Question

我仍然是C＃和API的新手。直到昨天我才意识到我没有得到我在回复中期待的所有数据时，我对这个API没有任何问题。

我要做的是调用此API链接以获取JSON响应，然后将其转换为XML并保存文档，这完美但该端点有页面大小限制。

回复中有 odata.nextLink ，但我不知道如何使用它。

我所尝试的是＆＃34;搜索＆＃34;文本字符串＆＃34; odata.nextLink＆＃34;的响应。我能够搜索该字符串并且它给了我所需的值，但是我无法弄清楚如何在do-while循环中使用它来附加每个响应的数据。

非常感谢任何帮助我指向正确方向的帮助。

以下是我正在使用的代码（出于安全原因阻止了Access_Token）

using System;
using System.IO;
using System.Net;
using System.Text;
using System.Xml;
using Newtonsoft.Json;
using RestSharp;

namespace GetProducts
{
    public class WebRequestGet
    {
        public static void Main()
        {
            var client = new RestClient("https://api.channeladvisor.com/v1/Products?access_token=*******************&$select=Sku,ID&$count=true");
            var request = new RestRequest(Method.GET);

            IRestResponse response = client.Execute(request);
            var content = response.Content;

            string json = content;

            XmlDocument doc = (XmlDocument)JsonConvert.DeserializeXmlNode(json, "Channeladvisor");

            doc.Save(@"C:\Users\NHead\Documents\Visual Studio 2015\Projects\GetProducts\GetProducts\bin\Debug\Response.xml");

            Console.WriteLine(content);
            Console.ReadLine();
        }
    }
}

这是我在转换为XML之前得到的响应。

我认为这可能会对你有所帮助

public static void Main()
{
    do
    {
        var client = new RestClient("https://api.channeladvisor.com/v1/Products?access_token=*******************&$select=Sku,ID&$count=true");
        var request = new RestRequest(Method.GET);

        IRestResponse response = client.Execute(request);
        var content = response.Content;

        string json = content;
    }
    while(content.Contains("odata.nextLink"))
    //rest of your code
}

但是这里的情况是你需要读取nextLink的值。因此你可以使用Newtonsoft来阅读它。但我在这里指出的一点是，在nextLink中，它只是在URL的末尾添加了$skip=100。所以我假设如果你有更多的数据，它下次会添加$skip=200因此你可以有一个解决方法而不创建类来读取完整的JSON

public static void Main()
{
    string myUrl = "https://api.channeladvisor.com/v1/Products?access_token=*******************&$select=Sku,ID&$count=true";
    int cntskip = 0;
    do
    {
        if(cntskip>0)
        {
            myUrl += "$skip=" + cntskip;
        }
        var client = new RestClient(myUrl);
        var request = new RestRequest(Method.GET);

        IRestResponse response = client.Execute(request);
        var content = response.Content;

        string json = content;
        cntskip += 100;
    }
    while(content.Contains("odata.nextLink"))
    //rest of your code
}

c＃RestSharp odata.nextLink JSON响应
