在 Ebay 中为订单创建发货时出错

Question

这个错误已经困扰了我大约一个星期了...我正在尝试在 Ebay 中创建货件，但在响应中收到 500 错误代码。这是文档 https://developer.ebay.com/api-docs/sell/fulfillment/resources/order/shipping_fulfillment/methods/createShippingFulfillment

的 link

我在生产环境中运行这段代码：

  @header = {
    'Content-Type': 'application/json',
    'Authorization': "Bearer #{@token}"
  }

  uri = URI.parse("https://api.ebay.com/sell/fulfillment/v1/order/#{order.order_number}/shipping_fulfillment")

  # Create the HTTP objects
  http = Net::HTTP.new(uri.host, uri.port)
  http.use_ssl = true
  items = []
  order.items.each do |i|
    items << {"lineItemId": i[:id]}
  end
  params = {
    "lineItems": items,
    "shippedDate": Time.parse(date).strftime("%Y-%m-%dT%H:%M:%S.000Z"),
    "shippingCarrierCode": "USPS",
    "trackingNumber": tracking_number
  }

  request = Net::HTTP::Post.new(uri.request_uri, @header)


  request.body = params.to_json
  response = http.request(request)
  puts response.code #prints 500

我的错误：

{"errors": [{
"errorId": 2003,
"domain": "ACCESS",
"category": "APPLICATION",
"message": "Internal error",
"longMessage": "There was a problem with an eBay internal system or process. Contact eBay developer support for assistance",
"parameters": [{
    "name": "reason",
    "value": "Failed to transform underlying error response, see logs."
}]
}]}

我已支付高级开发人员支持费用，但尚未收到回复。任何帮助将不胜感激。我试过用空的 body 提交相同的请求，但这并没有改变响应。我也试过改变 headers。如果我添加 'Accept': 'application/json'，那么我会收到 500 错误和一个空的 body。这没有任何意义。

更新

根据评论中的建议，我尝试将 params hash 更改为：

params = {
    "lineItems": "[{\"lineItemId\":10025031700524,\"quantity\":1}]",
    "shippedDate": "2020-05-01T08:05:00.000Z",
    "shippingCarrierCode": "USPS",
    "trackingNumber": "9400111899562795104724"
  }

我也尝试了运行后续请求。我还尝试在 body 中提交以下 JSON:

request.body = {
    "lineItems": [
      {
        "lineItemId": "10025031700524",
        "quantity": "1"
      }
    ],
    "shippedDate": "2020-05-01T08:05:00.000Z",
    "shippingCarrierCode": "USPS",
    "trackingNumber": "9400111899562795104724"
  }.to_json

每次尝试都会产生与之前完全相同的错误。我也尝试将数量更改为整数和字符串。

请求内容中：

POST /sell/fulfillment/v1/order/24-04954-08727/shipping_fulfillment
content-type: application/json
authorization: Bearer v#i^1XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX=
accept-encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3
accept: */*
user-agent: Ruby
connection: close
host: api.ebay.com
content-length: 159
content-type: application/x-www-form-urlencoded
{"lineItems":[{"lineItemId":"10025031700524"}],"shippedDate":"2020-05- 01T08:05:00.000Z","shippingCarrierCode":"USPS","trackingNumber":"9400111899562795104724"}

我想到 content-type 出现了两次。

在运行 irb 中的一些示例之后，net/http 库似乎使用字符串，而不是符号。通过在 @header 定义中使用 :，键将被解释为符号。

引用Ruby documentation：

Hashes

A hash is created using key-value pairs between { and }:
{ "a" => 1, "b" => 2 }
Both the key and value may be any object.

You can create a hash using symbol keys with the following syntax:
{ a: 1, b: 2 }
This same syntax is used for keyword arguments for a method.

Like Symbol literals, you can quote symbol keys.
{ "a 1": 1, "b #{1 + 1}": 2 }
is equal to
{ :"a 1" => 1, :"b 2" => 2 }
See Hash for the methods you may use with a hash.

要使用字符串键，请使用 => 而不是 :。

对你来说这意味着改变：

@header = {
  'Content-Type': 'application/json',
  'Authorization': "Bearer #{@token}"
}

进入：

@header = {
  'Content-Type' => 'application/json',
  'Authorization' => "Bearer #{@token}"
}
