[网络协议]OkHttp3:以map形式传入参数构建post的requestBody

开发中遇到了需要基于okhttp3实现网络请求的需求，第一次用到这个，网上对okhttp的post请求的实现过程不太全面，现以json格式的requestBody为例整理一个完整的post请求

    public Response doPostByParams(String uri, Map parameters) {
        Response response = null;
        String newUrl = sonarServerUrl + uri;
        Map<String, String> httpHeaders = getHeader();
        FormBody.Builder builder = new FormBody.Builder();
        for (String key : parameters.keySet()) {
            builder.add(key, parameters.get(key));
        }
        RequestBody formBody = builder.build();
        Request okRequest = (new Request.Builder())
                .headers(HttpClientHelper.createHeaders(HttpMediaTypeConstant.MEDIA_TYPE_JSON, httpHeaders))
                .url(newUrl).post(formBody).build();

        try {
            response = okHttpClient.newCall(okRequest).execute();

        } catch (IOException ioException) {
            throw new CjjServerException(500, "Sonar Api 请求错误", ioException);
        } finally {
            IOUtils.closeQuietly(response);
        }
    return  response；
    }

以上是基于okhttp3的post的主体方法，其中requestBody构建的主体基于这样一个循环构建：

FormBody.Builder builder = new FormBody.Builder();
for (String key : parameters.keySet()) {
    builder.add(key, parameters.get(key));
}

附周边其他方法：

1.get request header

    private Map<String, String> getHeader() {
        try {
            Map<String, String> httpHeaders = new HashMap<>();

            httpHeaders.put("Authorization",
                    "Basic " + Base64Utils.encodeToString((sonarServerToken + ":").getBytes("US-ASCII")));

            return httpHeaders;
        } catch (Exception e) {
            throw new CjjServerException(500, "Sonar token 设置Header错误", e);
        }
    }
