项目框架而定

OkHttpClient client = new OkHttpClient();

Request.Builder requestBuilder = new Request.Builder()
        .url(request.getRequestURL().toString())
        .method(request.getMethod(), null);

// 设置请求头
Enumeration<String> headerNames = request.getHeaderNames();
while (headerNames.hasMoreElements()) {
    String headerName = headerNames.nextElement();
    String headerValue = request.getHeader(headerName);
    requestBuilder.addHeader(headerName, headerValue);
}

// 设置请求体（如果有）
if (request.getMethod().equals("POST") || request.getMethod().equals("PUT")) {
    RequestBody requestBody = RequestBody.create(null, request.getInputStream().readAllBytes());
    requestBuilder.method(request.getMethod(), requestBody);
}

Request httpRequest = requestBuilder.build();

try (Response response = client.newCall(httpRequest).execute()) {
    // 处理响应
    String responseBody = response.body().string();
    // ...
}
