Question

我正在尝试为从我的React应用程序上传的图像设置“ Cloudinary”。

我的提交功能始终响应：“错误的网关502”和“ SyntaxError：输入意外结束”。

我假设标题有问题，但是我找不到问题...

handleFileSelect = (e) => {
    this.formValid()
      this.setState({
        picture: e.target.files[0] })
  }




submit(){

    const CLOUDINARY_URL= 
    "https://api.cloudinary.com/v1_1/dvz27u2gu/image/upload"
    const CLOUDINARY_UPLOAD_PRESET= "jshvp3nh"
    

        const obj = Object.assign({}, this.state);
        const formData = new FormData();
        formData.append("file", obj.picture);
        formData.append("upload_preset", CLOUDINARY_UPLOAD_PRESET); 

        fetch(CLOUDINARY_URL,{ 
          mode: 'no-cors',
          method:'post',
          headers: { "Content-Type": "application/x-www-form-urlencoded"}, 
          body:formData,
        })
        .then((res)=>{return res.json()})
        .then(data=>console.log(data))
        .catch(err=>console.log(err));
}

Answer 1

您可以尝试以下操作：

<div><input type="file" onChange={this.submit}/></div>


submit = (e) => {

    var file = e.target.files[0];
    var data = new FormData();
    data.append('upload_preset', 'jshvp3nh');
    data.append('file', file);
    data.append('cloud_name', 'dvz27u2gu');

    const config = {
        method: "POST",
        body: data 
      };

     var imgurl = "https://api.cloudinary.com/v1_1/dvz27u2gu/raw/upload";
     fetch(imgurl, config)
        .then(responseData => {
           console.log('here');
           console.log(JSON.stringify(responseData, null, 4));
           console.log(responseData);
         })}

Answer 2

这就是我的工作方式。

    const CLOUDINARY_URL= "https://api.cloudinary.com/v1_1/dvz27u2gu/image/upload"
    const CLOUDINARY_UPLOAD_PRESET= "jshvp3nh"

        const obj = Object.assign({}, this.state);

        const formData = new FormData();
        formData.append("file", obj.picture);
        formData.append("api_key", "xx")
        formData.append("api_secret", "xx")
        formData.append("upload_preset", CLOUDINARY_UPLOAD_PRESET); 
        formData.append("timestamp", (Date.now() / 1000) | 0);


        fetch(CLOUDINARY_URL,{
            method:'POST',
            body: formData,
            
        })
        .then((res)=>{return res.json()})
        .then((data)=>{
            obj.img_url_cloudinary=data.secure_url; 
            this.sendForm(obj);
        }).catch(err=>console.log(err));;
