Hi Jim,
這是我申請 Apple 開發者帳號最後的進度情況
網頁截圖如下所示請看 Authority to Sign Legal Agreements 的部分
Apple 會用 mail 或是 電話 跟您作聯繫
來確認是否您授權我 Jeffrey 來替公司的 CEO 也就是您做這樣的申請動作希望一切順利

Hi Jeffrey,
也 再麻煩你把一些相關iOS申 請的進度跟Jim 分 享一下.
這 樣Apple 來 電時, Jim 可 知道要回應甚麼. 或 有甚麼相關訊息這樣.
Thank you.

- 快速通用网关接口（Fast Common Gateway Interface／FastCGI）是通用网关接口（CGI）的改进，描述了客户端和服务器程序之间传输数据的一种标准。
- FastCGI致力于减少Web服务器与CGI程式之间互动的开销，从而使服务器可以同时处理更多的Web请求。
- 与为每个请求创建一个新的进程不同，FastCGI使用持续的进程来处理一连串的请求。
- 这些进程由FastCGI进程管理器管理，而不是web服务器。
- 当进来一个请求时，Web 服务器把环境变量和这个页面请求通过一个unix domain socket(都位于同一物理服务器）或者一个IP Socket（FastCGI部署在其它物理服务器）传递给FastCGI进程。
- 由于 FastCGI 程序并不需要不断的产生新进程，可以大大降低服务器的压力并且产生较高的应用效率。它的速度效率最少要比CGI 技术提高 5 倍以上。
- 它还支持分布式的部署， 即 FastCGI 程序可以在web 服务器以外的主机上执行。
- spawn-fcgi是一个通用的FastCGI进程管理器，简单小巧，原先是属于lighttpd的一部分，后来由于使用比较广泛，所以就迁移出来作为独立项目了。
- CGI 就是所谓的短生存期应用程序，FastCGI 就是所谓的长生存期应用程序。
- FastCGI像是一个常驻(long-live)型的CGI，它可以一直执行着，不会每次都要花费时间去fork一次(这是CGI最为人诟病的fork-and-execute 模式)。
-
nginx 不能像apache那样直接执行外部可执行程序，但nginx可以作为代理服务器，将请求转发给后端服务器，这也是nginx的主要作用之一。
-
其中nginx就支持FastCGI代理，接收客户端的请求，然后将请求转发给后端fastcgi进程。
-
下面介绍如何使用C/C++编写cgi/fastcgi，并部署到nginx中。
-
通过前面的介绍知道，fastcgi进程由FastCGI进程管理器管理，而不是nginx。这样就需要一个FastCGI管理，管理我们编写fastcgi程序。
-
本文使用spawn-fcgi作为FastCGI进程管理器。
-
spawn-fcgi是一个通用的FastCGI进程管理器，简单小巧，原先是属于lighttpd的一部分，后来由于使用比较广泛，所以就迁移出来作为独立项目了。
-
spawn-fcgi使用pre-fork 模型，功能主要是打开监听端口，绑定地址，然后fork-and-exec创建我们编写的fastcgi应用程序进程，退出完成工作。
-
fastcgi应用程序初始化，然后进入死循环侦听socket的连接请求。
安装spawn-fcgi ???
openWrt 上安裝 spawn-fcgi ???
在 OpenWrt 上做了 opkg update 後然後下了 opkg list... 8xxx 行

進度超順利... opkg... 真可怕
我竟然今天才知道它有多好用
Example 1: TinyFastCGI
Here is a simple example of a responder FastCGI application written in C:
#include "fcgi_stdio.h" /* fcgi library; put it first*/
#include <stdlib.h>
int count;
void initialize(void) {
count=0;
}
void main(void) {
/* Initialization. */
initialize();
/* Response loop. */
while (FCGI_Accept() >= 0) {
printf("Content-type: text/html\r\n"
"\r\n"
"<title>FastCGI Hello! (C, fcgi_stdio library)</title>"
"<h1>FastCGI Hello! (C, fcgi_stdio library)</h1>"
"Request number %d running on host <i>%s</i>\n",
++count, getenv("SERVER_HOSTNAME"));
}
}存成 tinyFastCGI.c

Setting Up FastCGI Proxying
nginx can be used to route requests to FastCGI servers which run applications built with various frameworks and programming languages such as PHP.
The most basic nginx configuration to work with a FastCGI server includes using the fastcgi_pass directive instead of the proxy_pass directive, and fastcgi_param directives to set parameters passed to a FastCGI server.
Suppose the FastCGI server is accessible on localhost:9000. Taking the proxy configuration from the previous section as a basis, replace the proxy_pass directive with the fastcgi_pass directive and change the parameter to localhost:9000.
In PHP, the SCRIPT_FILENAME parameter is used for determining the script name, and the QUERY_STRING parameter is used to pass request parameters.
The resulting configuration would be:
check 一下目前的 nginx.conf
root@JoySince:/etc/nginx# cat /etc/nginx/nginx.conf
user nobody nogroup;
worker_processes 1;
events {
worker_connections 1024;
}

感動的瞬間
趕緊記錄一下

走到這一部可不容易
- 開發環境要做
make menuconfig將 fcgi build 進去 - JS9331 板子上利用 opkg 裝了
- nginx
- spawn-fcgi
感謝這一篇 Writing Hello World in FCGI with C++
試著從 tinyFastCGI.c 出發
首先想辦法解析 POST 的參數
耐著性子從 header 檔出發
來掃一下有哪些 header 可以用
卡在 getenv("QUERY_STRING") 總是回應 NULL
- fcgitest.c
#include "fcgiapp.h"
#include <stdlib.h>
#include <string.h>
int main () {
FCGX_Stream *in, *out, *err;
FCGX_ParamArray envp;
while (FCGX_Accept(&in, &out, &err, &envp) >= 0) {
char *method = FCGX_GetParam("REQUEST_METHOD", envp);
FCGX_FPrintF(out,
"Content-type: text/html\r\n"
"\r\n"
"<h1>fastCGI Test</h1>"
);
if (!method) {
FCGX_FPrintF(out,
"FCGX_GetParam(\"REQUEST_METHOD\", envp);"
" NULL"
);
}
}
return 0;
}還是 NULL
看來要從 nginx 查起
找到了
/etc/nginx/nginx.conf
events {
worker_connections 1024;
}
http {
server {
listen 8080;
server_name localhost;
location / {
fastcgi_pass 127.0.0.1:8000;
include fastcgi_params;
}
}
}
關鍵就是 include fastcgi_params;
沒有 fastcgi_params 竟然萬萬不行
/etc/nginx/fastcgi_params
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param HTTPS $https if_not_empty;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;

}動起來囉
