我在为学校做一个小项目。我需要将PHP-cUrl文件转换为C#。
不知怎么,我解决不了这个问题,我用了谷歌,但没有帮上忙。我使用libcurl.NET绑定来解决这个问题,但对我来说没有机会。
现在我想问你能不能帮我解决我的问题。我需要将此代码转换为:
<?php
class Curl {
const METHOD_GET = 'GET';
const METHOD_POST = 'POST';
const METHOD_PUT = 'PUT';
const METHOD_DELETE = 'DELETE';
const CURL_TIMEOUT_IN_SECS = 15;
public static $successFullHttpCodes = array(200, 201, 204);
public function call($url, $urlParams = array(), $postParams = null, $method = self::METHOD_GET, $headers = array()) {
$finalUrl = $url . $this->getUrlParameterString($urlParams);
$data = $this->makeCurlCall($finalUrl, $postParams, $method, $headers);
return $data;
}
/**
* Creates a curl call for the given url, automatically validates the return value for errors.
* If an error has been found a new Exception will be thrown.
*
* @param string $url
* @param array $postParams Parameters for Post and Put-Requests
* @param string $method HTTP-Method (GET, PUT, POST, DELETE)
* @param string $headers HTTP-Headers
* @throws Exception
*/
private function makeCurlCall($url, $postParams = array(), $method = self::METHOD_GET, $headers = array()) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_VERBOSE, 0);
curl_setopt($curl, CURLOPT_TIMEOUT, self::CURL_TIMEOUT_IN_SECS);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
if ($headers) {
$usableHeaders = array();
foreach ($headers as $name => $value) {
$usableHeaders[] = sprintf('%s: %s', $name, $value);
}
curl_setopt($curl, CURLOPT_HTTPHEADER, $usableHeaders);
}
if ($postParams) {
curl_setopt($curl, CURLOPT_POSTFIELDS, $postParams);
}
$data = curl_exec($curl);
$this->checkForError($curl, $data);
return $data;
}
/**
* Checks for any errors in the api response.
* If an error has been found a new Exception will be thrown.
*
* @param string $data the resulting data
* @throws Exception
*/
private function checkForError($curl, $data) {
$curlInfo = curl_getinfo($curl);
if (isset($curlInfo['http_code']) && !in_array($curlInfo['http_code'], self::$successFullHttpCodes)) {
throw new Exception($curlInfo['http_code'] ? $data : 'could not get a response from the service', $curlInfo['http_code'] ? $curlInfo['http_code'] : 500);
}
}
/**
* Builds a valid http query
*
* @param array $urlParams
* @return string
*/
private function getUrlParameterString(array $urlParams) {
if (!$urlParams) {
return "";
}
return "?" . http_build_query($urlParams);
}
}
?>需要将此文件1转换为1才能在我的项目中使用它。
现在我得到了这个C#代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SeasideResearch.LibCurlNet;
namespace ConsoleApplication1
{
class CurlCall
{
const String method_get = "GET";
const String method_post = "POST";
const String method_put = "PUT";
const String method_delete = "DELETE";
const int curl_timeout_in_secs = 15;
public static int[] successFullHttpCodes = { 200, 201, 204 };
public String call(String url, String[] urlParams, String postParams, String method, String[] header)
{
String data = "";
String finalUrl = "";
finalUrl = url + this.getUrlParameterString(urlParams);
return data;
}
private String makeCurlCall(String url, String[] postParams, String method, String[] header)
{
try
{
Curl.GlobalInit((int)CURLinitFlag.CURL_GLOBAL_ALL);
Easy easy = new Easy();
Easy.WriteFunction wf = OnWriteData;
easy.SetOpt(CURLoption.CURLOPT_SSL_VERIFYPEER, 0);
easy.SetOpt(CURLoption.CURLOPT_SSL_VERIFYHOST, 2);
easy.SetOpt(CURLoption.CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
easy.SetOpt(CURLoption.CURLOPT_WRITEFUNCTION, wf);
easy.SetOpt(CURLoption.CURLOPT_URL, "http://google.com/index.html");
easy.SetOpt(CURLoption.CURLOPT_VERBOSE, 0);
easy.SetOpt(CURLoption.CURLOPT_TIMEOUT, curl_timeout_in_secs);
easy.SetOpt(CURLoption.CURLOPT_CUSTOMREQUEST, method);
if(header != null)
{
String[] usableHeaders;
for(int i = 0; i <= header.Length; i++)
{
usableHeaders[i] = string.Format("%s: %s", header[i], i);
}
easy.SetOpt(CURLoption.CURLOPT_HTTPHEADER, usableHeaders);
}
if (postParams != null)
{
easy.SetOpt(CURLoption.CURLOPT_POSTFIELDS, postParams);
}
easy.Perform();
easy.Cleanup();
Curl.GlobalCleanup();
}
catch (Exception ex)
{
Console.WriteLine(ex);
Console.ReadKey();
}
String data;
data = "0";
this.checkForError("", data);
return data;
}
private void checkForError(String curl, String data)
{
String curlInfo;
Curl.GlobalInit((int)CURLinitFlag.CURL_GLOBAL_ALL);
Easy easy = new Easy();
curlinfo = easy.GetInfo(CURLINFO, curl);
if()
{
}
}
private String getUrlParameterString(String[] urlParams)
{
if(urlParams != null)
{
return "";
}
return "?";
}
public static Int32 OnWriteData(Byte[] buf, Int32 size, Int32 nmemb,
Object extraData)
{
Console.Write(System.Text.Encoding.UTF8.GetString(buf));
Console.ReadKey();
return size * nmemb;
}
}}
我无法转换这部分,我不理解自我::键。
$method = self::METHOD_GET也不知道我是不是把这部分改对了。
if ($headers) {
if ($postParams) {在这段代码中,我得到了一个错误。
$usableHeaders[] = sprintf('%s: %s', $name, $value);
Error: "Use of unassigned local variable 'usableHeaders'关于checkForError函数,我不明白$curl变量是什么.也不知道如何使用getinfo $curlInfo = curl_getinfo($curl);
我在这里找不到和这部分差不多的东西
http_build_query($urlParams);希望你们能帮我一把。
顺便请原谅我的英语。

我试着一个一个地回答:
我无法转换这部分,我不理解自我::键。
self::METHOD_GET指向类内部的const String method_get = "GET";,这样您就可以像this.method_get一样编写它。
也不知道我是不是把这部分改对了。
差不多吧。像这样一条线
if ($headers) {在C#中是这样的:
if (header != null && header.lenght > 0) { 这是不完整的,检查它是否是一个数组!$postParam参数也是如此。
在这段代码中,我得到了一个错误。
PHP还是C#?
对于checkForError函数,我不知道$curl变量是什么。
与依赖注入一样,您可以通过按值调用函数,将配置好的变量和所有的curl设置一起分配给函数。
也不知道使用getinfo $curlInfo = curl_getinfo($curl);
很棘手,我也知道,也许您可以在Microsoft中搜索,首先搜索卷曲,然后.我找到了一个链接,也许有帮助:http://uniapple.net/blog/?p=1992
在这里,我没有找到与这部分http_build_query($urlParams)相等的东西;
