Guzzle 3.x 如何设置内容类型：application/json？

Question

我使用的是旧的 php 版本，所以我无法在当前服务器上更新 guzzle。有办法吗set Content-Type :application/json？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/1.1Content-Length:    88Content-Type:      application/x-www-form-urlencoded; charset=utf-8Headers:           A7t1xXXXXXXXr23vt8jL999Host:              my_api.url.comUser-Agent:        Guzzle/3.9.3 curl/7.19.7 PHP/5.6.30X-Amzn-Trace-Id:   Root=1-5ec66539-XXXXXXXXX9c3c667a3aX-Forwarded-For:   118.XXXX.242X-Forwarded-Port:  443X-Forwarded-Proto: httpsjson%5Bname%5D=article%2Fartem%2Ftest77.jpg&json%5Bimage%5D=eHh4&json%5Benv%5D=localhost我想得到这样的回应：POST /api/image/xxx HTTP/1.1Content-Length:    70Content-Type:      application/jsonHost:              my_api.url.comUser-Agent:        A7t1xXXXXXXXr23vt8jL999X-Amzn-Trace-Id:   Root=1-5ec66539-XXXXXXXXX9c3c667a3aX-Forwarded-For:   118.XXXX.242X-Forwarded-Port:  443X-Forwarded-Proto: https{"name":"article\/artem\/test77.jpg","image":"eHh4","env":"localhost"}

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();
