正在将图像发布到个人配置文件无效的请求参数

Question

无法通过共享终结点共享图像内容，图像资产是通过assets接口上载的，但我对直接从示例中复制的共享接口的请求此处https://docs.microsoft.com/en-us/linkedin/marketing/integrations/community-management/shares/share-api?context=linkedin/compliance/context#share-content返回错误，请求正文/Headers中的参数无效请参阅下面的详细信息。

看起来错误消息与标题有关。您的请求主体是JSON，但是您没有设置Content-Type头，所以这可能是问题所在：

Content-Type: application/json

通常，您需要一个Content-Length标头与之一起发送，但大多数时候，您用来发送请求的客户端会处理该标头的设置。

我不确定您是如何发出请求的，但这里有一个用JavaScript编写的fetch()示例(请确保在Authorization标头中放入正确的身份验证标记)：

const url = 'https://api.linkedin.com/v2/shares';

const requestBody = {
  "content": {
    "contentEntities": [
      {
        "entity": "urn:li:digitalmediaAsset:C5622AQEEn3mmqzCb5w"
      }
    ],
    "title": "Great Result",
    "landingPageUrl": "https://google.com.au",
    "shareMediaCategory": "IMAGE"
  },
  "distribution": {
    "linkedInDistributionTarget": {}
  },
  "owner": "urn:li:person:zzR_UbXjsG",
  "subject": "Great Result",
  "text": {
    "text": "Great result, couldn't have gone better #realestate"
  }
};

async function makeRequest(url, requestBody) {
  const response = await fetch(url, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer ***',
      'X-Restli-Protocol-Version': '2.0.0'
    },
    body: JSON.stringify(requestBody) // body data type must match "Content-Type" header
  });
  return await response.json(); // parses JSON response into native JavaScript objects
}

// make the actual request
makeRequest(url, requestBody);
