Guzzle 3.x 如何设置内容类型：application/json？

Question

我使用的是旧 php 版本，所以我无法在当前服务器上更新 guzzle。

有办法set Content-Type :application/json吗？

我在本地机器上使用的代码（我尝试了不同的方法来设置 Content-Type - 它被注释掉了）：

    $client = new \Guzzle\Http\Client();
    $request = $client->post($cms_admin_api_url,
        ['headers' => [
            'user-agent' => $admin_token,
            //'Content-Type' => 'application/json',
            //'Accept' => 'application/json'
        ],
        //'Content-Type' => 'application/json'
        ],
        ['json'        => [
            'name' => $key,
            'image' => base64_encode($body),
            'env' => $cake_emv
        ]
        ]);
        $response = $request->send();

我收到这样的回复：

POST /api/image/xxx HTTP/1.1
Content-Length:    88
Content-Type:      application/x-www-form-urlencoded; charset=utf-8

我想得到这样的回应：

POST /api/image/xxx HTTP/1.1
Content-Length:    70
Content-Type:      application/json
Host:              my_api.url.com

Answer 1

setBody() 成功了：

$client = new \Guzzle\Http\Client();

$client->setUserAgent($admin_token);

$request = $client->post($cms_admin_api_url);

$request->setBody(json_encode([
    'name'  => $key,
    'image' => base64_encode($data)
]), 'application/json');

$response = $request->send();
