短信接入示例
短信接入示例
功能概述
短信服务(Short Message Service)是网易网易云通信为用户提供的一种通信服务的能力，目前支持验证码类短信、通知类短信、运营类短信、语音类短信、国际短信等是事务性短信。
短信接口为标准的HTTP接口，以下示例包含了常见语言如何发起HTTP请求，帮助开发者更高效的接入短信接口。
注：最重要的四个参数，务必参考计算示例服务器API，否则会出现{"desc":"bad http header","code":414}
参数
参数说明
AppKey
开发者平台分配的appkey
Nonce
随机数(最大长度128个字符)
CurTime
当前UTC时间戳，从1970年1月1日0点0 分0 秒开始到现在的秒数(String)
CheckSum
SHA1(AppSecret + Nonce + CurTime),三个参数拼接的字符串，进行SHA1哈希计算，转化成16进制字符(String，小写)
Appkey，Appsecret获取步骤：
成为云信开发者
创建应用
打开App Key管理
短信URL请求：(务必请将您创建的模板和对应的URL请求对应上，否则会出现404错误)
管理后台创建的模板分为：

常见错误码
所有的短信HTTP请求均有response，response有两部分组成，
第一部分是code，代表code具体的内容，成功还是失败
第二部分是desc或者msg，代表错误原因描述(非code=200的情况，才会有desc)
414参数错误
1. checksum
{"desc":"checksum","code":414}
典型的checksum计算错误，需要自行核对计算checksum的参数算法，前提是保证这个appSecret是属于您在管理后台的应用下的。
2. bad http header
{"desc":"bad http header","code":414}
典型的请求http header计算错误，需要自行核对请求header中的4个参数，分别为Appkey，Nonce，Curtime，CheckSum。(上述文档可以查询这4个参数)
3. 'mobiles' should be json format
{"code":414,"msg":"'mobiles' should be json format"}
典型的mobiles的参数传的有问题，因为文档的要求是jsonArray的格式，所以需要保证这个mobiles的参数是jsonArray的。例如：Java的格式为“['xxx','xxxx']”，其他代码方式请自行参考解决。
4. 'params' should be json format
{"code":414,"msg":"'params' should be json format"}
典型的params的参数传的有问题，因为文档的要求是jsonArray的格式，所以需要保证这个params的参数是jsonArray的，并且要注意你的参数数量，例如：Java的格式为“['xxx','xxxx']”，其他代码方式请自行参考解决。
5. sms template specify by id not found
{"code":414,"msg":"sms template specify by id not found"}
典型的短信模板与您的Appkey对应不上，导致参数传的有问题。需要保证当前审核过的短信模板，与您的这个当前应用下的Appkey是一一对应的，否则就会出现这样的错误。
404对象不存在
1. template id not exist
{"code":404,"msg":"template id not exist"}
典型的短信模板与您发起的http请求的url不一致，首先要检查管理后台审核的模板是否与您的请求一致，比如通知类模板请求的url是sendTemplate.action，验证码模板请求的url是sendcode.action，这些在上述文档中都有描述，可以查看。
400 HTTP错误
1. HTTP Status 400
这个错误是HTTP常见错误， 400 请求出错 由于语法格式有误，服务器无法理解此请求，一般出现的情况，都是短信请求的参数body与短信请求的URL不匹配导致的，只要参考检查上述文档中的URL，以及文档中的body参数即可。
余额预警阙值
余额预警阙值，先可以登录管理后台，点击左侧“总览”，当前页有个“”余额预警”，可以自行配置，余额提醒。
短信回执抄送
现在云信支持短信的回执抄送，抄送详细解释在Server端文档，配置抄送地址在管理后台中的当前应用下，有个“消息抄送配置”，配置地址可以是地址，也可以是域名。短信的抄送只要通道给了回执，原封不动的给抄送出去，包括发送成功和失败(如黑名单，空号等等)，如果通道那边没有给回执，那我们这边就不会抄送。另外，如果短信被反垃圾了，也不会有抄送，这个相当于，短信都没投递到通道服务商那边。
