使用Mashape Imgur API上传502 Bad Gateway

Question

我之前正在实施客户端图片上传。代码如下。目前我遇到了以下情况：

public class GlobalConfig {

    @SerializedName("rmhc_config")
    private RMHCConfigModel rmhc;

    public static GlobalConfig fromJson(String json) {
        return new Gson().fromJson(json, GlobalConfig.class);
    }

    public String toJson() {
        return new Gson().toJson(this);
    }

}

public class RMHCConfigModel {

    @SerializedName("show_donation")
    private boolean showDonation;

    @SerializedName("campaignEnabled")
    private boolean campaignEnabled;

}

你知道这可能导致什么吗？
