请求参数

签名规则

sign = md5(appid + "#" + data + "#" + time + "#" + appkey + "#" + nostr)

appkey 为密钥私钥，仅参与签名，不参与请求传输。

默认返回（图片流，format=image）

返回 PNG 图片二进制数据，Content-Type: image/png，可直接用于 <img src="..."> 或保存为文件。

format=url（返回图片地址）

{
            "code": 1,
            "info": "请求响应成功！",
            "data": {
                "code": 1,
                "info": "生成成功",
                "data": {
                    "url": "/safefile/barcode/abc123.png"
                }
            }
        }

format=base64（返回 Base64 编码）

{
            "code": 1,
            "info": "请求响应成功！",
            "data": {
                "code": 1,
                "info": "生成成功",
                "data": {
                    "base64": "data:image/png;base64,iVBORw0KGgo..."
                }
            }
        }

失败返回

{
            "code": 1,
            "info": "请求响应成功！",
            "data": {
                "code": 0,
                "info": "配额已用完，请升级套餐"
            }
        }
