I’m trying to formulate URL string in CURL request as:
curl -v --location --request GET "https://proxy-xxx.execute-api.ap-southeast-1.amazonaws.com/dev/proxy?path=\"https://target-xxx/api/v1/resource?q1=a&q2=b&q3=c\""
where I will pass "https://target-xxx/api/v1/resource?q1=a&q2=b&q3=c\" as query string to path variable in double quote.
Tested on API gateway console with path="https://target-xxx/api/v1/resource?q1=a&q2=b&q3=c" works fine.
However CURL hit bad request 400, and aws api gateway don’t have received. I believe URL syntax problem.
>Solution :
Quotations marks in the URL grammar do nothing special, do not mean a string literal. The first " does not mark unescaped string begin and the second " does not mark unescaped string end. You should url encode & characters to avoid splitting query params.
curl -v --location --request GET https://httpbin.org/get?path="https://target-xxx/api/v1/resource?q1=a%26q2=b%26q3=c"
Response:
{
"args": {
"path": "https://target-xxx/api/v1/resource?q1=a&q2=b&q3=c"
},
"headers": {
"Accept": "*/*",
"Host": "httpbin.org",
"User-Agent": "curl/7.79.1",
"X-Amzn-Trace-Id": "Root=1-6215a80a-5e94b80531a2f4076f84342e"
},
"url": "https://httpbin.org/get?path=https:%2F%2Ftarget-xxx%2Fapi%2Fv1%2Fresource%3Fq1=a%26q2=b%26q3=c"
}
If you wish path quoted
curl -v --location --request GET https://httpbin.org/get?path=\"https://target-xxx/api/v1/resource?q1=a%26q2=b%26q3=c\"
Response:
{
"args": {
"path": "path": "\"https://target-xxx/api/v1/resource?q1=a&q2=b&q3=c\""
},
"headers": {
"Accept": "*/*",
"Host": "httpbin.org",
"User-Agent": "curl/7.79.1",
"X-Amzn-Trace-Id": "Root=1-6215a9c5-11a283486ad54eb96c499bc7"
},
"url": "https://httpbin.org/get?path=\"https:%2F%2Ftarget-xxx%2Fapi%2Fv1%2Fresource%3Fq1=a%26q2=b%26q3=c\""
}
