如何更正此脚本中的语法和格式？

Question

我试图通过将"f“参数添加到GET调用中来指定所需的字段(请参阅此处：Patentsview API Python 3.4)。

我认为问题在于我的格式和语法。

我尝试在"q“和"f”参数中添加几种不同的花括号。我返回不同的错误消息。

import requests

title = "computer" 
author = "Jobs" 
url = "http://www.patentsview.org/api/patents/query" 
data = { 
    "q":{ "_and":[ {"inventor_last_name":author}, {"_text_any":{"patent_title":title}}], 
    "f":["assignee_lastknown_city","assignee_lastknown_state","assignee_lastknown_country"]},
    "o":{"matched_subentities_only":"true"}
} 
resp = requests.post(url, json=data) 
with open("patents.txt", "w") as f:
    f.write(resp.text)

这是返回的内容：

{“状态”：“错误”，“有效载荷”：{“错误”：“q‘参数:应该只有一个json对象在顶层字典中。”，“代码”：“RQ3”}

我希望文件具有结果，而不是错误消息。

你的剧本中有不平衡的“}”。我纠正了他们。我一直无法测试这些更改是否有效。这是修改后的代码。我认为这是唯一的错误。

import requests

title = "computer" 
author = "Jobs" 
url = "http://www.patentsview.org/api/patents/query" 
data = {"q":{ "_and":[ {"inventor_last_name":author}, {"_text_any":{"patent_title":title}}]},"f":["assignee_lastknown_city","assignee_lastknown_state","assignee_lastknown_country"],"o":{"matched_subentities_only":"true"}} 
resp = requests.post(url, json=data) 
with open("patents.txt", "w") as f:
    f.write(resp.text)

如果对你有用，请告诉我。

查询数据中有错误。只要做一些修改，它就能工作：

import requests

title = "computer"
author = "Jobs"
url = "http://www.patentsview.org/api/patents/query"
data = {
    "q": {
        "_and": [
            {
                "inventor_last_name": author
            },
            {
                "_text_any": {
                    "patent_title": title
                }
            }
        ],
    },
    "f": [
        "assignee_lastknown_city",
        "assignee_lastknown_state",
        "assignee_lastknown_country"
    ],
    "o": {
        "matched_subentities_only": "true"
    }
}
resp = requests.post(url, json=data)
with open("patents.txt", "w") as f:
    f.write(resp.text)

基本上，我把f搬到了q外面
