Answer 1

在您的请求中，您需要指定以下字段之一：photo_50 或 photo_100 或 photo_200：

VKRequest yourRequest = VKApi.users().get(VKParameters.from(VKApiConst.FIELDS,"photo_50"))

之后，当您检索用户数据时，您可以获得 photo_50：

yourRequest.executeWithListener(new VKRequest.VKRequestListener() {
@Override
public void onComplete(VKResponse response) {
    super.onComplete(response);

    VKUsersArray usersArray = (VKUsersArray) response.parsedModel;

    for (VKApiUserFull userFull : usersArray) {
          Log.i(TAG, "Avatar image URL: " + userFull.photo_50);            
        }
    }
}

Answer 2

对于安卓应用：

您可以通过发送如下请求来获取个人资料照片：

    https://api.vk.com/method/users.get?user_id=5337911&v=5.23&fields=photo_50

对于 iframe 应用程序：

你应该使用users.get的方法VK.api

    VK.api('users.get', {
        user_ids: id,
        fields: "photo_50"
    }, function(data) {
        photo_50 = data.response[0].photo_50;
    });

如果您不知道是什么，VK.api那么您应该阅读有关Javascript SDK的信息

Answer 3

好吧，我的朋友，我用自己的解决方案解决了这个问题：这适用于 100%

public class RootVKAccount
{
    public List<VKAccount> response { get; set; }
}

[JsonObject("response")]
public class VKAccount
{
    [JsonProperty("photo_200")]
    public string UserImgUrl { get; set; }
}

HttpWebRequest request = WebRequest.Create($@"https://api.vk.com/method/users.get?owner_id={UserId}&fields=photo_200&access_token={Token}&v=5.92") as HttpWebRequest;
    HttpWebResponse respons = request.GetResponse() as HttpWebResponse;

Stream jsonStream = respons.GetResponseStream();
StreamReader r = new StreamReader(jsonStream);
string jsonStr = r.ReadToEnd();
r.Dispose();
var obj = JsonConvert.DeserializeObject<RootVKAccount>(jsonStr);

string uri = obj.response[0].UserImgUrl;
new WebClient().DownloadFile(uri, avatarFullPAth);
