关于nginx+uWsgi配置遇到的问题

### 1、使uwsgi服务器响应代码大于或等于300的响应重定向到nginx以使用error\_page指令进行处理 ###

uwsgi_intercept_errors  on;

### 2、nginx简单过滤爬虫 ###

#禁止爬虫工具的抓取 
    if ($http_user_agent ~* "python|curl|java|wget|httpclient|okhttp|Scrapy") {
        return 503;
    }
    #禁止指定UA及UA为空的访问 
    if ($http_user_agent ~ "WinHttp|WebZIP|FetchURL|node-superagent|java/|FeedDemon|Jullo|JikeSpider|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|Java|Feedly|Apache-HttpAsyncClient|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms|BOT/0.1|YandexBot|FlightDeckReports|Linguee Bot|^$" ) {  
         return 403;               
    }

### 3、http请求重定向到https ###

#http跳转https
    set $flag 0;
    if ($host = "wxapp.zyqcn.cn") {
      set $flag "${flag}1";
    }
    if ($scheme = "http") {
      set $flag "${flag}2";
    }
    if ($flag = "012") {
      rewrite ^(.*) https://$host$1 permanent;
    }

### 4、将错误页状态码重设为200,并返回指定内容 ###

error_page 502 404 405 500 =200 /error;
    #error最好不要带后缀,之前写了个error.html,然后下面想返回成json,结果各种设置不起作用,后来搞了半天之后才发现是后缀的锅
    location /error {
        default_type application/json;
        #add_header name value always;#always是可选参数,已经存在这个header的情况下使用不会覆盖
        add_header Access-Control-Allow-Origin  *;
     return 200 '{
       "code": 0,"msg":"您的请求暂时无法处理","more": $status}';
    }
