Installation

Issue following command in console:

composer require imphinite/gaode-maps

Alternatively edit composer.json by adding following line and run composer update

"require": { 
		....,
		"imphinite/gaode-maps",
	
	},

Configuration

Register package service provider and facade in 'config/app.php'

'providers' => [
    ...
    'GaodeMaps\ServiceProvider\GaodeMapsServiceProvider',
]

'aliases' => [
    ...
    'GaodeMaps' => 'GaodeMaps\Facade\GaodeMapsFacade',
]

Publish configuration file using php artisan vendor:publish --tag=gaodemaps --force or simply copy package configuration file and paste into config/gaodemaps.php

Open configuration file config/gaodemaps.php and add your service key

    /*
    |----------------------------------
    | Service Keys
    |------------------------------------
    */
    
    'key'       => 'YOUR GAODE API KEY HERE',

If you like to use different keys for any of the services, you can overwrite master API Key by specifying it in the service array for selected web service.

Usage

Here is an example of making request to Places Search API:

$service = GaodeMaps::load('nearbysearch')
        ->setParam([
            'location'          => '120.392164,36.056936',  // Longitude first in Chinese convention 
            'keywords'          => '餐厅',
            'radius'            => 5000,
            'page'              => 1,
            'extensions'        => 'all',
            'output'            => 'json'
        ]);
$response = $service->get();
...

Alternatively parameters can be set using setParamByKey() method. For deeply nested array use "dot" notation as per example below.

$endpoint = GaodeMaps::load('nearbysearch')
        ->setParamByKey('location', '120.392164,36.056936')
        ->setParamByKey('keywords', '餐厅') //return $this
...

Another example showing request to Batch Request service when requesting multiple places' details:

$batch_urls = array();
array_push($batch_urls, (object) array(
    'url' => GaodeMaps::load('placedetails')
        ->setParam(['id' => $place->id)
        ->getBatchUrl()
    )
);

$service = GaodeMaps::load('batchrequest')
        ->setParam([
            'ops'               => $batch_urls
        ]);
$response = $batch_service->get();
...

Available methods

• load( $serviceName )
• setParamByKey( $key, $value )
• setParam( $parameters )
• getBatchUrl()
• get()

load( $serviceName ) - load web service by name

Accepts string as parameter, web service name as specified in configuration file.
Returns reference to it's self.

GaodeMaps::load('nearbysearch') 
... 

setParamByKey( $key, $value ) - set request parameter using key:value pair

Accepts two parameters:

• key - body parameter name
• value - body parameter value

Deeply nested array can use 'dot' notation to assign value.
Returns reference to it's self.

$service = GaodeMaps::load('nearbysearch')
        ->setParamByKey('location', '120.392164,36.056936')
        ->setParamByKey('keywords', '餐厅') //return $this
...

setParam( $parameters ) - set all request parameters at once

Accepts array of parameters
Returns reference to it's self.

$service = GaodeMaps::load('nearbysearch')
        ->setParam([
            'location'          => '120.392164,36.056936',  // Longitude first in Chinese convension 
            'keywords'          => '餐厅',
            'radius'            => 5000,
            'page'              => 1,
            'extensions'        => 'all',
            'output'            => 'json'
        ]); // return $this
...

getBatchUrl() - generate a Url of this service for Batch Request web service

Returns Batch Request url of this service.

$url = GaodeMaps::load('nearbysearch')
    ->setParam([
        'location'          => '120.392164,36.056936',  // Longitude first in Chinese convension 
        'keywords'          => '餐厅',
        'radius'            => 5000,
        'page'              => 1,
        'extensions'        => 'all',
        'output'            => 'json'
    ])->getBatchUrl();
...

• get() - perform web service request (irrespectively to request type POST or GET )

Returns web service response in the format specified by setEndpoint() method, if omitted defaulted to JSON. Use json_decode() to convert JSON string into PHP variable. See Processing Response for more details on parsing returning output.

$response = GaodeMaps::load('nearbysearch')
        ->setParam([
            'location'          => '120.392164,36.056936',  // Longitude first in Chinese convension 
            'keywords'          => '餐厅',
            'radius'            => 5000,
            'page'              => 1,
            'extensions'        => 'all',
            'output'            => 'json'
        ])->get();

var_dump(json_decode($response));  // output 
...
