Question

我想使用来自以下网址的OAuth客户端通过GET请求从WooCommerce获取订单： Python OAuth WooCommerce

我的代码如下所示：

import time
from hashlib import sha1
import hmac
import binascii
from urllib import quote, urlencode
import httplib2
from collections import OrderedDict
import json

def key_compare(a, b):
    return cmp(a[0], b[0])

class Restful_Client(object):
    """docstring for Restful_Client"""
    def __init__(self, endpoint, consumer_key, consumer_secret):
        super(Restful_Client, self).__init__()
        self.consumer_key = consumer_key
        self.consumer_secret = consumer_secret
        self.endpoint = endpoint

    def make_request(self, resource, params, method='GET' ):
        oauth_params = {
            'oauth_consumer_key': self.consumer_key,
            'oauth_nonce': self.gen_nonce(),
            'oauth_timestamp': self.gen_timestamp(),
            'oauth_signature_method': 'HMAC-SHA1',
            # 'oauth_version':'1.0'
        }
        oauth_params['oauth_signature'] = self.gen_signature(
            resource,
            OrderedDict( params.items() + oauth_params.items() ),
            method
        )
        params = OrderedDict( params.items() + oauth_params.items() )
        clean_params = self.sort_params(self.normalize_params(params))
        uri = endpoint + resource
        p_string = urlencode(clean_params)
        return httplib2.Http().request(uri + '?' + p_string)

    def gen_signature(self, resource, params, method):
        base_request_uri = quote(self.endpoint + resource, safe = "")
        clean_params = self.sort_params(
            self.normalize_params(
                self.normalize_params(
                    params
                )
            )
        )
        query_string = '%26'.join([
            key + '%3D' + value\
            for key, value in clean_params.iteritems()
        ])
        raw_string = '&'.join([method, base_request_uri, query_string]) 
        hashed = hmac.new(self.consumer_secret, raw_string, sha1)
        return binascii.b2a_base64( hashed.digest() )[:-1]

    def normalize_string(self, string):
        return quote(str(string), safe="")

    def normalize_params(self, params):
        return OrderedDict( [
            (self.normalize_string(key), self.normalize_string(value))\
            for key, value \
            in params.iteritems()
        ])

    def sort_params(self, params):
        return OrderedDict(sorted(
            params.iteritems(),
            cmp=key_compare
        ))

    def gen_timestamp(self):
        return int(time.time())

    def gen_nonce(self):
        return hex(self.gen_timestamp())

if __name__ == "__main__":
    store_url = '<STORE URL HERE>'
    api_base = 'wc-api'
    api_ver = 'v3'
    endpoint = "%s/%s/%s/" % (store_url, api_base, api_ver)

    consumer_key = '<CK HERE>'
    consumer_secret = '<CS HERE>&' # the & is necessary for api ver v3

    resource = 'orders'
    parameters = {}

    rc = Restful_Client(endpoint, consumer_key, consumer_secret)
    r, c = rc.make_request(resource, parameters, 'GET')
    print json.dumps(r, indent=1)
    c = json.loads(c)
    print json.dumps(c, indent=1)

此代码导致WooCommerce发送10个最新订单，这些订单将存储在变量c中。在变量r中，有关于存储的请求的更多细节。这是变量r的示例输出：

{
 "status": "200", 
 ...,
 "content-location": "<<STORE URL>/wc-api/v3/orders?oauth_consumer_key=<CK HERE>&oauth_nonce=0x560bc13c&oauth_signature=Ln6IbXciDSNjTfraKe1Cx%252FPRDkU%253D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1443610940", 
 "x-cache": "MISS", 
 "x-wc-total": "1180", 
 ..., 
 "x-wc-totalpages": "118", 
 "-content-encoding": "gzip", 
 "link": "<<STORE URL>/wc-api/v3/orders?oauth_consumer_key=<CK HERE>&oauth_nonce=0x560bc13c&oauth_signature=Ln6IbXciDSNjTfraKe1Cx%2FPRDkU%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1443610940&page=2>; rel=\"next\", <<STORE URL>/wc-api/v3/orders?oauth_consumer_key=<CK HERE>&oauth_nonce=0x560bc13c&oauth_signature=Ln6IbXciDSNjTfraKe1Cx%2FPRDkU%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1443610940&page=118>; rel=\"last\"", 
 ..., 
 "content-type": "application/json; charset=UTF-8", 
 "accept-ranges": "bytes"
}

与关键字“链接”相关联，链接有一些请求所基于的链接，并且可以看到订单请求是在不同的页面中发送的。显然，上面的代码总是请求最后一页。

我的问题：

代码中的哪个位置是指定的请求页面？

如何指定我想要请求的页面，如果可能，更改每页显示的订单数量？

非常感谢每一位帮助！

（我的编程经验有限。）
