报表门户不将日志附加到报表

Question

我正在研究一种方法，将报告日志发送到报告门户，并附上屏幕截图。我正在使用XmlHttpRequest模块访问报表门户日志endpoint。这是我的密码。但是这段代码不起作用，相反，我得到了一条“json\u请求\u部分丢失”的响应消息。我做错了什么，我是按照这里的文件做的

  try {
    const request = new XMLHttpRequest();

    const body = {
    itemUuid: 'gsgasgh-dsjdbbdjsbd',
    launchUuid: 'hshu1qqqqjjhdh-ddjdh',
    time: '1555677888',
    message: 'failed',
    level: 40000,
    file: {
      name: 'screenshot.png',
    },

  };

    request.open('POST', `http://rp.com/my_project/log`, false); // `false` makes the request synchronous
    request.setRequestHeader('Content-Type', 'multipart/form-data');
    request.setRequestHeader('Authorization', `Bearer ${config.token}`);
    request.send(JSON.stringify(body));

    if (request.status >= 200 && request.status <= 299) {
      const { responseText } = request;
      console.log(responseText);
    } else {
      console.log(`Unexpected Response Returned: ${request.responseText}`);
    }
  } catch (error) {
    console.log(error.message);
  }
};

发送二进制数据有点复杂，您必须以特殊格式形成多部分请求。该格式在本指南中有很好的描述。请注意，请求的第一部分应该包含JSON，其中包含来自多部分的其他部分的日志消息和文件名称。此外，ReportPortal的团队已经实现了Javascript。你也可能会发现这个片段很有帮助：

    buildMultiPartStream(jsonPart, filePart, boundary) {
    const eol = "\r\n";
    const bx = `--${boundary}`;
    const buffers = [
        // eslint-disable-next-line function-paren-newline
        Buffer.from(
            // eslint-disable-next-line prefer-template
            bx + eol + "Content-Disposition: form-data; name=\"json_request_part\""
            + eol + "Content-Type: application/json" + eol
            + eol + eol + JSON.stringify(jsonPart) + eol,
        ),
        // eslint-disable-next-line function-paren-newline
        Buffer.from(
            // eslint-disable-next-line prefer-template
            bx + eol + "Content-Disposition: form-data; name=\"file\"; filename=\"" + filePart.name + "\"" + eol
            + "Content-Type: " + filePart.type + eol + eol,
        ),
        Buffer.from(filePart.content, 'base64'),
        Buffer.from(`${eol + bx}--${eol}`),
    ];
    return Buffer.concat(buffers);
}
