【问题描述】：

我尝试在正文（data）中发送权限类型字段，但没有成功。

文档说明：在body上发送权限和角色。

文档链接：https://developers.google.com/drive/api/v3/reference/permissions/create

我得到了这个答案。

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "The permission type field is required.",
    "locationType": "other",
    "location": "permission.type"
   }
  ],
  "code": 400,
  "message": "The permission type field is required."
 }
}

这是我的代码结构，我将不胜感激。

const file = this.file;

        var FileID = "16omyu1bxFk1tVVMrpIcYQDC3sNYxSIg2";

        const fr = new FileReader();
        fr.readAsDataURL(file);
        fr.onload = function() {
          const boundary = "xxxxxxxxxx";
          let data = "--" + boundary + "\n";
          data += "Content-Type: application/json; charset=UTF-8\n\n";
          data += JSON.stringify({role: "reader", type: "anyone"}) + "\n";
          
        $.ajax({
            type: "POST",
            beforeSend: function(request) {
                request.setRequestHeader("Authorization", "Bearer" + " " + localStorage.getItem("accessToken"));
                request.setRequestHeader("Content-Type", "boundary=" + boundary); 
            },
            url: "https://www.googleapis.com/drive/v3/files/" + FileID + "/permissions",
            success: function (data) {
                console.log(data);
            },
            error: function (error) {
                console.log(error);
            },
            async: true,
            data: data,
            cache: false,
            processData: false,
            timeout: 60000
        });
    }

【解决方案1】：

我相信你的目标和情况如下。

您想使用 ajax 将权限创建为 {role: "reader", type: "anyone"}。
您的访问令牌可用于使用 Drive API 创建权限。

修改点：

在这种情况下，JSON.stringify({role: "reader", type: "anyone"})可以像请求头的data: JSON.stringify({role: "reader", type: "anyone"})一样直接使用。
请使用application/json作为请求头的内容类型。

当以上几点反映到你的脚本中时，它变成如下。

修改后的脚本：

从：

const boundary = "xxxxxxxxxx";
let data = "--" + boundary + "\n";
data += "Content-Type: application/json; charset=UTF-8\n\n";
data += JSON.stringify({role: "reader", type: "anyone"}) + "\n";
$.ajax({
    type: "POST",
    beforeSend: function(request) {
        request.setRequestHeader("Authorization", "Bearer" + " " + localStorage.getItem("accessToken"));
        request.setRequestHeader("Content-Type", "boundary=" + boundary); 
    },
    url: "https://www.googleapis.com/drive/v3/files/" + FileID + "/permissions",
    success: function (data) {
        console.log(data);
    },
    error: function (error) {
        console.log(error);
    },
    async: true,
    data: data,
    cache: false,
    processData: false,
    timeout: 60000
});

至：

$.ajax({
  type: "POST",
  beforeSend: function(request) {
    request.setRequestHeader("Authorization", "Bearer" + " " + localStorage.getItem("accessToken"));
    request.setRequestHeader("Content-Type", "application/json"); // Modified
  },
  url: "https://www.googleapis.com/drive/v3/files/" + FileID + "/permissions",
  success: function (data) {
    console.log(data);
  },
  error: function (error) {
    console.log(error);
  },
  async: true,
  data: JSON.stringify({role: "reader", type: "anyone"}), // Modified
  cache: false,
  processData: false,
  timeout: 60000
});
