经过几天的研究，我想出了一个基本的Python代码，从Idealista API检索真实的房地产数据。

def get_oauth_token():
http_obj = Http()
url = "https://api.idealista.com/oauth/token"
apikey= urllib.parse.quote_plus('Provided_API_key')
secret= urllib.parse.quote_plus('Provided_API_secret')
auth = base64.encode(apikey + ':' + secret)
body = {'grant_type':'client_credentials'}
headers = {'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8','Authorization' : 'Basic ' + auth}
resp, content = http_obj.request(url,method='POST',headers=headers, body=urllib.parse.urlencode(body))
return content

字符串
该函数将返回一个JSON，其中包含OAuth2 token和会话时间（以秒为单位）。之后，要查询API，就像下面这样简单：

def search_api(token):
http_obj = Http()
url = "http://api.idealista.com/3.5/es/search?center=40.42938099999995,-3.7097526269835726&country=es&maxItems=50&numPage=1&distance=452&propertyType=bedrooms&operation=rent"
headers = {'Authorization' : 'Bearer ' + token}
resp, content = http_obj.request(url,method='POST',headers=headers)
return content

型
这一次，我们将在content var中找到我们要查找的数据，同样是JSON。

这是我的代码，改进#3.这运行好！对我来说！只把你的apikey和你的密码（秘密）.

import pandas as pd
import json
import urllib
import requests as rq
import base64

def get_oauth_token():
    url = "https://api.idealista.com/oauth/token"    
    apikey= 'your_api_key' #sent by idealista
    secret= 'your_password'  #sent by idealista
    auth = base64.b64encode(apikey + ':' + secret)
    headers = {'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8' ,'Authorization' : 'Basic ' + auth}
    params = urllib.urlencode({'grant_type':'client_credentials'})
    content = rq.post(url,headers = headers, params=params)
    bearer_token = json.loads(content.text)['access_token']
    return bearer_token

def search_api(token, url):  
    headers = {'Content-Type': 'Content-Type: multipart/form-data;', 'Authorization' : 'Bearer ' + token}
    content = rq.post(url, headers = headers)
    result = json.loads(content.text)['access_token']
    return result

country = 'es' #values: es, it, pt
locale = 'es' #values: es, it, pt, en, ca
language = 'es' #
max_items = '50'
operation = 'sale' 
property_type = 'homes'
order = 'priceDown' 
center = '40.4167,-3.70325' 
distance = '60000'
sort = 'desc'
bankOffer = 'false'

df_tot = pd.DataFrame()
limit = 10

for i in range(1,limit):
    url = ('https://api.idealista.com/3.5/'+country+'/search?operation='+operation+#"&locale="+locale+
           '&maxItems='+max_items+
           '&order='+order+
           '&center='+center+
           '&distance='+distance+
           '&propertyType='+property_type+
           '&sort='+sort+ 
           '&numPage=%s'+
           '&language='+language) %(i)  
    a = search_api(get_oauth_token(), url)
    df = pd.DataFrame.from_dict(a['elementList'])
    df_tot = pd.concat([df_tot,df])

df_tot = df_tot.reset_index()

字符串

这不能被标记为正确答案，因为

auth = base64.encode(apikey + ':' + secret)
body = {'grant_type':'client_credentials'}
headers = {'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8','Authorization' : 'Basic ' + auth}

字符串
将给予您TypeError：

can only concatenate str (not "bytes") to str

型
由于base64encode返回一个字节类型对象.
Idealista API在文档方面确实非常有限，但我认为这是一种更好的方法，因为我不使用unlimited libs（仅限本机）：

#first request
message = API_KEY + ":" + SECRET
auth = "Basic " + base64.b64encode(message.encode("ascii")).decode("ascii")

headers_dic = {"Authorization" : auth, 
               "Content-Type" : "application/x-www-form-urlencoded;charset=UTF-8"}

params_dic = {"grant_type" : "client_credentials",
              "scope" : "read"}


r = requests.post("https://api.idealista.com/oauth/token", 
                  headers = headers_dic, 
                  params = params_dic)

型
这工作完美，只有python请求和base64模块。
问候

我发现了一些错误。至少，我不能运行它。我相信，我改进了这一点：

import pandas as pd
import json
import urllib
import requests as rq
import base64

def get_oauth_token(): 

    url = "https://api.idealista.com/oauth/token"    

    apikey= 'your_api_key' #sent by idealist
    secret= 'your_password' #sent by idealista
    apikey_secret = apikey + ':' + secret
    auth = str(base64.b64encode(bytes(apikey_secret, 'utf-8')))[2:][:-1]

    headers = {'Authorization' : 'Basic ' + auth,'Content-Type': 'application/x-www-form- 
    urlencoded;charset=UTF-8'}
    params = urllib.parse.urlencode({'grant_type':'client_credentials'}) #,'scope':'read'
    content = rq.post(url,headers = headers, params=params)
    bearer_token = json.loads(content.text)['access_token']

    return bearer_token

def search_api(token, URL):  
    headers = {'Content-Type': 'Content-Type: multipart/form-data;', 'Authorization' : 'Bearer ' + token}
    content = rq.post(url, headers = headers)
    result = json.loads(content.text)

    return result

这是有效的：

import requests

import urllib.parse

def get_oauth_token():
    url = "https://api.idealista.com/oauth/token"

    # Your API key and secret (replace with your actual key and secret)
    api_key = 'your_string'
    api_secret = 'your_string'

    # URL encode your key and secret, concatenate them, and encode to Base64
    apikey_encoded = urllib.parse.quote_plus(api_key)
    secret_encoded = urllib.parse.quote_plus(api_secret)
    credentials = f"{apikey_encoded}:{secret_encoded}"
    encoded_credentials = base64.b64encode(credentials.encode()).decode()

    headers = {
        'Authorization': 'Basic ' + encoded_credentials,
        'Content-Type': 'application/x-www-form-urlencoded'
    }

    body = {
        'grant_type': 'client_credentials'
    }

    # Make the POST request
    response = requests.post(url, headers=headers, data=body)

    # Handle the response
    if response.status_code == 200:
        return response.json()  # Returns the JSON response with the token
    else:
        raise Exception(f"Failed to obtain token: {response.status_code}, {response.text}")

# Use the function to get the token
# try:

    params = {

        'distance': '452',
        'propertyType': 'bedrooms',
        'operation': 'rent'
    }

    # Make the GET or POST request
    # If your API requires a GET request, change it to requests.get
    response = requests.post(url, headers=headers, params=params)

    # Handle the response
    if response.status_code == 200:
        return response.json()  # Returns the JSON response
    else:
        raise Exception(f"API request failed: {response.status_code}, {response.text}")

# Usage example
# token = "your_access_token"
# try:
#     result = search_api(token)
#     print(result)
# except Exception as e:
#     print("Error:", e)

TOKEN = 'returned_string'

try:
    result = search_api(TOKEN)
    print(result)
except Exception as e:
    print("Error:", e)
