HTTP高级请求 - HttpRequestEx ​

函数简介 ​

高级HTTP请求，支持自定义Method、请求头（含Cookie）、请求体。

接口名称 ​

HttpRequestEx

DLL调用 ​

c
const char* HttpRequestEx(int64_t instance, const char* method, const char* url, const char* headers, const char* body, const char* content_type, int32_t* status_code);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
method字符串方法，如"GET"/"POST"/"PUT"/"DELETE"，大小写不敏感。
url字符串完整URL。
headers字符串自定义请求头，多行字符串，每行"Name: Value"，可为空。
body字符串请求体，GET可传空。
content_type字符串如"application/json"，可为空。
status_code整数型指针输出HTTP状态码，可为NULL。

使用场景 ​

场景method关键参数
Bearer Token 鉴权GET/POSTheaders 含 Authorization: Bearer xxx
带 Cookie 请求GET/POSTheaders 含 Cookie: session=abc
REST 更新/删除PUT/DELETEbody + content_type
需要判断状态码任意传入 status_code 输出参数

headers 格式：每行 Name: Value，以 \r\n 分隔。示例：

Authorization: Bearer your_token_here
User-Agent: OLAPlug/1.0
Accept: application/json

完整示例见 网络使用指南。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
// 自定义 Header（含 Bearer Token）
string headers =
    "Authorization: Bearer your_token_here\r\n"
    "User-Agent: OLAPlug/1.0\r\n"
    "Accept: application/json";
int status = 0;
string resp = ola.HttpRequestEx(
    "GET",
    "https://api.example.com/v1/user/profile",
    headers, "", "", status
);
// status 为 HTTP 状态码（200/401/404 等）
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string headers = "Authorization: Bearer your_token_here\r\nUser-Agent: OLAPlug/1.0";
int status = 0;
string resp = ola.HttpRequestEx("GET", "https://api.example.com/v1/user/profile", headers, "", "", status);
python
from OLAPlugServer import OLAPlugServer

status = 0
resp = ola.HttpRequestEx("GET", "https://api.example.com/v1/user/profile", headers, "", "", status)
java

OLAPlugServer ola = new OLAPlugServer();
String headers = "Authorization: Bearer your_token_here\r\nUser-Agent: OLAPlug/1.0";
int status = 0;
String resp = ola.HttpRequestEx("GET", "https://api.example.com/v1/user/profile", headers, "", "", status);
go

ola, _ := olaplug.NewOLAPlugServer("OLAPlug_x64.dll")
defer ola.ReleaseObj()
status := 0
resp := ola.HttpRequestEx("GET", "https://api.example.com/v1/user/profile", "Authorization: Bearer token\r\n", "", "", status)

let status = 0;
let resp = ola.http_request_ex("GET", "https://api.example.com/v1/user/profile", "Authorization: Bearer token\r\n", "", "", &status);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
int status = 0;
long respPtr = HttpRequestEx(instance, "GET", "https://api.example.com/v1/user/profile", "Authorization: Bearer token\r\n", "", "", status);
if (respPtr != 0) FreeStringPtr(respPtr);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long HttpRequestEx(long ola, string method, string url, string headers, string body, string content_type, ref int status_code);

long instance = CreateCOLAPlugInterFace();
int status = 0;
long respPtr = HttpRequestEx(instance, "GET", "https://api.example.com/v1/user/profile", "Authorization: Bearer token\r\n", "", "", status);
if (respPtr != 0) FreeStringPtr(respPtr);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
int status = 0;
long respPtr = HttpRequestEx(instance, "GET", "https://api.example.com/v1/user/profile", "Authorization: Bearer token\r\n", "", "", status);
if (respPtr != 0) FreeStringPtr(respPtr);

返回值 ​

返回值说明
（返回值）字符串指针，返回响应体内容，失败返回NULL。需调用 FreeStringPtr 释放内存。

注意事项 ​

项目说明
释放内存返回的字符串需要调用 FreeStringPtr 释放内存。
headers格式每行"Name: Value"，以"\r\n"分隔。
支持的HTTP方法GET、POST、PUT、DELETE、PATCH、HEAD、OPTIONS等。
status_code可以为NULLstatus_code可以为NULL，如果不需要获取状态码。
