.Net Core 集成onlyOffice问题记录

1. 切换了文档保存的回调地址callbackUrl，一直无法调用，查询日志发现http方法不对，改.net api 为HttpPost 后可以进行访问
2. onlyoffice 默认日志位置：/var/log/onlyoffice/

3. .net Core 读取document回调地址传递过来的参数时, 需如下读取：

   using (var receiveStream = Request.Body)
            {
                using (var readStream = new StreamReader(receiveStream))
                {
                    body = await readStream.ReadToEndAsync();
                    if (string.IsNullOrEmpty(body))
                    {
                        faildString = "{\"error\":1,\"message\":\"Request stream is empty\"}";
                    }
                }
            }

   .net core 3 之后，需要使用ReadToEndAsync();

4. 打开PPT一直报错，提示文件无法打开，原因：PPT必须有一个页面，不然是0KB无法打开

5. wasm streaming compile failed: TypeError: Failed to execute ‘compile’ on ‘We

解决方案：打开nginx config目录下的mime.types文件，在types中添加application/wasm wasm;并且执行 nginx -s reload

1. linux时区同步：timedatectl set-timezone Asia/Shanghai ：https://www.cnblogs.com/bpzblog/p/13931829.html 更改语言
2. postgre时区：https://www.cnblogs.com/liangping/p/7610588.html

3. onlyoffice 跨域：需配置：ds-docservice.conf nginx.conf —-好像不是必须，需要.Net设置跨域

   if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        #
        # 自定义标题和标题各种浏览器*应该*可以，但不是
        #
        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
        #
        # 告诉客户这个飞行前信息有效期为20天
        #
        add_header 'Access-Control-Max-Age' 1728000;
        add_header 'Content-Type' 'text/plain; charset=utf-8';
        add_header 'Content-Length' 0;
        return 204;
     }
     if ($request_method = 'POST') {
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
        add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
     }
     if ($request_method = 'GET') {
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
        add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
     }
