php发布请求--data

问题描述：

I try to make a request from my php code to another remote server which has Riak DB running. I need to make a map-reduce request so I have to do it with POST http.

Riak documentation says (for e.g.)

curl -XPOST http://`localhost`:8091/mapred \
-H 'Content-Type: application/json' \
-d '{
"inputs":"training",
"query":[{"map":{"language":"javascript",
"source":"function(riakObject) {
var m = riakObject.values[0].data.match(/pizza/g);
return [[riakObject.key, (m ? m.length : 0 )]];
}"}}]}'

How to do the same with PHP?

我尝试从我的php代码向另一个运行Riak DB的远程服务器发出请求。我需要制作一个map-reduce请求，所以我必须使用POST http。 p>

Riak文档说（例如） p>

  curl -XPOST http：//`localhost`：8091 / mapred \
H'Content-Type：application / json'\
d'{
“inputs”：“training”，
“query”：[{  “map”：{“language”：“javascript”，
“source”：“function（riakObject）{
var m = riakObject.values [0] .data.match（/ pizza / g）; 
return [[  riakObject.key，（m？m.length：0）]]; 
}“}}]}'
  code>  pre> 
 
 如何用PHP做同样的事情？   p>

答

http://php.net/manual/en/book.curl.php

You can use the PHP cUrl library for this. Be sure to enable it in the PHP modules.

Edit:

the --data flag tells cUrl to use POST, this is the PHP variant

curl_setopt($ch, CURLOPT_POST,           TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS,     $body)

Where the body variable can be the data, for example JSon.
