Unfortunately, writing controllers is very error prone, even for seemingly simple cases.
To work around this, Istio has a variety of abstractions meant to make writing controllers easier.

## Clients

Istio offers a variety of increasingly high level abstractions on top of the common Kubernetes [`client-go`](https://github.com/kubernetes/client-go).

    /**

    protected int pad ( int offset ) {
        int p = offset % getPadding();
        if ( p == 0 ) {
            return 0;

        return getPadding() - p;

`UploadFile` 支持以下 `async` 方法，（使用内部 `SpooledTemporaryFile`）可调用相应的文件方法。

* `write(data)`：把 `data` （`str` 或 `bytes`）写入文件；
* `read(size)`：按指定数量的字节或字符（`size` (`int`)）读取文件内容；
* `seek(offset)`：移动至文件 `offset` （`int`）字节处的位置；
    * 例如，`await myfile.seek(0) ` 移动到文件开头；
    * 执行 `await myfile.read()` 后，需再次读取已读取内容时，这种方法特别好用；
* `close()`：关闭文件。

因为上述方法都是 `async` 方法，要搭配「await」使用。

例如，在 `async` *路径操作函数* 内，要用以下方式读取文件内容：

            this.responseFields = responseFields;
            return this;
        }

        public SearchConditionBuilder offset(final int offset) {
            this.offset = offset;
            return this;
        }

        public SearchConditionBuilder size(final int size) {
            this.size = size;
            return this;
        }

    }

    public int stringWireLength ( String str, int offset ) {
        int len = str.length() + 1;
        if ( this.useUnicode ) {
            len = str.length() * 2 + 2;
            len = ( offset % 2 ) != 0 ? len + 1 : len;
        }
        return len;
    }
