没有从 HttpClient 获得完整的 HTTP 响应

Question

我似乎没有从 httpclient 获得完整的 json 响应。我正在打 api 我在本地运行就像这样：

curl -i -X POST http://localhost:8098/<api location> -F "files=@<filename>"

我的回复是这样的：

{"data":[<bunch of json>]

但是当我尝试使用 httpclients post 完全相同的文件时，我得到了这个响应：

{"data":[]}

我做错了什么？这是我的 java 代码。谢谢！

public CloseableHttpResponse submit (File file) throws IOException {
    CloseableHttpClient client = HttpClients.createDefault();
    HttpPost post = new HttpPost(API_LOCATION + API_BASE);
    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.addBinaryBody("ISO xml file", file, ContentType.APPLICATION_OCTET_STREAM, file.getName());
    HttpEntity multipartEntity = builder.build();
    post.setEntity(multipartEntity);

    CloseableHttpResponse response = client.execute(post);
    System.out.println("response: " + IOUtils.toString(response.getEntity().getContent(),"UTF-8"));
    client.close();
    return response;
}

Answer 1

正如 Andreas 和 Danilo 在评论中提到的那样：

In curl you name the field files, but in Java you name it ISO xml file. Since server only looks for files, it see nothing, and responds with nothing. -

What about the parameter's name? On curl you used 'files' and on http client you used 'ISO xml file'. Try changing it to 'file'. -

我需要将“ISO xml 文件”更改为“文件”并且成功了。
