缺少参数

Question

我在使用GuzzleHttp在POST请求中传递版本参数时遇到问题。

客户端错误：GET https://gateway.watsonplatform.net/tone-analyzer/api/v3/tone导致错误响应：{“400 Bad Request”：400，"sub_code":"C00005"，“error”：“URL中缺少次要版本参数。若要使用最新版本，请添加th (截断...)

这是我最近尝试过的：

    $client = new \GuzzleHttp\Client([
        'base_uri' => 'https://gateway.watsonplatform.net/'
    ]);
    $toneAnalyserResponse = $client->request('POST', 'tone-analyzer/api/v3/tone', [
        'auth' => ['{username}', '{password}'],
        'headers' => [
            'Content-Type' => 'text/plain',
        ],
        'form_params' => [
            'version' => '2017-09-21',
            'tone_input' => $text,
            'sentences' => true
        ]
    ]);

这也失败了：

$client = new \GuzzleHttp\Client([
    'base_uri' => 'https://gateway.watsonplatform.net/'
]);
$toneAnalyserResponse = $client->request('POST', 'tone-analyzer/api/v3/tone', [
    'auth' => ['{username}', '{password}'],
    'headers' => [
        'Content-Type' => 'text/plain',
    ],
    'version' => '2017-09-21',
    'tone_input' => $text,
    'sentences' => true
]);

如果使用GET而不是POST，也会失败。

如果我更改URI并添加版本，那么它可以正常工作(好吧，它失败了，因为它在请求中没有要分析的文本)：

更改:音调分析器/api/v3/tone

致:音调分析器/api/v3/tone?版本=2017-09-21

所以，我猜问题是如何使用GuzzleHttp在请求中传递URL参数？

注意:我的CURL命令工作正常(http 200)：

curl -X POST -u "{username}":"{password}" --header 'Content-Type: text/plain' --header 'Accept: application/json' --header 'Content-Language: en' --header 'Accept-Language: en' -d 'I hate these new features On #ThisPhone after the update.\r\n \ 
     I hate #ThisPhoneCompany products, you%27d have to torture me to get me to use #ThisPhone.\r\n \ 
     The emojis in #ThisPhone are stupid.\r\n \ 
     #ThisPhone is a useless, stupid waste of money.\r\n \ 
     #ThisPhone is the worst phone I%27ve ever had - ever .\r\n \ 
     #ThisPhone another ripoff, lost all respect SHAME.\r\n \ 
     I%27m worried my #ThisPhone is going to overheat like my brother%27s did.\r\n \ 
     #ThisPhoneCompany really let me down... my new phone won%27t even turn on.' 'https://gateway.watsonplatform.net/tone-analyzer/api/v3/tone?version=2017-09-21&sentences=true'

需要发送querystring的query参数。请检查以下代码：

$toneAnalyserResponse = $client->request('POST', 'tone-analyzer/api/v3/tone', [
    'auth' => ['{username}', '{password}'],
    'headers' => [
        'Content-Type' => 'text/plain',
    ],
    'query' => [
       'version' => '2017-09-21'
    ]
]);
