CURL escape single quote

I had the same problem. The simplest solution is to escape the apostrophe with a backslash in addition to wrapping it in a set of single quotes. '\''

For your use case, change Mary's to Mary'\''s and it should work.

curl -XPOST 'http://localhost:9290/location/place' -d '{"geoloc": {"lat": "38.1899", "lon": "-76.5087"}, "longitude": "-76.5087", "admin_name1": "Maryland", "admin_name2": "St. Mary'\''s", "admin_name3": "", "postal_code": "20692", "admin_code3": "", "country_code": "US", "admin_code1": "MD", "latitude": "38.1899", "admin_code2": "037", "accuracy": null, "place_name": "Valley Lee"}'

An alternate approach is to wrap the POST data (-d) in double quotes while escaping all nested occurrences of double quotes in the JSON string with a backslash.

curl -XPOST 'http://localhost:9290/location/place' -d "{\"geoloc\": {\"lat\": \"38.1899\", \"lon\": \"-76.5087\"}, \"longitude\": \"-76.5087\", \"admin_name1\": \"Maryland\", \"admin_name2\": \"St. Mary's\", \"admin_name3\": \"\", \"postal_code\": \"20692\", \"admin_code3\": \"\", \"country_code\": \"US\", \"admin_code1\": \"MD\", \"latitude\": \"38.1899\", \"admin_code2\": \"037\", \"accuracy\": null, \"place_name\": \"Valley Lee\"}"

Rule Of Thumb: In case you want explicitly representing single quote or double quotes in your string on bash, Use backslash (\) depends on your String Wrapper (should be in the same type). The backslash (\) character is used to escape characters that otherwise have a special meaning, such as newline, backslash itself, or the quote character.

Examples:

-Double Quote Example - Use \"

in case you want to print on bash She said "Yes I Do"

echo "She said \"Yes I Do\""#output:She said "Yes I Do"echo 'she said "Yes I Do"' #output:She said "Yes I Do"

-Single Quote example - Use '\''

in case you want to print on bash My Daughter's dog likes cat treats

echo "My Daughter's dog likes cat treats"#output:My Daughter's dog likes cat treatsecho 'My Daughter'\''s dog likes cat treats' #output:My Daughter's dog likes cat treats
