什么是GoQR的二维码生成器?

二维码 API

您可以在 api.qrserver.com 使用我们的 QR 码生成器 Web API 生成和解码/读取 QR 码图形。

什么是GoQR的二维码生成器接口？

由服务使用方的应用程序发起，以Restful风格为主、通过公网HTTP协议调用GoQR的二维码生成器 ，从而实现程序的自动化交互，提高服务效率。

GoQR的二维码生成器有哪些核心功能？

  1. 通过互联网创建二维码（开发自己的二维码生成器)
  2. 通过互联网读取/扫描二维码（开发自己的二维码阅读器）)
  3. 带有徽标的社交二维码（Facebook或Twitter徽标/二维码中嵌入的图像）（即将推出）
  4. 创建彩色二维码
  5. 专业二维码打印文件格式（矢量图形、二维码EPS和SVG）)
  6. 高性能服务器
  7. 通过 HTTPS （SSL/TLS） 进行加密通信

GoQR的二维码生成器的核心优势是什么？

  1. 随时更改网站地址 （URL）：借助动态二维码，可以随时更改存储的目标 URL，即使您的营销材料已经打印出来。调整您的广告活动或简单地纠正错别字。
  2. 二维码跟踪和分析：跟踪和分析功能为所有动态二维码提供广泛的实时统计信息（例如，按日期/时间、浏览器、（移动）操作系统、地理位置划分的扫描次数）。因此，您可以看到哪些二维码广告活动成功，哪些应该调整。领先于您的竞争对手，为您自己的客户准备统计数据，只需点击几下即可告知他们您的移动营销策略是否成功。
  3. 链接应用商店：使用一个二维码即可轻松访问您的应用程序所在的所有 App Store。只需将不同移动操作系统的 App Store 地址存储在 QR-Server（iOS、Android、Windows Phone、Blackberry 等）中即可。QR-Server 在扫描二维码后识别用户的操作系统，然后他会自动重定向到合适的 App Store。
  4. 二维码存档：您创建的所有二维码都将被存储并清楚地表示。因此，在创建二维码后，您可以轻松地将其下载为 PNG / JPEG / GIF 或 EPS / SVG，以获得专业的打印质量。您甚至可以在每次下载时调整代码的布局（例如颜色），而无需将所有数据重新输入到二维码生成器中，只是因为您需要另一种颜色的图像。
  5. QR服务器的其他功能：：
    • 100%基于网络（无需安装，无需维护）
    • 由于打印矢量图形格式（EPS、SVG）而获得完美的打印质量
    • 无二维码扫描限制
    • 将创建的图形转售给您的客户
    • 无广告

在哪些场景会用到GoQR的二维码生成器？

1.网站链接分享：生成指向特定网页的二维码，方便用户通过扫描快速访问网站。

2. 产品信息展示：为产品生成包含详细信息的二维码，用户扫描后可以查看产品详情、价格、评价等。

3. 电子票务：用于生成电子票证的二维码，用户在入场时通过扫描二维码进行验证。

4. 移动支付：生成支付二维码，用户扫描后可以直接进行支付操作。
