将 pandas DataFrame 行转换为 JSON 模式，然后发出 POST 请求

Question

我有一个 JSON 格式的数据集，如下所示：

>>> finalJSON
'"company": {"name": "Micro inc.", "founders": {"name": "Jim D", "name": "Susan A"}, 
 "company": {"name": "Vitacore", "founders": {"name": "Billy B", "name": "Sally Q", "name": "Mark G"}'
.....

我需要遍历并发送以下各项：

'"company": {"name": "Micro inc.", "founders": {"name": "Jim D", "name": "Susan A"},

到这样的 POST 请求：

d = []
for company in FinalJSON:
    p = requests.post((url + '/ratio'), json=company, headers=headers)
    if(p.status_code == 200):
            print p.text
            d.append(p.text)
    else:
            print(p.status_code)
            print "Error"

编辑/更新

希望这是我正在尝试做的更完整的示例。我有一个 Pandas DataFrame，其中包含这样的公司名称和员工：

>>> print name_frame
... 
               name    name    name    name        name
Micro inc.      NaN    Jim D  Susan A      NaN       NaN
Vitacore    Billy B      NaN  Sally Q   Mark G       NaN

我需要做的就是将它转换成这样的 JSON 格式：

finalJSON = { 
    "company":{
        "name": "Micro inc.",
        "founders": {
            "name": "Jim D",
            "name": "Susan A",
            }
    }
    "company":{
        "name": "Vitacore",
        "founders": {
            "name": "Billy B",
            "name": "Sall Q", 
            "name":"Mark G",
        }

在previous question 中，有人建议我尝试一下以获得所需的 JSON 格式：

finalJSON = []
for company, names in df.iterrows():
    names = ['"{0}"'.format(name) for name in names.dropna().tolist()]
    names_json_str = ('"name": ' if names else '') + ', "name": '.join(names)
    finalJSON.append('"company": {"name": "' + company + '", "founders": {' + names_json_str + '}')
finalJSON = ', '.join(finalJSON)

>>> finalJSON
'"company": {"name": "Micro inc.", "founders": {"name": "Jim D", "name": "Susan A"}, 
 "company": {"name": "Vitacore", "founders": {"name": "Billy B", "name": "Sally Q", "name": "Mark G"}'

所以现在我正在将转换与发布请求集成：

for company, names in name_frame.iterrows():
    names = ['"{0}"'.format(name) for name in names.dropna().tolist()]
    names_json_str = ('"name": ' if names else '') + ', "name": '.join(names)
    payload = '"company": {"name": "' + company + '", "founders": {' + names_json_str + '}'
    p = requests.post((url), json=payload, headers=headers)
    if(p.status_code == 200):
            print p.text
            d.append(p.text)
    else:
            print(p.status_code)
            print "Error"

虽然payload实际上不被认为是JSON可序列化的

TypeError: set([' + names_json_str + ']) is not JSON serializable

Answer 1

所以基本上是这样的：

 payload = '"company": {"name": "' + company + '", "founders": {' + names_json_str + '}'

API 的格式错误，修复它解决了问题

Answer 2

如何格式化 json 字符串完全取决于服务器的要求。

如果服务器接受公司 json 字符串为：

{"company": {"name": "Micro inc.", "founders": ["Jim D", "Susan A"]}}

你可以这样做：

finalJSON = []
rows = [('Micro inc.', ('Jim D', 'Susan A')),
        ('Vitacore', ('Billy B', 'Sally Q', 'Mark G'))]

for company_name, founders in rows: 
    # replace rows with real data, e.g. df.iterrows() 
    founders = ', '.join('"{}"'.format(founder) for founder in founders)
    json_str = '{{"company": {{"name": "{}", "founders": [{}]}}}}'.format(company_name, founders)
    finalJSON.append(json_str)

for company in finalJSON:
    print(company)
    # do stuff with company
