php生成的json传给android gson无法解析

android php

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>
Copy after login

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>
Copy after login
<code>public class Model{
    public int id;
    public String token;
    public Contacts[] contacts;
}

public class Contacts {
    public String name;
    public String tel;
}


</code>
Copy after login

最简单的做法,是用Map去解析你的json,遇到对象就进行强制转换,虽然不优雅,但通用。针对那些不太清楚自己的Bean写法的人比较好用。上面的回复都是bean的对应写法。
