Question

我正在尝试使用Zinc API编写Python脚本来购买亚马逊（请参阅：https://zinc.io/docs/#full-api）。我应该能够通过一个POST请求执行此操作，因此我阅读了有关urllib和urllib2 here的信息。

但是，当我运行脚本时，我收到此错误：

{"_type":"error","code":"invalid_json","message":"The JSON in your request could not be parsed."}

我非常准确地关注了Zinc的代码，所以我不确定为什么我会收到错误。

以下是我正在运行的内容（注意：我的个人信息被排除在外，但在我运行脚本时包括在内）：

import urllib
import urllib2
import json

url = 'https://api.zinc.io/v0/order'
values = {"client_token" : "public",
          "retailer" : "amazon",
          "products" :[{"product_id" : "0679753354", "quantity" : 1}],
          "max_price" : 1700, "shipping_address" : {
              "first_name" : "NAME",
              "last_name" : "NAME",
              "address_line1" : "ADDRESS",
              "address_line2" : "",
              "zip_code" : "ZIP",
              "city" : "CITY",
              "state" : "STATE",
              "country" : "US"
              },
          "is_gift" : False,
          "shipping_method" : "cheapest",
          "payment_method" : {
              "name_on_card" : "NAME",
              "number" : "CARDNUMBER",
              "security_code" : "SECCODE",
              "expiration_month" : 1,
              "expiration_year": 2015
              },
          "billing_address" : {
              "first_name" : "NAME",
              "last_name" : "NAME",
              "address_line1" : "ADDRESS",
              "address_line2" : "",
              "zip_code" : "ZIP",
              "city" : "CITY",
              "state" : "STATE",
              "country" : "US",
              "phone_number" : "PHONE"
              },
          "retailer_credentials" : {
              "email" : "EMAIL",
              "password" : "PASSWORD"}
          }

data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()

print the_page

关于如何解决这个JSON解析问题的任何想法都会非常感激，因为我还没能弄清楚错误是什么。

Answer 1

您不想对该数据进行urlencode。这是表单值，而不是JSON。

此外，您已导入json模块，但您未在数据上使用该模块。你应该这样做：

data = json.dumps(values)
req = urllib2.Request(url, data, {'content-type': 'application/json'})

虽然使用第三方requests库更容易也更好。

Answer 2

您正在对您的请求进行网址编码，但不会将Python数据转换为服务器可以理解的JSON。您应该调用json.dumps（values）而不是调用urllib.urlencode（values）。

例如：

import urllib
import urllib2
import json

url = 'https://api.zinc.io/v0/order'
values = {"client_token" : "public",
          "retailer" : "amazon",
          "products" :[{"product_id" : "0679753354", "quantity" : 1}],
          "max_price" : 1700, "shipping_address" : {
              "first_name" : "NAME",
              "last_name" : "NAME",
              "address_line1" : "ADDRESS",
              "address_line2" : "",
              "zip_code" : "ZIP",
              "city" : "CITY",
              "state" : "STATE",
              "country" : "US"
              },
          "is_gift" : False,
          "shipping_method" : "cheapest",
          "payment_method" : {
              "name_on_card" : "NAME",
              "number" : "CARDNUMBER",
              "security_code" : "SECCODE",
              "expiration_month" : 1,
              "expiration_year": 2015
              },
          "billing_address" : {
              "first_name" : "NAME",
              "last_name" : "NAME",
              "address_line1" : "ADDRESS",
              "address_line2" : "",
              "zip_code" : "ZIP",
              "city" : "CITY",
              "state" : "STATE",
              "country" : "US",
              "phone_number" : "PHONE"
              },
          "retailer_credentials" : {
              "email" : "EMAIL",
              "password" : "PASSWORD"}
          }

req = urllib2.Request(url, json.dumps(values))
response = urllib2.urlopen(req)
the_page = response.read()

print the_page
