Guzzle 使用嵌套数组发布多部分请求

【中文标题】Guzzle 使用嵌套数组发布多部分请求【英文标题】:Guzzle post multipart request with nested array 【发布时间】:2017-05-26 00:33:11 【问题描述】:

经过一整天的调试和反复尝试,尝试使用带有嵌套数组和资源项的 Guzzle6 帖子寻找一个好的方法。

我在 Guzzle6 文档中发现需要使用 ['multipart' => []] 发布数据。当我得到单个数组项时,这有效。但是我得到了这样的嵌套数组项。

[
    [firstname] => 'Danny',
    [phone] => [
        [0] => [
            [phone] => 0612345678
        ]
    ]
    [picture] => '/data/...'
]

这需要为 Guzzle6 的多部分格式,如下所示。

[
    [
        'name' => 'firstname',
        'contents' => 'Danny'
    ],
    [
        'name' => 'phone[0][phone]
        'contents' => '0612345678'
    ],
    [
        'name' => 'picture',
        'contents' => fopen('....', 'r')
    ]
]

我想在没有特殊技巧的情况下解决这个问题。有没有一种好方法可以将带有嵌套数组和资源的后数组发送到多部分数组。

【问题讨论】:

所以你基本上想要创建一个循环来迭代每个键并以多部分格式创建一个新数组 【参考方案1】:

是的,有一个更简单的方法。您可以将值作为所需格式的数组发送并使用http_build_query 组合它们。

例子:

$params = [
    'firstname' => 'Danny',
    'phone' => [
            'phone' => '0612345678'
               ]
    'picture' => '/data/...'
]


$request_pararms = http_build_query($params);

现在在 Guzzle 中发送 $request_params

【讨论】:

此方法无效。我需要发布具有多部分内容类型的图像。当值包含 fopen() 值时,您的答案会删除图片。 构建查询参数,如果是这种情况,然后附加图像。 如何将文件附加到 guzzle post 请求中,文档中没有可用的附加功能。【参考方案2】:

经过一整天的工作,我得到了我的多部分表单数据数组。对于每个有同样问题的人,这里是代码。在 $output 中有一个数据中的字段数组。它可以在 ['multipart' => $output] 中与 Guzzle 一起使用。

    $output = [];

    foreach($data as $key => $value)
        if(!is_array($value))
            $output[] = ['name' => $key, 'contents' => $value];
            continue;
        

        foreach($value as $multiKey => $multiValue)
            $multiName = $key . '[' .$multiKey . ']' . (is_array($multiValue) ? '[' . key($multiValue) . ']' : '' ) . '';
            $output[] = ['name' => $multiName, 'contents' => (is_array($multiValue) ? reset($multiValue) : $multiValue)];

【参考方案3】:

我使用了上面的@DannyBevers 答案,但发现它不适用于需要作为多部分发送的深层嵌套数组,所以这里有一个替代解决方案:

// fake nested array to be sent multipart by guzzle
$array = array(
        'title' => 'Test title',
        'content' => 'Test content',
        'id' => 17,
        'Post' => array(

                0 => array(
                        'id' => 100027,
                        'name' => 'Fake post title',
                        'content' => 'More test content ',
                        'Comments' => array (

                                0 => 'My first comment',
                                1 => 'My second comment',
                                2 => 'My third comment'
                        )
                ),
                1 => array(
                        'id' => 100028,
                        'name' => 'Another fake post title',
                        'overall' => 2,
                        'content' => 'Even More test content ',
                        'Comments' => array (

                                0 => 'My other first comment',
                                1 => 'My other second comment',

                        )
                )

        )
);


$flatten = function($array, $original_key = '') use (&$flatten) 

    $output = [];

    foreach ($array as $key => $value) 

        $new_key = $original_key;

        if (empty($original_key)) 

            $new_key .= $key;

         else 

            $new_key .= '[' . $key . ']';

        

        if (is_array($value)) 

            $output = array_merge($output, $flatten($value, $new_key));

         else 

            $output[$new_key] = $value;

        
    

    return $output;

;


$flat_array = $flatten($array);

$data = [];

foreach($flat_array as $key => $value) 

    $data[] = [

            'name'  => $key,
            'contents' => $value

    ];




$response = $guzzle->request($type, $get, array('multipart' => $data));

【参考方案4】:

由于我遇到了完全相同的问题并且当我得到集合字段时,我有一个多嵌套级别数组!所以,我需要调整这里发布的功能。

我合并了@John 和@DannyBevers 解决方案以获得name 参数的完整密钥和contents 参数的值。 然后,我在multipart键下添加了函数结果

功能:

private function flatten($array, $prefix = "[", $suffix = "]") 
    global $i;
    $result = array();
    foreach($array as $key=>$value) 
        if(is_array($value)) 
            if($i == 0) 
                $result = $result + $this->flatten($value, $key.$prefix, $suffix);
            
            else 
                foreach ($this->flatten($value, $prefix . $key . $suffix."[", $suffix) as $k => $v)
                    $result[] = $v;
                
            
        
        else                 
            if($value instanceof UploadedFile)
                $result[] = ["name" => $prefix.$key.$suffix,
                    "filename" => $value->getClientOriginalName(),
                    "Mime-Type" => $value->getMimeType(),
                    "contents" => fopen($value->getPathname(), "r")];
            
            else 
                $result[] = ["name" => $prefix . $key . $suffix, "contents" => $value];
            
        
        $i++;
    
    return $result;

            [10] => Array
                (
                    [name] => requestbundle_issuingserviceproduct[technicalContact][email]
                    [contents] => patou@mail.fr
                )

        )

)

my 项目中,我的函数不会抛出任何错误,而 @DannyBevers 会抛出任何错误。

希望对您有所帮助!

为它使用漂亮的功能:

function getFlatten($key, array $data, $result = [])

    foreach ($data as $subKey => $value) 
        $subKey = $key . '[' . $subKey . ']';
        if (\is_array($value)) 
            $result = $this->getFlatten($subKey, $value, $result);
         else 
            $result[] = ['name' => $subKey, 'contents' => $value];
        
    

    return $result;

示例

   $data = [
        'first' => [
            'second' => ['third' => 12, 'third_a' => 13],
            'second_2' => 3,
            'second_3' => ['third_2' => ['fours' => 15]],
        ],
    ];

if (is_array($data)) 
    $request = getFlatten('main_key', $data)

输出

    0 => [
        'name' => 'main_key[first][second][third]'
        'contents' => 12
    ]
    1 => [
        'name' => 'main_key[first][second][third_a]'
        'contents' => 13
    ]
    2 => [
        'name' => 'main_key[first][second_2]'
        'contents' => 3
    ]
    3 => [
        'name' => 'main_key[first][second_3][third_2][fours]'
        'contents' => 15
    ]

上述解决方案都不适合我,因为我的数组结构具有***值以及嵌套。

我创建了解决问题的 Gist:https://gist.github.com/matthew-inamdar/a17701f948770ac0a55acd9d12445645

你可以简单地使用如下:

$data = [
    'name' => 'John',
    'language' => [
        'main' => 'English',
        'secondary' => [
            0 => 'Spanish',
            1 => 'German'
        ]
    ],
];

$flattened = (new Flatten())->flatten($data);

$flattened = [
    ['name' => 'name', 'contents' => 'John'],
    ['name' => 'language[main]', 'contents' => 'English'],
    ['name' => 'language[secondary][0]', 'contents' => 'Spanish'],
    ['name' => 'language[secondary][1]', 'contents' => 'German']
];

@见https://github.com/guzzle/guzzle/issues/1679#issuecomment-342233663

使用 http_build_query 获取扁平化名称,然后构建多部分。

$multipart = [];
$vars = explode('&', http_build_query($postData));
foreach ($vars as $var) 
    list($nameRaw, $contentsRaw) = explode('=', $var);
    $name = urldecode($nameRaw);
    $contents = urldecode($contentsRaw);
    $multipart[] = ['name' => $name, 'contents' => $contents];

示例数据:

$array = [
  "doc_id" => 2,
  "data" => [
    [
      "field" => "10"
      "value" => "test10"
    ],
    [
      "field" => "11"
      "value" => "test11"
    ]
  ]
]

编码多维数组

$outputArray = explode('&', urldecode(http_build_query($array)))

输出:

array[
  0 => "doc_id =2",
  1 => "data[0][field]=10",
  2 => "data[0][value]=test10",
  3 => "data[1][field]=11",
  4 => "data[1][value]=test11"
]

添加帖子数据:

foreach ($outputArray as $data) 
    list($key, $value) = explode('=', $data);
    $postData[] = ['name' => $key, 'contents' => $value];

以上是关于Guzzle 使用嵌套数组发布多部分请求的主要内容,如果未能解决你的问题,请参考以下文章

使用 Guzzle 发布表单数据总是返回 404

Guzzle 请求:发布正文数据

如何在邮递员的同一请求中发送多部分/表单数据和嵌套 json?

使用 Guzzle 在 post 请求中传递数组

Postman:解析多部分 servlet 请求失败;嵌套异常是 java.lang.IllegalStateException, MultipartFile, REST

通过邮递员发送二维字节数组(多个文件)作为多部分请求
