Question

我正在尝试将curl请求转换为c＃请求，但它无法正常工作

卷曲请求

curl -X GET "http://www1.bloomingdales.com/shop/search?keyword=lace%2Btop"

上面的curl请求正常

C＃request

public lib_check ()
    {

        string url_1 = "http://www1.bloomingdales.com/shop/search/Pageindex%2CProductsperpage/1%2C180?keyword=women%20tank%20top";
        Console.Write (url+"request started");

        var request = (HttpWebRequest)WebRequest.Create(url_1);

        request.Method = WebRequestMethods.Http.Get;

        var response = request.GetResponse();
        using (var reader = new StreamReader(response.GetResponseStream()))
        {

            var json = reader.ReadToEnd ();

            console.write( json);

        }
    }

但是上面的c＃请求会抛出403禁止错误

如何修复c＃请求并使请求工作以获得200响应？

我猜它之所以被禁止，是因为你没有构建网站所期望的必要标题。您需要构建这些标头，并且可以在chrome中的开发人员工具中进行检查。请参阅下面的代码。

public T getUnique(){
    T distinct = null;
    int count = 0; // FIXME: move this initialization inside the i loop
    for (int i=0; i<vals.length; i++){
        distinct =  vals[i];
        for (int j = 0; j<vals.length; j++){
            if (vals[j] == vals[i]){ // FIXME: use .equals() not ==
                count++;
            }
            if (count == 1){ // FIXME: move this check outside the j loop
                return distinct;
            }
        }
    }
    if (distinct == null){ //FIXME: no check needed, just throw it
        throw new IllegalArgumentException();
    }
    return distinct; //FIXME: no valid return can reach this point
}

查看服务器所需的标头数量;尝试在开发工具处于活动状态时首先在浏览器中请求网址。

更新：如果由于超时问题而无法正常工作，最好以异步方式处理它。

string url_1 = @"http://www1.bloomingdales.com/shop/search/Pageindex%2CProductsperpage/1%2C180?keyword=women%20tank%20top";

var request = (HttpWebRequest)WebRequest.Create(url_1);

request.Method = "GET";   
request.Accept = "text/html";            
request.UserAgent = ".NET Framework Test Client"; // Some server prevent script like this so they validate some user-agents
request.MaximumAutomaticRedirections = int.MaxValue;
request.Timeout = 50000;

var response = request.GetResponse();
using (var reader = new StreamReader(response.GetResponseStream()))
{

    var json = reader.ReadToEnd();

    Console.Write(json);

}

我注意到结果不是json而是页面。可能是因为它不是API。根据需要调整代码，但裸骨已经存在。
