Question

我正在使用ipinfo.io库检查用户所在的国家/地区，并且一切正常。

我正在使用此代码提取数据

$.get("https://ipinfo.io?token=0000000000", function(response) {
    console.log(response.ip, response.country);
   }, "jsonp")

我在https://ipinfo.io/developers/full-country-names中读到，我可以使用完整的国家/地区名称json文件，但是我不知道如何将其映射到一起甚至都不知道从哪里开始。有什么建议吗？

谢谢！

Answer 1

一种方法是将names.json文件本地存储在您的项目环境中。然后，您可以检查国家/地区代码是否是该对象文字的键。如果找到，则可以打印该值。

类似这样的东西：

var countries = {"BD": "Bangladesh", "BE": "Belgium", "BF": "Burkina Faso"}; // your json object names.json
var foundCountryCode = "BE"; // the country code you found
var countryName = countries[foundCountryCode]; // here you get the name
console.log(countryName); // do stuff

Answer 2

要获取带有国家/地区代码作为对象的国家/地区名称的键，您可以

export const validatePassword = password => {
  const re = /^(?=.*[A-Za-z])(?=.*\d)[a-zA-Z0-9!@#$%^&*()~¥=_+}{":;'?/>.<,`\-\|\[\]]{6,50}$/
  return re.test(password)
}

请注意，我使用的是您提到的教程提供的json，它使用fetch("http://country.io/names.json") .then(response => response.json()) .then(countryMap => { console.log(countryMap); });协议，因此，如果要在应用程序的前端运行它，请确保它不会自动重写{ {1}}到http或使用其他公共托管文件。

然后您可以正常访问ex的对象参数。

http

首先在所有国家/地区列表中创建变量

//Usage: HttpDownload("http://www.localhost/files/imagine.jpg", "seo.jpg");

    static async void HttpDownload(string remoteFileOrUri, string localFileName)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(remoteFileOrUri));
        HttpWebResponse response = (HttpWebResponse)await request.GetResponseAsync();
        StreamReader rdr = new StreamReader(response.GetResponseStream());
        StreamWriter sw = new StreamWriter(File.OpenWrite(localFileName));

        sw.Write(rdr.ReadToEnd());
        sw.Flush();

        rdr.Close();
        sw.Close();
        Console.WriteLine("fin!");
    }

之后，您可以执行以下操作来提取数据

var country={"BD": "Bangladesh", "BE": "Belgium", "BF": "Burkina Faso", "BG": "Bulgaria", "BA": "Bosnia and Herzegovina", "BB": "Barbados", "WF": "Wallis and Futuna", "BL": "Saint Barthelemy", "BM": "Bermuda", "BN": "Brunei", "BO": "Bolivia", "BH": "Bahrain", "BI": "Burundi", "BJ": "Benin", "BT": "Bhutan", "JM": "Jamaica", "BV": "Bouvet Island", "BW": "Botswana", "WS": "Samoa", "BQ": "Bonaire, Saint Eustatius and Saba ", "BR": "Brazil", "BS": "Bahamas", "JE": "Jersey", "BY": "Belarus", "BZ": "Belize", "RU": "Russia", "RW": "Rwanda", "RS": "Serbia", "TL": "East Timor", "RE": "Reunion", "TM": "Turkmenistan", "TJ": "Tajikistan", "RO": "Romania", "TK": "Tokelau", "GW": "Guinea-Bissau", "GU": "Guam", "GT": "Guatemala", "GS": "South Georgia and the South Sandwich Islands", "GR": "Greece", "GQ": "Equatorial Guinea", "GP": "Guadeloupe", "JP": "Japan", "GY": "Guyana", "GG": "Guernsey", "GF": "French Guiana", "GE": "Georgia", "GD": "Grenada", "GB": "United Kingdom", "GA": "Gabon", "SV": "El Salvador", "GN": "Guinea", "GM": "Gambia", "GL": "Greenland", "GI": "Gibraltar", "GH": "Ghana", "OM": "Oman", "TN": "Tunisia", "JO": "Jordan", "HR": "Croatia", "HT": "Haiti", "HU": "Hungary", "HK": "Hong Kong", "HN": "Honduras", "HM": "Heard Island and McDonald Islands", "VE": "Venezuela", "PR": "Puerto Rico", "PS": "Palestinian Territory", "PW": "Palau", "PT": "Portugal", "SJ": "Svalbard and Jan Mayen", "PY": "Paraguay", "IQ": "Iraq", "PA": "Panama", "PF": "French Polynesia", "PG": "Papua New Guinea", "PE": "Peru", "PK": "Pakistan", "PH": "Philippines", "PN": "Pitcairn", "PL": "Poland", "PM": "Saint Pierre and Miquelon", "ZM": "Zambia", "EH": "Western Sahara", "EE": "Estonia", "EG": "Egypt", "ZA": "South Africa", "EC": "Ecuador", "IT": "Italy", "VN": "Vietnam", "SB": "Solomon Islands", "ET": "Ethiopia", "SO": "Somalia", "ZW": "Zimbabwe", "SA": "Saudi Arabia", "ES": "Spain", "ER": "Eritrea", "ME": "Montenegro", "MD": "Moldova", "MG": "Madagascar", "MF": "Saint Martin", "MA": "Morocco", "MC": "Monaco", "UZ": "Uzbekistan", "MM": "Myanmar", "ML": "Mali", "MO": "Macao", "MN": "Mongolia", "MH": "Marshall Islands", "MK": "Macedonia", "MU": "Mauritius", "MT": "Malta", "MW": "Malawi", "MV": "Maldives", "MQ": "Martinique", "MP": "Northern Mariana Islands", "MS": "Montserrat", "MR": "Mauritania", "IM": "Isle of Man", "UG": "Uganda", "TZ": "Tanzania", "MY": "Malaysia", "MX": "Mexico", "IL": "Israel", "FR": "France", "IO": "British Indian Ocean Territory", "SH": "Saint Helena", "FI": "Finland", "FJ": "Fiji", "FK": "Falkland Islands", "FM": "Micronesia", "FO": "Faroe Islands", "NI": "Nicaragua", "NL": "Netherlands", "NO": "Norway", "NA": "Namibia", "VU": "Vanuatu", "NC": "New Caledonia", "NE": "Niger", "NF": "Norfolk Island", "NG": "Nigeria", "NZ": "New Zealand", "NP": "Nepal", "NR": "Nauru", "NU": "Niue", "CK": "Cook Islands", "XK": "Kosovo", "CI": "Ivory Coast", "CH": "Switzerland", "CO": "Colombia", "CN": "China", "CM": "Cameroon", "CL": "Chile", "CC": "Cocos Islands", "CA": "Canada", "CG": "Republic of the Congo", "CF": "Central African Republic", "CD": "Democratic Republic of the Congo", "CZ": "Czech Republic", "CY": "Cyprus", "CX": "Christmas Island", "CR": "Costa Rica", "CW": "Curacao", "CV": "Cape Verde", "CU": "Cuba", "SZ": "Swaziland", "SY": "Syria", "SX": "Sint Maarten", "KG": "Kyrgyzstan", "KE": "Kenya", "SS": "South Sudan", "SR": "Suriname", "KI": "Kiribati", "KH": "Cambodia", "KN": "Saint Kitts and Nevis", "KM": "Comoros", "ST": "Sao Tome and Principe", "SK": "Slovakia", "KR": "South Korea", "SI": "Slovenia", "KP": "North Korea", "KW": "Kuwait", "SN": "Senegal", "SM": "San Marino", "SL": "Sierra Leone", "SC": "Seychelles", "KZ": "Kazakhstan", "KY": "Cayman Islands", "SG": "Singapore", "SE": "Sweden", "SD": "Sudan", "DO": "Dominican Republic", "DM": "Dominica", "DJ": "Djibouti", "DK": "Denmark", "VG": "British Virgin Islands", "DE": "Germany", "YE": "Yemen", "DZ": "Algeria", "US": "United States", "UY": "Uruguay", "YT": "Mayotte", "UM": "United States Minor Outlying Islands", "LB": "Lebanon", "LC": "Saint Lucia", "LA": "Laos", "TV": "Tuvalu", "TW": "Taiwan", "TT": "Trinidad and Tobago", "TR": "Turkey", "LK": "Sri Lanka", "LI": "Liechtenstein", "LV": "Latvia", "TO": "Tonga", "LT": "Lithuania", "LU": "Luxembourg", "LR": "Liberia", "LS": "Lesotho", "TH": "Thailand", "TF": "French Southern Territories", "TG": "Togo", "TD": "Chad", "TC": "Turks and Caicos Islands", "LY": "Libya", "VA": "Vatican", "VC": "Saint Vincent and the Grenadines", "AE": "United Arab Emirates", "AD": "Andorra", "AG": "Antigua and Barbuda", "AF": "Afghanistan", "AI": "Anguilla", "VI": "U.S. Virgin Islands", "IS": "Iceland", "IR": "Iran", "AM": "Armenia", "AL": "Albania", "AO": "Angola", "AQ": "Antarctica", "AS": "American Samoa", "AR": "Argentina", "AU": "Australia", "AT": "Austria", "AW": "Aruba", "IN": "India", "AX": "Aland Islands", "AZ": "Azerbaijan", "IE": "Ireland", "ID": "Indonesia", "UA": "Ukraine", "QA": "Qatar", "MZ": "Mozambique"}
