C#实现中国天气网JSON接口测试

接上一篇,经过反复的查看,最终从这篇文章中找到了一个可用的JSON接口,于是研究了一下中国天气网JSON接口的测试:

和上一篇XML接口测试的原理是一样的,只是需要安装一下Newtonsoft.Json:

这个就是传说中的JSON.Net!在项目右键点击“管理NuGet程序包”中搜索json.net然后安装即可,等到项目的引用中出现这个东西的时候就可以在程序里using Newtonsoft.Json了。

还是老套路,不管有用没用,先把接口返回的JSON内容保存到本地一份。这里为了查看方便我直接在控制台打印出来了,方便查看JSON的结构并加以分析:

通过JSON.Net对字符串进行反序列化(也可以强转),然后对内容加以分析即可,至于想测试,一般是比较值。这里就做一次遍历,不做比较了。代码如下:

using System;
using System.Text;
using Newtonsoft.Json;
using System.Net;
using System.IO;
using Newtonsoft.Json.Linq; namespace JsonInterfaceTest
{
class Program
{
static void Main(string[] args)
{
test();
} private static void test(int interfaceNumber)
{
string url = "http://www.weather.com.cn/adat/cityinfo/" + interfaceNumber + ".html";
string localContent = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + @"\test.txt";
try
{
WebClient MyWebClient = new WebClient();
Byte[] pageData = MyWebClient.DownloadData(url);
string pageHtml = Encoding.UTF8.GetString(pageData);
using (StreamWriter sw = new StreamWriter(localContent))
{
sw.WriteLine(pageHtml);
}
//JObject jObj = JObject.Parse(pageHtml);
JObject jObj = JsonConvert.DeserializeObject(pageHtml) as JObject;
Console.WriteLine(jObj.ToString());
ReadJson(jObj);
Console.ReadLine();
}
catch (WebException webEx)
{
Console.WriteLine(webEx.Message.ToString());
}
} private static void ReadJson(JObject jObj)
{
foreach (var o in jObj)
{
Console.Write(o.Key+":");
if (o.Value is JObject)
{
Console.WriteLine();
ReadJson(JsonConvert.DeserializeObject(o.Value.ToString()) as JObject);
}
else
{
Console.WriteLine(o.Value);
}
}
}
}
}

换汤不换药,稍微改一下上面的接口测试程序就可以通过快递接口查快递了(通过快递公司代号和快递单号):

using System;
using System.Text;
using Newtonsoft.Json;
using System.Net;
using System.IO;
using Newtonsoft.Json.Linq; namespace JsonInterfaceTest
{
class Program
{
static void Main(string[] args)
{
test("zhongtong", );
Console.Read();
} private static void test(string a, long b)
{
string url = "http://www.kuaidi100.com/query?type=" + a + "&postid=" + b;
string localContent = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + @"\test.txt";
try
{
WebClient MyWebClient = new WebClient();
Byte[] pageData = MyWebClient.DownloadData(url);
string pageHtml = Encoding.UTF8.GetString(pageData);
using (StreamWriter sw = new StreamWriter(localContent))
{
sw.WriteLine(pageHtml);
}
JObject jObj = JObject.Parse(pageHtml);
//JObject jObj = JsonConvert.DeserializeObject(pageHtml) as JObject;
Console.WriteLine(jObj.ToString());
ReadJson(jObj);
Console.ReadLine();
}
catch (WebException webEx)
{
Console.WriteLine(webEx.Message.ToString());
}
} private static void ReadJson(JObject jObj)
{
foreach (var o in jObj)
{
Console.Write(o.Key + ":");
if (o.Value is JObject)
{
Console.WriteLine();
ReadJson(JsonConvert.DeserializeObject(o.Value.ToString()) as JObject);
}
else
{
Console.WriteLine(o.Value);
}
}
}
}
}

其实用PowerShell脚本来完成这个测试是更加方便的!微软给我们提供了很方便的“ConvertFrom-Json”这一cmdlet来实现我们对Json对象的交互!代码如下:

function test()
{
param($interfaceNumber)
$url = "http://www.weather.com.cn/adat/cityinfo/" + $interfaceNumber + ".html";
$jsonObject = Invoke-WebRequest -Uri $url | %{$_.Content} | ConvertFrom-Json
if($jsonObject.weatherinfo.img1 -eq "d1.gif"){Write-Host "Test pass!" -ForegroundColor Green}
}
test -interfaceNumber 101010100

调用脚本执行效果如下:
