Axios 在使用 React 本机 Expo 发送表单数据时显示错误：“Err_Bad_Request”

Question

嗨，我正在尝试使用 formdata 将图像（缓冲区数据）和一些字符串发送到节点 js 和使用 expo react native 的 mongo db。但是有些我无法使用前端发送数据，但是我的代码与 Post man.I 配合得很好。我在下面分享我的代码并分享我的错误。我的错误在错误块中的控制台中显示数据，但没有将其发布到数据库这里是我的前端代码：

前端.js

export default class Sellnow extends Component {
  constructor(props) {
    super(props);
    this.onChangePetName = this.onChangePetName.bind(this);
    this.onChangePetTitle = this.onChangePetTitle.bind(this);
    this.onChangePetContact = this.onChangePetContact.bind(this);
    this.onChangePetPrice = this.onChangePetPrice.bind(this);
    this.onChangePetDescription = this.onChangePetDescription.bind(this);
    this.onValueChangeCat= this.onValueChangeCat.bind(this);
    this.onValueChangeCity= this.onValueChangeCity.bind(this);
    this.onFileChange = this.onFileChange.bind(this);
    this.onSubmit = this.onSubmit.bind(this);
    this.state = {
      name: "",
      title: "",
      contact: "",
      price: "",
      description: "",
      selectedcat:"",
      selectedcity:"",
      imgforsell:"",

      category: [
        
        {

        },

        },
        {
          itemName: "Pets Products"
        },
        {
          itemName: "Pets Accessories"
        }
      ],

      cityCategory:[


        {
          itemName: "Select City...."
        },
        {
          itemName: "Islamabad"
        },
        {
          itemName: "Rawalpindi"
        },
        {
          itemName: "Lahore"
        },
        {

        },
        {

        },
        {
          itemName: "Quetta"
        }

      ]
    };
  }


  onChangePetName(e) {
    this.setState({ name: e.target.value });
  }
  onChangePetTitle(e) {
    this.setState({ title: e.target.value });
  }
  onChangePetContact(e) {
    this.setState({ contact: e.target.value });
  }
  onChangePetPrice(e) {
    this.setState({ price: e.target.value });
  }
  onChangePetDescription(e) {
    this.setState({ description: e.target.value });
  }
  // categories function
  onValueChangeCat(e) {
    this.setState({ selectedcat: e.targetvalue })
  }

  // city function
  onValueChangeCity(e) {
    this.setState({ selectedcity: e.targetvalue })
  }

  onFileChange(e) {
    this.setState({ imgforsell: e.targetvalue})}

  // uploading Image


  _getPhotoLibrary = async () => {
    let result = await ImagePicker.launchImageLibraryAsync({
      allowsEditing: true,
      base64: true,
      exif: true,
      aspect: [4, 3]
    });

    

    if (!result.cancelled) {
      this.setState({ imgforsell: result });
      
      
    }
    this.props.navigation.setParams({
      imgforsell: this.state.imgforsell
    });
  };

 


  async onSubmit() {




       const FormData = global.FormData;
      const formData = new FormData();
      formData.append("name", this.state.name);
      
      
      formData.append("title", this.state.title);

      
      formData.append("contact", this.state.contact);

     
      formData.append("price", this.state.price);

     
       formData.append("description", this.state.description);

     
      formData.append("selectedcat", this.state.selectedcat);

     
       formData.append("selectedcity", this.state.selectedcity);


    
    formData.append("imgforsell",this.state.imgforsell)


      
     


      
    
      

axios
.postForm(
  `http://192.168.88.45:4040/pets/addpets `,
 QueryString.stringify({formData}),
 {
  headers: {
    'Content-Type': 'multipart/form-data',
    'Accept': 'application/json'
  },
},
)
.then(({ data }) => {
  console.log(data);
})
.catch((err) => {
  console.error(err.toJSON());
 
})
/*.finally(() => {
  this.setState({
    name: "",
    title: "",

    price: "",

    imgforsell: "",
  });
});*/
  }

  

  

  render() {
   
    const {imgforsell} = this.state
    
  
   

这是错误：

我猜你是在 formData 中发送一个图像，但你必须在 formData 的文件属性中添加type: 'image/jpeg',以解决这个问题

formData.append("imgforsell",this.state.imgforsell)

以此改变

formData.append('imgforsell', {
  uri: "file://" //Your Image File Path
  type: 'image/jpeg',
  name: 'imageName'
})
