c#调用百度短网址api

[woodyy]

 byte[] postData = Encoding.UTF8.GetBytes("url=http://bbs.csdn.net/topics/new?forum_id=ASPDotNET");
// byte[] postData = Encoding.UTF8.GetBytes("longurl=http://bbs.csdn.net/topics/new?forum_id=ASPDotNET");
            var url = "http://dwz.cn/create.php";
            var client = new WebClient();
            client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
            client.UploadData(url, "POST", postData);
            byte[] responseData = client.UploadData(url, "POST", postData);
            var r = Encoding.UTF8.GetString(responseData);

最后的r = ‘{"status":-1,"err_msg":"网址不能为空","longurl":""}’

[slwsss]

client.UploadData(url, "POST", postData); 这行去掉

[zfcode]

把http去了试试。。。如下 我这边测试可以了

post地址：http://dwz.cn/create.php

加上请求头:

Host: dwz.cn
Accept: */*
Accept-Language: zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Requested-With: XMLHttpRequest
Pragma: no-cache
Cache-Control: no-cache
Referer: http://dwz.cn/

[娃都会打酱油了]

虽然没用过百度的api 但如果是标准rest格式的话，可以用HttpClient来访问

var httpClient = new HttpClient();
string url;
var dic = new Dictionary<string, string>();
HttpContent httpContent = new FormUrlEncodedContent(dic);
var task=httpClient.PostAsync(url, httpContent);
var responseContent = task.Result.Content

为啥请求之后的长连接只带了一个参数，原本有5个参数

将Url编码以后再传过去就可以了

[by_封爱]

 var data = "url=http://bbs.csdn.net/topics/new?forum_id=ASPDotNET";
 var url = "http://dwz.cn/create.php";
 var client = new System.Net.WebClient(); 
 client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
 var rs = client.UploadString(url, "POST", data);
 Console.WriteLine(rs);

测试可用...另外官方既然提供了方法 我就建议下不要来回的byte[]转换..费劲.

[by_封爱]

另外UploadString(Url, Data);即可 中间的POST不需要也行

[团团美]

data 地址，url里面如果有两个以上参数，生成的短url只有第一个参数。求解

[团团美]

url=http://bbs.csdn.net/topics/new?forum_id=ASPDotNET&bbb=test 生成短url时bbb会消失

[zixiaosy]

对啊 当URL多参数时就会截断生成短网址 求教？？ 如何解决这个问题

[wg5945]

编码一下吧 Uri.EscapeUriString

[hisnowman]

我来回答一下吧，这样处理就对了

url="http://bbs.csdn.net/topics/new?"+Uri.EscapeDataString("forum_id=ASPDotNET&bbb=test");

直接用ajax调用，多方便啊，不用后台代码就可以了。

[範先森]

没用过这个东西，但是代码里面好像有点问题，不知道对不对。 client.UploadData(url, "POST", postData); byte[] responseData = client.UploadData(url, "POST", postData); 这两句是不是重复了

[海宏AA]

我这报错：unsafe url。不知道怎么搞得。代码如下：
public class baiduShortUrl
{ //{"status":0,"tinyurl":"http://dwz.cn/Kod9pTgc","longurl":"http://localhost:7419/PingJia/PingjiaEdit.aspx?sID=SF201806110002","err_msg":""}
public int status = -1;
public string err_msg = "";
public string tinyurl = "";
public string longurl = "";
/// <summary>
/// 短网址
/// </summary>
/// <param name="url"></param>
/// <returns></returns>
public static baiduShortUrl getShortUrl(string url)
{
int n = url.IndexOf('?');
string s = url, s2 = "", rs = "";
if (n > 0)
{ //带参数的处理一下
s = url.Substring(0, n + 1);
s2 = url.Substring(n + 1);
s2 = Uri.EscapeDataString(s2);
s += s2;
}
var creater = "http://dwz.cn/create.php";
var data = "url=" + s; //url,longurl
var client = new System.Net.WebClient();
client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
rs = client.UploadString(creater, "POST", data);
//using (iPublic.iHttpPost poster = new iHttpPost())
//{
// poster.SetFieldValue("url", s);
// poster.Upload(creater, out rs);
//}
//转换
baiduShortUrl bs = JsonConvert.DeserializeObject<baiduShortUrl>(rs);
return bs;
}
public static string getShortUrlStr(string url)
{
baiduShortUrl bs = getShortUrl(url);
if (bs == null || bs.status != 0) return "";
return bs.tinyurl;
}
}
