How to deal with garbled characters in the request content
-
1 Content-encoding: utf-8
-
2 Add encoding to the request header
Content-Type: application/json;charset=utf-8
-
3 When the request body is the parameter type, check the parameter "Encoding", and the encoding is the
urlencodedencoding. When the parameter value is non-character (Chinese characters, special symbols), you need to check the encoding
What to do when the response content is garbled
Modify the value in jmeter.properties to the sampler.result.encodingcorresponding code.
Sometimes the same interface is encountered, and the response is normal with postman requests, but garbled characters appear when responding to Chinese with Jmeter. Because: Jmeter encoding is based on the encoding of the operating system, in China, the character set encoding of Windows system is gbk936; the Chinese encoding of mac system is utf8.

The current http protocol version is 1.1, which is a long connection, so KeepAlive is checked by default, but in the performance test, this check will be removed as needed.
User-Defined Variables and User Parameters
User-defined variables are global variables with scope for the entire test plan. The value is fetched once when the run is started, during the run, the value is not fetched dynamically. That is, this value remains unchanged during operation. Even with multithreading, there is only one value.
User parameters are local variables, scoped to the current thread group or the current sampler. The value is obtained once when the operation is started, and the value can be obtained dynamically during the operation.
