如何使用Unity在C#中发送HTTP GET和POST请求

我想要的是：

  • 在post请求中发送json数据（我使用Unity序列化程序，所以不需要 新的，我只想在post数据中传递字符串，并且能够 将ContentType设置为application/json）
  • 获得响应代码和正文，无任何问题
  • 在不阻止ui呈现的情况下异步完成所有操作
我所尝试的：

  • 使用HttpWebRequest/HttpWebResponse实现，但是它太难，级别太低（如果我找不到更好的，我就不得不使用它）
  • 使用unity WWW，但它不符合我的要求
  • 使用NuGet-Unity的某些外部软件包不接受它们：(
大多数问题都与线程有关，我在C#中没有足够的经验。
我使用的IDE是Intellij Rider。

使用HttpClient和类似的东西：

public static HttpContent DoPost(object payload, string subPath)
    {
        var httpClient = new HttpClient();

        HttpClient.BaseAddress = new Uri(Global.BaseUrl);
        HttpClient.DefaultRequestHeaders.Clear();
        HttpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); // if you're using json service

        // make request
        var response = Global.HttpClient.PostAsJsonAsync(subPath.TrimLeadingSlash(), payload).Result;

        // check for error
        response.EnsureSuccessStatusCode();

        // return result
        return response.Content;
    }
有效负载是要序列化为json的对象。如果所有请求都指向同一个baseUrl，则可以全局设置HttpClient，并在此处重新使用它

public static HttpContent DoPost(object payload, string subPath)
    {
        var httpClient = new HttpClient();

        HttpClient.BaseAddress = new Uri(Global.BaseUrl);
        HttpClient.DefaultRequestHeaders.Clear();
        HttpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); // if you're using json service

        // make request
        var response = Global.HttpClient.PostAsJsonAsync(subPath.TrimLeadingSlash(), payload).Result;

        // check for error
        response.EnsureSuccessStatusCode();

        // return result
        return response.Content;
    }
有效负载是一个要序列化为json的对象。如果所有请求都指向同一个baseUrl，您可以全局设置HttpClient，并在此处重新使用它。

WWWAPI应该完成这项工作，但
UnityWebRequest
替换了它，因此我将回答更新的API。这非常简单。您必须使用协同程序来完成这项工作，而Unity的API否则，您必须使用C#标准web请求API和线程中的一个。使用协同程序，您可以生成请求，直到完成。这不会阻止主线程或阻止其他脚本运行

注意：

void Start()
{
    StartCoroutine(getRequest("http:///www.yoururl.com"));
}

IEnumerator GetRequest(string uri)
{
    UnityWebRequest uwr = UnityWebRequest.Get(uri);
    yield return uwr.SendWebRequest();

    if (uwr.isNetworkError)
    {
        Debug.Log("Error While Sending: " + uwr.error);
    }
    else
    {
        Debug.Log("Received: " + uwr.downloadHandler.text);
    }
}

void Start()
{
    StartCoroutine(postRequest("http:///www.yoururl.com"));
}

IEnumerator PostRequest(string url)
{
    WWWForm form = new WWWForm();
    form.AddField("myField", "myData");
    form.AddField("Game Name", "Mario Kart");

    UnityWebRequest uwr = UnityWebRequest.Post(url, form);
    yield return uwr.SendWebRequest();

    if (uwr.isNetworkError)
    {
        Debug.Log("Error While Sending: " + uwr.error);
    }
    else
    {
        Debug.Log("Received: " + uwr.downloadHandler.text);
    }
}

 void Start()
 {
     StartCoroutine(postRequest("http:///www.yoururl.com", "your json"));
 }

 IEnumerator PostRequest(string url, string json)
 {
     var uwr = new UnityWebRequest(url, "POST");
     byte[] jsonToSend = new System.Text.UTF8Encoding().GetBytes(json);
     uwr.uploadHandler = (UploadHandler)new UploadHandlerRaw(jsonToSend);
     uwr.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
     uwr.SetRequestHeader("Content-Type", "application/json");

     //Send the request then wait here until it returns
     yield return uwr.SendWebRequest();

     if (uwr.isNetworkError)
     {
         Debug.Log("Error While Sending: " + uwr.error);
     }
     else
     {
         Debug.Log("Received: " + uwr.downloadHandler.text);
     }
 }
对于以下示例，如果您使用的是Unity 2017.2以下的任何内容，请将
SendWebRequest（）
替换为
Send（）
然后将
isNetworkError
替换为
isError
。这将适用于Unity的较低版本。此外，如果您需要以二进制形式访问下载的数据，请将
uwr.downloadHandler.text
替换为
uwr.downloadHandler.data
。最后是
SetRequestHeader
函数is用于设置请求的标头

UnityWebRequest
被实现为在另一个线程中运行。协程用于等待/屈服，等待它完成请求。屈服意味着等待
UnityWebRequest
这是另一个要完成的线程。它没有t在让步时阻塞主线程。这就是为什么协同路由非常棒。我的示例演示了如何
