我有一个分配给字符串的路径:

<body>

<div id="results"></div>

//var myurl = "https://cors-anywhere.herokuapp.com/https://api.yelp.com/v3/businesses/search?term=sushi&location=austin";
var myurl = "https://cors-anywhere.herokuapp.com/https://api.yelp.com/v3/businesses/search/phone?phone=+15122750852";

$.ajax({
    url: myurl,
    headers: {
        'Authorization':'Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    },
    method: 'GET',
    dataType: 'json',
    success: function(data){
        // Grab the results from the API JSON return
        var totalresults = data.total;
        // If our results are greater than 0, continue
        if (totalresults > 0){
            // Display a header on the page with the number of results
            $('#results').append('<h5>We discovered ' + totalresults + ' results!</h5>');
            // Itirate through the JSON array of 'businesses' which was returned by the API
            $.each(data.businesses, function(i, item) {
                // Store each business's object in a variable
                var id = item.id;
                var alias = item.alias;
                var phone = item.display_phone;
                var image = item.image_url;
                var name = item.name;
                var rating = item.rating;
                var reviewcount = item.review_count;

                // Append our result into our page
                $('#results').append('<div id="' + id + '" style="margin-top:50px;margin-bottom:50px;"><img src="' + image + '" style="width:200px;height:150px;"><br>We found <b>' + name + '</b> (' + alias + ')<br>Business ID: ' + id + '<br> Located at: ' + address + ' ' + city + ', ' + state + ' ' + zipcode + '<br>The phone number for this business is: ' + phone + '<br>This business has a rating of ' + rating + ' with ' + reviewcount + ' reviews.</div>');
            });
        } else {
            // If our results are 0; no businesses were returned by the JSON therefor we display on the page no results were found
            $('#results').append('<h5>We discovered no results!</h5>');
        }

但是,每台计算机的'llb'前缀可以是不同的字符串,我需要将其分配给任意值,该值将读取用户计算机为此特定目录设置的任何内容,例如:

string = 'pathos/llb_cube/uni/ToolSub.pm'

但是我不知道要为此使用什么功能或正则表达式。

1 个答案:

答案 0 :(得分:1)

您可以使用点.来表示“任何字符”:

string = r'pathos/.*_cube/uni/ToolSub\.pm'
  • 我在字符串末尾转义了点。

  • *星号表示0个或多个重复。

  • 我使用了原始的字符串文字:r'...',因此我可以写反斜杠而不必将其转义。

如果您需要一定数量的字符,请使用.{x}现在,您可以使用正则表达式来匹配您的路径

for path in path_list:
    match = re.match(string, path)
    if match:
        print(match.group(0))
