在我的本机应用程序中,我想通过api上传图像,它在邮递员中工作,但不在应用程序中,总是给我“网络错误”

尝试将标题写为
headers: {
"Authorization", "dfg dfgdfgdfgdfgdfg");
"content-type", "multipart/form-data");
},

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);
