服务器返回的HTTP响应代码：Dropbox API的URL为400

问题描述

我正在尝试为项目使用DropBox API，当我创建连接时，控制台中会出现错误400。

代码是：

String url = "https://api.dropBoxapi.com/2/files/get_Metadata";
    
    try {
        
        
        HttpURLConnection openConnection = (HttpURLConnection) new URL(url).openConnection();
        //if(url.contains(" "))
            //url = url.replace(" ","%20");
        openConnection.setRequestMethod("POST");
        openConnection.setRequestProperty("Authorization","Bearer <REDACTED>");
        openConnection.setRequestProperty("Content-Type","application/json");
        openConnection.setRequestProperty("Accept","application/json");
        openConnection.setDoOutput(true);
        String jsonBody = "{\r\n" + "    \"path\": \"\",\r\n" + "    \"recursive\": true,\r\n"
                + "    \"include_media_info\": true,\r\n" + "    \"include_deleted\": false,\r\n"
                + "    \"include_has_explicit_shared_members\": false,\r\n"
                + "    \"include_mounted_folders\": true,\r\n" + "    \"include_non_downloadable_files\": true\r\n"
                + "}";
        
        try (OutputStream os = openConnection.getoutputStream()) {
            byte[] input = jsonBody.getBytes("utf-8");
            os.write(input,input.length);
        }

我在旧主题中搜索了添加IF循环以替换url中的空格的解决方案，但没有成功。有什么建议吗？
