Node.js 带坐标的Mapbox反向地理编码

我目前正在研究 反向地理编码。我使用在mapbox文档中找到的示例。我的模式如下所示：

const mongoose = require("mongoose");

const PostSchema = new mongoose.Schema({
  title: {
    type: String,
    required: [true, "empty field"]
  },

  description: {
    type: String,
    required: [true, "empty field"]
  },
  images: [String],
  coordinates: Array,
  comments: [
    {
      type: mongoose.Schema.Types.ObjectId,
      ref: "Comment"
    }
  ],
  date: { type: Date, default: Date.now },
  views: { type: Number, default: 0 }
});

module.exports = mongoose.model("Post", PostSchema);

let title = req.body.title;
  let description = req.body.description;
  let content = req.body.content;
  let address = req.body.address;
  let city = req.body.city;
  let zip = req.body.zip_code;
  let region = req.body.region;

  geocodingClient
    .reverseGeocode{
      query: [address, city, zip, region],
      limit: 10
    })
    .send()
    .then(response => {
      const match = response.body;
      const coordinates = match.features[0].geometry.coordinates;
      const newPost = {
        title: title,
        description: description,
        content: content,
        images: images,
        coordinates: coordinates
      };

      Post.create(newPost)
        .then(newCreatedPost => {
          if (newCreatedPost) {
            res.redirect("/blog");
            console.log(newPost.coordinates);
          } else {
            res.send("where is the post");
          }
        })
        .catch(err => {
          // req.flash("error", err.message);
          // res.redirect("/blog/new");
          console.error(err.message);
        });
    });
}

然后我尝试从输入字段中获取位置

<% include ../partials/header %>
<div class="container">
  <div class="row">
    <div class="col-md-6">
      <form action="/blog" method="post" enctype="multipart/form-data">
        <div class="form-group">
          <label for="title-text">Title:</label>
          <input
            id="title-text"
            type="text"
            name="title"
            class="form-control"
            placeholder="title"
          />
        </div>

        <div class="form-group">
          <label for="description-text">Description:</label>
          <textarea
            id="description-text"

            name="description"
            id="textField"
            cols="30"

        </div>

        <div class="form-group">

          <input

            type="text"
            name="address"
            placeholder="1234 Main St"
          />
        </div>
        <div class="form-row">

当他试图创建一个新帖子时，会出现以下错误：

Error: query must be a string.

有没有人已经遇到过这样的问题，并且知道如何解决它。我将非常感激每一个提示

反向地理编码是关于将（纬度、经度）坐标转换为特征的。您的代码正在调用反向编码API，但正在传递正常的地理编码（地址）信息。这种反向地理编码对我来说很有效：

geocodingClient
  .reverseGeocode({
    query: [-58.5003038, -34.5741957]
  })
  .send()
  .then(response => {
     const match = response.body;
     console.log(response);
  })
  .catch(err => {
     console.error(err.message);
});

什么是geocodingClient？您能给我们指出文档吗？地理编码客户端看起来像这样：const mbxGeocoding=require（“@mapbox/mapbox sdk/services/Geocoding”）；const geocodingClient=mbxGeocoding（{accessToken:process.env.map\u Box\u Token}）；现在我明白了。在我看来，这是为了得到完整的地址，这就是为什么我尝试反向地理编码。我想我应该从response.body上取下整个地址。
