API 网关的body参数如何编码？

1）form形式body的编码

    UrlEncodedFormEntity formEntity = buildFormEntity(bodys);
    if (formEntity != null) {
        post.setEntity(formEntity);
    }

 /**
     * 构建FormEntity
     * 
     * @param formParam
     * @return
     * @throws UnsupportedEncodingException
     */
    private static UrlEncodedFormEntity buildFormEntity(Map<String, String> formParam)
            throws UnsupportedEncodingException {
        if (formParam != null) {
            List<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>();
            for (String key : formParam.keySet()) {
                nameValuePairList.add(new BasicNameValuePair(key, formParam.get(key)));
            }
            UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(nameValuePairList, "UTF-8");
            formEntity.setContentType("application/x-www-form-urlencoded; charset=UTF-8");
            return formEntity;
        }
        return null;
    }

2）非form形式的body

String 形式的body。

if (StringUtils.isNotBlank(body)) {
    post.setEntity(new StringEntity(body, "UTF-8"));
}

byte[]形式的body

if (bodys != null) {
    post.setEntity(new ByteArrayEntity(bodys));
}
