    postman 可以跑通 http://cms.pactera.com:9097/upload/public/32/Other/1013100210-575550.png ,但是代码不会写肿么办,postman 生成的代码是这样的

    OkHttpClient client = new OkHttpClient();

    MediaType mediaType = MediaType.parse("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"); RequestBody body = RequestBody.create(mediaType, "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name="Domain"\r\n\r\nxsh\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name="IsPublic"\r\n\r\ntrue\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name="FileType"\r\n\r\nImage\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name="FileCategory"\r\n\r\nOther\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name="files"; filename="C:\Users\z1557\Pictures\aa.png"\r\nContent-Type: image/png\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--"); Request request = new Request.Builder() .url("http://cms.pactera.com:9097/api/services/app/Public/UploadFiles") .post(body) .addHeader("content-type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW") .addHeader("Content-Type", "application/x-www-form-urlencoded") .addHeader("Authorization", "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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.FFbs7JH0Fad1yY5On-ivZCDb8UO-yZ0SE-HMqYFgRjk") .addHeader("Cache-Control", "no-cache") .addHeader("Postman-Token", "c3d0193f-0e32-4c4e-9154-bec83f7d6a62") .build();

    Response response = client.newCall(request).execute();

    postman 的参数在这 Domain:xsh IsPublic:true FileType:Image FileCategory:Other

    不能直接前端直传么,还到后端倒手一次

    @Alexliu 别人写好的代码我接手的,客户要求换文件上传地址,我写到前端得全改一遍,所以想写一个名字参数列表和返回参数一样的方法算了
