本文介绍了一个使用Java进行文件上传接口测试的方法。通过构建HTTP请求，设置必要的头部信息，并使用MultipartEntityBuilder添加文件和文本参数，实现了对指定URL的文件上传功能。在响应状态为200的情况下，读取并打印了服务器返回的内容。

   @Test
    public void uploadFileImpl() throws Exception {
        File file = new File("1514267205448.png");
        if (file.length() <= 0) return;
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        CloseableHttpResponse httpResponse = null;
        HttpPost httpPost = new HttpPost(HttpUserLoginTest.developUrl + "/image/upload");

        HttpEntity httpEntity = multipartEntityBuilder.build();
        httpPost.setEntity(httpEntity);
        httpResponse = httpClient.execute(httpPost);
        HttpEntity responseEntity = httpResponse.getEntity();
        int statusCode = httpResponse.getStatusLine().getStatusCode();
        if (statusCode == 200) {
            BufferedReader reader = new BufferedReader(new InputStreamReader(responseEntity.getContent()));
            StringBuffer buffer = new StringBuffer();
            String str = "";
            while ((str = reader.readLine()) != null) {
                buffer.append(str);
