我正在使用一个 API,它要求我将一个数组放入表单字段中。给出的示例是用 PHP 编写的,但我使用的是 NodeJS。API 期望其中一个字段是一个数组,我很难弄清楚如何做到这一点。

PHP 示例如下所示:

$request->buildPostBody(array(
 'reference' => array(
 'line1' => 'Soundboard Setup',
 'line2' => 'Thank you for the order',
 'line3' => 'Our reference is: 3993029/11BD'
 ),
 'lines' => array(
 array('amount' => 50,
 'amount_desc' => 'panels',
 'description' => 'Sound buttons',
 'tax_rate' => 21,
 'price' => 5.952
 ),
 array('amount' => 1,
 'amount_desc' => '',
 'description' => 'Wooden case',
 'tax_rate' => 21,
 'price' => 249
 ),
 array('amount' => 10,
 'amount_desc' => 'hours',
 'description' => 'Support',
 'tax_rate' => 6,
 'price' => 62.5
 ),
 array('description' => 'This is a textline'))
));

在 NodeJS 中,我尝试过这个(除其他外):

var formData = {
  reference: [{'line1':'something'}], // <- this isn't going to fly
  lines: [{
    'amount': amount,
    'amount_desc': 'amount_desc',
    'description': 'description',
    'tax_rate': 0,
    'price': 100
  }]
};

request.post({
    url: 'https://www.factuursturen.nl/api/v1/invoices/',
    formData: formData,
    headers: {
      'Authorization': 'Basic ' + new Buffer(user + ':' + key).toString('base64')
    }
  }, function (error, response, body) {
    if (!error && [200, 201, 204].indexOf(response.statusCode) > 0) {
      console.log('posted ': ', response.statusCode);
    } else {
      console.log('problem with request: ', error, response.statusCode, body);
    }
  }
);

当我尝试像这样传递一个对象时:reference: {'line1':'foo'}我从节点收到一个错误:

node_modules/request/node_modules/combined-stream/node_modules/delayed-stream/lib/delayed_stream.js:33
  source.on('error', function() {});
         ^
TypeError: Object #<Object> has no method 'on'

我怎样才能最好地把这个圆钉钉在那个方孔里?

在 PHP 中,数组可以是数组也可以是关联数组,它们本质上是 JavaScript 中的对象。

array()指定

可以使用 array() 语言结构创建数组它采用任意数量的逗号分隔键 => 值对作为参数。

array(
    key  => value,
    key2 => value2,
    key3 => value3,
    ...
)

在 JavaScript 中,上面的内容本质上只是一个对象

{
    key: 'value',
    key2: 'value2'
    key3: 'value3'
    ...
}

它不会是一个包裹在数组中的对象[{…}],这就是你正在用你的reference

因此,要模仿 PHP 结构,您的数据应该是这样的:

var formData = {
  reference: {'line1':'something'}, // <- this should work now
  lines: [{  // <- this is still an array of objects [{}], as in PHP too, it's a nested array
    amount: amount,
    'amount_desc': 'amount_desc',
    'description': 'description',
    'tax_rate': 0,
    'price': 100
  }]
};

但这会导致另一个问题,正如您所注意到的。

         ^

这个错误在这里解释:https ://github.com/request/request/issues/1495 基本上form-data只需要简单的对象可能只有1级深。

尝试这个:

var formData = {
  'reference.line1': 'something',
  'lines[0].amount': amount,
  'lines[0].amount_desc': 'amount_desc',
  'lines[0].description': 'description',
  'lines[0].tax_rate': 0,
  'lines[0].price': 100,
};
