Lua HTTPc:request_uri 函数设置请求参数 - 详细指南

在Lua中，可以使用httpc:request_uri函数来发送HTTP请求，并设置请求参数。该函数的语法如下：\n\nlua\nhttpc:request_uri(url, options)\n\n\n其中，url是要发送请求的URL地址，options是一个Lua table，用于设置请求参数。\n\n以下是一些常见的请求参数设置：\n\n1. method：设置请求方法，如GET、POST等，默认为GET。\nlua\noptions = {\n method = "POST"\n}\n\n\n2. headers：设置请求头信息，以Lua table的形式提供。\nlua\noptions = {\n headers = {\n ["Content-Type"] = "application/json",\n ["Authorization"] = "Bearer token"\n }\n}\n\n\n3. body：设置请求体，可以是字符串或者Lua table。\nlua\noptions = {\n body = "param1=value1&param2=value2"\n}\n\n\n4. query：设置查询参数，以Lua table的形式提供。\nlua\noptions = {\n query = {\n param1 = "value1",\n param2 = "value2"\n }\n}\n\n\n5. ssl_verify = false：设置是否验证SSL证书，默认为true。如果要忽略SSL证书验证，可以设置为false。\n\n使用示例：\nlua\nlocal httpc = require("resty.http").new()\n\nlocal options = {\n method = "POST",\n headers = {\n ["Content-Type"] = "application/json",\n ["Authorization"] = "Bearer token"\n },\n body = "param1=value1&param2=value2",\n query = {\n param3 = "value3",\n param4 = "value4"\n },\n ssl_verify = false\n}\n\nlocal res, err = httpc:request_uri("http://example.com/api", options)\nif not res then\n ngx.log(ngx.ERR, "failed to send request: ", err)\n return\nend\n\ngx.say(res.body)\n\n\n以上示例中，设置了请求方法为POST，请求头包含Content-Type和Authorization字段，请求体为param1=value1&param2=value2，查询参数为param3=value3&param4=value4，同时忽略了SSL证书验证。
