Description

Http重定向状态码捕获方法、装置和计算机设备 技术领域
本申请涉及互联网技术领域，特别是涉及一种Http重定向状态码捕获方法、装置、计算机设备和存储介质。
背景技术
随着互联网技术的发展，出现了小程序技术，小程序，是指一种搭载于其他平台(如微信平台、百度平台和头条平台)，无需下载和安装就可以在平台中使用的应用程序。
在Web系统中，基于安全等方面考虑，很多请求需要用户处于登陆状态(称之为受限资源)。在对受限资源处理的时候，常用的做法是，在判定用户没有处于登陆状态时，强制跳转到登陆页。然而，由于小程序底层请求并不是像浏览器请求，小程序的请求是不支持Http(Hypertext transfer protocol，超文本传输协议)重定向状态码的。传统的解决方式是，先调用服务端的接口判断用户的登陆状态。对于小程序端的，由于所有请求都会多一次判断用户是否登陆的请求，多一次请求，必然造成响应的延迟。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
可以理解，本申请所使用的术语“第一”、“第二”等可在本文中用于描述各种元件，但这些元件不受这些术语限制。这些术语仅用于将第一个元件与另一个元件区分。举例来说，在不脱离本申请的范围的情况下，可以将第一客户端称为第二客户端， 且类似地，可将第二客户端称为第一客户端。第一客户端和第二客户端两者都是客户端，但其不是同一客户端。此外，可以理解，本申请所使用的术语“或者/和”，描述关联对象的关联关系，表示可以存在三种关系，例如，A或者/和B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或者”的关系。
本申请提供的Http重定向状态码捕获方法，可以应用于如图1-1所示的应用环境中。该应用环境中包括终端102、网络104和业务系统106，终端102和业务系统106之间均可以通过网络104实现可通信的连接。该由终端102、网络104和服务器106构成的网络系统可以是基于互联网，也可以基于局域网，还可以基于互联网和局域网的组合网，在此不做赘述。
终端102可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。同时，图1-1中示出的是终端102包括终端1022和终端1024等两个终端的情况，但本申请并不对终端102的数量进行限制，也可以包括更多或者更少的终端。终端102上运行有小程序应用，小程序应用是指不需要下载安装即可使用的应用，例如，微信环境下运行的微信小程序、百度环境下运行的百度小程序。
网络104用于实现终端102与业务系统106之间的网络连接，可以包括多种类型的有线或无线网络。网络104都可以包括互联网、局域网(“LAN”)、广域网(“WAN”)、内部网、移动电话网络、虚拟专用网(VPN)、蜂窝式或其它移动通信网络、蓝牙、NFC或其任何组合。网络104进行数据传输时也会基于相应的通讯协议，例如网页浏览器接收网页相应的业务代码时会基于HTTP通讯协议，移动应用程序接收的业务代码时可以基于Websocket通讯协议。
业务系统106可以包括一个或者多个服务器，例如，图1-1中示出的是业务系统106包括服务器1062和服务器1064等两个服务器的情况，但本申请并不对服务器的数量进行限制，也可以包括更多或者更少的服务器。每个服务器可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
本申请提供的Http重定向状态码捕获方法，还可以应用于如图1-2所示的应用环境中。该应用环境中除了包括图1-1所示的终端102、网络104和业务系统106，还可以包括网关108。网关108部署网关层，该网关层一般是在WEB服务器前一层。网关108作为计算机设备，统一将业务系统对各个终端运行的小程序的重定向响应进行响应报文的转换，以保证各个终端运行的小程序能够对业务系统的重定向状态码进行响 应。此外，业务系统106的数量也可以为多个。多个业务系统106对应同一个网关。
在一个实施例中，如图2所示，提供了一种Http重定向状态码捕获方法，以该方法应用于图1-2中的网关为例进行说明，包括以下步骤：
步骤202，获取第一状态码，第一状态码为第一响应报文的响应头中的状态码，第一响应报文为向业务系统发起Http请求后、业务系统返回的响应报文；
这里，状态码指状态代码，一般是指为所接收的请求(例如，网页点击)分配的3位数代码，一般为Http状态码(Http Status Code)，Http状态码是用以表示网页服务器超文本传输协议响应状态的3位数字代码。这里，Http请求用于请求第一响应报文。
具体地，终端(或者说终端上运行的小程序)向业务系统发送业务请求后，业务系统根据该业务请求得到第一响应报文；网关向业务系统发起Http请求以获取该第一响应报文，在获得该第一响应报文后，获取该第一响应报文的响应头中的状态码，即第一状态码。
步骤204，在第一状态码为重定向状态码时，根据预设的报文协议格式以及第一状态码，构建第二响应报文，第一状态码承载在第二响应报文的报文体中；
这里，重定向状态码一般是指HTTP状态码中与重定向相关的状态码，例如，301、302、303和307等状态码。重定向(Redirect)就是通过各种方法将各种网络请求重新定个方向转到其它位置，例如：网页重定向或者域名的重定向。
这里，报文协议格式是网关和以下的接收方之间预先约定好的报文协议的格式，该报文协议格式至少包括第一状态码的配置方式。
具体地，网关首先判断第一状态码是否为重定向状态码，若是，则根据预设的报文协议格式以及第一状态码，构建第二响应报文，其中，第一状态码承载在第二响应报文的报文体中。根据需要，判断第一状态码是否为重定向状态码的过程也可以由其他设备完成，网关获得判断结果。
步骤206，返回第二响应报文，第二响应用于指示接收方根据报文协议格式获取重定向状态码。
具体地，网关向终端(或者说终端上运行的小程序)返回第二响应报文，
上述Http重定向状态码捕获方法中，是获取第一状态码，第一状态码为第一响应报文的响应头中的状态码，第一响应报文为向业务系统发起Http请求后、业务系统返回的Http响应报文，在第一状态码为重定向状态码时，根据预设的报文协议格式以及第一状态码，构建第二响应报文，第一状态码承载在第二响应报文的报文体中，返回 第二响应报文，第二响应用于指示接收方根据报文协议格式获取重定向状态码。本实施例中，按照预设的报文协议格式进行了响应报文转换，将原本不被接收方支持的重定向状态码承载在第二响应报文的报文体中，得到了第二响应报文，接收方(例如，小程序端)可以根据报文协议格式获取重定向状态码。如此，不需要再调用服务度端的判断用户登录状态接口，一方面可以减少判断用户登录状态接口的调用频次，另一方面可以也可以减小响应延迟，可以提升用户体验。
在一个实施例中，上述的第二响应报文的报文头中承载有第二状态码，该第二状态码为接收方支持的且与第一状态码不同的状态码。
这里，第二状态码可以是200状态码，200状态码表示已成功处理了请求的状态代码。根据需要，第二状态码也可以是除200状态码以外的其他状态码，例如，其他2xx状态码。
在一个实施例中，如图3所示，上述的在第一状态码为重定向状态码时，根据预设的报文协议格式以及第一状态码，构建第二响应报文，可以包括如下步骤：
步骤302，在第一状态码为重定向状态码时，获取第一响应报文的响应头中的网络位置信息；
这里，网络位置信息也可以称为网页地址信息，是互联网上标准的资源的地址(Address)。该网络位置信息往往是响应报文的响应头中的Location。
具体地，网关首先判断第一状态码是否为重定向状态码，若是，则获取第一响应报文的响应头中的网络位置信息。
步骤304，根据预设的报文协议格式、第一状态码和网络位置信息，构建第二响应报文，第二响应报文的报文体中还承载有网络位置信息。
这里，报文协议格式还包括报文协议格式的配置方式。其中，网络位置信息作为重定向的网页地址信息(redirectUrl)。
具体地，网关可以按照预设的报文协议格式，将第一状态码和网络位置信息配置在第二响应报文的报文体中。一般地，可以将第一状态码和网络位置信息配置在同一报文体中，对于同一响应报文包括多个报文体的情况，也可以将第一状态码和网络位置信息配置在不同的报文体中。
采用本实施例的方案，由于第二响应报文的报文体中还承载有网络位置信息，可以方便终端(或者说终端上运行的小程序)发起对更改网络位置信息(即重定向)的调用。
由于考虑到在请求重定向时，一般需要将上次请求的cookie携带上，在一个实施例中，如图4所示，上述的在第一状态码为重定向状态码时，根据预设的报文协议格式以及第一状态码，构建第二响应报文，可以包括如下步骤：
步骤402，在第一状态码为重定向状态码时，获取第一响应报文的响应头中的网络位置信息以及该第一响应报文的响应头中的Cookie数据；
其中，Cookie，有时也用其复数形式Cookies，指某些网站为了辨别用户身份、进行session跟踪而储存在用户本地终端上的数据(通常经过加密)。
步骤404，根据预设的报文协议格式、第一状态码、网络位置信息以及Cookie数据，构建第二响应报文，第二响应报文的报文体中还承载有网络位置信息以及有Cookie数据。
采用本实施例的方案，可以进一步方便终端(或者说终端上运行的小程序)发起对更改网络位置信息的调用。
在一个实施例中，如图5所示，提供了一种Http重定向状态码捕获方法，以该方法应用于图1中的网关为例进行说明，包括以下步骤：
步骤502，根据预设的用户代理筛选规则或者/和描述信息筛选规则，对接收到的响应报文进行筛选；
其中，用户代理筛选规则和描述信息筛选规则都可以根据实际需要设定。例如，设定一用户代理标识集合，若接收到的响应报文对应的用户代理标识是该用户代理标识集合中的一个，则判定满足用户代理筛选规则。例如，也可以设定一描述信息集合，若接收到的响应报文对应的描述信息与该描述信息集合中的任意一条描述信息相匹配，则判定满足描述信息筛选规则。
步骤504，在接收到的响应报文满足用户代理筛选规则或者/和描述信息筛选规则时，将接收到的响应报文作为第一响应报文；
步骤506，获取第一状态码，第一状态码为第一响应报文的响应头中的状态码，第一响应报文为向业务系统发起Http请求后，业务系统返回的响应报文；
步骤508，在第一状态码为重定向状态码时，根据预设的报文协议格式以及第一状态码，构建第二响应报文，第一状态码承载在第二响应报文的报文体中；
步骤510，返回第二响应报文，第二响应用于指示接收方根据报文协议格式获取重定向状态码。
本实施例中步骤506、步骤508和步骤510可以对应的参照上述的步骤202、步骤 204和步骤206的描述，在此不予赘述。
本实施例中，对接收到的响应报文进行过滤，可以节约小程序端消耗的流量。
在一个实施例中，本申请的Http重定向状态码捕获方法还可以包括步骤：在第一状态码为非重定向状态码时，返回第一响应报文。
这里，非重定向状态码是指与重定向不相关的状态码。
本实施例中，在第一状态码为非重定向状态码时，不对第一响应报文进行修改，直接将该第一响应报文返回给接收方。接收方对于直接返回的第一响应报文，按照原本的业务处理逻辑进行处理即可。
需要说明的是，上述实施例中均是以将本申请的Http重定向状态码捕获方法应用于网关为例，同时，是以上述的接收方为终端、终端上运行有小程序应用、且小程序应用根据报文协议格式获取重定向状态码为例，进行说明。但根据实际需要，上述的各个实施例中的Http重定向状态码捕获方法也可以应用于图1-1或者图1-2中的业务系统或者业务系统中的某一个或者多个服务器，即上述的各个实施例中的各个步骤的执行主体为业务系统或者业务系统中的某一个或者多个服务器。
对于应用于网关，可以由网关统一对各个小程序的重定向响应进行响应报文的转换，以使得各个终端运行的各个小程序均能够对业务系统的重定向状态码进行响应，一方面不需要调用服务端的判断用户登录状态接口，对服务端的业务无侵入，另一方面，也不需要每个服务器单独配置以实现对重定向响应的转换，可以节约配置成本。
根据上述实施例中Http重定向状态码捕获方法，在一个实施例中，如图6所示，提供了一种Http重定向状态码捕获方法，以该方法应用于图1-1或者图1-2中的终端为例进行说明，该终端上运行有小程序应用，该方法包括以下步骤：
步骤602，接收响应报文；
步骤604，在确定接收到的响应报文为第二响应报文时，根据预设的报文协议格式获取承载在第二响应报文的报文体中的重定向状态码，该重定向状态码为第一状态码，第二响应报文根据该报文协议格式以及第一状态码构建。
此外，在确定接收到的响应报文为第一响应报文时，按照小程序应用对第一响应报文原本的处理逻辑进行处理。
对于第二响应报文的报文体中还承载有网络位置信息时，可以根据网络位置信息发起重定向请求，对于第二响应报文的报文体中还承载有Cookie数据时，发起的重定向请求的响应头中携带有该Cookie数据。
关于终端侧Http重定向状态码捕获方法的具体限定可以参见上文中对于网关侧的Http重定向状态码捕获方法的限定，在此不再赘述。
为了便于理解本发明的方案，以下以网关和小程序应用(以下称为小程序端)的交互为例进行说明。
本实施例中的报文协议格式为：{“code”：“重定向状态码”，“redirectUrl”：“Location”，“cookie”：“Cookie”}，同时，制定协议，当下游业务系统返回重定向状态码时，约束返回结果为json格式的报文协议，即该报文协议格式，其中，json是一种轻量级的数据交换格式。
该报文协议格式中的code为请求业务系统发生重定向的响应头里面的状态码(Status)，如301、302等。redirectUrl为请求业务系统发生重定向的响应头里面的网络位置信息(Location)。cookie为请求业务系统发生重定向的响应头里面的Cookie。
小程序统一网关(相当于上述的网关)，可以采用OpenResty(nginx+lua)搭建，网关层是小程序使用，在统一接入层，可以通过用户代理(userAgent)和描述信息(refer)来限制是小程序的流量，才到小程序统一网关，网关层使用httpc库调用下游的业务系统接口，解析得到业务系统接口的响应头，当响应头里面的响应码为重定向状态码时，将响应头里面的状态码、网络位置信息和Cookie按照上述的报文协议格式，返回在响应报文的报文体里，给该响应报文的状态码为200。其中，code是标记真实业务的响应状态码，redirectUrl是重定向响应头里面的Location，方便小程序下次发起对该URL的调用，cookie是第一次请求的响应头里面的cookie，因为在请求重定向(redirectUrl)的时候，需要将上次请求的cookie携带。
小程序端通过返回json格式的报文中的code知道业务系统实际返回状态码，发现是重定向的状态码，就取json格式的报文里面的Cookie放到请求头里，请求json里面的redirectUrl地址，从而得到业务数据返回。
网关层可以采用nginx+lua的httpc发起业务系统的http请求，如图7所示，本实施例中Http重定向状态码捕获方法包括以下步骤：
步骤702，网关判断业务系统的响应报文中的状态码是否是重定向状态码，若是，则进入步骤704，若否，则进入步骤706；
这里，业务系统的响应报文相当于上述的第一报文。具体地，小程序端发出业务请求到业务系统，业务系统根据该业务请求得到响应报文，网关向业务系统请求该响应报文，具体地，网关可以使用httpclient调用业务系统的接口URL。网关层获取业务 系统的响应报文的响应头里面的状态码，判断是否是重定向相关的状态码(301、302、303、307等)。
步骤704，网关获取业务系统的响应报文的响应头里面的状态码、网络位置信息和Cookie，将对应的值，按照约定的报文协议格式，构建并返回以200为状态码的报文。
具体地，可以获取业务系统的响应报文的响应头里面的状态码(Status)、网络位置信息(Location)和Cookie，将状态码、网络位置信息、Cookie对应的值，按照约定的协议格式，构建以200为状态码的报文：{“code”：”重定向状态码”，”redirectUrl”：”Location”，”cookie”Cookie”}中，并返回。
步骤706，网关将业务系统的响应报文返回；
具体地，如果状态码是非重定向状态码，网关将业务系统的响应报文返回。
步骤708，小程序端接收到网关发送的响应报文，解析接收到的响应报文的响应头信息；
对于解析结果，有两种情况：1、正常非重定向的响应；2、经过网关处理的原始业务重定向的响应，也就是重定向协议，格式：{“code”：”重定向状态码”，”redirectUrl”：”Location”，”cookie”Cookie”}。
步骤710，小程序端在接收到的是非重定向的响应报文时，按照该响应报文对应的业务处理逻辑进行处理；
步骤712，小程序端在接收到的是重定向的响应报文时，根据该响应报文的报文体中的网络位置信息发起重定向请求。
其中，将cookie设置在重定向请求的请求头里，发起以响应报文的报文体中的网络位置信息为新地址信息的重定向请求。
制定一套解决小程序不支持http状态码为重定向的协议。采用OpenResty(nginx+lua)搭建的网关层捕获http重定向状态码，返回约定协议{“code”：”重定向状态码”，”redirectUrl”：”Location”，”cookie”Cookie”}，可以采用lua的httpc库解析http协议接口的响应头里的Status、Location、Cookie数据，并按照约束协议，返回结果。使用该协议，通过网关层处理，将业务系统的重定向的响应转换为200状态码的响应。
应该理解的是，虽然图2-7的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2-7 中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
