图片服务

1. 获取ossTicket（/solution/community/oss/ticket/get）

2. 使用ossTicket连接OSS服务并上传，返回ossKey；

3. 使用ossKey保存文件，获取uploadId（/solution/community/oss/file/save）

4. 在需要上传文件的API中，使用uploadId作为参数，具体见接口说明。部分仍使用ossKey的接口，将来可能会升级为使用uploadId.

后端上传示例

public static void upload(File file,String host, String dir, String policy, String accessKeyId, String signature)throws ClientProtocolException, IOException{
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        CloseableHttpResponse httpResponse = null;
        RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(200000).setSocketTimeout(200000000).build();
        HttpPost httpPost = newHttpPost(host);
        httpPost.setConfig(requestConfig);
        MultipartEntityBuilder multipartEntityBuilder= MultipartEntityBuilder.create();
        multipartEntityBuilder.setCharset(Charset.forName("UTF-8"));
        multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        //处理文件名乱码
        ContentType contentType = ContentType.create(HTTP.PLAIN_TEXT_TYPE, HTTP.UTF_8);


        multipartEntityBuilder.addTextBody("key",dir+"/" + file.getName(),contentType);
        multipartEntityBuilder.addTextBody("policy",policy);
        multipartEntityBuilder.addTextBody("OSSAccessKeyId",accessKeyId);
        multipartEntityBuilder.addTextBody("success_action_status","200");
        multipartEntityBuilder.addTextBody("callback","");
        multipartEntityBuilder.addTextBody("signature",signature);
        multipartEntityBuilder.addBinaryBody("file",file);


        HttpEntity httpEntity = multipartEntityBuilder.build();
        httpPost.setEntity(httpEntity);


        httpResponse = httpClient.execute(httpPost);
        HttpEntity responseEntity = httpResponse.getEntity();
        int statusCode= httpResponse.getStatusLine().getStatusCode();
        if(statusCode == 200){
            BufferedReader reader = new BufferedReader(new InputStreamReader(responseEntity.getContent()));
            StringBuffer buffer = new StringBuffer();
            String str = "";
            while(!StringUtils.isEmpty(str = reader.readLine())) {
                buffer.append(str);
            }


            System.out.println(buffer.toString());
        }


        httpClient.close();
        if(httpResponse!=null){
            httpResponse.close();
        }
    }

在“获取OSS上传地址”后，完成OSS文件上传，需要一步保存操作，把上传ossKey换成uploadId。

/solution/community/oss/file/save

请求参数

返回结果

注意：这个接口需要和”获取OSS上传地址配合使用。先获取临时区ossTicket，完成文件上传后，调用此接口获取uploadId（上传文件ID）。
