C# UnityWebRequest已发送错误

每当我试图将unity中的数据发送到我的php文件时，这两个错误就会不断出现。我尝试了所有我能找到的关于“curl error 51”的修复方法，所以我假设主要问题是第二个错误

Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED

我已尝试查找此错误，但找不到任何答案

InvalidOperationException: UnityWebRequest has already been sent; cannot begin sending the request again
UnityEngine.Networking.UnityWebRequest.SendWebRequest () (at <2424cac47b134bcb9980d5fdf8ea4441>:0)

正如错误消息所说，WebRequest太多了

而不是

IEnumerator Register()
{
    WWWForm form = new WWWForm();
    form.AddField("name", "nameField.text");

    using (UnityWebRequest www = UnityWebRequest.Post("https://localhost/sqlconnect/addscore.php", form))
    {
        yield return www.SendWebRequest();

        {
            yield return www.SendWebRequest();

            if (www.isNetworkError || www.isHttpError)
            {
                Debug.Log(www.error);
            }
            else
            {
                Debug.Log("Form upload complete!");
                UnityEngine.SceneManagement.SceneManager.LoadScene(0);
            }

返回www.SendWebRequest；在代码中出现两次。正如错误所说，您只需要一个。我假设UNITYTLS_X509; Verify_FLAG_NOT_TRUSTED错误是因为您正在使用https和自签名证书或其他导致其不受信任的内容。也许可以先尝试http，将问题缩小到您的代码或配置；{yield return www.SendWebRequest；然后您需要一个https证书处理程序！请参阅这是否回答了您的问题？；这看起来很像是一个基于打字错误/意外事件的问题，因此脱离主题，因为它在将来不会真正帮助其他人

IEnumerator Register()
{
    WWWForm form = new WWWForm();
    form.AddField("name", "nameField.text");

    using (UnityWebRequest www = UnityWebRequest.Post("https://localhost/sqlconnect/addscore.php", form))
    {
        yield return www.SendWebRequest();

        {
            yield return www.SendWebRequest();

            if (www.isNetworkError || www.isHttpError)
            {
                Debug.Log(www.error);
            }
            else
            {
                Debug.Log("Form upload complete!");
                UnityEngine.SceneManagement.SceneManager.LoadScene(0);
            }
