设置 URL 路径参数

在请求级别设置 #

使用 SetPathParam 或 SetPathParams 可以在请求级别设置 URL 路径参数以替换路径中的变量:

client := req.C().EnableDebugLog().EnableDumpAllWithoutResponse()

client.R().
    SetPathParam("owner", "imroc"). // Set a path param, which will replace the vairable in url path
    SetPathParams(map[string]string{ // Set multiple path params at once
        "repo": "req",
        "path": "README.md",
    }).Get("https://api.github.com/repos/{owner}/{repo}/contents/{path}") // path parameter will replace path variable in the url

2022/05/20 10:59:22.916445 DEBUG [req] HTTP/2 GET https://api.github.com/repos/imroc/req/contents/README.md
:authority: api.github.com
:method: GET
:path: /repos/imroc/req/contents/README.md
:scheme: https
accept-encoding: gzip
user-agent: req/v3 (https://github.com/imroc/req)

在客户端级别设置 #

类似的, 你可以使用 SetCommonPathParam 或 SetCommonPathParams 在客户端级别设置 URL 路径参数，对所有请求生效:

client := req.C().DevMode().
    SetCommonPathParam(k1, v1).
    SetCommonPathParams(pathParams)

resp1, err := client.Get(url1)
...

resp2, err := client.Get(url2)
...
