为 System.Net.HttpClient 构建查询字符串获取 [英] Build query string for System.Net.HttpClient get

问题描述

如果我想使用 System.Net.HttpClient 提交一个 http get 请求，似乎没有添加参数的 api，这是正确的吗?

If I wish to submit a http get request using System.Net.HttpClient there seems to be no api to add parameters, is this correct?

是否有任何简单的 api 可用于构建不涉及构建名称值集合和 url 编码的查询字符串，然后最终连接它们?我希望使用类似 RestSharp 的 api(即 AddParameter(..))

Is there any simple api available to build the query string that doesn't involve building a name value collection and url encoding those and then finally concatenating them? I was hoping to use something like RestSharp's api (i.e AddParameter(..))

是的.

当然:

var query = HttpUtility.ParseQueryString(string.Empty);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
string queryString = query.ToString();

会给你预期的结果:

foo=bar%3c%3e%26-baz&bar=bazinga

您可能还会发现 UriBuilder 类很有用:

You might also find the UriBuilder class useful:

var builder = new UriBuilder("http://example.com");
builder.Port = -1;
var query = HttpUtility.ParseQueryString(builder.Query);
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
builder.Query = query.ToString();
string url = builder.ToString();

会给你预期的结果:

http://example.com/?foo=bar%3c%3e%26-baz&bar=bazinga

您可以更安全地提供给您的 HttpClient.GetAsync 方法.

that you could more than safely feed to your HttpClient.GetAsync method.
