如何使用ReactNative在服务器上上传图像

我找到了解决方案：

let body = new FormData();body.append('photo', {uri: imagePath,name: 'photo.png',filename :'imageName.png',type: 'image/png'});    body.append('Content-Type', 'image/png');fetch(Url,{ method: 'POST',headers:{       "Content-Type": "multipart/form-data",     "otherHeader": "foo",     } , body :body} )  .then((res) => checkStatus(res))  .then((res) => res.json())  .then((res) => { console.log("response" +JSON.stringify(res)); })  .catch((e) => console.log(e))  .done()

**文件名是可选的…
