laravel升级记录，laravel from 5.2 upgrade 5.3

升级之前我们要知道的第一个点，在5.3中被移除的方法如下，详情点击这里

• 1 - Illuminate\Contracts\Bus\SelfHandling contract. Can be removed from jobs.
• 2 - The lists method on the Collection, query builder and Eloquent query builder objects has been renamed to pluck. The method signature remains the same.
• 3 - Implicit controller routes using Route::controller have been deprecated. Please use explicit route registration in your routes file. This will likely be extracted into a package.
• 4 - The get, post, and other route helper functions have been removed. You may use the Route facade instead.
• 5 - The database session driver from 5.1 has been renamed to legacy-database and will be removed. Consult notes on the "database session driver" above for more information.
• 6 - The Str::randomBytes function has been deprecated in favor of the random_bytes native PHP function.
• 7 - The Str::equals function has been deprecated in favor of the hash_equals native PHP function.
• 8 - Illuminate\View\Expression has been deprecated in favor of Illuminate\Support\HtmlString.
• The WincacheStore cache driver has been removed.

如果是在国内的话，记得更新镜像源，请参考这里

然后修改composer.json中

"laravel/framework": "5.2.*",

改为

"laravel/framework": "5.3.*",

然后执行

composer update --verbose

或者

composer update --verbose --ignore-platform-reqs

如果遇到依赖问题，比如我这里遇到了laravelcollective/html，

类似requires...satisfiable...的提示

只需要将这个库暂时移除，然后在执行上面的命令

顺利的话，就安装成功了

然后在安装回刚刚移除的库，比如laravelcollective/html，这个时候可能会遇到，如果使用原来老的版本的话，会提示类似不兼容现在laravel5.3这个版本，需要针对性的安装对应的版本，如果不带版本号的话会安装最新版本，那个时候，依赖的项目会很多，composer会自动升级对应的依赖版本，建议不要这么做

最后安装完，参考[这里]，修改对应的代码就可以了。
