Question

我正在尝试使用Guzzle消耗RESTful API。阅读Guzzle documentation，我调用get和post等方法来配置请求，然后send实际运行HTTP请求。

$request = $client->post('http://httpbin.org/post', array(), array(
    'custom_field' => 'my custom value',
    'file_field'   => '@/path/to/file.xml'
));

$response = $request->send();

但是在我的情况下，似乎在没有字段的post调用期间发送了HTTP请求。这是我的代码

define('CUST_ID', 'blahblah');
define('API_KEY', 'verysecure');

// Construct the underlying Guzzle client
$oClient = new \GuzzleHttp\Client(
    ['base_url' =>
    ['http://api.postmates.com/{version}/', ['version' => 'v1']],
    'defaults' => [
        // HTTP Basic auth header, username is api key, password is blank
        'auth'    => [API_KEY, ''],
    ]]);
$oRq = $oClient->post(
    "customers/" . CUST_ID . "/delivery_quotes",
    [], 
    ['pickup_address'  => '232 E Manhattan Ave, Denver, CO 80203',
     'dropoff_address' => '4400 Midwest St, Denver, CO 80205']);

虽然发出请求（没有POST参数）

POST /v1/customers/blahblah/delivery_quotes HTTP/1.1
Host: api.postmates.com
Authorization: Basic verysecure==
User-Agent: Guzzle/5.2.0 curl/7.37.1 PHP/5.6.0
Content-Length: 0

和回复

HTTP/1.1 400 BAD REQUEST
Content-Type: application/json
Date: Fri, 13 Feb 2015 07:32:16 GMT
Server: nginx/1.1.19
Content-Length: 205
Connection: keep-alive

{"kind": "error", "code": "invalid_params", "params": {"dropoff_address": "This field is required.", "pickup_address": "This field is required."}, "message": "The parameters of your request were invalid."}

所以看起来我正在验证，但没有传递任何帖子参数。我尝试使用setPostField方法设置POST字段没有运气。正如我所说，在这种情况下，似乎在调用setPostField之前发送了HTTP请求，在任何一种情况下都会在我调用send之前发送HTTP请求。

我已经尝试过guzzlehttp / guzzle 5.2.0和5.0.0。

哇，看起来我正在查看2个文档，一个用于the newer GuzzleHttp\Client，一个用于the older Guzzle\Http\Client。如果要延迟调用HTTP请求，则需要调用createRequest与新库的最大区别。

新图书馆下的工作代码

define('CUST_ID', 'blahblah');
define('API_KEY', 'verysecure');

// Construct the underlying Guzzle client
$oClient = new GuzzleHttp\Client(
    ['base_url' =>
    ['http://api.postmates.com/{version}/', ['version' => 'v1']],
    'defaults' => [
        // HTTP Basic auth header, username is api key, password is blank
        'auth'    => [API_KEY, ''],
    ]]);

// Create the request
$oRq = $oClient->createRequest(
    'POST',
    "customers/" . CUST_ID . "/delivery_quotes",
    [ 'body' =>
        ['pickup_address'  => '232 E Manhattan Ave, Denver, CO 80203',
         'dropoff_address' => '4400 Midwest St, Denver, CO 80205']]);

// Send the request
$oRsp = $oClient->send($oRq);

guzzlehttp / guzzle在发送之前发送HTTP请求 - ＆gt; send（）
