        String imageURL = null;
        try {
            String token = this.getToken();
            imageURL = this.uploadImage(token, image.getBytes());

        } catch (Exception e) {
            throw new RuntimeException(e);
        }
        return imageURL;
    }

    /**
     * 上传图片
     *
     * @param accessToken
     * @param imageBytes
     * @return
     * @throws Exception
     */
    public String uploadImage(String accessToken, byte[] imageBytes) throws Exception {
        String url = String.format("https://api.weixin.qq.com/cgi-bin/media/uploadimg?access_token=%s", accessToken);
        OkHttpClient client = new OkHttpClient();
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("media", "image.jpg",
                        RequestBody.create(MediaType.parse("image/jpg"), imageBytes))
                .build();
        Request request = new Request.Builder()
                .url(url)
                .post(requestBody)
                .build();
        Response response = client.newCall(request).execute();
        if (response.isSuccessful()) {
            String result = response.body().string();
            JSONObject jsonObject = JSONObject.parseObject(result);
            String imageURL = jsonObject.getString("url");
            return imageURL;
        } else {
            throw new Exception("请求未成功,错误代码:" + response.code());
        }
    }

3、使用postMan测试

4、可以看到 返回了图片链接；ok啦 至此接口就掉通啦～
