Add a dio-http-cache interceptor in Dio : 23 | 24 | ```dart 25 | dio.interceptors.add(DioCacheManager(CacheConfig(baseUrl: "http://www.google.com")).interceptor); 26 | ``` 27 | 28 | 2. Set maxAge for a request : 29 | 30 | ```dart 31 | Dio().get( 32 | "http://www.google.com", 33 | options: buildCacheOptions(Duration(days: 7)), 34 | ); 35 | ``` 36 | 37 | ### The advanced 38 | 39 | 1. **Custom your config by buildCacheOptions :** 40 | 41 | 1. **primaryKey:** By default, `host + path` is used as the primaryKey, and you can also customize it. 42 | 43 | 2. **subKey:** By default, query ( data or queryParameters) is used as subKey, and you can specify the subKey when it's necessary, for example: 44 | 45 | ```dart 46 | buildCacheOptions(Duration(days: 7), subKey: "page=1") 47 | ``` 48 | 49 | 3. **maxAge:** set the cache time. If the value is null or not setted, it will try to get maxAge and maxStale from response headers. 50 | 51 | 4. **maxStale:** set stale time. When an error (like 500,404) occurs before maxStale, try to return cache. 52 | 53 | ```dart 54 | buildCacheOptions(Duration(days: 7), maxStale: Duration(days: 10)) 55 | ``` 56 | 57 | 5. **forceRefresh**: false default. 58 | 59 | ```dart 60 | buildCacheOptions(Duration(days: 7), forceRefresh: true) 61 | ``` 62 | 63 | 1. Get data from network first. 64 | 2. If getting data from network succeeds, store or refresh cache. 65 | 3. If getting data from network fails or no network avaliable, **try** get data from cache instead of an error. 66 | 67 | 2. **Use "CacheConfig" to config default params** 68 | 69 | 1. **baseUrl:** it’s optional; If you don't have set baseUrl in CacheConfig, when you call `deleteCache`, you need provide full path like `"https://www.google.com/search?q=hello"`, but not just `"search?q=hello"`. 70 | 2. **encrypt / decrypt:** these two must be used together to encrypt the disk cache data, you can also zip data here. 71 | 3. **defaultMaxAge:** use `Duration(day:7)` as default. 72 | 4. **defaultaMaxStale:** similar with DefaultMaxAge. 73 | 5. **databasePath:** database path. 74 | 6. **databaseName:** database name. 75 | 7. **skipMemoryCache:** false defalut. 76 | 8. **skipDiskCache:** false default. 77 | 9. **maxMemoryCacheCount:** 100 defalut. 78 | 10. **defaultRequestMethod**: use "POST" as default, it will be used in `delete caches`. 79 | 11. **diskStore**: custom disk storage. 80 | 81 | 3. **How to clear expired cache** 82 | 83 | * Just ignore it, that is automatic. 84 | 85 | * But if you insist : `DioCacheManager.clearExpired();` 86 | 87 | 4. **How to delete caches** 88 | 89 | 1. No matter what subKey is, delete local cache if primary matched. 90 | 91 | ```dart 92 | // Automatically parses primarykey from path 93 | _dioCacheManager.deleteByPrimaryKey(path, requestMethod: "POST"); 94 | ``` 95 | 96 | 2. Delete local cache when both primaryKey and subKey matched. 97 | 98 | ```dart 99 | // delete local cache when both primaryKey and subKey matched. 100 | _dioCacheManager.deleteByPrimaryKeyAndSubKey(path, requestMethod: "GET"); 101 | ``` 102 | 103 | **INPORTANT:** If you have additional parameters when requesting the http interface, you must take them with it, for example: 104 | 105 | ```dart 106 | _dio.get(_url, queryParameters: {'k': keyword}, 107 | options: buildCacheOptions(Duration(hours: 1))) 108 | //delete the cache: 109 | _dioCacheManager.deleteByPrimaryKeyAndSubKey(_url, requestMethod: "GET", queryParameters:{'k': keyword}); 110 | ``` 111 | 112 | ```dart 113 | _dio.post(_url, data: {'k': keyword}, 114 | options: buildCacheOptions(Duration(hours: 1))) 115 | //delete the cache: 116 | _dioCacheManager.deleteByPrimaryKeyAndSubKey(_url, requestMethod: "POST", data:{'k': keyword}); 117 | ``` 118 | 119 | 3. Delete local cache by primaryKey and optional subKey if you know your primarykey and subkey exactly. 120 | 121 | ```dart 122 | // delete local cache by primaryKey and optional subKey 123 | _dioCacheManager.delete(primaryKey,{subKey,requestMethod}); 124 | ``` 125 | 126 | 5. **How to clear All caches** (expired or not) 127 | 128 | ```dart 129 | _dioCacheManager.clearAll(); 130 | ``` 131 | 132 | 6. **How to know if the data come from Cache** 133 | 134 | ```dart 135 | if (null != response.headers.value(DIO_CACHE_HEADER_KEY_DATA_SOURCE)) { 136 | // data come from cache 137 | } else { 138 | // data come from net 139 | } 140 | ``` 141 | 142 | 143 | ### Example for maxAge and maxStale 144 | 145 | ```dart 146 | _dio.post( 147 | "https://www.exmaple.com", 148 | data: {'k': "keyword"}, 149 | options:buildCacheOptions( 150 | Duration(days: 3), 151 | maxStale: Duration(days: 7), 152 | ) 153 | ) 154 | ``` 155 | 156 | 1. 0 ~ 3 days : Return data from cache directly (irrelevant with network). 157 | 2. 3 ~ 7 days: 158 | 1. Get data from network first. 159 | 2. If getting data from network succeeds, refresh cache. 160 | 3. If getting data from network fails or no network avaliable, **try** get data from cache instead of an error. 161 | 3. 7 ~ ∞ days: It won't use cache anymore, and the cache will be deleted at the right time. 162 | 163 | ### License 164 | 165 | ``` 166 | Copyright 2019 Hurshi 167 | 168 | Licensed under the Apache License, Version 2.0 (the "License"); 169 | you may not use this file except in compliance with the License. 170 | You may obtain a copy of the License at 171 | 172 | http://www.apache.org/licenses/LICENSE-2.0 173 | 174 | Unless required by applicable law or agreed to in writing, software 175 | distributed under the License is distributed on an "AS IS" BASIS, 176 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 177 | See the License for the specific language governing permissions and 178 | limitations under the License. 179 | ``` 180 | -------------------------------------------------------------------------------- /README_zh.md: -------------------------------------------------------------------------------- 1 | [![Pub](https://img.shields.io/pub/v/dio_http_cache.svg?style=flat)](https://pub.dev/packages/dio_http_cache) 2 | 3 | ### 简介 4 | 5 | * Dio-http-cache 是 Flutter 的 http 缓存库，为 [Dio](https://github.com/flutterchina/dio) 设计，就像 Android 中的 [RxCache](https://github.com/VictorAlbertos/RxCache) 一样。 6 | * Dio-http-cache 使用 [sqflite](https://github.com/tekartik/sqflite) 作为磁盘缓存，使用 [Google/quiver-dart 的LRU算法](https://github.com/google/quiver-dart) 作为内存缓存策略。 7 | * 有参考 [flutter_cache_manager](https://github.com/renefloor/flutter_cache_manager) 开发，为此感谢。 8 | * **更详细**且**最新**的文档还请参阅 [README](https://github.com/hurshi/dio-http-cache)。 9 | 10 | ### 添加依赖 11 | 12 | ```yaml 13 | dependencies: 14 | dio_http_cache: ^0.3.x #latest version 15 | ``` 16 | 17 | ### 简单使用 18 | 19 | 1. 为 dio 添加拦截器： 20 | 21 | ```dart 22 | dio.interceptors.add(DioCacheManager(CacheConfig(baseUrl: "http://www.google.com")).interceptor); 23 | ``` 24 | 25 | 2. 为需要缓存的请求添加 options: 26 | 27 | ```dart 28 | Dio().get( 29 | "http://www.google.com", 30 | options: buildCacheOptions(Duration(days: 7)), 31 | ); 32 | ``` 33 | 34 | ### 进阶使用 35 | 36 | 1. **buildCacheOptions可以配置多种参数满足不同的缓存需求：** 37 | 1. ***MaxAge:*** 只有这个是必须的参数，设置缓存的时间； 38 | 39 | 2. ***MaxStale:*** 设置过期时常；在maxAge过期，而请求网络**失败**的时候，如果maxStale没有过期，则会使用这个缓存数据。 40 | 41 | ```dart 42 | buildCacheOptions(Duration(days: 7), maxStale: Duration(days: 10)) 43 | ``` 44 | 45 | 3. ***subKey:*** dio-http-cache 默认使用 url 作为缓存 key ,但当 url 不够用的时候，比如 post 请求分页数据的时候，就需要配合subKey使用。 46 | 47 | ```dart 48 | buildCacheOptions(Duration(days: 7), subKey: "page=1") 49 | ``` 50 | 51 | 2. **CacheConfig 可以配置一些默认参数：** 52 | 1. ***encrypt / dectrypt:*** 这2个必须组合使用，实现磁盘缓存数据的加密。也可以在这里实现数据的压缩。 53 | 2. ***DefaultMaxAge:*** 默认值为 Duration( day: 7 ), 在上面 buildCacheOption 中如果没有配置 MaxAge 有错误，或者自己实现了 option 而没有配置 MaxAge, 会使用这个默认值； 54 | 3. ***DefalutMaxStale:*** 和 DefaultMaxAge 类似； 55 | 4. ***DatabaseName:*** 配置数据库名； 56 | 5. ***SkipMemoryCache:*** 默认 false； 57 | 6. ***SkipDiskCache:*** 默认 false; 58 | 7. ***MaxMemoryCacheCount:*** 最大的内存缓存数量，默认100； 59 | 60 | 3. **如何清理已过期缓存** 61 | 62 | * 会自动清理不用管 63 | * 如果非要清理，可以调用：`DioCacheManager.clearExpired();` 64 | 65 | 4. **如何删除一条记录** 66 | 67 | ``` 68 | _dioCacheManager.delete(url);//会删除所有 url 的缓存。 69 | _dioCacheManager.delete(url,subKey); 70 | ``` 71 | 72 | 5. **如何清理所有缓存**（不管有没有过期） 73 | 74 | ``` 75 | _dioCacheManager.clearAll(); 76 | ``` 77 | 78 | ### License 79 | 80 | ``` 81 | Copyright 2019 Hurshi 82 | 83 | Licensed under the Apache License, Version 2.0 (the "License"); 84 | you may not use this file except in compliance with the License. 85 | You may obtain a copy of the License at 86 | 87 | http://www.apache.org/licenses/LICENSE-2.0 88 | 89 | Unless required by applicable law or agreed to in writing, software 90 | distributed under the License is distributed on an "AS IS" BASIS, 91 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 92 | See the License for the specific language governing permissions and 93 | limitations under the License. 94 | ``` 95 | -------------------------------------------------------------------------------- /android/app/src/main/java/io/flutter/plugins/GeneratedPluginRegistrant.java: -------------------------------------------------------------------------------- 1 | package io.flutter.plugins; 2 | 3 | import io.flutter.plugin.common.PluginRegistry; 4 | 5 | /** 6 | * Generated file.
