为什么我上传照片到LinkedIn API时会出现客户端错误？

我正在使用LinkedIn v2 api进行图像共享。有三个步骤，根据

注册要上载的图像

将您的图像上载到LinkedIn

创建图像共享

在完成步骤2之后，我用/v2/assets/{assetid}检查上传的状态，并得到一个“CLIENT_ERROR”。我不知道这意味着什么，也没有在LinkedIn文档或在线上找到太多关于它的信息。它可能与按照LinkedIn的要求上传一个二进制图像文件有关，但据我所知，我正在上传一个

编辑：下面是我用来上传图片的php curl。$uploadUrl是从映像寄存器获得的（步骤1）

资产API正在返回：

> GET /v2/assets/{redacted} HTTP/1.1
User-Agent: curl/7.35.0
Host: api.linkedin.com
Accept: */*
Authorization: Bearer {redacted}

更新：使用命令行curl上传图像时效果良好：

curl -i --upload-file {file} --header "Authorization: Bearer {auth}" {url}

更新：解决方案：

使用file_get_contents：curl_setopt（$ch，CURLOPT_POSTFIELDS，file_get_contents（{图像路径））；**

---

这个：curl\u setopt（$ch，CURLOPT\u POSTFIELDS，file\u get\u contents（{图像路径））；

    $ch = curl_init($uploadUrl);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch,CURLOPT_USERAGENT,'curl/7.35.0');
    $authorizationHeader = trim("Authorization: Bearer $accessToken");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array($authorizationHeader,"Content-Type: {$mimeType}","X-Restli-Protocol-Version: 2.0.0"));
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);

    curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents({path-to-your-image));
    $response = curl_exec($ch);

将头添加到代码中，作为

内容类型：应用程序/octet流
授权：承载${access\u token}

“X-Restli-Protocol-Version”：“2.0.0”

“内容类型”：“图像/jpg”

body只是图像文件内容或BLOB

方法：POST或PUT…我猜其中一个对某些人有效，第二个对其他人有效
你是如何上传你的图像的？你从/assets API收到了什么HTTP响应和头文件？更新：当我使用命令行curl上传图像时效果很好：（curl-i--upload file{file}--header“Authorization:Bearer{auth}{url}”对我来说，上传文件时，通过提供正确的
内容类型
标题，已修复了
客户端错误
状态。这似乎无法修复OP的问题，但可能会帮助其他人！
