与来自nginx的422状态码的响应缺乏“访问控制允许来源”标题

问题描述:

nginx的配置如下:与来自nginx的422状态码的响应缺乏“访问控制允许来源”标题

server { 
      listen 80; 
      listen [::]:80; 

      add_header 'Access-Control-Allow-Origin' $http_origin; 
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, DELETE, PUT, PATCH'; 
      add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range'; 
      add_header 'Access-Control-Max-Age' 1728000; 

      server_name erp.dev.thinkerx.com; 
      access_log /home/thinkerx/nginx/access.log; 
      error_log /home/thinkerx/nginx/error.log; 
      location ~ /.well-known { 
        allow all; 
      } 

      # The rest of your server block 
      root /usr/share/nginx/html/men2017-back-dev/public; 
      index index.html index.htm index.php; 

      location /api/ { 
        try_files $uri $uri/ /index.php$is_args$args; 
      } 

      location ~ \.php$ { 
          try_files $uri /index.php =404; 
          fastcgi_pass 127.0.0.1:9000; 
          fastcgi_index index.php; 
          fastcgi_buffers 16 16k; 
          fastcgi_buffer_size 32k; 
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
          include fastcgi_params; 
        } 
    } 

js代码如下:

$.ajax({ 
    type: 'post', 
    dataType: 'json', 
    contentType: 'application/json; charset=UTF-8', 
    url: "http://erp.dev.thinkerx.com/api/external/material/catalogs", 
    data: JSON.stringify({ 
     domain_id: 2222, 
     code:'X01', 
     name:'123063' 
    }), 
    success: function (response) { 
     console.log(response);  
    }, 
    error: function (xhr, status, error) { 
     console.log(xhr, status, error);  
    }, 
}); 

然后,在发送请求浏览器,Chrome控制台显示两个请求。所述第一请求是预检,方法是OPTION。第二个是真正的请求和响应具有,其状态代码是201 preflight request

{"data":{"id":"16b7d6a0-9eb6-42ca-9ddb-fc61f5e082c0","domain_id":2222,"name":"1230464","code":"X01","parent_id":null,"created_at":1504698369,"updated_at":1504698369}} 

如上,事情的预期,但我更新AJAX数据。

$.ajax({ 
    type: 'post', 
    dataType: 'json', 
    contentType: 'application/json; charset=UTF-8', 
    url: "http://erp.dev.thinkerx.com/api/external/material/catalogs", 
    data: JSON.stringify({ 
     domain_id: 2222, 
     code:'X01', 
     // name:'123063' 
    }), 
    success: function (response) { 
     console.log(response);  
    }, 
    error: function (xhr, status, error) { 
     console.log(xhr, status, error);  
    }, 
}); 

我再次发送请求。偶然发生错误。 also two requests, the second status code is 422

{ “消息”: “验证失败”, “错误”:[[ “键名称必须是 本”]] “STATUS_CODE”:422}

的XMLHttpRequest不能加载 http://erp.dev.thinkerx.com/api/external/material/catalogs 。否 “访问控制 - 允许来源”标题出现在请求的 资源中。因此不允许访问原产地'http://localhost'。 响应了HTTP状态代码422

我有一些问题如下:

  1. 为什么报告同源策略的错误?
  2. 我看到控制台响应,为什么AJAX xhr.responseJSON是不确定的?如何获取响应?

我有同样的问题。问题是nginx仅为200,204,301,302和304状态码添加标题。

要获得相同的头文件对每种类型的状态代码,你必须[总是]添加在这样add_header指令的结束。

add_header 'Access-Control-Allow-Origin' $http_origin always;
