使用uniapp离线打包底座时获取getApplicationContext()的方法

在对应的类中静态引入以下方法即可：

import static io.dcloud.common.util.ReflectUtils.getApplicationContext;

1	import static io.dcloud.common.util.ReflectUtils.getApplicationContext;

然后再对应的业务逻辑中直接使用getApplicationContext()即可获取到。

事实上我用jd-gui查看其编译后代码，看见好像这种工具类也能自己写，其代码如下（未验证过）：

import android.context.Context;

public static Context getApplicationContext(){
	Context context = null;
	try{
		Context = (Context)Class.forName("android.app.ActivityThread").getDeclaredMethod("currentApplication",new Class[0]).invoke((Object)null, new Object[0]);
	}catch(Exception e){
		null.printStackTrace();
	}
}

import android.context.Context;

public static Context getApplicationContext(){

Context context = null;

try{

Context = (Context)Class.forName("android.app.ActivityThread").getDeclaredMethod("currentApplication",new Class[0]).invoke((Object)null, new Object[0]);

}catch(Exception e){

null.printStackTrace();

}

使用uniapp的安心打包制作ios安装文件时出现PKCS12 import (wrong password?)

假如你确定你的证书密码是对的，就是死活不成功，出现如下提示：

那有可能是因为导出p12证书的时候密码过于简单，不符合要求，导致后续证书使用时的安检失败引起的。请重新导出新的、且符合密码强度要求的p12证书。

Android调用原生文件管理器来选择文件

在activity即可:

public class UploadActivity  extends Activity {

        super.onCreate(savedInstanceState);

        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("*/*"); //设置类型，任意类型
        intent.addCategory(Intent.CATEGORY_OPENABLE);

        this.startActivityForResult(intent, REQUEST_CODE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //if (requestCode == REQUEST_CODE && resultCode == 200) {
        if (data == null) {
            // 用户未选择任何文件，直接返回
            return;
        }

        Uri uri = data.getData(); // 获取用户选择文件的URI

        String path =  uri.getPath();

使用okhttp3时忽略所有证书

1、新建一个SSLSocketClient.java类：

import java.security.SecureRandom;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class SSLSocketClient {

    //获取这个SSLSocketFactory
    public static SSLSocketFactory getSSLSocketFactory() {
        try {
            SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, getTrustManager(), new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    //获取TrustManager
    private static TrustManager[] getTrustManager() {
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(X509Certificate[] chain, String authType) {
                    }

                    @Override
                    public void checkServerTrusted(X509Certificate[] chain, String authType) {
                    }

                    @Override
                    public X509Certificate[] getAcceptedIssuers() {
                        return new X509Certificate[]{};
                    }
                }
        };
        return trustAllCerts;
    }

    //获取HostnameVerifier
    public static HostnameVerifier getHostnameVerifier() {
        HostnameVerifier hostnameVerifier = new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        };
        return hostnameVerifier;
    }

}

import java.security.SecureRandom;

import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;

import javax.net.ssl.SSLContext;

import javax.net.ssl.SSLSession;

import javax.net.ssl.SSLSocketFactory;

import javax.net.ssl.TrustManager;

import javax.net.ssl.X509TrustManager;

public class SSLSocketClient {

//获取这个SSLSocketFactory

public static SSLSocketFactory getSSLSocketFactory() {

try {

SSLContext sslContext = SSLContext.getInstance("SSL");

sslContext.init(null, getTrustManager(), new SecureRandom());

return sslContext.getSocketFactory();

} catch (Exception e) {

throw new RuntimeException(e);

}

//获取TrustManager

private static TrustManager[] getTrustManager() {

TrustManager[] trustAllCerts = new TrustManager[]{

new X509TrustManager() {

@Override

public void checkClientTrusted(X509Certificate[] chain, String authType) {

}

@Override

public void checkServerTrusted(X509Certificate[] chain, String authType) {

}

@Override

public X509Certificate[] getAcceptedIssuers() {

return new X509Certificate[]{};

}

};

return trustAllCerts;

}

//获取HostnameVerifier

public static HostnameVerifier getHostnameVerifier() {

HostnameVerifier hostnameVerifier = new HostnameVerifier() {

@Override

public boolean verify(String s, SSLSession sslSession) {

return true;

}

};

return hostnameVerifier;

}

2、使用以下代码来构建okhttp3即可：

OkHttpClient.Builder mBuilder = new OkHttpClient.Builder();
mBuilder.sslSocketFactory(SSLSocketClient.getSSLSocketFactory());
mBuilder.hostnameVerifier(SSLSocketClient.getHostnameVerifier());
OkHttpClient client = mBuilder.build();

OkHttpClient.Builder mBuilder = new OkHttpClient.Builder();

mBuilder.sslSocketFactory(SSLSocketClient.getSSLSocketFactory());

mBuilder.hostnameVerifier(SSLSocketClient.getHostnameVerifier());

OkHttpClient client = mBuilder.build();

12306火车购票优先选下铺的方法

1、先在页面空白地方右击“审查元素”

2、在页面代码编辑区域搜索“优先席别”

3、在网页页面出现席别选择，此时选择硬卧，然后右键“硬卧”选项并审查元素

4、在硬卧的span标签后增加以下代码即可：

<select name="passsenger_1_seat-detail_select" id="passenger_1_seat_detail_select" onchange="setseatDetail('1')">
    <option value="0">随机</option>
    <option value="3">上铺</option>
    <option value="2">中铺</option>
    <option value="1">下铺</option>
</select>

uni-app使用H5+调用原生的安卓方法

uni-app代码：

//获取当前Activity，使用H5的方式调用android原生方法，从而启动activity
var main = plus.android.runtimeMainActivity();
//invoke: 调用对象（类对象/实例对象）的方法,调用Android原生方法        
let result = plus.android.invoke('cn.com.sway.test.TestActivity', 'test', main);
//弹窗显示返回结果
uni.showToast({
	title: "调用原生activity返回的结果为：\n" + result,
	icon: 'none',
	duration: 2000
});

//获取当前Activity，使用H5的方式调用android原生方法，从而启动activity

var main = plus.android.runtimeMainActivity();

//invoke: 调用对象（类对象/实例对象）的方法,调用Android原生方法

let result = plus.android.invoke('cn.com.sway.test.TestActivity', 'test', main);

//弹窗显示返回结果

uni.showToast({

title: "调用原生activity返回的结果为：\n" + result,

icon: 'none',

duration: 2000

});

安卓代码：

package cn.com.sway.test;

import android.app.Activity;
import android.widget.Toast;

import java.util.Random;

public class TestActivity extends Activity {

    public static String test(Activity activity, String text){
        Toast.makeText(activity, "来自uni-app的消息："+text, Toast.LENGTH_SHORT).show();
        return "来自android的消息："+(new Random()).nextInt();
    }

}

package cn.com.sway.test;

import android.app.Activity;

import android.widget.Toast;

import java.util.Random;

public class TestActivity extends Activity {

public static String test(Activity activity, String text){

Toast.makeText(activity, "来自uni-app的消息："+text, Toast.LENGTH_SHORT).show();

return "来自android的消息："+(new Random()).nextInt();

}

注意，被调用的安卓方法必须为static静态方法，否则无法被调起。

第一步：首先新建自己的MainActivity

package cn.com.sway.app

import android.os.Bundle;

import io.dcloud.WebAppActivity;

public class MainActivity extends WebAppActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
    public boolean isStreamAppMode() {
        return false;
    }

}

package cn.com.sway.app

import android.os.Bundle;

import io.dcloud.WebAppActivity;

public class MainActivity extends WebAppActivity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

}

public boolean isStreamAppMode() {

return false;

}

注意：

1、务必集成io.dcloud.WebAppActivity这个类

2、必须要有isStreamAppMode方法，如果没有这个方法，会无法正常加载页面

第二部：在AndroidManifest.xml里修改入口Activity

    <activity
            android:name="cn.com.sway.app.MainActivity"
            android:configChanges="orientation|keyboardHidden|keyboard|navigation"
            android:label="@string/app_name"
            android:launchMode="singleTask"
            android:hardwareAccelerated="true"
            android:theme="@style/TranslucentTheme"
            android:screenOrientation="user"
            android:windowSoftInputMode="adjustResize" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

<activity

android:name="cn.com.sway.app.MainActivity"

android:configChanges="orientation|keyboardHidden|keyboard|navigation"

android:label="@string/app_name"

android:launchMode="singleTask"

android:hardwareAccelerated="true"

android:theme="@style/TranslucentTheme"

android:screenOrientation="user"

android:windowSoftInputMode="adjustResize" >

<intent-filter>

</intent-filter>

</activity>

其他：在前端与MainActivity进行交互

前端这么写：

var main = plus.android.runtimeMainActivity();//获取当前的Activity
var res = main.getResData();//直接调用自定义Activity中的getResData方法
console.log(res);

var main = plus.android.runtimeMainActivity();//获取当前的Activity

var res = main.getResData();//直接调用自定义Activity中的getResData方法

console.log(res);

在MainActivity补充getResData方法：

public String getResData(){
    return data;
}

public String getResData(){

return data;

}

Javascript：Json对象与Json字符串的转化

1.jQuery插件支持的转换方式：

$.parseJSON( jsonstr ); //jQuery.parseJSON(jsonstr),可以将json字符串转换成json对象

2.浏览器支持的转换方式(Firefox，chrome，opera，safari，ie9，ie8)等浏览器：

JSON.stringify(obj)将JSON转为字符串。JSON.parse(string)将字符串转为JSON格式；

var a={“name”:”tom”,”sex”:”男”,”age”:”24″};
var b='{“name”:”Mike”,”sex”:”女”,”age”:”29″}';
var aToStr=JSON.stringify(a);
var bToObj=JSON.parse(b);
alert(typeof(aToStr)); //string
alert(typeof(bToObj));//object

3.Javascript支持的转换方式：
eval(‘(‘ + jsonstr + ‘)’); //可以将json字符串转换成json对象,注意需要在json字符外包裹一对小括号
注：ie8(兼容模式),ie7和ie6也可以使用eval()将字符串转为JSON对象，但不推荐这些方式，这种方式不安全eval会执行json串中的表达式。

4.JSON官方的转换方式：
http://www.json.org/提供了一个json.js,这样ie8(兼容模式),ie7和ie6就可以支持JSON对象以及其stringify()和parse()方法；
可以在https://github.com/douglascrockford/JSON-js上获取到这个js，一般现在用json2.js。

uni-app离线android打包使用scheme

hbuilder版本：3.1.12

在AndroidManifest.xml中对io.dcloud.PandoraEntry添加scheme内容（注意不是io.dcloud.PandoraEntryActivity）

        <activity
            <span style="color: #ff0000;">android:name="io.dcloud.PandoraEntry"</span>
            android:configChanges="orientation|keyboardHidden|keyboard|navigation"
            android:label="@string/app_name"
            android:launchMode="singleTask"
            android:hardwareAccelerated="true"
            android:theme="@style/TranslucentTheme"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustResize" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
<span style="color: #ff0000;">            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="xxxxx" />
            </intent-filter></span>
            <intent-filter>
                <action android:name="android.intent.action.oppopush" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

<activity

<span style="color: #ff0000;">android:name="io.dcloud.PandoraEntry"</span>

android:configChanges="orientation|keyboardHidden|keyboard|navigation"

android:label="@string/app_name"

android:launchMode="singleTask"

android:hardwareAccelerated="true"

android:theme="@style/TranslucentTheme"

android:screenOrientation="portrait"

android:windowSoftInputMode="adjustResize" >

<intent-filter>

</intent-filter>

</intent-filter></span>

<intent-filter>

</intent-filter>

</activity>

记得把scheme换成正确的。
