background analysis
EasyNVR recent use of the process, many small consulting partners on the issue of interface calls, the initial judgment should be experiencing a permissions problem (401 Unauthorized) . EasyNVR provides a standard API interface for third-party systems and applications, to facilitate docking second development is exclusively their own business Internet broadcast platform. Interface definitions are generally divided into an interface and the interface caller may define a predetermined parameter and return type of the received form, and the interface is defined only by full access according to predetermined parameters by the interface definition. We are talking about is called webService (network service).
This post will be explained based on the problem of the interface calls itself a call to EasyNVR interface and some feedback of users:
Interface Overview
API style using Restful Http protocol, all requests use Get / Post embodiment, are case-insensitive. The basic structure is as follows:
http://<IP>:<Port>/api/<Version>/<Action>?<Param1>=<value>&<Param2>=<Value>&.....
parameter
| parameter name | definition | Explanation |
| IP | Platform Address | IP addresses |
| Port | Platform Port | Communication Port |
| Version | API Version | API version |
| Action | Action | Operations performed |
| Param | Action Parameter | Operation parameters used, there may be a plurality of parameters, each corresponding to a Value. |
| Value | Parameter Value | Parameter values, if the special characters such as & appear in a string Value, it must be "" Value wrap. |
return value
API call will return Json string representing the results of the operation to return
{
"EasyDarwin" : {
"Body" : {
……
},
"Header" : {
"CSeq" : "1",
"ErrorNum" : "200",
"ErrorString" : "Success OK",
"MessageType" : "MSG_SC_API_ACK",
"Version" : "1.0"
}
}
}
Call interface
Many small partners to focus only on functional interface, often direct mass participation tune the interface, so it was an error opening the 401; the easiest way is, after we get the interface documentation, you can read the document, be aware of;
First performed before calling the interface simple explanation: EasyNVR Most call interface information required to carry token in a cookie; for this token information, login through the interface is returned. When we successfully request Interface: When "? / Api / v1 / login username = xxx & password = xxx", returns a token information;
{
"EasyDarwin" : {
"Body" : {
"Token" : "a19cb5f6e7d2449d8d24c8a0fc554ca7"
},
"Header" : {
"CSeq" : "1",
"ErrorNum" : "200",
"ErrorString" : "Success OK",
"MessageType" : "MSG_SC_SERVER_LOGIN_ACK",
"Version" : "1.0"
}
}
}
We get a cookie on the token to store information. 401 appeared, in most cases is a cookie tooken carry, error interface format, send the wrong parameters.
Tips: Some big brother when requesting login interfaces found 401 rights restrictions appear; the interface through the MD5 password is encrypted. In the cookie request headers carries corresponding tooken other interfaces requests during a request.
Examples are shown below:
First introduced jqueryCookie, used to set the cookie (if there are other ways to set cookie can not quote)
<script src="/adminlte-2.3.6/plugins/cookie/jquery.cookie.min.js"></script>
Request to the interface card via ajax
- In the absence of call interface settings
$.ajax({
type: "GET",
url: "api/v1/login",
data: {
username: username,
password: password
},
global: false,
success: function(data) {
try {
var ret = JSON.parse(data);
var token = ret.EasyDarwin.Body.Token;
$.cookie("token", token);
//将tooken设置进cookie中
$.cookie("username", username);
} catch (e) {
console.log(e);
}
},
After successfully processing a request via ajax the obtained data, a cookie will tooken out:
- Call Interface and cookie settings:
At this time when we request other interfaces, you will find there is cookie tooken in the request header, and can be successfully request interface.
