服务器403(禁止访问)错误并从IDictionary编码url [英] Server 403(Forbidden) error and encode url from IDictionary

问题描述

大家好，

我在Windows Web服务上遇到问题.尽管我尚未对代码进行任何更改，但最近我一直收到此错误.我正在尝试做的是连接到Web服务并拨打电话并获得响应.因此，如果我可以得到响应，则可以将XML写入字符串.但是现在失败了，直接进入我的catch语句.

奇怪的是，当我将URL放置到浏览器中时，我可以访问XML.

在此之上;
为了拨打电话，我使用的是IDictionary.
代码像这样；

Hello all,

I am facing a problem on a windows web service. Although I havent made any changes on my code, lately I ve been receiving this error. What I am trying to do is connecting to a web service and make a call and get a responce. So if i can get a responce I have a XML written to a string. But now it fails and goes directly to my catch statement.

The weird thing is, I can access the XML when I put the URL to the browser.

In addition to that;
in order to make a call I am using a IDictionary.
the code goes like that;

IDictionary<string, string> r3 = new Dictionary<string, String>();
            r3["Service"] = "ECommerceService";
            r3["Operation"] = "ItemLookup";
            r3["ItemId"] = asin;
            r3["MerchantId"] = "Featured";
            r3["ResponseGroup"] = "Medium,OfferFull,Reviews";

string urlReq = HttpUtility.UrlDecode(r3.Values.ToString());
            requestUrl = helper.Sign(urlReq);

这是行不通的，因为在请求url上它的显示方式为:

-http://onca/xml?AccessKeyId = 0JB3Q7C8ZC0YD8WE7BG2& System.Collections.Generic.Dictionary`2 [System.String，System.String] =& Timestamp = 2011-02-14T19:00:13Z

在此处的链接上，"

This doesnt work because on the request url it apeears as;

- http://onca/xml?AccessKeyId=0JB3Q7C8ZC0YD8WE7BG2&System.Collections.Generic.Dictionary`2[System.String,System.String]=&Timestamp=2011-02-14T19:00:13Z

On the link here "

System.Collections.Generic.Dictionary`2[System.String,System.String]=&

应该有价值.

正确的必须是;

-http://onca/xml?AccessKeyId = 0JB3Q7C8ZC0YD8WE7BG2& ItemId = B000E2EZDM& MerchantId = Featured& Operation = ItemLookup& ResponseGroup = Medium％2COfferFull％2CReviews& amp; amp; amp; amp; amp; amp; 3; Service = AWSTCommerce = 14 br/>
因此，代替"

" there should be values.

The correct must be ;

-http://onca/xml?AccessKeyId=0JB3Q7C8ZC0YD8WE7BG2&ItemId=B000E2EZDM&MerchantId=Featured&Operation=ItemLookup&ResponseGroup=Medium%2COfferFull%2CReviews&Service=AWSECommerceService&Timestamp=2011-02-14T17%3A14%3A25Z&

So instead of "

System.Collections.Generic.Dictionary`2[System.String,System.String]=&

我需要在这里使用"

" i need this there"

&ItemId=B000E2EZDM&MerchantId=Featured&Operation=ItemLookup&ResponseGroup=Medium%2COfferFull%2CReviews&Service=AWSECommerceService&

"

为了得到那个，我怎样才能从IDictionary获得它，有人可以帮忙吗?我也愿意接受新想法吗?

我在想什么，但还没弄清楚；我试过了

"

In order to get that how can I get it from IDictionary like that can someone help? I am open to new ideas as well?

What I am thinking but cant figure out yet; I tried

string urlReq = "";
            foreach (string url in r3.Values)
            {
                urlReq = r3[url] + "&";
            }
            urlReq = urlReq.Substring(0, urlReq.Length - 1);
            urlReq = HttpUtility.UrlDecode(urlReq);

但是这个foreach是错误的.正确的方法是什么?希望我清楚.

谢谢.

But this foreach is faulty. what is the proper way for it? I hope I am clear.

Thanks.

推荐答案

尝试一下:

Try this:

IDictionary<string, string> r3 = new Dictionary<string, string>();
r3["Service"] = "ECommerceService";
r3["Operation"] = "ItemLookup";
r3["ItemId"] = "asin";
r3["MerchantId"] = "Featured";
r3["ResponseGroup"] = "Medium,OfferFull,Reviews";

var urlString = String.Join(string.Empty, r3.Select(it => String.Format("&{0}={1}", it.Key, it.Value)));

urlString 现在将是:& Service = ECommerceService& Operation = ItemLookup& ItemId = asin& MerchantId = Featured& ResponseGroup = Medium，OfferFull，Reviews

urlString will now be: &Service=ECommerceService&Operation=ItemLookup&ItemId=asin&MerchantId=Featured&ResponseGroup=Medium,OfferFull,Reviews
