How to use PHP to transmit data to remote via http url. Thanks.-PHP Chinese Network Q&A

Now there is a project where Party A has given an http interface as follows

1. Provide interface http access url, uniform character encoding: UTF-8.

2. http interface request content-Type="application/json".

3. The interface requests the interface url through http post and sends a body that conforms to the JSON specification.

The access key is also given, how to implement it using PHP. Thanks.

Request example:

{

"secretKey": "**********",

"stationNo": "123456789",

"msgId": "1111",

"data": {

"heatMeter": [

"installAddr": "1# Heat Meter",

"readTime": ""2017-09-25 12:00:01",

"accHeat": 11.12,

"accCold": 11.13,

"accFlow": 11.14,

## "" Coldunit ":" gj ",

" Powerunit ":" gj/h " ,
