Unity Facebook API - FB.API() Syntax

Question

（使用Unity 5.2.2、Unity Facebook SDK 7.2.2）

我试图在登录后获取我的Facebook个人资料图片，将其设置为Sprite并设置为Image。方法FBLogin（）在单击Button时调用。。

public void FBLogin()
{
    perms = new List<string>() { "public_profile", "email", "user_friends" };
    FB.LogInWithReadPermissions(perms, AuthCallback);
}
private void AuthCallback(ILoginResult result)
{
    if (FB.IsLoggedIn)
    {                
        //Get Facebook Details
        getUserInfoFromFacebook();
    }
    else
    {
        Debug.Log("User cancelled login");
    }
}
private void getUserInfoFromFacebook()
{
    FB.API("/v2.5/me?fields=id,name,picture", Facebook.Unity.HttpMethod.GET, DealWithProfilePicture);
}
private void DealWithProfilePicture(IGraphResult result)
{
    if (result.Error != null)
    {
        Debug.Log("Problem with getting profile picture");
        FB.API("/v2.5/me?fields=id,name,picture",Facebook.Unity.HttpMethod.GET, DealWithProfilePicture);
        Debug.Log(result.Error);
        return;
    }
    profile_picture.sprite = Sprite.Create(result.Texture, new Rect(0,0,128,128), new Vector2(0,0));
}

我根本无法掌握API语法的诀窍——它会产生错误400 Bad Request。有人能帮我学语法吗？

感谢

您可以在该文档中看到，图片不是用户的字段，而是一个额外的边缘，可以通过请求/me/picture:来检索

FB.API("/me/picture",HttpMethod.GET,delegate(IGraphResult result) {
    if (string.IsNullOrEmpty(result.Error))
    {
        Debug.Log("received texture with resolution "+result.Texture.width + "x" + result.Texture.height);
        profile_picture.sprite = Sprite.Create(result.Texture, new Rect(0,0,128,128), new Vector2(0,0));
    }
    else
    {
        Debug.LogWarning("received error="+result.Error);
    }
});
