关于业务代码Java调用服务端hub serving部署的structure_table报错

[freezehe]

问题描述 / Problem Description

如题：我在centos7上通过hub serving 启动了structure_table 服务，服务是调通了，但是返回结果是：{"msg":"list index out of range","results":"","status":"101"}不知道是什么意思，肯定是没有成功，服务是通的。 模型如下截图

服务是调通了，截图如下：

运行环境 / Runtime Environment

• OS: centos7 部署服务，windows ide java业务调用服务
• Paddle: 2.6.1
• PaddleOCR: 2.7.3

复现代码 / Reproduction Code

我的java代码如下： package com.freeze;

import org.apache.commons.codec.binary.Base64; import org.apache.commons.lang3.StringEscapeUtils; import org.apache.http.HttpEntity; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.util.EntityUtils; import org.json.JSONArray; import org.json.JSONObject;

import java.io.File; import java.io.FileInputStream; import java.io.IOException;

public class PaddleHubTableClient {

public static void main(String[] args) {
    String serverUrl = "http://172.16.12.229:8868/predict/structure_table"; // PaddleHub Serving默认URL
    File imageFile = new File("D:\\1\\test-ocr\\test-ocr-0629\\src\\main\\resources\\img\\table.jpg");

    try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
        HttpPost uploadFile = new HttpPost(serverUrl);

        // Read image file and encode to Base64
        FileInputStream fileInputStream = new FileInputStream(imageFile);
        byte[] imageBytes = new byte[(int) imageFile.length()];
        fileInputStream.read(imageBytes);
        String encodedImage = Base64.encodeBase64String(imageBytes);
        fileInputStream.close();

        // Create JSON object with the Base64 encoded image
        JSONObject json = new JSONObject();
        json.put("images", new String[]{encodedImage});

        // Set the request content type to application/json
        StringEntity requestEntity = new StringEntity(json.toString(), "UTF-8");
        uploadFile.setEntity(requestEntity);
        uploadFile.setHeader("Content-Type", "application/json");

        // Execute the request
        CloseableHttpResponse response = httpClient.execute(uploadFile);
        HttpEntity responseEntity = response.getEntity();
        String responseString = EntityUtils.toString(responseEntity, "UTF-8");
        response.close();

        // Print the response
        System.out.println("Original Response:");
        System.out.println(responseString);

        // Parse the response and decode the text
        JSONObject jsonResponse = new JSONObject(responseString);
        if (jsonResponse.has("status") && jsonResponse.getInt("status") != 0) {
            System.out.println("Error Status: " + jsonResponse.getInt("status"));
            System.out.println("Error Message: " + jsonResponse.getString("msg"));
        } else if (jsonResponse.has("results")) {
            JSONArray resultsArray = jsonResponse.getJSONArray("results");
            for (int i = 0; i < resultsArray.length(); i++) {
                JSONArray textRegions = resultsArray.getJSONArray(i);
                for (int j = 0; j < textRegions.length(); j++) {
                    JSONObject textRegion = textRegions.getJSONObject(j);
                    String text = textRegion.getString("text");
                    String decodedText = StringEscapeUtils.unescapeJava(text);
                    System.out.println("Decoded Text: " + decodedText);
                }
            }
        } else {
            System.out.println("Unexpected response structure.");
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}

完整报错 / Complete Error Message
