Guzzle是一个PHP HTTP客户端，可以轻松发送HTTP请求，并且可以轻松集成Web服务。
1.使用composer安装
composer require guzzlehttp/guzzle
2.或者编辑项目的composer.json文件，添加Guzzle作为依赖
计算
安全
数据库
网络和加速
企业服务
{
"require": {
"guzzlehttp/guzzle": "~6.0"
}
}执行 composer update
1.发送请求
use GuzzleHttp\Client;
$client = new Client([
// Base URI is used with relative requests
'base_uri' => 'http://httpbin.org',
// You can set any number of default request options.
'timeout' => 2.0,
]);
$response = $client->get('http://httpbin.org/get');
$response = $client->delete('http://httpbin.org/delete');
$response = $client->head('http://httpbin.org/get');
$response = $client->options('http://httpbin.org/get');
$response = $client->patch('http://httpbin.org/patch');
$response = $client->post('http://httpbin.org/post');
$response = $client->put('http://httpbin.org/put');2.设置查询字符串
$response = $client->request('GET', 'http://httpbin.org?foo=bar');或使用 query 请求参数来声明查询字符串参数：
$client->request('GET', 'http://httpbin.org', [
'query' => ['foo' => 'bar']
]);3.设置POST表单，传入 form_params 数组参数
$response = $client->request('POST', 'http://httpbin.org/post', [
'form_params' => [
'field_name' => 'abc',
'other_field' => '123',
'nested_field' => [
'nested' => 'hello'
]
]
]);4.使用响应
# 状态码
$code = $response->getStatusCode(); // 200
$reason = $response->getReasonPhrase(); // OK
# header
// Check if a header exists.
if ($response->hasHeader('Content-Length')) {
echo "It exists";
}
// Get a header from the response.
echo $response->getHeader('Content-Length');
// Get all of the response headers.
foreach ($response->getHeaders() as $name => $values) {
echo $name . ': ' . implode(', ', $values) . "\r\n";
}
# 响应体
$body = $response->getBody();
// Implicitly cast the body to a string and echo it
echo $body;
// Explicitly cast the body to a string
$stringBody = (string) $body;
// Read 10 bytes from the body
$tenBytes = $body->read(10);
// Read the remaining contents of the body as a string
$remainingBytes = $body->getContents();composer方式安装
composer global require "phpunit/phpunit=5.5.*"或者在composer.json文件中声明对phpunit/phpunit的依赖
{
"require-dev": {
"phpunit/phpunit": "5.5.*"
}
}1.我们在tests\unit\MyApiTest.php中定义了两个测试用例
<?php
class MyApiTest extends \PHPUnit_Framework_TestCase
{
protected $client;
public function setUp()
{
$this->client = new \GuzzleHttp\Client( [
'base_uri' => 'http://myhost.com',
'http_errors' => false, #设置成 false 来禁用HTTP协议抛出的异常(如 4xx 和 5xx 响应)，默认情况下HTPP协议出错时会抛出异常。
]);
}
public function testAction1()
{
$response = $this->client->get('/api/v1/action1');
$body = $response->getBody();
//添加测试
$this->assertEquals(200, $response->getStatusCode());
$data = json_decode($body, true);
$this->assertArrayHasKey('errorno', $data);
$this->assertArrayHasKey('errormsg', $data);
$this->assertArrayHasKey('data', $data);
$this->assertEquals(0, $data['errorno']);
$this->assertInternalType('array', $data['data']);
}
public function testAction2()
{
$response = $this->client->post('/api/v1/action2', [
'form_params' => [
'name' => 'myname',
'age' => 20,
],
]);
$body = $response->getBody();
//添加测试
$this->assertEquals(200, $response->getStatusCode());
$data = json_decode($body, true);
$this->assertArrayHasKey('errorno', $data);
$this->assertArrayHasKey('errormsg', $data);
$this->assertArrayHasKey('data', $data);
$this->assertEquals(0, $data['errorno']);
$this->assertInternalType('array', $data['data']);
}
}2.运行测试
在项目根目录执行命令
php vendor/bin/phpunit tests/unit/MyApiTest.php
