解决Okhttp只能获取一次responsebody的问题

okhttp通过response.body().string() 获取字符串类型的responsebody

源码分析

  public final String string() throws IOException {
    try (BufferedSource source = source()) {
      Charset charset = Util.bomAwareCharset(source, charset());
      return source.readString(charset);
    }
  }


@Override public void close() {
    Util.closeQuietly(source());
  }

ResponseBody，其实现了 Closeable 接口，通过复写 close() 方法来 关闭并释放资源，关闭 ResponseBody 子类所持有的 BufferedSource 接口对象，当我们第一次调用 response.body().string() 时，OkHttp 将响应体的缓冲资源返回的同时，调用 closeQuietly() 方法默默释放了资源

获取responseBody

private static String getResponseBody(Response response) throws IOException {
     BufferedSource source = response.body().source();
     source.request(Long.MAX_VALUE);
     Buffer buffer = source.getBuffer();
     String responseBody = buffer.clone().readUtf8();
     return responseBody;
 }

获取requestBody

private static String getRequestBody(Request request) throws IOException {
        Buffer buffer = new Buffer();
        if (request.body() != null) {
            request.body().writeTo(buffer);
            return buffer.clone().readUtf8();
        }
        return "";
    }
