1.php json_encode 生成的json传输给android 用gson无法解析
2.$arr = array('token'=>'111','id'=>'1','contacts'=>array('name'=>'11','tel'=>'188'));
就是这种数组中包含数组 转换成json 发送给 android android用gson无法解析。
PHP多维关联数组用json_encode生成json串 android用gson不识别
用索引数组生成的则可以

推荐在Android使用GsonFormat集成到AS中,可以很方便的生产符合的javaBean,如果你Android端解析代码没写错得话就不会有什么问题的。
下面是使用该工具对应你的json生成的javaBean:
<code>public class ceshi { /** *token : 111 *id : 1 *contacts : {"name":"11","tel":"188"} */ private String token; private String id; /** *name : 11 *tel : 188 */ private ContactsBean contacts; public String getToken() { return token; } public void setToken(String token) { this.token = token; } public String getId() { return id; } public void setId(String id) { this.id = id; } public ContactsBean getContacts() { return contacts; } public void setContacts(ContactsBean contacts) { this.contacts = contacts; } public static class ContactsBean { private String name; private String tel; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getTel() { return tel; } public void setTel(String tel) { this.tel = tel; } } }</code>
要不你把转换出来的json和你用来接收json的实体类发一下?
不同语言,不同版本解析 json 的库可能实现上有所不同
php 是内置,所以很容易调用,有些语言要使用第三方的类库
所以干脆问 android 拿接收到的字符串是怎么样的,然后你在用php json_decode,看看能不能解析
gson不能解析php的json字符串,主要看,Android客户端接收到的json字符串是否完整,如果完整,在使用gson的时候,转换成java对象,虽然gson支持泛型,但是至少你要提供json字符串对应的javaBean实例,否则转换一定失败。
<code>$arr = array('token'=>'111','id'=>'1','contacts'=>array('name'=>'11','tel'=>'188')); </code>
在java中应该对应一个class,该类必须有String token,int id,Object contacts,而contacts对应两一个类,该类必须有String name,String tel属性。
Test.java
<code>package test.joyven.com; public class Test { private int id; private String token; private Contacts contacts; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getToken() { return token; } public void setToken(String token) { this.token = token; } public Contacts getContacts() { return contacts; } public void setContacts(Contacts contacts) { this.contacts = contacts; } } </code>
Contacts.java
<code>package test.joyven.com; public class Contacts { private String name; private String tel; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getTel() { return tel; } public void setTel(String tel) { this.tel = tel; } } </code>
把json串打印出来,看看json结构,我估计是你java bean的格式不对。
<code>Model[] models = new Gson().fromJson(JsonStr, Model[].class); </code>
<code>public class Model{ public int id; public String token; public Contacts[] contacts; } public class Contacts { public String name; public String tel; } </code>
最简单的做法,是用Map

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
