问题
I'm using jMeter to shoot json through post requests to my test server.
the following request always fail:
{ "location": { "latitude": "37.390737", "longitude": "-121.973864" }, "category": "Café & Bakeries" }
the error message in the response data is: Invalid UTF-8 middle byte 0x20 at [Source: org.apache.catalina.connector.CoyoteInputStream@6073ddf0; line: 6, column: 20]
the request is not sent to the server at all. other requests (e.g. replacing the value in category with other valid category like "Delis") works perfectly.
I guess it's an encoding issue related to "Café" but I don't know how to resolve it. any idea? Thanks!
回答1:
in the HTTP request itself, it is possible to set "content encoding". I set there "utf-8" and it solved the problem
回答2:
You'll probably need an HTTP header to post that JSON:
Content-Type: application/json; charset=utf-8
Without this, it's likely that the string isn't UTF-8–encoded. JSON should be in UTF-8, so the hex bytes for é should be 0xc3 0xa9.
Without that header, the byte sequence is probably 0xe9, which is in ISO-8859-1 encoding. That would explain the error, as UTF-8 sequences starting 0xe_ are 3-byte sequences, so it sees 0xe9 0x20 (where 0x20 is the space after the é) and complains about an "invalid middle byte".

None of the above solutions worked for me in jmeter 5.2.1
What I tried?
- Set the jmeter properties file: sampleresult.default.encoding=UTF-8 (Didn't work)
- Set the header Content-Type=application/json;UTF-8 ( Didn't work)
- Tried preProcessor sampler.getArguments().getArgument(0).setValue(new String(utf8Bytes)) ( Didn't work)
- Fortunately I noticed a field "Content encoding" ( As mentioned by Ofir Kolar) which seem to worked finally
