Description

设备连接方法、装置及连接码生成方法 技术领域
本申请涉及通信技术领域，具体而言，涉及一种设备连接方法、装置及连接码生成方法。
背景技术
互联网中的每个设备都对应有一个IP地址，要实现两台设备的连接，就需要知道对方的IP地址并访问特定服务的端口。而连接码的作用就是将IP地址以及端口序号编码成可识别的连续符号(包括数字、字母等)，这样一台设备就可以将自身信息便捷地展示给另一台设备，从而将两台设备进行连接。
相关技术中，连接码一般有纯数字以及数字字母混合两种形式，纯数字的连接码通常长度较长，较为浪费编码空间；而数字字母混合的连接码虽然长度稍短，但会提高连接码的输入难度，二者均不利于用户的使用体验。
针对上述的问题，目前尚未提出有效的解决方案。

实施例1
根据本申请实施例，提供了一种设备连接方法的实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中 执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图1是根据本申请实施例的设备连接方法，如图1所示，该方法包括如下步骤：
步骤S102，获取目标局域网中第一设备的目标信息，其中，目标信息中包括第一设备的IP地址以及用于与目标局域网中的第二设备进行连接的目标服务端口的序号。
在本申请一些可选的实施例中，可以先对第一设备的所有可用服务端口进行编号，然后确定其中用于与第二设备进行连接的目标服务端口的序号，同时，确定第一设备的IP地址，将该IP地址与目标服务端口的序号作为第一设备的目标信息。
可选地，目标信息中还包括第一设备生成的目标校验码，该目标校验码为第一设备在预设的取值范围内随机生成的数字，具体取值范围可由用户进行定义，如0-15。在本申请一些可选的实施例中，目标校验码会随时间动态刷新，即第一设备会每隔一个固定的时间段后生成新的目标校验码，以保证设备连接的安全性。
步骤S104，依据目标信息生成目标连接码，其中，目标连接码对应多个连接信息，每个连接信息中包括一个IP地址及一个服务端口序号，多个连接信息中包括目标信息。
可以理解地，目标连接码是依据目标信息生成，因此目标连接码对应的多个连接信息中必然包括目标信息。其中，在目标信息中包括目标校验码时，目标连接码所对应的每个连接信息中还包括一个校验码。
在本申请一些可选的实施例中，依据目标信息生成目标连接码的过程如下，其包括步骤S1040-S1048：
步骤S1040，依据目标服务端口的序号生成二进制的第一编码。
具体地，先获取第一设备的可用服务端口序号的第一取值范围，将第一取值范围平均分为第一预设数量段取值范围，将其中最小的一段取值范围作为第二取值范围，其中，第二取值范围为第一编码的取值范围。
之后，再判断目标服务端口的序号是否在第二取值范围内；若目标服务端口的序号在第二取值范围内，则依据目标服务端口的序号生成第一编码；若目标服务端口的序号不在第二取值范围内，则确定第二取值范围中与目标服务端 口的序号对应的第一目标值，依据第一目标值生成第一编码。
例如，第一设备的可用服务端口有4个，分别将其编号为0、1、2、3，则第一取值范围为0-3，将其平均分为2段，得到第二取值范围为0-1，生成的第一编码将在0-1内取值；假设目标服务端口的序号为1，其在第二取值范围0-1内，则直接依据1生成二进制的第一编码为1；假设目标服务端口的序号为3，其不在第二取值范围0-1内，则需要先确定其对应的第一目标值为3-2＝1(2表示第二取值范围中包括2个数)，之后依据1生成二进制的第一编码为1。
可以发现，第一编码的1可对应多个服务端口序号，其既可以表示服务端口序号为1，也可以表示服务端口序号为3，具体的含义需要在连接时采用重试的方式确定。通过上述过程，就可以将原本需要2bit(0-3对应二进制00-11)的第一编码缩短为1bit(0-1对应二进制0-1)来表示。
在本申请一些可选的实施例中，还可以不生成第一编码，即目标信息中不包括目标服务端口序号，在进行设备连接时，直接依次与第一设备的多个可用服务端口尝试进行连接。
步骤S1042，依据目标校验码生成二进制的第二编码。
与生成第一编码的过程类似，先获取第一设备的可用校验码的第三取值范围，将第三取值范围平均分为第二预设数量段取值范围，将其中最小的一段取值范围作为第四取值范围，其中，第四取值范围为第二编码的取值范围。
之后。再判断目标校验码是否在第四取值范围内；若目标校验码在第四取值范围内，则依据目标校验码生成第二编码；若目标校验码不在第四取值范围内，则确定第四取值范围中与目标校验码对应的第二目标值，依据第二目标值生成第二编码。
例如，用户预设可用校验码的第三取值范围为0-15，将其平均分为2段，得到第四取值范围0-7，生成的第二编码将在0-7内取值；假设目标校验码为6，其在第四取值范围0-7内，则直接依据6生成二进制的第一编码为110；假设目标校验码为13，其不在第四取值范围0-7内，则需要先确定其对应的第二目标值为13-8＝5(8表示第二取值范围中包括2个数)，之后依据5生成二进制的第一编码为101。
若将第三取值范围0-15平均分为4段，得到第四取值范围0-3，生成的第二编码将在0-3内取值；假设目标校验码为2，其在第四取值范围0-3内，则直接依据2生成二进制的第一编码为10；假设目标校验码为6，其不在第四取值范 围0-3内，则需要先确定其对应的第二目标值为6-4＝2(4表示第二取值范围中包括4个数)，之后依据2生成二进制的第一编码为10；假设目标校验码为13，其不在第四取值范围0-3内，则需要先确定其对应的第二目标值为13-4-4-4＝1，之后依据1生成二进制的第一编码为1。
通过上述过程，就可以将原本需要4bit(0-15对应二进制0000-1111)的第二编码缩短为3bit(0-7对应二进制000-111)甚至2bit(0-3对应二进制00-11)来表示。
步骤S1044，依据第一设备的IP地址生成二进制的第三编码。
在本申请一些可选的实施例中，可以对不同类型的IP地址采用不同的编码策略，因此可以先确定第一设备的IP地址类型，其中，IP地址类型包括A类地址，B类地址和C类地址，A类地址范围为10.0.0.0至10.255.255.255，B类地址范围为172.16.0.0至172.31.255.255，C类地址范围为192.168.0.0至192.168.255.255，其中，每类IP地址均包括四个字节。
之后，对第一设备的IP地址的任意一个字节，确定该字节的第五取值范围，将第五取值范围平均分为第三预设数量段取值范围，将其中最小的一段取值范围作为第六取值范围；判断该字节的值是否在第六取值范围内；若该字节的值在第六取值范围内，则依据该字节的值生成与该字节对应的子编码；若该字节的值不在第六取值范围内，则确定第六取值范围中与该字节的值对应的第三目标值，依据第三目标值生成与该字节对应的子编码；最后，依据第一设备的IP地址的各个字节所对应的子编码，确定第三编码，通常，将第一设备的IP地址的四个字节所对应的子编码进行组合，得到第三编码。
例如，第一设备的IP地址为192.168.126.128，则可以对每一字节均进行如下处理：确定第五取值范围为0-255，将其平均分为2段，得到第六取值范围为0-127；第一字节192不在第六取值范围0-127内，则确定其对应的第三目标值为192-128＝64，之后依据64生成二进制的子编码为1000000；第二字节168不在第六取值范围0-127内，则确定其对应的第三目标值为168-128＝40，之后依据40生成二进制的子编码为0101000；第三字节126在第六取值范围0-127内，则直接依据126生成二进制的子编码为1111110；第四字节128不在第六取值范围0-127内，则确定其对应的第三目标值为128-128＝0，之后依据0生成二进制的子编码为0000000；最终，将四个字节对应的子编码组合，即得到28bit的第三编码1000000010100011111100000000，比原先的32bit缩短了4bit。
需要说明的是，对第一设备的IP地址的不同字节，所确定的第五取值范围可以不同，将第五取值范围平均划分的段数也可以不同，若划分为一段，即表示直接依据该字节的值生成二进制的子编码。
例如，第一设备的IP地址类型为B类地址时，由于第二字节的取值范围为16-31，因此，对第二字节进行处理时，可以将0-31作为第五取值范围，将其平均分为2段，得到第六取值范围为0-15；假设第一设备的IP地址为172.31.255.255，由于31不在第八取值范围0-15内，则确定其对应的第四目标值为31-16＝15，之后依据15生成二进制的子编码为1111，其位数仅4bit。
由于IP地址通常从前段分区域，例如10.xx.xx.xx可能分为10.0.xx.xx-10.2.xx.xx和10.12.xx.xx-10.16.xx.xx，因此，在确定各字节对应的子编码时，可以将前两个字节的第五取值范围平均分为2段，按上述过程确定子编码；将后两个字节的第五取值范围平均分为1段，即直接依据字节的值生成子编码。
在本申请一些可选的实施例中，由于A类IP地址的第一字节(即标志位)固定为10，B类IP地址的第一字节固定为172，C类IP地址的前两字节固定为192.168，因此，在第一设备的IP地址类型为A类地址或B类地址时，将第一设备的IP地址的后三个字节所对应的子编码进行组合，得到第三编码；在第一设备的IP地址类型为C类地址时，将第一设备的IP地址的后两个字节所对应的子编码进行组合，得到第三编码。在进行设备连接时，直接采用重试的方式确定IP地址的标志位即可。
例如，第一设备的IP地址为192.168.126.128，为C类地址，则只需将其第三字节对应的子编码1111110和第四字节对应的子编码0000000进行组合，得到该IP地址对应的第三编码为11111100000000。
步骤S1046，将第一编码、第二编码及第三编码进行组合，得到二进制的第四编码。
步骤S1048，将第四编码由二进制转化为十进制，得到目标连接码。
假设第一设备用于与第二设备连接的目标服务端口序号为3，生成的校验码为15，IP地址为10.255.255.255，如果在生成连接码时直接用真实值表示这些信息，则得到的第一编码为11，第二编码为1111，第三编码为00001010111111111111111111111111，将其组合得到第四编码11111100001010111111111111111111111111共38bit，转化为十进制的目标连接码为270767489023，其位数为12bit。若在采用上述的目标连接码生成过程处理 时，确定每个取值范围均平均分为两段，且IP地址的第一字节省略，则分别得到第一编码为1，第二编码为111，第三编码为111111111111111111111，将其组合得到第四编码1111111111111111111111111共25bit，转化为十进制的目标连接码为33554431，其位数仅为8bit。可以看出，通过上述过程得到的目标连接码的位数被大大缩短，减少了额外的空间占用。
步骤S106，将目标连接码发送至第二设备，并依据目标连接码对应的目标信息与第二设备建立连接。
在本申请一些可选的实施例中，将目标连接码发送至第二设备，由第二设备解析目标连接码对应的多个连接信息；接收第二设备依据多个连接信息发送的多个连接请求，其中，每个连接信息对应一个连接请求；确定每个连接请求所对应的连接信息是否与目标信息相同，在连接信息与目标信息相同时与第二设备建立连接。
具体地，将目标连接码发送至第二设备后，第二设备会依据目标连接码生成过程反向解析该目标连接码对应的多个连接信息，并依据每个连接信息向第一设备发送一个连接请求，尝试与第一设备建立连接；第一设备每接收到一个连接请求后，会将该连接请求对应的连接信息与自身的目标信息进行比较，若二者相同，即连接信息中包括第一设备用于与第二设备进行连接的目标服务端口的序号、第一设备生成的目标校验码以及第一设备的IP地址时，则与第二设备建立连接。
例如，第一设备用于与第二设备连接的目标服务端口序号为3，生成的校验码为15，IP地址为10.255.255.255，其依据上述连接码生成过程生成连接码33554431，并发送给第二设备。第二设备依据上述连接码生成过程反向解析该连接码，首先将其转化为二进制1111111111111111111111111，确定服务端口序号对应的第一编码为1，则认为第一设备的服务端口序号可能为1，可能为3；确定校验码对应的第二编码为111，即认为第一设备的校验码可能为7，可能为15；确定IP地址对应的第三编码为111111111111111111111，则认为第一设备的IP地址第二字节可能为127，可能为255；第三字节可能为127，可能为255；第四字节可能为127，可能为255；由于第二字节不满足B、C类地址，则确定为A类地址，第一字节为10；将上述信息进行组合，即得到多个连接信息，如服务端口序号为1，校验码为7，IP地址为10.127.127.127。其中，由于第一设备与第二设备运行在同一局域网中，第二设备在解析IP地址的第一字节时，可 以优先考虑与自身IP地址的第一字节相同的字节。
第二设备依据每个连接信息生成一个对应的连接请求与第一设备尝试进行连接，并不断进行重试。第一设备每接收到一个连接请求后，会将该连接请求对应的连接信息与自身的目标信息进行比较，若二者不同，则继续判断下一个连接请求，若二者相同，则与第二设备建立连接。
在本申请实施例中，首先获取第一设备的目标信息，包括IP地址以及用于与第二设备进行连接的目标服务端口的序号；然后依据目标信息生成目标连接码，目标连接码对应多个连接信息；将目标连接码发送至第二设备，采用重试的方式从目标连接码对应的多个连接信息中确定出目标信息，依据目标信息与第二设备建立连接。本申请基于时间换空间的思想，通过用一个连接码对应多个连接信息，以重试的方式来缩短连接码的位数，减少额外空间占用，从而解决了设备连接时纯数字连接码输入长度过长，数字字母混合的连接码输入不便技术问题。
实施例2
根据本申请实施例，还提供了一种连接码生成方法的实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图2是根据本申请实施例的设备连接方法，如图2所示，该方法包括如下步骤：
步骤S202，获取第一设备中用于与第二设备进行连接的目标服务端口序号、目标校验码及IP地址。
在本申请一些可选的实施例中，可以先对第一设备的所有可用服务端口进行编号，然后确定其中用于与第二设备进行连接的目标服务端口的序号；确定第一设备生成的目标校验码，该目标校验码为第一设备在预设的取值范围内随机生成的数字，具体取值范围可由用户进行定义，如0-15，可选地，目标校验码会随时间动态刷新，即第一设备会每隔一个固定的时间段后生成新的目标校验码，以保证设备连接的安全性；同时，确定第一设备的IP地址。
步骤S204，依据目标服务端口序号生成二进制的第一编码，第一编码对应多个服务端口序号，多个服务端口序号中包括目标服务端口序号。
具体地，先获取第一设备的可用服务端口序号的第一取值范围，将第一取 值范围平均分为第一预设数量段取值范围，将其中最小的一段取值范围作为第二取值范围，其中，第二取值范围为第一编码的取值范围。之后，再判断目标服务端口的序号是否在第二取值范围内；若目标服务端口的序号在第二取值范围内，则依据目标服务端口的序号生成第一编码；若目标服务端口的序号不在第二取值范围内，则确定第二取值范围中与目标服务端口的序号对应的第一目标值，依据第一目标值生成第一编码。
步骤S206，依据目标校验码生成二进制的第二编码，第二编码对应多个校验码，多个校验码中包括目标校验码。
具体地，先获取第一设备的可用校验码的第三取值范围，将第三取值范围平均分为第二预设数量段取值范围，将其中最小的一段取值范围作为第四取值范围，其中，第四取值范围为第二编码的取值范围。之后。再判断目标校验码是否在第四取值范围内；若目标校验码在第四取值范围内，则依据目标校验码生成第二编码；若目标校验码不在第四取值范围内，则确定第四取值范围中与目标校验码对应的第二目标值，依据第二目标值生成第二编码。
步骤S208，依据第一设备的IP地址生成二进制的第三编码，第三编码对应多个IP地址，多个IP地址中包括第一设备的IP地址。
在本申请一些可选的实施例中，可以先确定第一设备的IP地址类型，每类IP地址均包括四个字节；对第一设备的IP地址的任意一个字节，确定该字节的第五取值范围，将第五取值范围平均分为第三预设数量段取值范围，将其中最小的一段取值范围作为第六取值范围；判断该字节的值是否在第六取值范围内；若该字节的值在第六取值范围内，则依据该字节的值生成与该字节对应的子编码；若该字节的值不在第六取值范围内，则确定第六取值范围中与该字节的值对应的第三目标值，依据第三目标值生成与该字节对应的子编码；最后，依据第一设备的IP地址的各个字节所对应的子编码，确定第三编码，通常，将第一设备的IP地址的四个字节所对应的子编码进行组合，得到第三编码。
其中，对第一设备的IP地址的不同字节，所确定的第五取值范围可以不同，将第五取值范围平均划分的段数也可以不同，若划分为一段，即表示直接依据该字节的值生成二进制的子编码。
在本申请一些可选的实施例中，由于A类IP地址的第一字节(即标志位)固定为10，B类IP地址的第一字节固定为172，C类IP地址的前两字节固定为192.168，因此，在第一设备的IP地址类型为A类地址或B类地址时，将第一 设备的IP地址的后三个字节所对应的子编码进行组合，得到第三编码；在第一设备的IP地址类型为C类地址时，将第一设备的IP地址的后两个字节所对应的子编码进行组合，得到第三编码。在进行设备连接时，直接采用重试的方式确定IP地址的标志位即可。
步骤S210，将第一编码、第二编码及第三编码进行组合，得到二进制的第四编码。
步骤S212，将第四编码由二进制转化为十进制，得到目标连接码。
在本申请实施例中，通过获取第一设备中用于与第二设备进行连接的目标服务端口序号、目标校验码及IP地址，并分别依据目标服务端口序号生成第一编码，依据目标校验码生成第二编码，依据第一设备的IP地址生成第三编码，其中，通过让每个编码对应多个信息来缩短编码的位数，从而缩短最终组合得到的目标连接码的长度，减少额外空间占用，进而解决了设备连接时纯数字连接码输入长度过长，数字字母混合的连接码输入不便技术问题。
实施例3
