ngx.req.set_uri_args -------------------- **语法:** *ngx.req.set_uri_args(args)* **环境:** *set_by_lua*\**, rewrite_by_lua*\**, access_by_lua*\**, content_by_lua*\**, header_filter_by_lua*\**, body_filter_by_lua*\* 用 `args` 参数重写当前请求的 URI 请求参数。`args` 参数可以是一个 Lua 字符串，比如 ```lua ngx.req.set_uri_args("a=3&b=hello%20world") ``` 或一个包含请求参数 key-value 对的 Lua table，例如 ```lua ngx.req.set_uri_args({ a = 3, b = "hello world" }) ``` 在第二种情况下，本方法将根据 URI 转义规则转义参数的 key 和 value。 本方法也支持多值参数： ```lua ngx.req.set_uri_args({ a = 3, b = {5, 6} }) ``` 此时请求参数字符串为 `a=3&b=5&b=6`。 这个方法在 `v0.3.1rc13` 版本中首次引入。 更多用法请参考 [ngx.req.set_uri](#ngxreqset_uri)。 > English Source **syntax:** *ngx.req.set_uri_args(args)* **context:** *set_by_lua*\**, rewrite_by_lua*\**, access_by_lua*\**, content_by_lua*\**, header_filter_by_lua*\**, body_filter_by_lua*\* Rewrite the current request's URI query arguments by the `args` argument. The `args` argument can be either a Lua string, as in ```lua ngx.req.set_uri_args("a=3&b=hello%20world") ``` or a Lua table holding the query arguments' key-value pairs, as in ```lua ngx.req.set_uri_args({ a = 3, b = "hello world" }) ``` where in the latter case, this method will escape argument keys and values according to the URI escaping rule. Multi-value arguments are also supported: ```lua ngx.req.set_uri_args({ a = 3, b = {5, 6} }) ``` which will result in a query string like `a=3&b=5&b=6`. This interface was first introduced in the `v0.3.1rc13` release. See also [ngx.req.set_uri](#ngxreqset_uri). [返回目录](#nginx-api-for-lua)
