安諾尼實時頻譜儀如何使用MATLAB進行二次研發(1)
1、如何建立與Matlab的實時HTTP連接
安諾尼RTSA-Suite PRO實時頻譜儀軟件提供了一個支持JSON數據格式，強大的HTTP服務器模塊，使用它的RESTful web service建立一個與Matlab的實時HTTP連接是非常簡單的。
示例請參考：https://de.mathworks.com/help/matlab/ref/webread.html
2、如何從服務器轉換JSON文本的其他信息？
參考示例：
https://de.mathworks.com/help/compiler_sdk/mps_dev_test/mps.json.decoderesponse.html?searchHighlight=json&s_tid=srchtitle#d123e13998
mps.json.decoderesponse
Convert JSON text from a server response to MATLAB data
Syntax
lhs = mps.json.decoderesponse(response)
error = mps.json.decoderesponse(response)
Description
lhs = mps.json.decoderesponse(response) reads the JSON payload of the output arguments returned from a successful MATLAB® function call.
error = mps.json.decoderesponse(response) reads the JSON payload of the MATLAB error thrown from a failed MATLAB function call.
Examples
>Read from MATLAB Production Server Payload
mps.json.decoderesponse('{"lhs":[[[1, 2, 3, 4]]]}')
ans =
1x1 cell array
{1x4 double}
Read response from a sortstudent function deployed on MATLAB Production Server
Execute mps.json.encoderequest and mps.json.decoderesponse to call a function deployed on MATLAB Production Server™ using webwrite. In this case, student names and their corresponding scores are deployed to MATLAB Production Server to the sortstudents function that sorts students based on their scores. The result returned is the equivalent to calling the function sortstudents(struct('name', 'Ed', 'score', 83), struct('name', 'Toni', 'score', 91)) from MATLAB.
Assume that there is a deployable archive studentapp that contains a MATLAB function sortstudents deployed to the server.
data = {struct('name', 'Ed', 'score', 83), struct('name', 'Toni', 'score', 91)};
body = mps.json.encoderequest(data);
options = weboptions;
% Create a weboptions object that instructs webread to return JSON text
options.ContentType = 'text';
% Create a weboptions object that instructs webwrite to encode character vector data as JSON to post it to a web service
options.MediaType = 'application/json';
response = webwrite('http://localhost:9910/studentapp/sortstudents', body, options);
result = mps.json.decoderesponse(response);
Input Arguments
response — JSON result from a MATLAB function call
char (default)
JSON result from a MATLAB function call specified as JSON text.
Output Arguments
lhs — Cell vector of output arguments
Cell vector
Cell vector of output arguments that are from a MATLAB function called from MATLAB Production Server.
error — Generated output when request results in a MATLAB error
struct array
Generated output when request to MATLAB function called from MATLAB Production Server results in a MATLAB error returned as a struct array.
Version History
Introduced in R2018a
