nginx配置如下:
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,在浏览器中发送请求,chrome控制台显示两个请求。第一个请求是预检,方法是 OPTION 。第二个是真实请求并且有响应,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}}
如上所述,事情是预期的,但我更新了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
{“message”:“验证失败”,“错误”:[[“密钥名称必须为 本 “]]” STATUS_CODE“:422}
XMLHttpRequest无法加载 http://erp.dev.thinkerx.com/api/external/material/catalogs。没有 请求中存在“Access-Control-Allow-Origin”标头 资源。因此,不允许原点“http://localhost”访问。 响应的HTTP状态代码为422。
我有一些问题如下:
答案 0 :(得分:2)
我有同样的问题。问题是nginx仅为200,204,301,302和304状态代码添加标头。
要为每种类型的状态代码获取相同的标题,您必须在add_header指令的末尾添加[always],如下所示。
add_header 'Access-Control-Allow-Origin' $http_origin always;
