具体实施方式
应当理解，此处所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。
本申请提供一种数据传输方法，参照图1，图1为本申请数据传输方法第一实施例的流程示意图。
本申请实施例提供了数据传输方法的实施例，需要说明的是，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。
数据传输方法可应用于发送端中，发送端可以包括诸如手机、平板电脑、笔记本电脑、掌上电脑、个人数字助理（Personal Digital Assistant，PDA）、便捷式媒体播放器（Portable Media Player，PMP）、导航装置、可穿戴设备、智能手环、计步器等移动终端，以及诸如数字TV、台式计算机等固定终端。
数据传输方法包括：
步骤S10，当获取到待传输数据后，对所述待传输数据进行初始化赋值，得到赋值后的所述待传输数据。
当发送端获取到待传输数据后，发送端对待传输数据进行初始化操作，对待传输数据进行赋值，以得到赋值后的待传输数据。其中，预先定义好的JZlib的Zstream对象，待传输数据对应字节数组的信息可存储在Zstream对象的成员变量中。该待传输数据可为发送端需要与接收端进行数据传输过程中，用户手动输入的；或者是预先存储在发送端的数据库中，当发送端需要与接收端进行数据交互时，发送端从其数据库中获取的。JZlib是Zlib的Java版本，Zlib是提供数据压缩用的函式库。在定义JZlib的Zstream对象过程中，可在Java语法中使用new关键字调用一个Java类的构造方法定义该类的一个实例化对象，即定义JZlib的Zstream对象。
在Zstream对象中，设置了几个成员变量用于存储对应的字节数组的信息。Zstream对象中的成员变量分别为：①next_in：存储in Bytes（输入数据）的内容; ②next_in_index：记录in Bytes的起始下标；③avail_in：记录in Bytes的长度；④next_out：存储out Bytes的内容；⑤next_out_index：记录out Bytes（输出数据）的起始下标；⑥avail_out：记录out Bytes的长度。需要说明的是，通过next_in_index和next_out_index对应可以知道输入数据和输出数据中其内容的起始位。如某个输入数据的起始位为3时，表明在输入数据的字符串中，从第3位开始才是该输入数据的真实内容。
进一步地，步骤S10包括：
步骤a，当获取到待传输数据后，将所述待传输数据的数据类型转换成字节数组，并获取所述字节数组的长度。
进一步地，当发送端获取到待传输数据后，发送端将待传输数据的数据类型转换成字节数组，获取该字节数组的字节长度。在本实施例中，用byte[] in Bytes表示字节数组。可以理解的是，待传输数据对应的字节数组即为Zstream对象的输入数据in Bytes。
步骤b，根据所述字节数组的字节长度，按照预设规则确定与所述字节数组对应的目标长度。
当发送端获取到字节数组的字节长度后，发送端按照预设规则确定与该字节数组对应的目标长度。具体地，发送端将字节数组的字节长度进行四舍五入的处理，得到处理后的字节长度，并在处理后的字节长度中加13，得到与该字节数组对应的目标长度。其中，13可根据具体需要设置为其它质数，在本实施例中对该过程中的质数不做具体限制。
步骤c，将所述目标长度定义为所述字节数组的字节长度，以得到赋值后的所述待传输数据。
当发送端得到字节数组对应的目标长度后，将该目标长度定义为字节数组的字节长度，以得到赋值后的待传输数据。需要说明的是，赋值后的待传输数据为更改字节长度后的待传输数据。在Zstream对象中，赋值后的待传输数据即为输出数据out Bytes。
步骤S20，对赋值后的所述待传输数据进行压缩以及加密处理，得到处理后的所述待传输数据。
当发送端得到赋值后的待传输数据后，对赋值后的待传输数据进行压缩以及加密处理，得到处理后的待传输数据。
进一步地，步骤S20包括：
步骤d，获取赋值后的所述待传输数据对应的起始数据。
进一步地，发送端获取赋值后的待传输数据对应的起始数据。具体地，发送端从Zstream对象中取出输出数据的下标位next_out_index，以得到赋值后的待传输数据对应的起始数据，即输出数据的起始下标为待传输数据对应的起始数据。
步骤e，根据所述起始数据对应的长度值，建立一个目标数组，根据所述起始数据进行for循环，以将赋值后的所述待传输数据对应字节数组中的值逐一赋值待所述目标数组中，得到压缩后的所述待传输数据。
当发送端得到赋值后的待传输数据对应的起始数据后，将该起始数据作为长度值，建立一个目标数组byte[] return Bytes，作为最后的返回值，并根据起始数据进行for循环，将赋值后的待传输数据对应字节数组中的值逐一赋值到return Bytes中，即return Bytes[i]=out Bytes[i]，得到压缩后的待传输数据。
步骤f，采用预设的加密算法，对压缩后的所述待传输数据进行加密，得到处理后的所述待传输数据。
当发送端得到压缩后的待传输数据后，发送端采用预设的加密算法，对压缩后的待传输数据进行加密，得到加密后的待传输数据，即得到处理后的待传输数据。预设的加密算法包括但不限于3DES，DES（Data Encryption Algorithm，数据加密标准）、SHA（Secure Hash Algorithm，安全散列算法）、AES（Advanced Encryption Standard，高级加密标准）、ECC（Elliptic Curves Cipher，椭圆曲线密码）和MD5（Message-Digest Algorithm 5，信息-摘要算法5）等。其中，3DES是三重数据加密算法（TDEA，Triple Data Encryption Algorithm）块密码的通称，又称Triple DES。在本实施例中，优先采用3DES加密算法，3DES算法采用3个不同密钥对同一个分组数据块进行3次加密，以提高加密后数据的强度。
进一步地，步骤f包括：
步骤f1，将压缩后的所述待传输数据转换成预设进制对应的字符串，并获取预存的密钥。
当发送端得到压缩后的待传输数据后，发送端将压缩后的待传输数据转换预设进制对应的字符串，并获取预存的密钥。在本实施例中，根据预设加密算法来确定密钥的种类。当预设加密算法为对称加密算法时，对应的密钥为对称密钥；当预设加密算法为非对称加密算法时，对应的密钥为非对称密钥。在本实施例中，发送端可通过使用Java中org.apache.commons.codec.binary.Hex类的encode Hex String方法将压缩后的待传输数据转换成16进制的字符串。需要说明的是，由于一个16进制字符占用4bit（比特），一个byte占用8bit（字节），Java中一个String字符是16bit，因此使用16进制字符串可节省发送端内存空间，另外一个方面16进制字符串使用0-9，a-f表示的，不会存在发送端编码与源程序编码格式不一致导致编码无法识别，而出现乱码的情况。
可以理解的是，在其它实施例中，发送端也可将压缩后的待传输数据转换成8进制，或者其它进制对应的字符串。
步骤f2，根据所述密钥，通过预设的加密算法对所述字符串进行加密，得到处理后的所述待传输数据。
当发送端获取待密钥后，根据该密钥，通过预设的加密算法对应该字符串进行加密，以得到处理后的待传输数据。在本实施例中，加密算法用到JDK中javax.crypto包下面的Cipher类，声明出来的Cipher对象将压缩后的待传输数据进行加密并返回对应的字节数据，从而得到处理后的待传输数据。其中，JDK是 Java 语言的软件开发工具包，主要用于移动设备、嵌入式设备上的java应用程序，Cipher类为加密和解密提供密码功能。
步骤S30，将处理后的所述待传输数据发送给接收端，以供所述接收端在接收到处理后的所述待传输数据后，解析处理后的所述待传输数据，得到所述待传输数据。
当发送端得到处理后的待传输数据后，将处理后的待传输数据发送给接收端。当接收端接收到处理后的待传输数据后，解析处理后的待传输数据，得到未经加密以及未经压缩处理的待传输数据，即得到原始的待传输数据。
接收端解析处理后的待传输数据的过程为：接收端获取解密所需的密钥，并获取Cipher对象，通过该Cipher对象和密钥解密处理后的待传输数据，得到与处理后的待传输数据对应的字节数据，并将该字节数据转换成字符串。需要说明的是，该字符串即为压缩后的待传输数据。在Cipher对象中，包括了加密算法的名称、分组加密的模式以及最后一个分组的填充方法的消息。因此，通过Cipher对象和密钥即可解密处理后的待传输数据，得到压缩后的待传输数据。可以理解的是，当发送端采用的加密算法为对称加密算法时，发送端加密所用密钥与接收端解密所用密钥是相同的；当发送端采用的加密算法为非对称加密算法时，若发送端采用私钥进行加密，接收端则采用对应的公钥进行解密；若发送端采用公钥进行加密，接收端则采用对应的私钥进行解密。
当接收端得到压缩后的待传输数据后，接收端获取JZlib的ZStream对象，根据压缩后的待传输数据对ZStream对象进行初始化，然后定义一个Byte的List对象，通过for循环解压缩压缩后的待传输数据，得到对应的字节数据，并将所得的字节数据存储至该List对象中，将List对象中的字节数据赋值到字节数组中，以得到解压后的待传输数据，即得到原始的待传输数据。接收端根据压缩后的待传输数据对ZStream对象进行初始化的具体过程为：将压缩后的待传输数据转为字节数组byte[] in Bytes，根据in Bytes的长度四舍五入后，再加13得到输出数据out Bytes的字节数组长度out Length，然后定义长度为out Length的字节数组out Bytes。
需要说明的是，List对象中存储的元素是byte字节，接收端在解压缩的过程中会得到ZStream对象中的out Bytes字节数组，然后以ZStream.next_out_index为长度进行for循环遍历操作，将out Bytes字节数组中的字节逐一添加到list对象中，循环结束添加完毕后，此时list对象中的数据是已解密解压缩后的明文数据的字符，最后需要新建一个长度为list.size()的字节数组byte[]，将list对象中的byte数据逐一赋值到新建的字节数组中，最后用new String(byte[])获取完整的明文字符串。
本实施例通过发送端对需要传输的数据赋值后，对需要传输的数据进行加密处理以及压缩处理，得到压缩加密后的数据，将压缩加密后的数据传输给接收端，对发送端和接收端之间需要传输的数据进行压缩加密的双重安全处理，提高了发送端和接收端之间所传输数据的安全性，保护发送端和接收端之间所传输的数据不为非法分子所窃取。
进一步地，提出本申请数据传输方法第二实施例。
所述数据传输方法第二实施例与所述数据传输方法第一实施例的区别在于，参照图2，数据传输方法还包括：
步骤S40，检测所述待传输数据是否满足压缩条件。
当发送端获取到待传输数据后，发送端检测待传输数据是否满足压缩条件。
进一步地，步骤S40：
步骤g，将所述待传输数据对应的字节数组按照位运算中的左移或者右移算法转换成目标字节数组。
当发送端获取到待传输数据后，发送端调用一个DEFLATE方法，将ZStream对象作为DEFLATE方法的输入参数，将字节数组in Bytes按照位运算中的左移算法或者右移算法生成一个新的字节数组，即将待传输数据对应的字节数组按照位运算中的左移算法或者右移算法转换成目标字节数组。其中，左移或者右移对应的位数可根据具体需要而设置，在本实施例中不做具体限制。DEFLATE是同时使用了LZ77算法与哈夫曼编码（Huffman Coding）的一个无损数据压缩算法。LZ77编码是一种基于字典的、“滑动窗”的无损压缩算法。可以理解的是，在本实施例中，发送端也可调用其它压缩算法，将ZStream对象作为其它压缩算法的输入参数。
步骤h，将所述目标字节数组赋值到预置对象的输出数据成员变量中，并检验所述预置对象中的数据是否满足预设条件。
当发送端得到目标字节数组后，发送端将目标字节数组填充到ZStream对象的next_out成员变量中，即将目标字节数组赋值到预置对象的输出数据成员变量中，对next_out的内容和长度进行校验，并根据校验结果返回一个int类型的值，根据该int类型的值确定ZStream对象中的数据是否满足预设条件。在本实施例中，预置对象为ZStream对象。其中，next_out成员变量中所存储的是赋值后的待传输数据。当检测到赋值后的待传输数据的内容与初始化之前，即原始的待传输数据内容一致，且赋值后的待传输数据的长度与原始的待传输数据对应关系正确时，发送端则得到待传输数据满足预设条件校验结果，即确定预置对象中的输出数据成员变量满足预设条件；若检测到赋值后的待传输数据的内容与原始的待传输数据内容不一致，和/或赋值后的待传输数据的长度与原始的待传输数据对应关系错误，发送端则得到待传输数据未满足预设条件校验结果，即确定预置对象中的输出数据成员变量未满足预设条件。
可以理解的是，赋值后的待传输数据的长度是由原始待传输数据的长度经过预设规则所确定的，因此，赋值后的待传输数据的长度和原始待传输数据的长度是存在一定的对应关系的。
步骤i，若所述输出数据成员变量满足预设条件，则确定所述待传输数据满足所述压缩条件。
若发送端确定预置对象中的输出数据成员变量满足预设条件，发送端则确定待传输数据满足压缩条件，可以对该待传输数据进行压缩处理。具体地，发送端可根据int类型的值来确定预置对象中的数据是否满足预设条件。如当发送端确定预置对象中的数据满足预设条件，会返回一个int类型的值，如返回“0”，并将该值显示在其显示屏中，以提示用户待传输数据满足压缩条件。此时，用户可根据发送端显示屏中的“0”确定待传输数据满足压缩条件。
步骤j，若所述输出数据成员变量未满足所述预设条件，则确定所述待传输数据未满足所述压缩条件。
若发送端确定预置对象中的输出数据成员变量未满足预设条件，发送端则确定待传输数据未满足压缩条件，不可以对该待传输数据进行压缩处理。具体地，发送端可根据int类型的值来确定预置对象中的数据是否满足预设条件。如当发送端确定预置对象中的数据满足预设条件，会返回一个int类型的值，如返回“1”，并将该值显示在其显示屏中，用户可根据发送端显示屏中的“1”确定待传输数据未满足压缩条件。
若所述待传输数据满足所述压缩条件，则执行步骤S20。
若发送端确定待传输数据满足压缩条件，发送端则对赋值后的待传输数据进行压缩以及加密处理，得到处理后的待传输数据。
进一步地，若发送端确定待传输数据未满足压缩条件，发送端则不执行压缩待传输数据的压缩操作。
本实施例通过在对待传输数据进行压缩处理之前，检测待传输数据是否满足压缩条件。只有当待传输数据满足压缩条件时，才执行压缩操作，避免了在压缩待传输数据过程中，压缩待传输数据不成功时，发送端才知道待传输数据不可以进行压缩处理，提高了压缩待传输数据的成功率。
进一步地，提出本申请数据传输方法第三实施例。
所述数据传输方法第三实施例与所述数据传输方法第二实施例的区别在于，参照图3，数据传输方法还包括：
步骤S50，若所述待传输数据未满足所述压缩条件，则输出提示信息，以根据所述提示信息提示用户所述待传输数据未满足所述压缩条件。
当发送端确定待传输数据未满足压缩条件后，发送端在其显示屏中输出提示信息，以根据该提示信息提示用户待传输数据未满足压缩条件。其中，提示信息可以以文字或者语音等形式输出，在本实施例中对提示信息的输出形式不做限制。如发送端可在其显示屏中输出“数据不满足压缩条件”的文字信息提示用户。
进一步地，当发送端在输出提示信息提示用户待传输数据未满足压缩条件时，发送端可在提示信息中携带提示用户是否发送该待传输数据的信息。当发送端接收到用户确认发送待传输数据的确认指令后，发送端直接将所获取的待传输数据发送给接收端，即将未经压缩处理和加密处理的待传输数据发送给接收端；当发送端接收到用户确认不发送待传输数据给接收端的确认指令后，发送端不将待传输数据发送给接收端。
本实施例通过当确定待传输数据未满足压缩条件后，发送端输出提示信息，根据该提示信息提示用户待传输数据未满足压缩条件，以供用户可以及时知道待传输数据未满足压缩条件。

发送模块30，用于将处理后的所述待传输数据发送给接收端，以供所述接收端在接收到处理后的所述待传输数据后，解析处理后的所述待传输数据，得到所述待传输数据。
本实施例通过发送端的赋值模块10对需要传输的数据赋值后，处理模块20对需要传输的数据进行加密处理以及压缩处理，得到压缩加密后的数据，发送模块30将压缩加密后的数据传输给接收端，对发送端和接收端之间需要传输的数据进行压缩加密的双重安全处理，提高了发送端和接收端之间所传输数据的安全性，保护发送端和接收端之间所传输的数据不为非法分子所窃取。
