         q='lectures',
         cx='013036536707430787589:_pqjad5hr1a',
         num=10, #Valid values are integers between 1 and 10, inclusive.
    ).execute() 

    for value in res:
        #print value
        if 'items' in value:
            for results in res[value]:
                print results['formattedUrl']

  main()

Answer 1

响应对象包含"nextPage"字典.您可以使用它来确定下一个请求的起始索引.像这样:

res = service.cse().list(
     q='lectures',
     cx='013036536707430787589:_pqjad5hr1a',
     num=10, #Valid values are integers between 1 and 10, inclusive.
).execute() 

next_response = service.cse().list(
     q='lectures',
     cx='013036536707430787589:_pqjad5hr1a',
     num=10,
     start=res['queries']['nextPage'][0]['startIndex'],
).execute() 

Answer 2

我的建议是添加下一个参数。在当前软件中，您有q，cx和num。您可以尝试添加start = 10，然后执行代码。

res = service.cse().list(
    q='lectures',
    cx='013036536707430787589:_pqjad5hr1a',
    num=10,
    start=10,
).execute()

第一个结果页网址没有开始参数。第二页的URL包含start = 10参数。第三页的URL包含start = 20 ...

祝好运
