One way would be to use the Get Filekeyword from the OperatingSystemlibrary, and then use the built-in Evaluatekeyword to convert it to a python object.
一种方法是使用OperatingSystem库中的Get File关键字，然后使用内置的Evaluate关键字将其转换为 python 对象。
For example, consider a file named example.json with the following contents:
例如，考虑一个名为 example.json 的文件，其内容如下：
{
"firstname": "Inigo",
"lastname": "Montoya"
}
You can log the name with something like this:
您可以使用以下内容记录名称：
*** Settings ***
| Library | OperatingSystem
*** Test Cases ***
| Example of how to load JSON
| | # read the raw data
| | ${json}= | Get file | example.json
| |
| | # convert the data to a python object
| | ${object}= | Evaluate | json.loads('''${json}''') | json
| |
| | # log the data
| | log | Hello, my name is ${object["firstname"]} ${object["lastname"]} | WARN
Of course, you could also write your own library in python to create a keyword that does the same thing.
当然，你也可以用python编写自己的库来创建一个做同样事情的关键字。

There is a library available for this: HttpLibrary.HTTP
有一个可用的库：HttpLibrary.HTTP
${json}= | Get file | example.json
${port} | HttpLibrary.HTTP.Get Json Value | ${json} | /port
log | ${port}
API Document is available here: http://peritus.github.io/robotframework-httplibrary/HttpLibrary.html
API 文档可在此处获得：http: //peritus.github.io/robotframework-httplibrary/HttpLibrary.html

A common use is passingthe json data to another library like Http Library Requests. You could do:
一个常见的用途是将json 数据传递给另一个库，如Http Library Requests。你可以这样做：
*** Settings ***
Library OperatingSystem
Library RequestsLibrary
*** Test Cases ****
Create User
#...
${file_data}=
... Get Binary File ${RESOURCES}${/}normal_user.json
Post Request example_session /user data=${file_data}
#...
No direct python involved and no intermediary json object.
不涉及直接的 python，也没有中间的 json 对象。

Thanks Vinay .. that helped now we can retrieve data from json file in robot framework as well
*** Settings ***
Library HttpLibrary.HTTP
Library OperatingSystem
*** Test Cases ***
Login_to_SalesForce_Json
${jsonfile} Get File c:/pathtojason/Data/testsuite.json
${username} Get Json Value ${jsonfile} /test_case1/username
log ${username}
Below is the json file structure
{
"test_case1":
{
"username":"User1",
"password":"Pass1"
}
,
"test_case2":
{
"username1":"User2",
"password1":"Pass2"
}
}
Prerequiste is:pip install --trusted-host pypi.python.org robotframework-httplibrary
先决条件是：pip install --trusted-host pypi.python.org robotsframework-httplibrary

I had similar issue and this work fine with me:
${json} Get Binary File${json_path}nameOfJsonFile.json
我有类似的问题，这对我来说很好用：
${json} Get Binary File${json_path}nameOfJsonFile.json
It works for me on API testing, to read .json and POST, like here
它适用于我的 API 测试，读取 .json 和 POST，就像这里
*** Settings ***
Library Collections
Library ExtendedRequestsLibrary
Library OperatingSystem
*** Variables ***
${uri} https://blabla.com/service/
${json_path} C:/home/user/project/src/json/
*** Test Cases ***
Name of Robot Test Case
Create Session alias ${uri}
&{headers} Create Dictionary Content-Type=application/json; charset=utf-8
${json} Get Binary File ${json_path}nameOfJsonFile.json
${resp} Post Request alias data=${shiftB} headers=${headers}
Should Be Equal As Strings ${resp.status_code} 200
There are also cases when you will need to transform read binary file (in my case ${json} to a dictionary but first try this simple solution.
在某些情况下，您需要将读取的二进制文件（在我的情况下为 ${json} 转换为字典，但首先尝试这个简单的解决方案。
