假设您有一个函数返回postgresQL数据库中定义的json。
CREATE OR REPLACE FUNCTION test() RETURNS JSON AS $$
SELECT
'[
{"fName":"John","lName":"Doe"},
{"fName":"Jane","lName":"Doe"}
]'::JSON;
$$
LANGUAGE SQL STRICT IMMUTABLE;
SELECT test();
-------------------------------------
[
{"fName":"John","lName":"Doe"},
{"fName":"Jane","lName":"Doe"}
]
此外你有一个包含Postgres Nginx模块的Nginx(openresty) 使用以下配置文件:
worker_processes 1;
error_log logs/error.log;
events {
worker_connections 1024;
}
http {
upstream database {
postgres_server localhost dbname=example user=postgres;
postgres_keepalive max=200 overflow=reject;
}
server {
listen 8080;
location /test/ {
postgres_pass database;
rds_json on;
postgres_query HEAD GET "SELECT test()";
postgres_rewrite HEAD GET no_rows 410;
}
}
}
rds_json on; 所有引号都在输出中转义,如下所示:
curl http://localhost:8080/test/
[{"test":"[\n {\"fName\":\"John\",\"lName\":\"Doe\"},\n {\"fName\":\"Jane\",\"lName\":\"Doe\"}\n ]"}]
如果我将 rds_json设置为关闭; 我收到格式正确的json,但返回字符串以一些尴尬的标志开始和结束:
@^C^@^@^@^@^@^@^B^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^A^@^@<80>r^@^D^@test^AL^@^@^@[
{"fName":"John","lName":"Doe"},
{"fName":"Jane","lName":"Doe"}
]^@
有没有办法在结果对象中删除其他符号,或者在第一种情况下没有转义所有双引号?

答案 0 :(得分:0)
我找到了一个理由。实际上它是微不足道的。而不是将openresty格式化输出到json。对不起,我的问题打扰了社区。 我必须正确设置标题:
worker_processes 1;
error_log logs/error.log;
events {
worker_connections 1024;
}
http {
upstream database {
postgres_server localhost dbname=example user=postgres;
postgres_keepalive max=200 overflow=reject;
}
server {
listen 8080;
location /test/ {
postgres_pass database;
postgres_query HEAD GET "SELECT test()";
more_set_headers 'Content-Type: application/json';
postgres_rewrite HEAD GET no_rows 410;
}
}
}
