How to build API Services in ThinkPHP

This article will explain in detail how to build API services in ThinkPHP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1 download Composer

Composer is a tool that PHP uses to manage dependency relationships.

1.1 windows version

Download address: getcomposer.org/

If an error is reported:

Program Output: PHP Deprecated: Directive 'track_errors' is deprecated in Unknown on line 0

Then modify php.ini:

; track_errors = On (On changed to Off) track_errors = Off

After restarting the HTTP service, the installation passed.

1.2 macOS version

Execute:

Curl-sS https://getcomposer.org/installer | php

If you report the following information incorrectly, or if you can't finish downloading it:

Failed to decode zlib stream

Just go directly to getcomposer.org/download/ to download the latest version of composer.phar.

After downloading, execute it in the directory where composer.phar is stored:

Mv composer.phar / usr/local/bin/composer

Then you can use composer globally, and execute the following command to check the version number:

Composer-v

2 install / upgrade ThinkPHP6

Execute the following command to switch to Aliyun image to accelerate download:

Composer config-g repo.packagist composer https://mirrors.aliyun.com/composer/

Select the directory and execute:

Composer create-project topthink/think projectName

After installation, enter the project directory and execute:

Php think run

Browser access:

Http://localhost:8000/

If the port is changed, execute:

Php think run-p 80

Upgrade ThinkPHP6, enter the project root directory, and execute:

Composer update

In the actual deployment, you should bind the domain name to access the public directory and make sure that other directories are not under the WEB directory.

3 configure debug mode

Rename .example.env to .env in the root directory and set the following code:

APP_DEBUG = true

4 Multi-application deployment

Directory structure

/ www WEB deployment directory (or subdirectory) ├─ / app application directory │ ├─ / myApp subapplication directory │ │ ├─ common.php subapplication function file │ │ ├─ / controller subapplication controller directory │ │ ├─ Index.php subapplication controller │ │ ├─ / model Subapplication model directory │ │ ├─ / view subapplication view directory │ │ ├─ / config subapplication configuration directory │ │ ├─ / route subapplication routing directory │ │ └─. Sub-application more class library directory │ │ | ├─ BaseController.php default basic controller class │ ├─ common.php common function file │ ├─ event.php event definition file | ├─ ExceptionHandle.php application exception definition file (be sure to keep this! Otherwise ERROR 500) | | ─ middleware.php global middleware definition file │ ├─ provider.php service provides definition file | └─ Request.php application request object (be sure to keep this! Otherwise ERROR 500)

Multi-application mode extension think-multi-app

To use multi-application mode, you need to install think-multi-app, which is installed by executing the following command from the project root:

Composer require topthink/think-multi-app

Modify the path of the controller

Open app/myApp/controller/Index.php and adjust namespace

-namespace app\ controller; + namespace app\ myApp\ controller; use app\ BaseController

It can then be accessed through the http service:

Http://127.0.0.1/thinkphp6/public/index.php/myApp

URL rewriting

If you want to omit index.php, you can access the

Http://127.0.0.1/thinkphp6/public/myApp

Add to public/.htaccess:

Options + FollowSymlinks-Multiviews RewriteEngine On RewriteCond% {REQUEST_FILENAME}!-d RewriteCond% {REQUEST_FILENAME}!-f RewriteRule ^ (. *) $index.php/$1 [QSA,PT,L]

URL rewriting has been completed through the official default installation of composer. Here is a memo only.

5 multi-stage controller

The directory structure is as follows:

├─ / app application directory │ ├─ / myApp subapplication directory │ │ ├─ / controller subapplication controller directory │ │ ├─ / api secondary controller directory │ │ ├─ / Login.php secondary controller

Login.php Code:
