MultiPartEntityBuilder 中的实体 returns 错误

Question

我试过点击链接，但 none 个链接帮助解决了问题。

代码如下

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(Utility.AddProductWS);

MultipartEntityBuilder multipartBuilder = MultipartEntityBuilder.create();

/* example for setting a HttpMultipartMode */
multipartBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

for (int i = 0; i < photos.size(); i++) {

    multipartBuilder.addBinaryBody("images[]", newFile(photos.get(i).getImagePath());
}

multipartBuilder.addTextBody("username", username.toString());
multipartBuilder.addTextBody("accept_best_offer", String.valueOf(acceptOffer.isChecked() ? 1 : 0));
multipartBuilder.addTextBody("accept_trade", String.valueOf(acceptTrade.isChecked() ? 1 : 0));
multipartBuilder.addTextBody("product_price", etProductPrice.getText().toString());
multipartBuilder.addTextBody("product_description", etProductDescription.getText().toString());

HttpEntity httpEntity = multipartBuilder.build();
httpPost.setEntity(httpEntity);  // Error line
HttpResponse response = httpClient.execute(httpPost);
Utility.showLog(TAG, EntityUtils.toString(response.getEntity()));

错误

Caused by: java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/message/BasicHeaderValueFormatter; in class Lorg/apache/http/message/BasicHeaderValueFormatter; or its superclasses (declaration of 'org.apache.http.message.BasicHeaderValueFormatter' appears in /system/framework/ext.jar)

我正在使用 httpcore-4.4.1 和 httpmime-4.4.1 库文件。

Answer 1

multipartBuilder.addPart("images[]", 文件正文); fileBody 转换为 byteArray 然后你通过，因为数据在字节数组中传输

Try to upload the image in php server but it could post. in android

Answer 2

终于解决了

这是一个库问题，它适用于 4.3.1 版本。

这是 link 到 download 库文件

Answer 3

试试这些版本，对我有用

compile 'org.apache.httpcomponents:httpcore:4.3.3'
compile('org.apache.httpcomponents:httpmime:4.3.6') {
    exclude module: 'httpclient'
}
