.NET 阿里云短信服务开发 code: 400, TemplateCode is mandatory for this action. request id: E7B0E694-6B41-5506-AAE3-443F1BAB3452

.NET 阿里云短信服务开发时遇到错误代码 400，并提示 `TemplateCode` 是必需的，这通常意味着你在发送短信请求时缺少模板码 (Template Code)。阿里云的 SMS SDK 或 API 要求你在调用发送短信功能时提供预先设置好的模板码，这个码对应预定义的短信内容模板。 具体步骤可能包括： 1. **创建短信模板**：登录阿里云控制台，进入短信服务管理界面，创建一个新的短信模板并获取到对应的模板码（TemplateCode）。 2. **引用 SDK**：如果你使用的是阿里云的 .NET SDK，确保已经正确引用了 SDK 并初始化配置。 3. **发送短信代码示例**： ```csharp using Alibaba Cloud.Dns.Sms.V20200622; using Alibaba.OpenTea; // ... var smsClient = new SmsClient(YOUR_ACCESS_KEY_ID, YOUR_ACCESS_KEY_SECRET, RegionId.CnHangzhou); string templateCode = "YOUR_TEMPLATE_CODE"; // 替换为实际的模板码 string phoneNumber = "+861234567890"; // 发送号码，替换为手机号 var request = new SendSmsRequest PhoneNumber = phoneNumber, SignName = "您的签 bs.report_no, bs.sample_id, bs.test_id, bs.service_type, bs.sample_name, bs.total_fee, bs.receivable_fee, bs.sample_no, bs.ranges, bs.grade, bs.sample_remark AS remark, bs.factory, bs.item_name, bs.apply_dept, bs.specification, bs.factory_number, bs.calibrat_point, bs.mandatory_flag, bs.inspection_type, bs.report_org_name, bs.plan_complete_date, bs.standard_instrument_name, bs.bleeding_site_name, bs.arrive_date, DATEDIFF( bs.plan_complete_date, NOW()) AS surplus_days, bs.order_no, bs.order_type, bs.customer_name, bs.order_id, bs.business_type, bs.group_id, bs.group_name, bs.item_id, bs.is_merge, bs.pass_time, bs.audit_time, bs.report_id, bs.compile_time, bs.generate_time, bs.pass_user_name, bs.audit_user_name, bs.compile_user_name, bs.report_state, bs.is_just_certificate, bs.label_price, bs.labor_cost, bs.product_type, bs.batch_number, bs.original_number, bs.type_no, bs.template_id, bs.template_version, bs.standard_instrument_id, bs.standard_instrument_name, bs.report_query_code, bs.test_user_id, bs.test_user_name, bs.test_time, bs.review_user_id, bs.review_user_name, bs.review_time, bs.or_number, bs.test_result, bs.test_result_text, bs.test_date, bs.test_address, bs.result_value, bs.unit, bs.test_dept_id, bs.test_dept_name, bs.sample_mass, bs.form, bs.color, bs.clarity, bs.amplification_detection, bs.precious_metal, bs.remarks, bs.photo, bs.identifying_code, bs.diamond_quality, bs.hand_ring, bs.craft, bs.instrument_photo, bs.customer_item_basis, bs.quality_photo, bs.check_point, bs.check_code, bs.mass_unit, bs.manufacturer_name, bs.manufacturer_addr, bs.result_sample_describe AS sampleDescribe, bs.test_rule AS metalRuleIdsStr, bsa.attach_id view_sample_info bs JOIN bus_sample_report bsr ON bs.report_id = bsr.id JOIN bus_sample sa ON bsr.sample_id = sa.id JOIN bus_sample_attr bsa ON sa.id = bsa.id 需要按照bs.report_no 的整数来从小到大进行排序
