分享一下，看能帮助其它人吗，同样MethodNotAllowed错误，我发现不是服务器端问题，而是的客户端平台问题。我用的字节跳动的小程序平台：
data:是https://api.weixin.qq.com/tcb/uploadfile?access_token返回值
fileinfo：是tt.chooseImage后再tt.getImageInfo值
部分代码如下，核心思想是不能用tt.request方法，而是要用字节带的tt.uploadFile方法，就解决了，代码如下：
const fileSystemManager = tt.getFileSystemManager();
var filedata = fileSystemManager.readFileSync(fileinfo.path, "base64");
tt.uploadFile({
url: data.url,
filePath: fileinfo.path,
contentType: "multipart/form-data; charset=utf-8; boundary=__X_PAW_BOUNDARY__",
name: "file",
formData: {
"Signature": data.authorization,
"key": filepath,
"x-cos-security-token": data.token,
"x-cos-meta-fileid": data.cos_file_id,
"file": {
value: filedata,
options: {
filename: filename,
contentType: fileinfo.type
}
}
},
success(res) {
console.log("uploadfile 调用成功", res);
// if (res.data.errcode != 0) {
// reject(res.data);
// } else {
resolve(res);
// }
},
fail(err) {
console.log("uploadfile 调用失败:", err);
reject(err);
}
})
能发帖求助的肯定找了很久问题，我是这个问题我觉得很隐蔽了，这个解决了就上传成功了，特意来回复下！contentType后要带上 boundary=---XXXXXX
就是这样：
contentType":"multipart/form-data; boundary=---------------------------7db1851cd1158",
__X_PAW_BOUNDARY_ 这个值是什么？
