您可以使用XMLHttpRequest（）

例如：

let formData = new FormData();
let fileName = "image1.png";

formData.append("file", {
  name: fileName,
  uri: img.uri,
  type: "image/png"
});

form.append("inputString", {
  appversion: this.state.appversion,
  mobile: this.state.mobile,
  token: this.state.token
});

var xhr = new XMLHttpRequest();

xhr.upload.onprogress = function(e) {
  var percentComplete = Math.ceil((e.loaded / e.total) * 100);
  // here you will get the percentage of upload completed.
};

xhr.open("POST", "https://fhy.appspot.com/customer/uploadfile");

xhr.onload = function() {
  if (xhr.status >= 200 && xhr.status < 300) {
    let resp = xhr.response;
    var response = JSON.parse(resp);
    //Response success
  } else {
    //Response error
  }
};

xhr.onerror = function() {
  //ERROR
};

xhr.setRequestHeader("Authorization", "dfg dfgdfgdfgdfgdfg"); //eg: `Bearer ${token}`
xhr.send(formData);

尝试将标题写入

  headers: {
    "Authorization", "dfg dfgdfgdfgdfgdfg";
    "content-type", "multipart/form-data";
  },
